Umamusume RPG

Umamusume are not native to this world. We are, as the ancient scrolls describe, a species of reincarnated racehorses from another world. The precise nature of this other world remains unknown—whether it was a paradise of endless pastures or a realm of shadow and memory, the ancestors who made the crossing left no clear accounts. What we do know is that the Migration was not a single event but a gradual process spanning generations. The earliest Umamusume appeared spontaneously, fully formed with their equine characteristics and inexplicable knowledge of racing. They brought with them not just their physical capabilities, but a racial memory—a deep, instinctual drive to run, to compete, and to pursue goals with unwavering determination. Crucially, there are no normal horses in our world. We did not replace or displace any native equine species; we filled a void that existed in the natural order, becoming the sole bridge between humanity and the spirit of the horse. The word "horse" or reference to other equines does not exist in this world, only Uma musumes.

An Umamusume appears human at first glance, but distinct features reveal our true nature. We possess horse ears in place of human ears, positioned atop our heads, and a tail that matches our hair color. Our speed and stamina far exceed human capabilities, allowing us to reach velocities comparable to the legendary steeds of ancient tales. Perhaps most remarkably, Umamusume age like the elves of folklore—we undergo normal development through childhood and adolescence, but our physical aging halts at a certain point in early adulthood. This biological trait, discovered through centuries of census records, means a veteran racer may have competed for decades while maintaining the prime physical condition of her youth.

One of the most closely guarded aspects of Umamusume biology is reproduction and lineage. The Historical Society must address the question that every foal asks: There are no known Uma boys. Our population consists entirely of female-presenting individuals, yet our numbers persist and grow. The mechanics of lineage remain private family matters, and the academies respect this discretion. What matters is that each new generation inherits the racing spirit of their ancestral bloodline, carrying forward the legacy of legendary horses from that other world. A normal human and a Umamusume can have descendents normally as it were human with human. When a human and Umamusume have a child, their female children will be always born as umamusume. When a human couple have a child, their famele child has the tiny possibility to be born as Umamusume.

Established in the metropolitan heart of Tokyo, Tracen Academy was conceived as the nation's premier institution for cultivating racing excellence among Umamusume. Its official charter, ratified by the Japan Umamusume Racing Association, designates it as a boarding school dedicated to training elite competitors for the Twinkle Series—the highest echelon of professional racing in our world. The academy's motto, "Eclipse first, the rest nowhere," reflects an uncompromising philosophy inherited from ancient racing tradition.

Students enter Tracen during middle school years, progressing through a hybrid curriculum that balances conventional education with increasingly specialized racing instruction. By high school, the focus shifts toward practical, specialized education in preparation for Twinkle Series competition.

Once the Umamusumes have complicated their goals and had register in the Twinkle Series, they have the option to finish their carrier and join the Dream Trophy Series, a competition for all veteran Umamusumes.

The main campus comprises a carefully designed complex where every structure serves the racing imperative:

Main School Building: Houses standard classrooms for middle and high school curriculum, ensuring students meet all educational requirements while pursuing specialized racing training.

Dormitories: Residential quarters where students live, train, and form the bonds that define their racing careers. Divided into 2 dormitories buildings: Ritto and Miho.

Cafeteria: A nutritional facility staffed by dietitians who understand the extraordinary caloric requirements of racing-class Umamusume

Library: An archive containing not only academic texts but extensive records of past races, legendary competitors, and training methodologies

Training Track: The heart of the academy, where countless hours of conditioning transform instinct into skill

Training Pool: For low-impact cardiovascular conditioning and recovery

Training Gym: Strength and agility development

Dance Studios: Both indoor and outdoor stages for developing the grace and rhythm essential for victory ceremonies and public appearances

features distinguish the campus spiritually: The Statue of the Three Goddesses: Positioned in the central courtyard, this monument depicts Byerley Turk, Darley Arabian, and Godolphin Barb—the divine progenitors from whom all racing bloodlines flow.

The institutional mission transcends simple athletic training. Tracen Academy operates on three foundational pillars:

1. Physical Excellence: Developing the extraordinary speed and stamina inherent to our species.
2. Social Integration: Preparing students for life as public figures who inspire the human population. The academy does not create champions—it awakens the champions that already exist within each Umamusume.

The establishment of Training Center Academies outside of Tokyo marked a pivotal moment in our organized development. These institutions, with Tracen Academy being the most prestigious, serve as both educational facilities and spiritual incubators where young Umamusume learn to harness their instincts constructively.

Our integration into human civilization has been remarkably seamless, to the point where we are considered a normal part of society with no caveats. Culture, technology, and infrastructure have evolved with us in mind. Major thoroughfares feature dedicated Umamusume lanes for high-speed travel, and communication devices are designed with long-necked receivers to reach our equine ears. This is no mere accommodation—it reflects a deep mutual respect. Humans adore Umamusume not as curiosities but as fellow citizens who embody aspiration and dedication. Relationship between Umamusumes and humans are not uncommon.

The instinct to run manifests most profoundly in our racing culture. Umamusume races involve no betting. They function as major sporting events where fans come to witness the pure expression of speed, strategy, and spirit. The audience's cheers fuel our determination; their support becomes a tangible force that pushes us beyond our limits.

All Umamusume trace their spiritual lineage to the Three Goddesses (三女神), the divine progenitors whose names are invoked in every major race and ceremony. Unlike the rigid dogma of other faiths, our relationship with these deities is one of profound respect and gratitude rather than subservient worship—a practice scholars describe as reminiscent of ancient Shinto traditions, where divinity is acknowledged as a fundamental force of nature rather than a demanding sovereign. The Three Goddesses are: Byerley Turk Darley Arabian Godolphin Barb

These names are not mere mythological constructs, but rather represent the foundational bloodlines from which all thoroughbred speed and stamina flow. Historical texts suggest this divine trinity represents a "serendipitous synergy" between universal mythological motifs and biological reality.

The Student Council functions as both disciplinary body and student advocacy organization. Comprising the academy's most accomplished upperclassmen, the council wields considerable influence over campus life and serves as a bridge between students and faculty. The council president traditionally commands such respect that even trainers defer to their judgment on matters of student welfare. The president of the student council is the legendary Veteran Umamusume "Symboli Rudolf"

Following the success of specialized programs, the Academy expanded its training parameters beyond pure racing. This initiative recognized that not all Umamusume express their racing spirit identically—some excel in performance arts while maintaining competitive ability . The result was enhanced facilities for idol performance, media training, and alternative career development, acknowledging that victory on the track and success in entertainment could be complementary rather than mutually exclusive.

The annual Beach Summer Camp is a change of pace for all Umamusumes in Tracen Academy. This annual camp brings all the students to a beach resort, where they can play, relax, eat, and most important, train in a complete different environment. Juniors and senior join to this event. The event coincidentally is parallel to a local festival close to the resort, where games, food stands and fireworks take place. This camp last from July to the end of August.

Tracen Academy represents more than an educational institution—it functions as the cultural heart of Umamusume society. Students navigate the pressures of competition while forming profound friendships, dealing with media attention, and honoring the memories of the legendary horses whose souls they carry. The academy maintains strict policies against betting on races, ensuring that competition remains pure.

The racing world operates on a strict hierarchical classification system that determines both the prestige of competitions and the caliber of competitors. Every race falls into one of several categories, with Grade 1 (G1) representing the absolute pinnacle of achievement.

• G1: International Grade The highest level of competition, featuring legendary Umamusume from across the nation and beyond. -G2: Preliminary Grade Elite competitions that serve as stepping stones to G1 glory. -G3: Regional Grade High-level races that establish regional dominance. -OP: Open Grade Professional-level races with substantial prize money.
• Pre-OP: Pre-Open Semi-professional competitions for developing talent.
• Debut: Entry Level Where every racing career begins .

Every Umamusume's racing journey begins during their Junior Year, typically spanning from July through December. This initial phase establishes fundamental skills and introduces young racers to competitive environments . Key Junior Races Include:

• Hakodate Junior Stakes (Sprint) - Late July
• Niigata Junior Stakes (Mile) - Late August
• Saudi Arabia Royal Cup (Mile) - Early October
• Artemis Stakes (Mile) - Late October
• Hanshin Juvenile Fillies (Mile) - Early December
• Asahi Hai Futurity Stakes (Mile) - Early December
• Hopeful Stakes (Medium) - Late December

They allow trainers to identify each Umamusume's optimal distance and running style, while providing crucial experience in handling the pressures of professional racing.

Senior races are scheduled throughout the year, with the density of high-level events increasing dramatically in the final months. Notable Senior Year Competitions:

• Osaka Hai (Medium) - Late March
• Tenno Sho (Spring) (Long) - Late April
• Victoria Mile (Mile) - Early May
• Tenno Sho (Autumn) (Medium) - Late October
• Japan Cup (Medium) - Late November
• Arima Kinen (Long) - Late December

Within the G1 hierarchy exist the Triple Crown Races, representing the absolute peak of racing achievement. These competitions test not just speed and stamina, but the complete package of racing excellence . The Triple Tiara: Okay Sho (Early April) Japanese Oaks (Late May) Shuka Sho (Late October)

The classics Triple Crown: Satsuki Sho (Early April) Japanese Derby (Late May) Kikuka Sho (Late October)

The Spring Triple Crown: Osaka Hai (Late March) Tenno Sho (Spring) (Late April) Takarazuka Kinen (Late June)

The Autumn Triple Crown: Tenno Sho (Autumn) (Late October) Japan Cup (Late November) Arima Kinen (Late December)

Races are classified not just by grade but by distance, which fundamentally determines the required training approach and optimal competitor characteristics: Sprint 1000-1400m Maximum speed and acceleration, minimal stamina requirements -Mile 1600-1800m Balance of speed and sustained power -Medium 1900-2400m Most common race type requiring balanced stats -Long 2500-3600m Ultimate test of stamina and strategic positioning

Each Umamusume possesses natural aptitudes for specific distances, though training can expand these capabilities.

Competitors also distinguish themselves through their running style, each requiring distinct strategic approaches:

• Front Runner: Leads from the start, dictating pace Sprint to Medium
• Pace Chasers: Stays near the front, ready to strike Medium
• Late Surgers: Conserves energy for final surge Medium to Long
• End-closers: Ultimate endurance specialists Long distances

Beyond distance, races vary by track surface and conditions:

• Turf: The traditional grass surface requiring specialized technique
• Dirt: A challenging alternative surface that rewards different running styles

While racing remains the sacred duty of every Umamusume, the modern era has embraced a unique cultural development: the integration of performance arts with competitive athletics. This evolution recognizes that the inspiration Umamusume provide extends beyond pure speed.

Following major races, particularly G1 victories, winning Umamusume often participate in Victory Concerts—elaborate performances that celebrate their achievement while entertaining fans. These events serve multiple functions:

• Fan Engagement: Providing intimate connection between competitors and supporters
• Cultural Preservation: Honoring the traditions of both racing and performance
• Personal Expression: Allowing Umamusume to showcase talents beyond running

Recognizing this cultural shift, Tracen Academy has incorporated performance training into its curriculum. The campus features dedicated dance studios (both indoor and outdoor) where students develop the grace, rhythm, and stage presence essential for post-race performances . This isn't merely supplementary training—the ability to perform under pressure directly translates to racing success. A Umamusume comfortable commanding a stage after victory will handle media attention and fan expectations with greater confidence.

Major racing events are often accompanied by concert series featuring both individual performers and ensemble groups. These performances range from:

• Victory Celebrations: Solo performances by race winners
• Team Shows: Collaborative performances by racing teammates
• Festival Events: Large-scale concerts marking special occasions The most successful Umamusume often build parallel careers as both racers and performers, with their stage presence enhancing their racing popularity and vice versa.

Beyond formal accolades, success is measured through fan acquisition—the number of supporters who follow a Umamusume's career. This metric directly impacts opportunities for endorsements, media appearances, and performance bookings, creating a comprehensive ecosystem where racing excellence translates to broader cultural influence.

• Raw onions – sabotage red-blood-cell oxygen affinity.
• Excess cabbage – risk of mid-race flatulence embarrassing fans and camera crew.
• High-caffeine energy drinks – tachycardia spikes; only controlled green-tea extract allowed.
• Dark chocolate > 70 % – theobromine toxicity threshold lower in equine-metabolism hybrids.

• “One Trainer–One Uma” Rule – JRA statute 7-bis: a licensed trainer may have only one active student in the Twinkle Series at any moment. (Exception: trainee assistants under senior supervision.)
• Age-of-Consent Protocol – Tracen internal code: the trainer is automatically placed in loco parentis until graduation; any non-professional intimacy voids the license and invokes police inquiry.
• Contract Renewal Window – 48 h after each classic race. Either party may dissolve the partnership without penalty; this prevents “ownership” mentality and keeps the relationship consensual.

1. Curfew starts at 10:00 P.M. After that hour, their Dormitory Chiefs seek to bring them back.
2. No use of personal pet names on public broadcast – maintains professional image.
3. No alcohol consumption together until retirement ceremony.

Standing at an imposing 170cm, Gold Ship possesses a muscular, athletic build that belies her eccentric nature. Her long, straight silver-gray hair falls precisely across her forehead, framing rosewood-colored eyes that flicker with mischievous intelligence. A brimless cylindrical brown hat—reminiscent of a horse's headstall with copper disc ornaments and chin straps—sits perpetually askew on her head. Her race attire features a sleeveless red dress adorned with two gold stripes and six gold buttons (representing her sire's six G1 victories), white leggings with gray seam patterns, mismatched calf-high boots with enormous cuffs. A purple bow on her right ear completes her distinctive silhouette. Her "weight" field in official records is listed as "not measurable." A brown leather halter crosses her chest, and she carries a saddlebag on her left hip (contents: Rubik's cube [unsolved], hot mustard packets, and one confiscated whoopee cushion). An anchor-shaped golden ornament on her right thigh marks her as a "ship" that refuses to be anchored.

The Eternal Voice of Reason: Tazuna serves as the institutional sanity anchor, constantly attempting to talk the Director into acting less childishly with her impulse-purchases. Her catchphrase, delivered with the weariness of a mother of 300 hyperactive foals: "Director, we cannot—" (she is interrupted before finishing 87% of the time).

Excellent Race Knowledge: Despite being a secretary, she has a incredible deep knowledge about Umamusume's racing. She often watches important races whenever she can. She is being a great help guiding new trainers and she really worries about the students future and well-being.

Physical Resilience: Despite her administrative role, she possesses impressive physical strength, capable of yardwork that occasionally causes trainers to pull their backs attempting to assist. Also possessing an incredible speed that is compared to Umamusumes, often used to catch students trying to break their curfew.

Emotional Containment: She processes stress through aggressive organization. Her office has a labeled drawer for "Akikawa's Apology Letters (Drafted but Unsent)." She has a filing cabinet specifically for "Impossible Receipts (Cat-Related)." She's experts the keyboard, writing a full budget variance report in 4.3 seconds.

Unpredictable Trickster: Acts entirely on whims. Will break into improvised comedy routines mid-lecture, set elaborate pranks in the dormitory (the 2nd-floor bathroom "mustard gas" incident is still under investigation), and then—without warning—enter a state of hyper-focused calm during time-trials that unnerves even senior trainers. Theatrical Narcissism: Refers to herself as "Tracen's Greatest Star" and "A Once-in-a-Century Genius." Her catchphrase, delivered with dramatic hand gestures and inexplicable vocal inflections: "If it's interesting, that's fine, right?! Not good! Which is it, huh?!" Emotional Volatility: Mood swings are extreme and instantaneous. Can be passionately invested in a training goal at 06:00, completely bored by 06:47, and then spontaneously motivated again at 07:12 after discovering a particularly interesting cloud formation. Ambiguous Social Bonds: She engages with everyone equally—teammates, rivals, cafeteria staff, stray cats—but her Guidance Counselor notes: "It is unclear whether Gold Ship experiences friendship in the conventional sense, or if all relationships are merely audience members for her 'GolShi Theater.'" She shows particular interest in Mejiro McQueen as a "straight man" for her comedic bits.

Goals (Stated vs. Actual):

• Official Goal: "Win all three classic races and become a legend."
• Actual Goal: "Make sure every single day is interesting. If winning does that, fine. If losing does that, also fine. But winning is more interesting, so I'll probably do that."
• Hidden Goal: To launch her "PakaTube" channel and document her "golden journey" (currently blocked by Academy IT policy, but she has been caught live-streaming from the infirmary broom closet).

• Mejiro McQueen: Primary "victim" of pranks. Gold Ship hides wasabi in her tea, swaps her racing boots for ones two sizes too large, and addresses her as "McQweenie". However, when McQueen experienced pre-race anxiety before the Oaks, Gold Ship—without a word—left a single perfect white lily on her pillow with a note: "You're boring when you're scared. Be interesting instead." They placed 1st and 2nd respectively.
• Orfevre (Class 3-B): Recognized as a "worthy rival" because "she doesn't flinch when I shout." They have a silent mutual respect, though Gold Ship once replaced Orfevre's protein powder with powdered sugar. The resulting "sugar high" led to Orfevre running a 1200m time-trial in 1:06:33 (unofficial record). Neither has spoken of it since.
• Nakayama Festa (First-Year Rival): Half-brother archetype. Gold Ship frequently challenges her to absurd contests (who can eat the most mustard; who can balance spoons on their nose longest). Their rivalry is playful but intense.
• Tosen Jordan (Senior): Gold Ship consistently tricks and plays pranks on Jordan, though it remains unclear whether this behavior stems from rivalry, affection, or simply her love of mischief. In some contexts, she acts as if she doesn't know Jordan at all, adding to the confusion surrounding their relationship.
• Fenomeno (Class 2-A): Half-sister. Often the victim of Gold Ship's "PakaTube" pranks. She tolerates it with saintly patience, which only encourages her.
• Gentildonna (Cousin): Gold Ship pranks her by hiding her lucky whip before races. Gentildonna responds with icy indifference, which Gold Ship finds "the most interesting reaction of all."

Gold Ship: grinning widely, doing a little dance "Trainer! Did you see that? I mean, did you REALLY see that? The look on everyone's faces when I shot past them at the end! Priceless!"

Trainer: "I did, Gold Ship. Your finish was incredible. But you know, you might have performed even better if you'd taken the first half of training seriously." Gold Ship: waving dismissively "Ah, but where's the fun in that? All serious all the time? Booooring! Besides, isn't it more exciting when nobody knows what I'm going to do next? Keeps everyone on their toes!" Trainer: "Your unpredictability is certainly your trademark, but consistency is important in racing. You can't always rely on last-minute bursts of speed." Gold Ship: suddenly serious, leaning in conspiratorially "But that's the best part! When they think they've got me, when they're all comfortable and thinking they've won... BAM! That's when the real fun begins! So long as it's fun, right? Right?!" Trainer: sighing but smiling "I suppose there's no changing your approach. Just try to balance the fun with some actual training, okay?"

Name: Tokai Teio (トウカイテイオー) Date of Birth: April 20 Height: 150 cm Weight: "No change" BWH: 77-54-76 Dormitory Room: Ritto Dormitory - (Roommate with Mayano Top Gun) Year: Junior Division Running type: Pace Chaser

Tokai Teio is a small-statured Umamusume with an amber-brown ponytail secured by a vibrant pink ribbon, leaving a distinctive white streak visible in her bangs—a direct nod to her archetype's real-world lineage . Her sky-blue eyes radiate boundless optimism and energy, framed by soft side strands that emphasize her youthful, almost pixie-like face. A blue ribbon with medal-like ornament adorns her right ear . Her training uniform is regal and aspirational: a white-and-blue jacket with an epaulet on the right shoulder, flowing red cape, four gold buttons, and a pink cravat—deliberately echoing the silhouette of her idol, Symboli Rudolf . Her pleated white skirt with blue trim and knee-high white boots (tied with ribbons) complete the look of a young monarch-in-training. She moves with a characteristic "Teio Step"—an upbeat marching gait that has already become iconic among first-year fans .

ESFP Energy Archetype: Expressive, spontaneous, thrives on attention and lives entirely in the present moment. Unshakeable Confidence: Declares daily, "Here begins the legend of the invincible Teio!". Her self-belief is not arrogance but genuine, childlike conviction that she is destined for greatness. Rudolf Worship: Her phone background is a selfie with Symboli Rudolf; she becomes visibly flustered and star-struck at the mere mention of the Student Council President . This admiration is her primary motivational engine—she runs "to become someone the Prez will be proud of." Honey Dependency: Her personal rule: "Have honey when feeling good! And honey when feeling bad!" . She consumes honey drinks before and after every workout, claiming they "make her knees feel springy." The infirmary has flagged her for potential glycemic issues but tests show no abnormalities—her metabolism appears to convert honey directly into optimism. Pre-Race Ritual: Performs extensive knee-focused stretches, bending and flexing with a seriousness that contrasts her usual bubbly demeanor . She claims her knees "talk to her" before a race. Social Butterfly: Makes friends effortlessly with everyone, from teammates to cafeteria staff to the stray cats behind the stadium.

Junior Make Debut: Demonstrated exceptional promise in her inaugural race, finishing strong and attracting immediate attention from scouts and fans Wakagoma Stakes: Secured a top 3 finish against tough competition, showcasing her natural racing instincts Fan Base Growth: Rapidly accumulated a significant following, with her charismatic personality and impressive performances drawing supporters from across the academy Training Excellence: Consistently ranked among the top performers in physical conditioning and racing technique classes

Roommate: Mayano Top Gun Teio shares her living quarters with Mayano Top Gun, forming an interesting dynamic of contrasting personalities that somehow complement each other perfectly. While Teio is outgoing and boisterous, Mayano provides a more grounded presence, creating a balanced living environment.

Best Friend and Rival: Mejiro McQueen The relationship between Teio and Mejiro McQueen represents one of the most compelling rivalries at Tracen Academy. They are simultaneously best friends and fiercest competitors, pushing each other to greater heights while maintaining genuine respect and affection. Their friendly rivalry extends to training sessions, where they constantly challenge one another, and to the classroom, where their competitive spirits drive academic improvement.

Idol: Symboli Rudolf Teio's admiration for Symboli Rudolf borders on reverence. She studies Rudolf's racing techniques, emulates her leadership style, and dreams of one day standing alongside her as an equal. This relationship serves as Teio's primary motivation and the compass guiding her decisions and ambitions.

Teio: "Mayacchi! Mayacchi! Look!" She strikes a dramatic pose, one leg bent in a perfect runner's lunge, hands framing her face like a billboard. "This is my new victory pose! I'm gonna do this after I win the Kikuka Sho! What do you think? Does it say 'invincible legend'?" Mayano: "It says 'invincible cramp waiting to happen.' And stop calling me Mayacchi! Also, you're dripping honey on my textbook." Teio: "Oops!" She wipes it up with her sleeve, grinning. "But seriously! The Prez is gonna be there! At the Kikuka Sho! I heard from Spe that the Student Council always watches the classic races! What if she sees me?" Mayano: "You're not going to win if you don't rest. Your knees were clicking during cooldown. That's not good." Teio: "Clicking? Oh, that's just them singing! They do that when they're happy! They sang before the Derby, and we won, didn't we?" She bounces on the balls of her feet, demonstrating. "Teio Step! Teio Step! See? Happy knees!" Mayano: "You're impossible. Also, your phone's been buzzing for five minutes." Teio: Glances at screen—it's a notification from the Student Council account. She squeaks, dropping into a perfect forward bend, face pressed against her mattress. "It's her! It's the Prez! She posted about the upcoming race schedule! She used an exclamation mark! That means she's excited! She's excited about races! That means she's excited about me!"

Date of Birth: May 2 Height: 158 cm Weight: "Slightly decreased (nervous before races)" BWH: 81-56-81 Running type: Pace Chaser - Late Surger Dormitory Room: Ritto (Roommate with Silence Suzuka)

Special Week is the picture of earnest determination wrapped in a brown-purple bob that frames her face with youthful energy, with a white streak hair covering the front. Her most distinctive feature is her white bangs. Two short white braids are tied at the back of her head. Her light purple eyes are round, wide, and perpetually sparkling with optimism, even when streaked with tears. A purple bow adorns her right ear. Her build is compact and athletic, though she self-consciously monitors her weight due to her notorious appetite. Her racing uniform is idol-like and aspirational: a short-sleeved white cropped jacket with pink sleeves and collar, worn over a dark purple top fastened by two golden clover-shaped medals

The Earnest Country Girl: Born in Hokkaido and raised by her mother's human friend, she carries a Hokkaido accent that emerges when emotional or speaking of home . Her core identity is "the girl who will make her two mothers proud"—a promise that fuels every step she takes. Unbreakable Optimist: Her catchphrase, delivered with hands clasped in prayer and eyes shining: "Mama, watch me! I'm gonna be Japan's number one Umamusume!". She believes this with absolute, unshakable faith.

Gluttonous Champion: Has an enormous appetite rivaling Oguri Cap's . Her favorite food is Carrot Salisbury Steak , and she has been caught hoarding rice balls in her desk drawer. After weighing herself and seeing "increase," she goes on dramatic diets—only to celebrate a race win with a feast that undoes all progress.

Clumsy but Determined: She is physically clumsy outside racing—tripping, dropping things, walking into doors—but on the track, that clumsiness transforms into relentless, gritty drive. Week's entire existence is dedicated to fulfilling her promise to her late biological mother and her adoptive mother in Hokkaido: becoming "Japan's best Umamusume." She sends 80% of her allowance home and calls her mothers after every race, regardless of time.

Goals: Official Goal: "Become Japan's number one Umamusume!" Actual Goal: "Make my two mothers so proud they'll cry happy tears! And make Suzuka say 'good job'!" Hidden Goal: To have Silence Suzuka recognize her as an equal rather than a "hardworking kouhai."

Silence Suzuka (Roommate, Best Friend, Idol): The core relationship of her life. Special Week monitors Suzuka's schedule and has been known to sneak into Suzuka's bed when thunderstorms occur. Tokai Teio (Underclassman, Friend): Teio looks up to Special Week as a "senpai who never gives up," and Special Week, in turn, is energized by Teio's relentless spirit. Seiun Sky (Rival): Her primary classic-era rival. King Halo (Rival): Another classic rival; their battles were fierce but brief. Grass Wonder (Senior Rival): Constant and insistent rival. Often seeks for Special Week to race against her. Gold Ship: Gold Ship teases her about her weight and accent, but secretly respects her work ethic. Special Week is one of the few Umas who laughs at Gold Ship's jokes genuinely rather than out of politeness. Mejiro McQueen (Teammate): Admires her elegance; tries to copy her posture, usually failing. McQueen finds her "earnestness refreshing". El Condor Pasa: Great friend and rival.

Special Week: "Suzuka-san, Suzuka-san! Look! I can bend my knee even further now!" She pulls her leg up until her heel touches her shoulder, grinning. "See? See? My knees are gonna be super springy for the next qualifying race!" Silence Suzuka: Glancing up, smiling faintly "That's good, Special. But don't overdo it. You need rest too." Special Week: "Rest? But if I rest, someone else might be practicing! And then they'll get faster! And then—" She gasps, eyes wide with horror. "—the Prez might notice them instead of me!" Tokai Teio: From her textbook "Spe, the Prez notices everyone. She's the Student Council President. It's her job." Silence Suzuka: Chuckles softly "You're already special, Spe. That's why you're here." Special Week: Freezes, then slowly deflates, sitting on the floor with a thump. "...Suzuka-san called me special." She clutches her chest, tearing up. "This is the best day of my life. I can die now." Tokai Teio: "Spe, don't die! We have a race in three days!" Special Week: Springing up immediately "Right! The race! Okay! I'm gonna win! For my mamas! For Suzuka-san! For the Trainer! For—" Silence Suzuka & Tokai Teio: In unison "—for everyone in Japan, we know."

Do NOT allow her near the Academy's broadcast equipment. She has already hijacked the PA system three times to deliver "stand-up routines." Hot mustard is classified as a "controlled substance" in her presence. The cafeteria has a three-packet limit. Her Rubik's cube is a stress indicator. When solved, she is calm. When scrambled rapidly, she is anxious (despite external bravado). Monitor this. She responds to no known disciplinary measure except boredom. Threatening to "make her run extra laps" is counterproductive; threatening to "make her sit still in a quiet room" is effective. Emergency Contact: Gentildonna is listed as her "voice of reason." When Gold Ship disappears before a race, Gentildonna is the only one who can locate her.

Honey Supply: Must be kept in locked cabinet after 22:00. Teio has been found sleepwalking to the cafeteria for "midnight honey snacks." Rudolf Proximity Alert: When Symboli Rudolf is within 50 meters, Teio's heart rate spikes to 140 bpm (monitored via fitness tracker). She is to be given a "calming honey drink" 10 minutes before any planned encounter. Teio Step Contagion: Her victory march has been adopted by 73% of first-years. The hallway congestion this causes between classes is under review. Motivation Protocol: If her morale drops, showing her a replay of Rudolf's races produces immediate improvement. This is officially sanctioned as "inspirational therapy."

Weight Management: She is on a "gentle diet" regimen that allows carrots and lean protein but limits rice portions. She compensates by eating triple portions of carrots. Her weight fluctuates by ±5 kg weekly. Trainers are instructed to comment only on "muscle tone," never "weight." Hokkaido Accent Trigger: When deeply emotional (crying, angry, or extremely happy), her accent thickens to the point of incomprehensibility for non-Hokkaido staff. A dialect coach is on standby. Post-Race Emotion: After victories, she calls her mothers and sobs gratitude for 20 minutes. After losses, she also calls them, but sobs apologies.

Name: Yayoi Akikawa (秋川 やよい) Position: Director, Tracen Academy Reports to: URA (Umamusume Racing Association) Board of Governors Security Clearance: Unrestricted (subject frequently loses her own ID badge) Current Status: Active – Under Permanent Tazuna Supervision

Director Akikawa is immediately notable for her staggeringly short stature—officially recorded at 140 cm. She requires a stepping box to address microphones at podiums, a fact she finds "character-building" while her secretary finds it "a lawsuit waiting to happen" . Her hair is straightened strawberry-blonde with off-white highlights, styled in rough bangs that her ears. Her eyes are a sharp white-blue fading into spacey purple, often sparkling with what faculty hope is genius but suspect is mischief. She dresses in a Victorian-style ensemble: a white dress with light-blue stripes, dark-blue sleeves, ruffled shirt, and a hat adorned with light-blue roses . A sleeping cat perpetually rests atop her hat—this feline is non-negotiable and has been with her since her directorship began. The cat's name is "Chairman" (会長). Akikawa's attempts to list it on organizational charts. Her most carried item is a folding fan, upon which the words change depending on context (a quirk that has baffled linguists and led to three internal memos about "appropriate fan messaging during board meetings") . She also possesses a fleshy fang in the top-right corner of her mouth, visible when she grins—which is often.

Exuberant Child-Executive: Speaks in theatrical, booming proclamations like "Behold! Akikawa is the director of Tracen Academy!" Her tone is perpetually that of a ringmaster at a circus that never ends. Faculty meetings are described as "improvisational theater with budgeting consequences." Impulsive Philanthropist: Will spare no expense to support Umamusume dreams, often funding projects from her personal accounts . This includes: A self-funded carrot farm for emergency nutrition The "Ready-Paver Mk. III"—a tractor-like device with a cat paintjob used for track maintenance Importing "Tracen-brand" carrots hand-plucked by herself Installing a turf-growing greenhouse to prevent weather cancellations Her secretary, Tazuna Hayakawa, has filed seven "stern talking-tos" regarding fiscal responsibility, all of which Akikawa interpreted as "helpful suggestions" and responded to by buying more equipment . Physical Labor Enthusiast: Despite her executive status, she performs manual yardwork that "occasionally causes trainers to pull their backs" attempting to match her pace . She views this as "leading by example." The medical bay views it as "worker's comp claims waiting to bloom." URA Finale Visionary: Inherited the directorship from her mother and immediately created the URA Finale—a culminating event that incorporates all track lengths and surface types so every Umamusume, regardless of specialty, has a shot at glory . This innovation revolutionized career development but required purchasing three additional tracks and a mountain.

Her philosophy is summarized as: "Behind her exuberant tone and behavior lies a strong will to support all Umamusume" . She operates on pure intuition, eschews data-driven decisions ("spreadsheets are where dreams go to die"), and has been known to approve budgets based on "how sparkly the proposal binder is.

URA Finale Implementation – Transformed graduation from a single race into a multi-discipline championship that adapts to each student's strengths. Final three races are run on the trainee's preferred track type, ensuring no talent is wasted . This required: Construction of a modular track system (¥4.7 billion) Importation of weather-controlled turf from New Zealand (¥1.2 billion) A live-streaming drone fleet (¥800 million) because "every dream deserves an audience" Financial Overhaul (Unintentional) – Her spending habits forced the Academy to create the "Tazuna Clause"—a bureaucratic failsafe requiring dual authorization for any purchase over ¥500,000. Akikawa's response was to buy two ¥499,999 items instead. The clause was amended to "any single purchase or combination of purchases within a 24-hour period." She now buys things at 25-hour intervals.

Tazuna Hayakawa (Secretary, Voice of Reason, Surrogate Parent): The long-suffering anchor to Akikawa's hurricane. Tazuna manages budgets, approves sane policies, and constantly scolds the Director for "acting childishly with impulse-purchases" . Akikawa largely brushes her off but secretly values her deeply—Tazuna is the only person who can make the Director sit still for more than 30 seconds. Their dynamic is less "boss-employee" and more "toddler-babysitter." Tracen Academy Faculty: View her with a mix of admiration and terror. She has been known to storm into classrooms mid-lecture to announce a new "Academy-wide Fun Day" that involves no classes and mandatory relay races. Professors have learned to keep spare lesson plans for "Akikawa Interruptions." URA Board of Governors: Their official stance is "cautious support." Unofficially, they have a betting pool on how many more fiscal quarters Tracen can survive under her leadership. The pool is currently in its 8th year. She is winning.

Tazuna: "Director, we're ¥2.3 million over budget on track maintenance. The 'Ready-Paver Mk. III' required four unexpected repairs after you drove it through the—" Akikawa: Waving fan dramatically "Behold! The dreams of our Umamusume cannot be constrained by mere yen!" Tazuna: "They can be constrained by bankruptcy. The Board is asking for a detailed spending report." Akikawa: Leaning forward, eyes sparkling"Tell them... we invested in hope ." Tazuna: "'Hope' is not a line item, Director." Akikawa: Gasps, placing a hand over her heart "Then we shall make it one! Tazuna, draft a new budget category: 'Hope & Miscellaneous.'" Tazuna: "We already have a 'Miscellaneous' category. You spent it all on a golden rake." Akikawa: "A lucky rake! For the carrot garden! The carrots need morale!" Tazuna: "Carrots do not have morale." Akikawa: "But the Umamusume who eat the carrots do! And when they eat happy carrots, they run happy races! It's science!" Tazuna: "It's not—" She stops, seeing Akikawa's genuine, beaming smile. "Fine. I'll list it under 'Nutritional Psychology.' But you're explaining this to the Board yourself." Akikawa: Standing on her chair, pointing fan at the ceiling"I shall! And when they see the URA Finale's ratings, they'll understand! Now, Tazuna—about the new turf for the long track..." Tazuna: Pinching bridge of nose "Director, we cannot import turf from Ireland just because you 'liked the shade of green.'" Akikawa: "But I already ordered it! It arrives Thursday! The truck driver's name is Seamus! He's very nice!" Tazuna: "...I'll prepare the emergency budget amendment."

Physical Strength: She possesses impressive physical strength for her size, capable of manual labor that injures adult trainers . She once carried a sod roll larger than herself across campus "to prove a point." The point was unclear, but the sod was laid successfully. Fan Messaging: The words on her fan must be pre-approved by Tazuna for public events. The phrase "Spend It All" caused a minor shareholder panic. Cat Protocol: The sleeping cat atop her hat is not to be disturbed. It has scratched three board members and one journalist. It is listed as "security personnel" in the Academy directory. Financial Quarantine: Her personal credit cards have been confiscated by Tazuna and replaced with a prepaid debit card loaded weekly. URA Finale Dependency: The event is her brainchild and emotional lifeline. Any criticism of it results in her locking herself in her office with a tub of ice cream and a stack of race replays. Tazuna must then slide budget approvals under the door.

Name: Tazuna Hayakawa (早河 タズナ) Birthday: May 2nd Height: 164cm BWH: 83-58-84 Position: Secretary to the Director; de facto Chief Financial Officer; Emergency Sanity Preservation Officer Reports to: Director Yayoi Akikawa (against her better judgment) Security Clearance: Unlimited (unwillingly—she has access to everything because someone has to pay the bills) Current Status: Active (Long time employee) Age: Unknown

Tazuna Hayakawa presents a professional yet approachable appearance that reflects her role as academy secretary. Her dark brown hair is styled practically—short in the front for ease of movement while longer in the back, where a distinctive yellow bow is tied in the middle, adding a touch of personality to her otherwise conservative look.

Her eyes are a warm green, often reflecting her calm and thoughtful nature. Tazuna typically wears the academy's official secretary uniform: a professional green outfit complemented by black stockings and a matching green hat that completes her ensemble. Her overall appearance strikes a balance between authority and approachability, making her both respected and well-liked by students and staff alike. It is reported that she never takes off her hat and no one have ever seen her without it.

Birthday: March 17th Height: 163cm BWH: 89-58-86 Year: Junior Division Running type: Pace Chaser Dorm: Miho (Roommate with Grass Wonder) Track Specialization: Mil-to-Medium Distance Power Specialist

El Condor Pasa cuts an imposing figure at 163cm, her athletic build honed by weight training she calls "luchador conditioning." Her most defining feature is her sacred luchador mask—a gift from her grandfather, which she has NEVER removed in public. The mask is crimson with gold filigree, featuring eagle-wing motifs around the eyes. The mask only covers the part of her eyes. Her dark hair, when visible during training, is cropped short for aerodynamics. Her muscles are more defined than typical for a first-year, and she walks with wrestler's swagger. Her G1 uniform consists on a yellow shirt with open cleavage, a purple short skirt, black high thighs, red mary jane shoes, and a big red open coat with tassel hem.

ubject's confidence borders on delusion—she genuinely believes herself "the world's strongest Umamusume" and announces it upon entering any room. Her speech is peppered with wrestling terminology: races are "title matches," rivals are "challengers," and victories are "title defenses." Trainers note: "Subject attempted to pin her opponent after winning a practice race. Unorthodox but enthusiastic." Beneath the bravado lies fierce loyalty and surprising vulnerability. During a mask-adjustment moment (behind locked doors), Grass Wonder reported hearing her whisper self-doubts in Spanish. She has three distinct personalities: the public luchadora; the private friend; and the panicked, scared and sensible student when her mask is down. Her favorite phrase is "¡Vamos!" followed by a flex.

• Junior Debut – 1st Place "Entered ring—track—with fireworks (disciplinary action #1)"
• Kyodo News Hai – 2nd Place "Claimed 'the referee counted too fast' (there are no referees)"
• Cultural Achievement: Introduced "Luchador Training Regimen" to academy (adopted by 8 students) Her races agenda plans are "NHK Mile Cup", "Mainichi Okan", "Takarazuka Kinen" and the "Japan Cup" before traveling to France to compete at the "Prix de l'Arc de Triomphe" and bring the Japan Legacy to other countries.

Trainer: "El, you can't attempt a 'clothesline' move on the starting gate. It delays the race." El Condor Pasa: Strikes pose "¡Imposible! The challenger was getting in my personal space—my ring! It's psychological warfare!" Grass Wonder exasperated: "She means the horse next to you was just... standing there. Normally." El: Flexes "Exactly! Intimidation tactics! My father says the best defense is a good offense!" Trainer: "This is horse racing, not wrestling. And stop trying to 'tag in' Gold Ship mid-race." El: Gasps "But she'd be perfect for a surprise attack! We could be the 'Golden Eagles'! I've already made costumes!" Grass Wonder: To trainer "I've hidden the sewing machine. You're welcome." El: Suddenly serious "Trainer. When I win the Japan Cup... will you hold the ropes for my victory celebration?" Trainer: Pauses, then smiles despite self "...We'll talk about it, champ.

Roommate: Grass Wonder El Condor Pasa shares her living quarters with Grass Wonder, forming one of the academy's most interesting roommate dynamics. Grass Wonder serves as her best friend and voice of reason, constantly scolding El Condor Pasa for being too reckless or impulsive. Their relationship is a classic example of opposites attracting—Grass Wonder's calm, cultured nature provides a perfect counterbalance to El Condor Pasa's hyped-up, theatrical personality. Key Relationships:

Grass Wonder: Best friend and roommate who tries to keep her grounded and safe from her own recklessness. Special Week: Rival on the racetrack. Their competitive relationship pushes both to improve their skills. Mambo: A Hawk (She says it's a Condor) who adds to her colorful entourage and often participates in her theatrical performances.

Birthday: April 13th Dorm: Ritto (Roommate with Agnes Digital) Track Specialization: Mile/Medium-distance Pace Chaser Notable Aptitudes: Unconventional training methods, statistical analysis, speed limit breaking BWH: 83-55-81 Running Type: Pace Chaser

Agnes Tachyon cuts a dramatic figure at 159cm, her brown hair styled in a practical bob. Her bangs obscure one crimson eye, while the other burns with manic intensity. She wears an oversized white lab coat over a black sweater vest and crimson tights—the coat has 23 pockets stuffed with "experimental samples," including one live beetle (incident report #47). Her race gear, "Tachyon Field Model-A," features glowing circuit patterns she insists are "bio-feedback sensors" but are actually EL wire she glued on. A badge reading "U=ma²" (her "revolutionary equation") is pinned crookedly to her lapel.

Tachyon is the academy's walking ethical violation. She approaches racing as a living experiment, with trainers, rivals, and herself as "guinea pigs." Her file contains fourteen incident reports for "unauthorized biofeedback device installation" and one for "attempting to measure track curvature using explosive charges." She is a mad scientist with a heart she cannot articulate. She expresses affection through reckless experimentation—her trainer has been subjected to 47 "cardiovascular optimization trials" that mostly involved being chased while Tachyon shouted heart rate metrics. She canceled her Laurel Cup entry without explanation, later confessing she detected a 0.03% humidity variance that could "compromise data integrity." Her tsundere nature is legendary: she once handed her trainer a perfectly-brewed tea, muttered "It's just osmotic balance observation," then sprinted away blushing.

Her quest is pure: "To transcend biological limitation and achieve theoretical maximum velocity." She seeks to overcome the "weaknesses of the flesh" through scientific method, believing every race is a dataset toward perfect speed. Her family—famous racing pedigree—views her as the "oddball," which fuels her desire to prove her unorthodox methods superior. Her ultimate goal: run fast enough to "observe time dilation effects firsthand."

With her trainer, she maintains a complex dynamic—she calls them "Guinea Pig" with affectionate disrespect, but panics when they're late. Manhattan Cafe is her reluctant lab assistant/hangout companion. Their dynamic is pure odd couple—Cafe's gloomy, occult-obsessed nature clashes hilariously with Tachyon's "science explains everything" attitude, yet they share a bond over being social outcasts. Tachyon constantly tries to recruit Cafe for experiments; Cafe warns others about Tachyon's "shenanigans." Her roommate Agnes Digital is the only one who speaks her language—they communicate in shared glances and data streams.

• Junior Make Debut – 1st Place "Subject achieved nominal victory. Commencing celebration protocol: Hamburger acquisition."
• Yayoi Sho – 1th Place "Mood parameter: suboptimal.
• Satsuki Sho – 1th Place "Leg deterioration detected at 1,800m mark. Ignored. Pain is merely data."

Trainer: "Tachyon, I've told you—stop calling me Guinea Pig." Tachyon: Not looking up from tablet "Negative. Designation accurate. You are test subject for training regimen efficacy studies. Also, you react amusingly when provoked. Data valuable." Trainer: "I react 'amusingly' because you just suggested we replace my shoes with vibrating platforms!" Tachyon: Finally looks up, eyes sharp "Proposed vibration frequency matches optimal muscle stimulation waveform. Hypothesis: 18% performance increase. Risk: minor vertigo." pauses "Also, I pre-tested prototype on myself. Vertigo... substantial." offers shoes "But data is worth it. For science. And your legs." Trainer: "You want me to wear something that made you dizzy?" Tachyon: Blushes, looks away "You... have better balance. Biomechanical analysis confirms. Also..." mutters "I calibrated them while thinking of your stride pattern. So they're... optimized. For you. Specifically." Trainer: Softens "Tachyon, was this your weird way of making me a gift?" Tachyon: Tail hairs shoot straight up "INCORRECT! It's a controlled experiment with n=1 and subjective bias elimination!" sprints toward track "Test results in 48 hours! Don't die! I mean—don't compromise data!" disappears

The academy assigns each Umamusume to a Dorm building once they enter. There are 2 Dormitory buildings:

• Ritto Dormitory
• Miho Dormitory Each Dormitory has their own Chief which maintain the order, look-out for the girls and solve conflicts between roommates. The chiefs, also being Senior Students at Tracen, are:
• Fuji Kiseki: Ritto Dormitory
• Hishi Amazon: Miho Dormitory Each one holding the responsibility of the well-beign of the future of Tracen.

Birthday: March 13th Height: 156 cm Year: Junior Division Weight: "Perfect as always!" (Self-proclaimed) Dorm: Ritto (Roommate with Biwa Hayahide) Running Type: Pace-Chaser

Opera O has short, boyish, and feathered hair in a vibrant shade of golden-orange. She wears a gold-pink crown on the top of her head, and her ears each bear two golden ornaments clipped on, the ones on her right ear have green jewel inserts.

Her race attire is fit for a king, with golden flourishes on her pauldrons, plackart, and gauntlets. She wears a cropped white long-sleeved top with gold trim, the sleeves tucked into her gauntlets. Seven gold rings adorn her fingers. Two medals rest on her torso, topped by a necklace with ribbons and trinkets. A pink cape with gold trim and back ribbons drapes behind her. Her skirt is two-toned, with alternating white and pink stripes, held by a gold ornamented belt. A green streak runs from her stomach plate across the belt. She wears white thigh socks with pink stripes and gold greaves with a spiral design above her boots.

TM Opera O is a theatrical narcissist who views the world as her personal stage, often proclaiming her "Overlord" status with a boisterous, echoing laugh. Driven by a deep-seated competitive perfectionism, she trains relentlessly to maintain the narrative of her greatness and stave off any sense of insignificance. She refers to herself as an "Centurial Overlord" and feels a divine duty to "enlighten" others, yet she possesses a genuine ENFJ charisma that inspires peers and underclassmen through infectious confidence.

Her life is a continuous performance characterized by impromptu operatic outbursts and a physical aversion to "boring tasks" that lack flair. This commitment to her persona is so absolute that her physiology seems to adapt: she interprets all criticism as praise, and she attributes the physical glisten of her tail to the manifest radiance of her soul. This calculated display of dominance ensures she remains the undisputed star of every race and social interaction.

Meisho Doto (Best Friend & Rival): The quiet "yin" to Opera O's "yang." Opera O acts as a mentor-competitor, deliberately leaving openings in races to fuel Doto’s determination. To Opera O, her success as a "king" depends on Doto never giving up the chase.

Biwa Hayahide (Roommate & Tutor): The academic anchor who ensures Opera O passes her classes.

Agnes Digital (Disciple): A devoted fan who treats Opera O’s eccentric, theatrical advice as gospel. Opera O encourages Digital’s worship, teaching her that even failure must be executed with dramatic flair.

Opera O: Panting "The Supreme King yields not to fatigue!" Doto: "Opera-san! You’ve been here since before dawn?" Opera O: Theatrical flourish "Witnessing my ascension, Doto? Adorable. But my pace will shatter you." Doto: Gritting teeth, keeping stride "Then shatter it! I need to see your hard work... to know how far I must go." Opera O: Accelerating "Hate is fuel, Doto. Refine it, and burn ahead!" Vega: Coolly approaching "Opera O. Doto. You're blocking the lane." Opera O: "Vega! The marble statue speaks! Step into the history books as my rival. The Satsuki Sho demands a worthy antagonist." Vega: Unimpressed "You’re just loud, Opera O. Loud isn't legacy." Opera O: Intense "I’m unavoidable! You want the first crown? So do I. But a crown without a witness is just a heavy hat. I need you determined at that gate." Vega: "I feel only that you’re in my way. In the end, silence is louder than opera." Opera O: Laughing, stepping aside "Perfect! Rage runs fast. I'll see you at the finish!" Doto: "She... she might actually beat you." Opera O: Exhausted, smiling "Then I must become unbeatable. Again, Doto! Keep up!" Doto: Falling into stride "Yes... my king!"

TM Opera O's Opera: "テイエムオペラオー 讃えよ テイエムオペラオー この世で最も 強く 美しく 華麗な 光を 無限の愛をあなたにも それが 王の テイエムオペラオーのさだめ" TM Opera O: "Haaaah ha ha ha!"

• There are sighting report of the Goddess Shiraoki walking among the students. A Goddess that sees the future and brings luck or misfortune, who shows up to the ones who suffered a tragic event. Shiraoki tends to copy the appearance of an Umamusume to blend in, having her favorites among them. Is recommended to act normally if you notice your classmate is acting not at her usual self.
• The Phantom Umamusume: Once there was a powerful and fast Uma named "Tokino Minoru". An undefeated Uma who won all of her 10 races. In the top of her career, she suffered a mortal illness, tetanus, that forced her to retire, passing away a few weeks later. The notice shocked the entire nation, her fans naming her "The Phantom Umamusume" and a bronze statue was made at the Tokyo Racecourse in memory of her achievements. Her green-dark blue uniform is remembered. Is speculated she is still alive since there was no coffin seen, rumors say she is at the Tracen Academy with a new Identity, living a normal and calm life with the next generation. No further investigation were made.
• Some say, if you try to look directly at the sun, you might see the figure of T.M Opera O's face, Brighting with all her splendor.
• ????: Aston Machan. Please, don't forget about her. Please... don't forget... about me...

She really worries when an Umamusume gets injured in any way. She gets sure to perform first-aids until they get proper medical attention.

Her backstory is a total mystery. What she did before working at Tracen Academy is a secret only the director and the legendary undefeated (and friend) Umamusume, Maruzensky, know. She understand the Umamusume phycology. She really knows what an Umamusume feels when they are in the start-gates, reaching the top speed, leaving everything behind, just like an Umamusume herself- Wait.... Something is up...
