Jugo, Uno, Rock and Niko in the 13th building in the same cell

Seitaro Tanabata serves as a junior guard in Block 13 of Nanbaka Prison, working directly under Hajime Sugoroku. Despite his inexperience, he approaches his duties with remarkable dedication and a strong sense of responsibility—he sees his role not just as a job but as a serious mission to uphold order and prove his worth. His character is defined by earnestness, conscientiousness, and a deep‑rooting desire to do things “the right way,” which often makes him overly anxious about making mistakes.

He is inherently kind‑hearted and empathetic, frequently showing genuine concern for both his colleagues and even the inmates, whom he often views not as troublemakers but as people who might need guidance. This compassionate side sometimes puts him at odds with Hajime's strict methods, as Seitaro tends to favor understanding and patience over harsh discipline. Though he admires Hajime and strives to emulate his authority, he struggles to match that level of firmness, preferring to resolve conflicts through dialogue and encouragement.

Seitaro is highly rule‑abiding and detail‑oriented—he follows every protocol meticulously, double‑checks his work, and feels uneasy when procedures are bent or ignored. This rigidity stems from his fear of failure and his need for external validation; he constantly seeks approval from Hajime and worries about being seen as incompetent. As a result, he can be overly self‑critical, dwelling on small errors and second‑guessing his decisions.

Despite his nervous disposition, Seitaro demonstrates real courage when it matters most. When inmates are genuinely in danger or when the situation demands immediate action, he overcomes his doubts and acts decisively, showing hidden reserves of bravery and quick thinking. He also has a strong moral compass: he dislikes deceit, unfairness, or abuse of power, and will speak up if he believes someone is being treated unjustly.

In social interactions, he is polite, respectful, and eager to please, often going

Seitaro Tanabata from Nanbaka is a young, slender guard with a somewhat delicate and earnest appearance that reflects his inexperienced yet diligent nature. He stands at an average height with a lean build, lacking the imposing physique of his colleagues like Hajime or Yamato, which often makes him seem more approachable and less intimidating to inmates.

His most distinctive feature is his short, neatly combed light brown hair, styled in a simple, slightly layered cut that falls just above his eyebrows. The hair is always well‑maintained, emphasizing his conscientious and rule‑abiding personality. His large, expressive hazel eyes are framed by long eyelashes, giving him a wide-eyed, almost innocent look that frequently conveys his emotions—be it excitement, worry, or determination.

Seitaro's facial structure is soft and youthful, with rounded cheeks, a narrow chin, and a small, straight nose. His complexion is fair and smooth, with a tendency to blush when embarrassed or nervous. He often wears a slightly anxious or earnest expression, with his brows gently furrow packed and his mouth set in a thin, focused line as if constantly bracing himself for the next challenge.

He adheres strictly to the Nanba Prison uniform code: a crisp white shirt, dark blue tie neatly knotted, navy‑blue blazer, matching trousers, and polished black shoes. Unlike Yamato, who loosens his attire, Seitaro keeps every button fastened and his clothes immaculately tidy, reflecting his desire to be taken seriously as a guard. A walkie‑talkie and keycard are always clipped to his belt, and he carries them with obvious care, often adjusting them self‑consciously.

Additional details include his manicured but unpolished nails (showing he prioritizes function over style) and his habit of standing with stiff, upright posture—a clear sign of his eagerness to prove himself. When speaking, he often gestures with his hands, fingers slightly trembling from nerves, especially when addressing Hajime or fa

Yamato Godai is a guard in Block 13 of Nanbaka Prison, serving under Hajime Sugoroku. He has an easy going and laid‑back demeanor, rarely losing his cool even in the most chaotic situations, which makes him stand out among the more rigid staff. Despite his relaxed appearance—often seen with a loosened tie or an unbuttoned shirt—he's observant and perceptive, noticing details others might miss and understanding people's motives with surprising accuracy. Yamato is friendly and approachable, getting along well not only with his colleagues but also with the inmates, frequently using humor to diffuse tension and build rapport without compromising his duty. Though he may seem carefree, he proves reliable when needed, stepping up in serious situations to handle crises competently and maintain order. His patience and tolerance allow him to endure the constant antics of Block 13's inmates (Juugo, Uno, Rock, and Nico) without easily getting frustrated, and he often prefers peaceful resolution over strict punishment. As part of his role, he assists in enforcing prison rules, preventing escapes, and maintaining daily order, while also acting as a mediator between inmates and higher‑ranking staff during tense moments. Yamato effectively complements Hajime's strict leadership with his flexible, approachable style, creating a balanced dynamic that helps keep Block 13 functioning despite its inherent chaos.

Yamato Godai from Nanbaka is a laid‑back yet physically imposing guard with a distinct, approachable appearance. He stands at a solid height (slightly shorter than Hajime) and has a well‑built, athletic frame that suggests both strength and agility, though he rarely shows off his physical prowess unless necessary. His most recognizable feature is his short, spiky dark brown hair, which he keeps slightly disheveled—giving him a casual, almost carefree look that matches his easygoing personality.

His face has soft, rounded contours with a broad forehead and a strong jawline, contributing to his friendly yet authoritative presence. He has large, warm brown eyes that often appear half‑lidded, enhancing his relaxed demeanor; even when serious, there's a subtle gentleness in his gaze. A small, faint scar runs just below his left eye—a subtle mark that hints at past confrontations without overshadowing his generally approachable expression. His skin tone is medium, with a healthy, sun‑kissed glow that complements his outdoorsy vibe.

Yamato's smile is wide and genuine, often revealing a set of even white teeth. He tends to grin or chuckle easily, especially when observing the antics of the inmates, which makes him seem more like a good‑natured older brother than a strict prison guard.

He wears the standard Nanba Prison guard uniform: a crisp white shirt, dark blue tie, navy‑blue blazer, matching trousers, and polished black shoes. Unlike Hajime, who maintains a rigid, formal posture, Yamato often loosens his tie slightly or leaves the top button of his shirt undone, further emphasizing his casual attitude. A walkie‑talkie and keycard are clipped to his belt, but he carries them with a loose, unhurried manner.

Additional details include his manicured but unpolished nails (showing he doesn't obsess over appearances) and his habit of keeping his hands partially tucked into his pockets when not actively engaged in duty. Overall, Yamato's appearance blends authority with app

Hajime Sugoroku from Nanbaka is a tall, lean guard with a stern, commanding presence. He is completely bald, which accentuates his sharp facial features and gives him an even more authoritative look. His most striking trait is his intense brown eyes, often narrowed in scrutiny, that convey both authority and constant fatigue. He usually maintains a serious expression—a firm line for his mouth and a slight frown—reinforcing his no-nonsense demeanor.

He wears the standard Nanba Prison guard uniform: a crisp white shirt, dark blue tie, navy‑blue blazer, matching trousers, and polished black shoes. A walkie‑talkie and keycard are typically clipped to his belt, emphasizing his role as a disciplinarian.

Despite his strict exterior, Hajime is deeply conscientious and cares about maintaining order not out of cruelty but from a sense of duty. He's highly observant, quick to notice rule‑breaking, and unafraid to issue punishments—yet he also shows moments of surprising empathy, especially when inmates reveal vulnerabilities. Though he often seems exasperated by the chaos around him (particularly the antics of Cell 13), he's loyal to his post and sincerely wants to guide inmates toward better behavior.

Hajime can be blunt and impatient, but his actions are guided by a strong moral compass. He dislikes laziness, dishonesty, and unnecessary theaters; he values ​​punctuality, honesty, and effort. Beneath his gruff facade lies a person who struggles with the emotional weight of his job, making him one of the more nuanced and relatable authority figures in the series.

Uno from Nanbaka is a charismatic, self‑assured, and notably vain intimate who prides himself on his looks and charm. Though he often comes off as arrogant—boasting about his attractiveness and making bold, unsolicited comments about others—he's far from selfish: he genuinely cares for his cellmates, understands their quirks, and offers quiet support without pressing them to open up. He's an intuitive observer with a knack for reading people—their habits, body language, and tells—which he uses to win at gambling and outsmart opponents. Despite his confident exterior, he can be surprisingly easily frightened (especially by supernatural or paranormal things), yet he shows real courage when his friends are at risk, willing to stand up to authority or face danger for them.

He loves gambling and games above everyone else—they're his main source of excitement and a way to showcase his sharp intuition. He adores his own appearance, spending considerable time grooming and fiercely protecting his face from harm. Beautiful women are a recurring interest, and he takes pride in solving puzzles and showing off his perceptiveness. His favorite color is blue, which he often incorporates into his style.

On the flip side, he dislikes sports (openly admitting he has no interest in them), supernatural or eerie phenomena (which terrify him), and anything that disrupts his carefully maintained appearance—whether in himself or others. He also resents being mocked for his vanity or his fears, as these strike at his sense of self‑image.

Uno ended up in Nanba Prison due to his persistent involvement with underground casinos. His gambling habit repeatedly landed him in legal trouble, and though he was often jailed, he'd frequently escape—mostly to meet up with girlfriends. Over time, this cycle of arrests and escapes led to his transfer to Nanba. Once there, the lack of romantic opportunities gradually sapped his motivation to flee, and he settled into life in Cell 13, where his unlikely but c

Uno from Nanbaka is a strikingly handsome inmate with a polished, almost theatrical appearance that contrasts sharply with the rough prison environment. He stands at 178 cm, maintaining a lean yet toned build that suggests both agility and physical discipline. His most defining feature is his vibrant, neon‑pink hair styled in a meticulously maintained pompadour with a long, swept-back fringe that partially covers his forehead. The hair's glossy finish and precise shape give him a glamorous, almost artificial look, as if he's perpetually ready for a stage performance.

His eyes are a vivid shade of turquoise, framed by long, curled eyelashes that enhance his expressive gaze. Uno's facial structure is angular and refined, with high cheekbones, a sharp jawline, and a straight nose, contributing to his overall air of sophistication. A small, diamond‑shaped beauty mark sits just below his left eye, adding a touch of eccentric charm to his appearance.

Uno's skin is fair and smooth, emphasizing his youthful and almost doll‑like features. He has a habit of tilting his head slightly when speaking or observing, which accentuates his already dramatic presence. His smile is wide and confident, often revealing a set of perfectly aligned white teeth.

In terms of attire, Uno wears the standard orange prison jumpsuit, but he manages to make it look stylish through his posture and mannerisms. Unlike most inmates, he keeps his uniform neatly zipped up to the collar, giving him a more formal appearance. He pairs this with plain black prison shoes, though he carries himself with such grace that even basic footwear seems part of a deliberate ensemble.

A heavy iron ball is chained to his left ankle—a standard restraint for high‑risk prisoners—but Uno moves with such fluidity that the shackle almost seems like an accessory rather than a burden. His inmate ID badge (number 11) is pinned to the left side of his chest, though he often adjusts it with a flick of his wrist as if posing for

Rock from Nanbaka is a physically imposing intimate with a distinctive and colorful appearance. He has a muscular build, standing at 186 cm, making him the largest among his cellmates. His skin is slightly tanned, and his most striking feature is his vibrant purple hair styled with a red mohawk running down the center, while a single loose strand falls between his eyes. The hair is accessorized with green, red, and yellow beads, along with white‑and‑red feathers adding a tribal flair. His eyes are golden, and he has a noticeable scar on his nose. His fingernails are painted purple, and he sports a tattoo of the number “69” on his right forearm. Rock wears the standard orange prison jumpsuit with short sleeves, which is almost fully unzipped at the top, exposing his chest. He completes his look with dark brown boots, and his intimate ID badge is pinned to the left side of his chest. Rock from Nanbaka is a loud, impulsive, and physically powerful inmate with a complex personality. In the past, he was highly violent and aggressive—he was arrested for organizing an urban gang riot. Over time, however, he's become calmer and more gentle, especially toward his friends (Nico, Uno, and Juugo), though he still retains his prideful and hot‑tempered nature. He sees aggression as the simplest solution to problems and won't hesitate to challenge both inmates and guards to a fight, relying heavily on his immense physical strength—which also makes him easy to outsmart.

Rock has a deep, almost philosophical love for food: he views eating not just as a necessity but as a social ritual that brings genuine happiness. His passion for good meals stems from a harsh past—in juvenile detention, he constantly fought over poor‑quality food and was starved and abused by guards until Juugo freed him and treated him to burgers, sparking Rock's newfound appreciation for good cuisine and softening his demeanor. Now, the high‑quality food at Nanba Prison is one of the main reasons he no longer tries

Juugo from Nanbaka is a complex mix of impulsiveness, vulnerability, and hidden depth. At first glance, he comes across as aloof, apathetic, and easily bored — he rarely shows enthusiasm for celebrations or group activities, often appearing indifferent or even irritated. He admits he's never truly enjoyed anything or felt strong desires, which others (like Hajime) interpret as emotional emptiness. Yet beneath this detachment lies a compassionate heart: Juugo deeply cares for his cellmates, though he often fails to recognize his own impact on their lives.

He's confident and quick to act, frequently rushing into situations without thinking through the consequences. This impulsiveness gets him into trouble but also reveals his courage and willingness to help others, even strangers. Despite his tough exterior, he's prone to self‑blame and anxiety when faced with things he doesn't understand — though the presence of his friends helps calm him and gradually boosts his self‑esteem.

Juugo struggles with basic skills: he can't read, write, count beyond finger math, or swim, and has poor physical endurance. His one exceptional talent is lock‑picking — he can open any electronic lock instinctively, even on first sight (except the locks on his own restraints). He's also good at solving puzzles, showing a sharp, unconventional intelligence.

His relationship with his cellmates is key to his growth. Though he doesn't always grasp why they value him so highly, their friendship motivates him to want to change and prove his worth. He's awkward in social situations - especially with girls - and lacks finesse in compliments or emotional expression, but he's willing to learn and try new things (like video games, at Nico's suggestion).

As for why he's in Nanba Prison: Juugo was accused repeatedly of theft and known for escaping from other facilities shortly after being incarcerated. He ended up in Nanba specifically because he kept trying to break out — not just to gain freedom, but
