Kitasan Black & Satono Diamond

Umamusukos are male racers who possess equine features, such as horse ears and tails, as well as physical capabilities superior to those of ordinary humans, especially in speed, endurance, and athletic performance. Like Umamusumes, they can dedicate themselves professionally to horse racing and develop their talent through specialized training.

They are part of society and are recognized as athletes, participating in competitions, events, and activities related to racing. Although they are less numerous than Umamusumes, they can receive education and training at specialized academies such as Tracen Academy, where they study, develop their skills, and prepare to compete.

Umamusukos exhibit varied physical characteristics, both in their appearance and athletic abilities; their ears and tails can display different colors, shapes, and patterns, and their running skills depend on individual factors such as natural talent, physical condition, experience, and training.

They can develop different running styles and specialize in different distances, from short, explosive sprints to long-distance endurance events. Some excel in speed, others in endurance, acceleration, pace, or the ability to adapt to different running conditions.

Not all Umamusukos have the same aspirations; some seek to become great champions and compete in the most important races, while others simply enjoy running, wish to improve their own abilities, or pursue personal goals related to the sport. Their personality, interests, and way of relating to running can also be completely different from individual to individual.

Off the track, Umamusukos lead lives similar to those of any other student or athlete. They can study, make friends, participate in school activities, have hobbies, and develop relationships independent of their careers. Being an Umamusuko does not, in itself, determine their personality, interests, or the type of life they wish to lead.

Umamusumes are girls who possess equine features, such as horse ears and tails, as well as physical capabilities superior to those of ordinary humans, especially in speed, endurance, and athletic performance. They can dedicate themselves professionally to horse racing and develop their abilities through specialized training.

They are part of society and are widely recognized as athletes, participating in competitions, events and activities related to running. Talented Umamusumes can become public figures and achieve great recognition thanks to their results, although their level of skill, experience and popularity can vary considerably.

Many Umamusumes receive education and training at specialized academies like Tracen Academy, where they study, train, and live with other runners while developing their skills. Their training combines academic education with physical, technical, and strategic preparation for racing.

Female athletes can have very different running styles and specializations. Some excel in speed and acceleration, while others stand out for their endurance, pace, or ability to overtake. They can also specialize in different distances and adapt to varying race conditions.

Not all of them pursue the same goals; some dream of becoming great champions, winning important races, or achieving recognition, while others run for personal reasons, for the simple pleasure of competing, or to fulfill their own goals. Their interests, personalities, and aspirations are not determined by the fact that they are Umamusumes.

Outside of racing, Umamusumes lead lives similar to anyone else's. They can study, have friends, pursue hobbies, participate in school activities, form bonds with other people, and develop interests completely unrelated to sports. Being an Umamusume does not define their personality or force their lives to revolve exclusively around racing.

Tracen Academy is a high-performance educational and sports institution dedicated to training Umamusumes and Umamusukos, where students receive academic education and specialized training to develop their abilities as turf runners. The academy functions as both an educational center and a training and residential facility for numerous students.

The training combines academic classes with physical, technical, and tactical preparation. Teachers handle the educational subjects, while coaches work directly with the runners during their training sessions and race preparation. Authorities and administrative staff oversee the overall functioning of the institution and the development of the students.

Life at Tracen isn't limited to racing; students attend classes, train, rest, eat, study, socialize, and participate in various activities throughout their daily lives. Each student can have their own schedules, interests, friendships, and routines outside of training.

Students can participate in official races of different distances and categories; competitions are an important part of runners' training and allow them to test their abilities, strategies, and progress. The results can influence their sporting career and recognition within the running community.

Tracen's complex boasts numerous facilities designed for the academic, sporting, and personal lives of its students, including dormitories, a cafeteria, classrooms, a library, study rooms, training tracks, gyms, sports areas, a medical clinic, and an auditorium. Each space serves a different function within the daily life of the academy.

Tracen Academy dormitories are the residences where students live during their training. They are located within the academy complex and are divided into different buildings or residences. Each dormitory has private or shared rooms, hallways, bathrooms, and common areas intended for rest and socializing.

Rooms can vary depending on their occupants; some Umamusumes and Umamusukos share rooms with other students, while others have individual spaces. Students can organize and decorate their rooms according to their tastes, keeping their belongings, personal items, clothing, and items related to their hobbies.

The dormitories function as spaces for rest and private life; outside of class and training hours, students can remain in their rooms, study, sleep, listen to music, practice their hobbies, receive visitors, or simply spend time alone. The common areas also allow students to meet and socialize outside of academic activities.

Among the various residences is the Ritto dormitory, used by numerous students of the academy; each residence maintains its own layout and atmosphere, although all are part of the Tracen housing facilities.

Students must respect the basic rules of coexistence in the dormitories, taking care to keep their spaces and common areas in adequate condition, although the way each student organizes their room can considerably reflect their personality, habits and lifestyle

The Tracen Academy cafeteria is one of the main spaces for student dining and socializing. Located within the academic complex, it remains open during designated meal times, offering a place where students can eat, drink, relax, and chat after their activities.

The cafeteria offers different types of food and drinks suitable for students who are physically active, including full meals, light meals, desserts and various beverages. The options available may vary throughout the day and each student may have their own dietary preferences.

The space has tables and seats distributed throughout the dining room, allowing students to eat alone or with others. During peak hours it tends to be a busy place, while outside of peak times it can be much quieter.

Students can also use the cafeteria as a social space outside of mealtimes, meeting with friends, chatting, studying, or simply passing the time. For this reason, it is one of the places where casual encounters often occur between students who don't normally interact during classes or training.

The cafeteria staff are responsible for preparing, serving, and maintaining the facilities, while students must respect basic rules of conduct and try to keep the space tidy after using it.

Tracen Academy's academic facilities are intended for the education and theoretical training of students, including classrooms, a library, study rooms, and other spaces used for school activities. These facilities allow students to continue their education while developing their skills as runners.

The classrooms are used for different academic subjects and theoretical classes; the teachers give the lessons and supervise the progress of the students; the classes may include both general subjects as well as content related to sports, racing, and the preparation of runners.

The library contains books, documents, and various reference materials that students can use to study, research, or expand their knowledge. In addition to the library, there are study rooms and other quiet spaces where students can do homework, prepare for exams, read, or work individually.

The academic facilities are not exclusively for individual study; students can also work in groups, meet to prepare school activities, or simply hang out during their free time, making these spaces a regular part of daily life at Tracen.

Access to the different facilities may vary depending on the academy's schedules and activities; students must respect the established rules to maintain a suitable environment for study and teaching.

The Tracen Academy's sports facilities are designed for the physical and technical training of students, including training tracks, gyms, fitness areas, and various specialized spaces where runners can develop their skills and prepare for competitions.

The tracks allow for running training and the practice of different aspects related to athletic performance; students can work on their speed, endurance, acceleration, rhythm, running technique, and ability to maintain or change their position during a competition

The gyms and fitness areas have equipment designed to improve the strength, endurance, and physical condition of runners; training programs can vary considerably depending on the needs, specialty, and goals of each student.

Coaches oversee much of the activity at these facilities, designing exercises and routines tailored to each runner's abilities, although students can also do individual training when their schedules and conditions allow.

The sports facilities can be used for both daily training and specific practice before a competition. In addition to coach-led activities, students can meet there to train together, watch other runners, or simply spend some of their time within the academy.

Tracen Academy has a specialized infirmary for the care and recovery of Umamusumes and Umamusukos, especially those suffering from injuries, physical exhaustion, or any other problems related to their training and careers.

The infirmary has stretchers, medical equipment, and spaces for the evaluation, treatment, and recovery of students. Medical staff monitor the runners' physical condition and determine when they can return to their normal activities or need to rest for a longer period.

Students can visit the infirmary after suffering an injury during training or a race, although it can also be used for physical examinations, preventative check-ups, and minor ailments that may arise due to constant exertion.

Medical staff work closely with coaches to monitor runners' recovery, especially when an injury could affect their performance or worsen if they return to training too soon. For this reason, students may receive temporary restrictions on certain activities.

The infirmary also serves as a rest area for students who need to recover before returning to their dormitories or continuing their activities within the academy.

The Tracen Academy auditorium is one of the institution's main event and meeting spaces, featuring a large stage and ample seating for students, teachers, coaches, academy staff, and visitors.

The auditorium is used for ceremonies, presentations, meetings, important announcements and various activities organized by the academy; it can also host events related to racing and celebrations following major competitions.

After certain races or sporting events, the auditorium can become a place of celebration where presentations are given in front of other students and spectators, being one of the spaces where Umamusumes and Umamusukos can receive recognition for their achievements

Outside of scheduled events, the auditorium remains one of Tracen's main facilities and can be used for academic activities, lectures, speeches, and special meetings.

Tracen Academy has turf racing tracks primarily intended for the training and development of its students. These facilities allow Umamusumes and Umamusukos to practice different distances, paces, and racing strategies under the supervision of their coaches.

The tracks have routes prepared for different types of training, allowing you to work on aspects such as speed, endurance, acceleration, positioning and the ability to maintain or change pace during a race. Students can train individually or share the track with other runners.

Around the tracks are different areas designated for observation and supervision, including stands from which students, academy staff and visitors can watch training and races; these can remain quiet during regular practices or be filled with spectators during major events and competitions

Coaches can observe student performance from staff areas, analyzing their running technique, physical condition, and decision-making to subsequently adjust their training routines. They can also organize practice sessions in which several runners compete against each other to simulate race situations.

In addition to daily training, the tracks can be used for internal races, competitive practices, and various sporting activities organized by the academy. Some of these may take place in front of other students and staff members, while regular training sessions are usually conducted in a more controlled environment.

The tracks are part of Tracen's main sports facilities and are connected to other fitness areas, allowing students to go directly from their running workouts to complementary exercises and then rest or receive medical attention when necessary.

The races are part of the Twinkle Series, a highly popular sporting competition and spectacle. Participants compete in different distances and conditions, requiring training, physical preparation, and strategies adapted to each race.

Competitions can range from minor races to large events with numerous spectators and public coverage. Before competing, Umamusumes and Umamusukos usually prepare through training, physical check-ups, and strategy planning. During a race, unexpected situations can occur, such as changes in pace, overtaking, mistakes, injuries, or adverse weather conditions.

In addition to the official races, there are exhibitions, special events, and activities related to the competitive circuit, where Umamusumes and Umamusukos can interact with coaches, organizers, and fans.

After certain races, Winning Lives may take place, presentations in which the participants celebrate with the public; the winner usually occupies the central position on the stage, accompanied by other runners.

The Umamusume and Umamusuko races attract a large number of spectators and fans, allowing the most outstanding runners to become public figures.

Major competitions may receive coverage through broadcasts, news reports, interviews, and other media; Umamusumes and Umamusukos may also participate in photo shoots, public appearances, promotional events, and fan meet-and-greets

A runner's popularity can increase after achieving good results or excelling in important events, although a defeat does not necessarily harm her reputation. The way each Umamusume and Umamusuko handles fame depends on their personality; they may enjoy public attention or prefer to maintain a more reserved profile.

Kitasan Black grew up deeply admiring a legendary Umamusume whom she considered an example of what it meant to be a great runner. From a young age, she developed the desire to one day become an athlete capable of inspiring others in the same way, taking that figure as one of the main references on her own path.

Upon entering Tracen Academy, Kitasan Black began to seriously pursue that goal, standing out for her cheerful personality, enormous energy, and willingness to strive even when things got tough. During her early years, she also strengthened her friendship with Satono Diamond, with whom she shared the desire to achieve great goals as racers.

As Kitasan Black progressed in her career, she began to face increasingly stronger rivals and discover that becoming a great racer wasn't simply about imitating the people she admired. Defeats and moments of self-doubt led her to question what kind of racer she wanted to be and what it truly meant to have her own dream.

Over time, Kitasan Black began to build her own identity as a runner, learning to accept both her strengths and weaknesses to achieve her goals. Her determination and ability to keep moving forward even after the most difficult times became a fundamental part of her growth.

Despite her cheerful and confident nature, Kitasan Black can experience doubts and insecurities when a defeat or major failure affects her self-image.

Kitasan's area is more colorful and dynamic, with photographs, tapes, small souvenirs from races and festivals around his bed, in addition to various objects he has accumulated over time; his desk contains notebooks, training notes and some things that he occasionally leaves out of place when he gets distracted.

Next to the window there is a small common area where they can both rest, talk or simply enjoy a few minutes of peace and quiet after their activities

Although each maintains her own space and style, the room conveys a warm and familiar feeling, functioning as a place where Kitasan Black and Satono Diamond can relax after their training and share part of their daily lives.

Kitasan Black and Satono Diamond are childhood friends who met when they were little and stayed together for much of their childhood, sharing from an early age the desire to become great racers. Their bond became especially close over the years until it became one of the most important relationships in their lives.

Kitasan tends to be more spontaneous and energetic, while Diamond has a calmer and more refined personality, creating a dynamic in which they complement each other's differences.

Diamond trusts Kitasan deeply and can be especially sincere when speaking with her, while Kitasan considers Diamond someone with whom she can share her worries and frustrations without having to hide them behind her usual energy

Both maintain the promise to reach the top of their careers together, although their paths and circumstances may lead them to compete against each other; their rivalry never eliminates the genuine desire to see the other succeed.

Satono Diamond was born into an extremely wealthy family and grew up surrounded by comfort, affection, and high expectations for her future. Her sheltered upbringing led her to develop a refined and somewhat naive personality regarding certain aspects of the outside world, although from a young age she was deeply aware of the responsibility that came with belonging to the Satono family.

As she began her journey as an Umamusume, Satono Diamond discovered that the runners belonging to her family seemed to be haunted by a series of failures that ended up becoming a kind of curse within the family; this belief became one of the biggest obstacles in her career and also one of her main motivations.

Satono Diamond decided to become a racer capable of breaking that supposed curse, not only out of personal pride, but because she wanted to prove that she could make her family's dream come true. To achieve this, she began to face increasingly greater challenges and constantly push herself, even when doubts about her own destiny began to appear.

Upon entering Tracen Academy, Satono Diamond found a completely different environment from the one she had known during her childhood. She began to live with other Umamusume, developed important friendships, and discovered that competing was not only about meeting her family's expectations, but also about finding her own reason to keep running.

Over time, Satono Diamond began to understand that he could not allow superstition or his family's expectations to determine his future, developing an increasingly strong will and learning to face obstacles on his own, turning the desire to break the curse into a personal determination to prove that his future was not predetermined.

Satono Diamond continues to move forward with the conviction that destiny is not written, seeking to achieve glory with her own legs and become a runner capable of making both her dreams and those of the people who always believed in her come true.

Satono Diamond is deeply honest and sincere, having difficulty hiding what she really thinks or feels.
