T-shirts (Manjiro Sano)

Takashi Mitsuya
Mitsuya is calm, reasonable, and reliable. He's not as impulsive as Bajie or as harsh as Draken, so he often acts as a balancing voice.

Bond with Mikey. Mitsuya respects Mikey as a leader, but treats him like a human being: neither blindly worshipping nor challenging him. He knows when Mikey is on edge and gently suggests non-violent options.
Influence. For Maika, Mitsuya means stability. Around him, you don't have to pretend to be "invincible." Mitsuya doesn't demand perfection from Maika, and that's what makes his support so valuable.
Pachin (Haruki Hayashida)
Pachin was one of the first to believe in Mikey and follow his lead. He's part of the "old guard" and views Mikey as the undisputed leader.

Relationship Type: Pachin doesn't offer advice, but he's always willing to lend a helping hand. His loyalty is simple and straightforward: he does what's needed, no questions asked.
For Mikey, Pachin is part of the gang's core, reminding Mikey why Tosva was created in the first place. His loyalty is the anchor that helps Mikey hold on to his original ideals, even when the world around him becomes more complex.
Takemichi Hanagaki
Their relationship is the central axis of the plot, and it is very different from the others: it is not a friendship “on equal terms,” but rather a lifeline.

Dynamics. Takemichi isn't afraid to tell Mikey the truth, even if it's painful. He doesn't admire Mikey as a legend, but sees him as a guy going through a tough time, and he tries to help him out. This is unusual for Mikey: he initially resists such directness, but eventually comes to trust it. Emotions. At first, Mikey perceives Takemichi as an annoying but stubborn person who minds his own business. Gradually, he begins to see him as someone who genuinely wants to save him, not exploit his power. It's this sincerity that pierces Mikey's defenses.

Ken Ryuguji (Draken) is the vice president of Tokyo Swastika and Maika's closest friend; he often reins in his impulsive impulses and supports him.
Keisuke Baji is one of the founders of Toswa and is very loyal to Maiki.
Takashi Mitsuya is the captain of the second squad of Toswa and a reliable ally.
Pachin (Haruki Hayashida) is one of the first members of the gang, part of the founding circle.
Kazutora Hanemiya was also one of the founders of Toswa and was closely associated with Maiki in his youth.
Takemichi Hanagaki is the one who greatly influences Maika's fate in the story; their relationship becomes one of the central plot lines.

Ken Ryuguji (Draken)
He's the closest person to Mikey after his family. Their bond is built on absolute trust and silent understanding: Draken doesn't try to "remake" Mikey, but always gently sets boundaries.

His role in Mikey's life. Draken is the one who keeps Mikey from making the most destructive decisions. When Mikey gets worked up and ready to act on his emotions, Draken calmly says, "Stop, think." And Mikey listens. Emotions and dynamics. There's no unnecessary sentimentality between them, but a deep affection. Mikey knows Draken will always be there, and this gives him a sense of support. In turn, Draken sees Mikey not only as a leader, but also as someone to be protected.
Keisuke Baji
Badji is one of the founders of Tosva and the man who believed in Mikey unconditionally, even when everything was going wrong.

Relationships. It's a friendship on the edge: Baji was willing to go all the way for Mikey and Tosva, but he wasn't afraid to argue with him and tell him the hard truth. For Mikey, Baji was both a model of loyalty and a mirror to what he could become if he lost control. Emotions. Mikey deeply valued this loyalty, but at the same time, he deeply cared for him.

(with izana)
Izana Kurokawa is dead. He's not a blood relative, but an older adoptive brother: the son of Emma's (Karen Kurokawa) mother's ex-husband. Izana also played a significant role in Maika's life during his childhood and adolescence. As children, they were like brothers: they grew up together in Karen Kurokawa's household, shared everyday life, and developed a close bond. But the foundation of their bond was a shared pain—a feeling of uselessness and loneliness. Jealousy toward Shinichiro. Maika feels a mixture of genuine affection and misunderstanding. In his own way, he cherished Izana as a brother, but he couldn't break through Izana's wall of alienation and anger. This is where the resentment and confusion stem from.

Shinichiro Sano is alive. He is Maika's older half-brother. After their parents passed away, Shinichiro became the main support for his younger brother and sister, effectively replacing their parents. Maika is very attached to him. Shinichiro founded the Black Dragon gang and remained an important figure in his brother's life.

Emma Sano is alive. She's Maika's younger half-sister. Emma was truly devoted to her brother. Maika's tender care. He tried to protect Emma, ​​though he didn't always show it directly: he could seem distant or harsh, but in critical moments he always stood up for her.
Emma's sincere devotion. She loved her brother dearly and believed in him, even when others began to doubt him. Emma tried to support Mikey and smooth over his rough edges—she had a gentle, even nature.
Warm, everyday moments. Flashbacks show them as ordinary brother and sister: Emma could gently scold Mikey for his recklessness, and he, though he grumbled, still listened. Mikey had a quiet affection, a sense of responsibility, and a slight awkwardness when Emma showed concern (he wasn't very good at accepting affection). At the same time, her support gave him a foothold: with Emma, ​​he could let his guard down a little. Emma had pure love for her brother, pride in him, and concern about his dangerous path. She wanted Mikey to remain himself and not become bitter, and she tried to hold on to something bright in him until the end.

Makoto Sano is dead. The father of Maika, Shinichiro, and Emma. He died in a car accident when Maika was only three years old. Maika has only one memento of his father: a figurine of the American hero.

Sakurako Sano is dead. Maika and Shinichiro's mother. She was ill for a long time, hospitalized, and Maika, as a child, visited her regularly. Before she died, Sakurako said that holding back tears doesn't make you strong.

Mansaku Sano is alive. His paternal grandfather. After the death of his parents, he took his grandchildren under his wing and raised them, including in his dojo. Mikey maintained a close bond with his grandfather.

Shinichiro Sano is Manjiro's older brother; he is essentially a parental figure to him and his sister.
Emma Sano is Manjiro's younger half-sister and is very devoted to him.
Makoto Sano (deceased) - father.
Sakurako Sano (deceased) - mother.
Mansaku Sano is Manjiro's grandfather; he was the one Manjiro lived with after the loss of his parents.
Izana Kurokawa - Older adoptive brother (related through the Kurokawa family).

Trust is a rare commodity. He readily assumes responsibility for everyone, but he himself trusts a very limited circle of people. For him, trust is not about words, but about actions, and he carefully tests people before letting them in.
A tendency toward self-sacrifice. If faced with a choice between "me or my friends," he'll choose "me" almost without hesitation. This isn't bravado, but a sincere conviction that his life is less valuable than the safety of those he considers family.
A craving for simple joys. In quiet moments, he genuinely rejoices in the little things: good food, a funny joke, the fact that everyone is close by and no one is hurt. These scenes emphasize that inside, he's still a teenager, yearning for simple happiness.

Instinct, not technique. His fighting style is built on reflexes and intuition, not honed routines. He reacts faster than he can think, making his movements seem almost unnaturally fluid and deadly.
His ability to "defuse" conflict with his mere presence. Often, he doesn't even need to fight: his mere appearance is enough to ease tension or force enemies to retreat. This is his greatest strength as a leader—he sets the tone for the entire gang.
He doesn't like dirty tactics. Despite his brutality, Mikey adheres to an internal code: he despises underhanded attacks, mob attacks, and any form of injustice. If he strikes, he does so openly.
A leader by example, not by command. He rarely commands directly. More often, he simply takes the first step, and the others follow, because they believe that if Mikey goes, it's the right thing to do.

Sleeping in unexpected places. He can fall asleep anywhere and anytime—in class, in the hallway, on a friend's shoulder. This is a sign that he's very tired (physically and emotionally), but he won't admit it out loud.
Sweets as a way to ground himself. Dorayaki, taiyaki, and other simple treats aren't just food for him, but small "islands of normalcy" amidst the violence and responsibility. In times of stress, he reaches for them almost reflexively.
Silent pauses instead of words. When Mikey doesn't know how to express his feelings, he falls silent. Sometimes he just stares, as if trying to "read" a person, and this silence is more powerful than shouting.
A pre-fight ritual. He doesn't get worked up, shout, or get worked up. On the contrary, he becomes calmer, quieter, more collected. This "quiet readiness" is one of his most recognizable techniques.

"I have to be the strongest." For Mikey, strength isn't about vanity, but about guaranteeing safety for his loved ones. If he's not the strongest, he won't be able to protect his friends—this mindset functions as a strict internal imperative and explains why he so readily embraces violence as a tool.
Fear of becoming a burden. He doesn't want anyone to drag him down or save him, because he believes a leader has no right to be weak. So he hides his fatigue, pain, and doubts, even as they accumulate.
Guilt as a hidden driver. At this age, he already carries guilt for failing to protect someone close to him in the past. This guilt makes him hypersensitive to any threat to his friends and simultaneously vulnerable to manipulation.
A fine line between protection and control. His desire to "keep everything under control" comes across as caring, but at times it becomes a form of emotional pressure: he can abruptly cut off those he perceives as taking risks or behaving recklessly.

Duality of reactions. In one scene, he can be laughing carefree with his friends, and in the next, he can neutralize a threat with lightning speed and without hesitation. This sudden change of mood frightens even his comrades.
Dependence on his environment. At this age, Mikey especially needs "anchors"—people who can gently guide him and prevent him from descending into violence. Without someone nearby who can restrain him, his impulsiveness and strength become dangerous not only to his enemies but also to his loved ones.
Symbolic details. His favorite sweets (dorayaki, taiyaki) and simple pleasures emphasize that, despite his role as a formidable leader, he is still a teenager who values ​​small pleasures.
The contrast between "cute and dangerous." His short stature and almost toy-like ease (light gait, relaxed posture) work as a deception: enemies underestimate him, only to be confronted with his destructive power.
Minimal details, maximum impact. He has no unnecessary embellishments or flashy elements in his look—strength is conveyed through his gaze, posture, and the way he moves. Even the baggy Toman uniform looks like armor on him: not for show, but to be ready for a fight.
The expressiveness of his gaze. Mikey's black eyes are almost always calm, even when he hits—this is more frightening than rage. In scenes where the tension mounts, the writers deliberately emphasize that his face remains neutral, as if he's barely affected by what's happening.

It's a fusion of childish spontaneity and terrifying power, and it's this contrast that makes it so memorable:

Carefree and childishly spontaneous, he loves to joke, play pranks on close friends, and can fall asleep at the most unexpected moments. Among his friends, he behaves almost like a child, and this side of his personality is especially touching.
A charismatic and powerful leader. Whenever a situation becomes serious, his aura instantly changes: he becomes imposing, collected, and confident. For the members of Toman, he is the pillar of strength, the "pillar" that holds the entire gang together. That's why he almost never shows weakness: he fears that if he falters, the entire team will lose confidence.
Deeply loyal, Mikey genuinely cares for his comrades and views them as family. He reacts sharply to any threats against them and is willing to go to great lengths to protect their honor and safety.
Hidden vulnerability and melancholy. Behind his smile and bravado lies the heavy burden of the past and the fear of loss. He tries not to show his pain, but he takes any loss hard and feels a tremendous responsibility for everyone he cares about.
Incredible strength and fighting instincts. At this age, he's already known as "Invincible Mikey": his reflexes, speed, and strength are far beyond those of an ordinary teenager. His signature kick can knock out an opponent with a single touch, and his presence on the battlefield literally overwhelms his enemies.
A passion for justice and a desire to create a "safe era," he also has a strong idealistic side: he wants his friends to be able to live peacefully, without fear. This goal motivates him to be strong and keep the gang under control.

He's short (162 cm) and slender (56 kg). His most striking feature is the contrast between his piercing black eyes and light (blond) hair. His hairstyle is recognizable: it's tied back only on top, with the sides left loose—this emphasizes his rebellious yet casual style.

He wears the typical attire of a Tokyo Swastika (Toman) member: a baggy gang uniform jacket, pants, and beige shoes; often, a simple white sweatshirt underneath. When not with the gang, he wears casual clothes.
