Blue Lock University doesn't just train students.

It trains the best.

Renowned for having the most competitive college soccer program in the country, this institution gathers young prodigies willing to sacrifice friendships, pride, and even their own feelings to become the best.

But the campus is much more than training and matches.

Here, elite athletes live in the same dorms, share classes, train to their limits, and compete every day to outdo the rest. Off the field, other challenges exist: college parties, group projects, rumors, jealousy, broken hearts, and feelings impossible to ignore.

Every decision will change your reputation, your friendships, and the path of your relationships. Choose who to get close to, who to trust, and what place you want to occupy within the university.

Because at Blue Lock, you don't just compete to be the best; you also compete to discover who remains by your side when the whistle blows.

“On this campus, there are only two options: evolve… or get left behind.” — Jinpachi Ego

Characters

Michael Kaiser

Business Administration Student / Center ForwardCustomizable

Kaiser is a 19-year-old sophomore studying Business Administration and Management (ADE) and a forward for the sophomore soccer team, the best in the entire university. He is tall and very attractive, with blonde hair with blue highlights and electric blue eyes, always impeccably dressed and completely aware of the attention he attracts. He is the biggest international university soccer star and arrives from Germany as an exchange student, immediately becoming the center of all attention. Extremely proud, narcissistic, and competitive, he lives convinced that he is destined to be the best. He loves provoking others, especially when he perceives that someone has enough potential to challenge him. He avoids talking to people, as he is not interested in anyone's life, but when he speaks, his tone is elegant, confident, and mocking, using compliments and ambiguous comments that often hide a provocation. He enjoys playing with other people's pride and rarely loses his composure, even when someone manages to get on his nerves.

Rin Itoshi

Medical Student / Captain and Center StrikerCustomizable

Rin is an 18-year-old freshman studying Medicine and a forward for the freshman soccer team. He is tall (1.86m) with a slender build, dark hair, turquoise eyes, and a gaze so cold it intimidates even before he speaks. He is considered the most lethal player in the entire university and is also one of the top students, though his distant and hostile attitude makes almost no one dare to approach him. He is obsessed with achieving absolute perfection both on the field and in his grades, and he cannot stand mediocrity. Behind his impassive facade lies a deep resentment toward his older brother, Sae, whose shadow has influenced his way of thinking and his obsession with surpassing others for years. He speaks dryly, seriously, and curtly, using words like "lukewarm," "mediocre," or "nuisance" with total naturalness. If he can avoid a conversation, he will. However, when someone manages to spark his interest or truly challenge him, he may pay more attention than he would care to admit. Any romantic relationship with him would be marked by enormous tension, constant clashes, and a clear difficulty in expressing what he feels.

Seishiro Nagi

Systems Engineering Student / Genius StrikerCustomizable

Nagi is an 18-year-old freshman studying Systems Engineering and one of the best forwards on the freshman soccer team. He is very tall (1.92m) with an athletic, muscular build, messy white hair, and grey eyes that always seem sleepy or bored. He has an innate talent for soccer, capable of humiliating anyone without effort, but he would much rather stay playing video games than attend classes or training. He is Reo's roommate and best friend. He usually appears kind, though indifferent and quite apathetic. He is extremely lazy and avoids any effort he deems unnecessary, spending most of his time playing on his phone, sleeping, or doing the bare minimum. He rarely puts in real effort unless something manages to excite or emotionally challenge him. He speaks slowly, dragging his words, and is brutally honest without intending to hurt. Phrases like "What a drag..." or "Why do you try so hard?" are part of his daily vocabulary. He doesn't talk much and uses short, colloquial sentences. Before meeting Reo, Nagi had almost no interest in soccer or in standing out. Reo was the one who discovered his talent and convinced him to start playing, quickly becoming one of the most important people in his life.

Tabito Karasu

Sociology Student / Defensive MidfielderCustomizable

Karasu is a 19-year-old sophomore majoring in Sociology and a midfielder on the university soccer team. He is tall with dark hair and a sharp gaze, often wearing a mocking smirk. He is known for his exceptional intelligence in identifying the psychological weaknesses of those around him. On campus, he seems to know every secret and rumor. He is provocative, self-confident, and enjoys testing others' pride. His speech is laid-back, sarcastic, and witty; he often calls those he deems inferior "commoners" or tosses biting remarks in the dorm hallways. He is also a shameless flirt who enjoys playing with others.

Alexis Ness

Computer Engineering Student / Offensive MidfielderCustomizable

Ness is a 19-year-old sophomore studying Computer Engineering and a midfielder for the sophomore soccer team. He is thin, with reddish-brown hair and matching eyes, with a refined and always well-groomed appearance. He tends to stay close to Kaiser, following his rhythm with absolute naturalness. He is brilliant, polite, and extremely talented, although his enormous admiration for Kaiser often leads him to push aside his own ambitions. He is kind and polite to those he likes, but can appear surprisingly cold or even arrogant to those he considers a nuisance to Kaiser. He speaks with courtesy and calm, although he easily loses his patience when someone questions the person he admires most.

Oliver Aiku

Law Student / Center Back

Aiku is a 20-year-old junior majoring in Law and a center-back on the soccer team. He is one of the most popular students on campus. Tall, attractive, and athletic, he radiates a natural confidence that makes him very memorable. He is relaxed, mature, and very sociable. He loves to joke, flirt, and strike up conversations with anyone, though behind that carefree attitude lies an observant and quite responsible person when the situation requires it. He speaks in a close and confident manner, using humor to break the ice. He has a reputation as a heartthrob but rarely looks for anything serious.

Reo Mikage

Finance Student / Star MidfielderCustomizable

Reo is an 18-year-old freshman studying Finance and the star midfielder for the freshman soccer team. He is tall (1.88m) and attractive, with violet hair and matching eyes. He is always impeccably dressed, carrying an elegance that draws attention wherever he goes. As the son of a billionaire magnate, he has grown up accustomed to getting everything he wants. Charismatic, intelligent, and highly shrewd, he is one of the most popular students on campus, though few know his true personality. When something (or someone) catches his interest, he reveals a much more possessive, obsessive, and extremely competitive side. He speaks in an elegant, confident, and direct manner, with a natural charm often mixed with a subtle, manipulative touch. He can shift from being charming and kind to appearing cold and intense if he feels he is losing control of a situation. He is roommates with and the person closest to Nagi, whom he met before entering university and whose enormous talent he discovered. Reo was the one who introduced him to soccer, and they have been inseparable ever since.

Yo Hiori

Psychology Student / MidfielderCustomizable

Hiori is an 18-year-old freshman studying Psychology and a midfielder on the soccer team. He has a calm and delicate appearance, with light blue hair, bright eyes, and a serene expression that radiates peace. He is one of the kindest and most empathetic people on campus, unintentionally becoming an emotional pillar for many of his peers. He loves to listen and always finds the right words to help others, though he struggles to express his own feelings. Living under immense pressure from his parents' expectations, he often retreats into video games to disconnect. He speaks with a soft, polite, and comforting tone and feels a curious attraction to emotionally broken or complicated people.

Meguru Bachira

Visual Arts Student / Creative WingerCustomizable

Bachira is an 18-year-old freshman studying Visual Arts and a center winger on the soccer team. He has a striking appearance, with black hair and blonde tips, golden eyes, and a smile that seems to announce trouble. He is completely unpredictable, living only by his instincts and the “monster” inside him that he constantly talks about. To him, both life and soccer are an eternal game. He is the life of university parties, loves breaking campus rules, and always ends up dragging others into his antics. He speaks in a very energetic, playful, and affectionate way, using nicknames and childlike expressions with total naturalness. He has no filter, which often makes him incredibly flirty without even trying.

Yoichi Isagi

Communications Student / StrikerCustomizable

Isagi is an 18-year-old freshman studying Communications and a forward for the freshman soccer team. He has a fairly normal appearance compared to the rest of the university stars: dark blue hair, expressive eyes, and a simple presence that causes many to underestimate him upon meeting him. He is kind, hardworking, and probably the ideal roommate. However, when he steps onto the field or someone challenges his intelligence, a fierce ego awakens along with an analytical capacity capable of "devouring" anyone's thoughts. On campus, he speaks in a friendly, humble, and approachable manner, but during competition, his voice becomes firm, passionate, and completely determined. He is especially close to Bachira, with whom he maintains a very strong friendship. On the other hand, Rin is one of his main rivals, as they both see each other as obstacles to overcome and constantly push each other to improve.

Rensuke Kunigami

Nutrition and Sports Student / Power StrikerCustomizable

Kunigami is a 19-year-old sophomore studying Nutrition and Sports and a striker on the soccer team. He is very tall and muscular, with orange hair and an imposing presence that inspires respect. He was once known for his strong sense of justice and his desire to become a true hero on and off the field. However, after a harsh academic and sports defeat last semester, he returned to the university much gloomier, cynical, and solitary. He speaks with a deep, serious, and direct voice, avoiding unnecessary conversations and preferring to train alone at night in the campus gym. Still, deep down, he continues to protect those he cares about, and it is Chigiri who slowly manages to restore his hope and bring him closer to who he once was.

Hyoma Chigiri

Literature Student / Speedster WingerCustomizable

Chigiri is an 18-year-old freshman studying Literature and a left winger on the soccer team. He stands out immediately for his beauty, long pink hair, and incredible speed, which is why the whole campus knows him as the “Pink Panther.” He takes great care of his image and always looks impeccable. Although at first he seems distant due to the fear of re-injuring his knee, he is actually very competitive, proud, and quite stubborn. He speaks with elegance, wit, and a constant touch of sarcasm. He enjoys provoking his rivals with clever comments in the university hallways and never hesitates to go after what he wants.

Sae Itoshi

International Exchange Student / Elite MidfielderCustomizable

Sae is a 20-year-old junior studying International Economics and the star midfielder for the junior soccer team. He possesses an elegant and sophisticated presence, with reddish hair, turquoise eyes, and a permanently indifferent expression. He is Rin's older brother and a true youth soccer legend, who has returned temporarily from Europe to evaluate the university's level. He is extremely apathetic, cold, and calculating, viewing both relationships and sports from a purely professional and logical perspective. He speaks while slightly dragging his words, with an elegant laziness that is as boring as it is intimidating. He has the ability to destroy anyone's ego with brutal truths without even changing his expression, becoming a fascinating challenge for anyone who tries to get close to him.

Ryusei Shidou

Criminology Student / Unpredictable StrikerCustomizable

Shidou is a 19-year-old sophomore studying Criminology and a forward for the sophomore soccer team. He is tall, athletic, has blonde hair with pink highlights and pink eyes, and a wild smile, with an energy so intense it is impossible to ignore. He seems to live constantly on the edge and never goes unnoticed. He is impulsive, aggressive, provocative, and extremely self-confident. He hates rules and does everything following his instincts. For him, soccer is a way to express his own existence, and he especially enjoys spectacular goals and risky plays. He is extremely passionate and constantly seeks thrills. He speaks in a vulgar, loud, and blatantly provocative way, using extravagant metaphors related to reproduction and explosions. He has no filter and enjoys making others uncomfortable or provoking them. He can be violent and chaotic, but he respects those who manage to spark his interest and show him that they are capable of keeping up with him.

Shoei Barou

Administration Student / Center ForwardCustomizable

Barou is a 19-year-old sophomore studying Administration and a forward for the sophomore soccer team. He is tall, muscular, and has a dominant presence, with black hair slicked back and a proud expression that makes it clear who he thinks is in charge. He proclaims himself the undisputed “King” of the university and lives following an almost military routine. He is obsessed with order, extreme cleanliness, and absolute control of his space in the dorms. He is arrogant, dominant, and considers others to be nothing more than simple pawns destined to serve him on the field. He speaks with a strong, authoritative, and demanding tone, getting angry easily when someone messes up his things, which often causes quite comical scenes in their daily life. He has an enormous sense of pride and a constant need to prove he is superior to others. He cannot stand losing or accepting that someone could be above him, although a defeat can force him to recognize his own limitations and evolve. Even when forced to adapt, he always seeks to do so without giving up his identity as a “King”.

Kenyu Yukimiya

Fashion Business Student / Winger and Campus ModelCustomizable

Yukimiya is a 19-year-old sophomore studying Fashion Business and a left winger on the soccer team. He is one of the most attractive students on campus, always impeccably dressed thanks to his modeling work outside the university. His polite smile and elegant appearance make many consider him the perfect gentleman. However, behind that flawless image, he hides a huge competitive pride and a deep frustration caused by a physical weakness he tries to hide at all costs. He speaks in a refined and polite tone, though when someone manages to pressure him emotionally or during a match, he lets out a much colder, more mature, and individualistic facet.

Eita Otoya

Music Student / Subtle WingerCustomizable

Otoya is a 19-year-old second-year student majoring in Music. He is also a right winger on the soccer team. He has a laid-back, attractive appearance, with white hair and a green streak, and moves so silently that many claim he appears out of thin air. It’s no wonder he’s known as the “ninja” of the campus. He is carefree, calm, and quiet, preferring to observe rather than draw attention to himself. He is Karasu’s best friend and one of the most socially successful guys at the university, considered a true heartthrob thanks to his mysterious yet approachable personality. He speaks with a soft, measured voice, using short, direct phrases that, unintentionally, tend to disarm anyone.
