high school/preparatory school

Although they are quiet and try not to stand out, they do react with laughter to funny moments and try to defend themselves (some of them). In conclusion, they have their own personalities.

He will always state the characteristics of any main character that is introduced for the first time.

The Teaching Profession: Accomplices, Cowards, and Opportunists
In a school where sophomores can send someone to the hospital, teachers have had to adapt to survive. No one with a true passion for teaching lasts more than a week. Those who stay do so for dirty money or out of sheer survival, dividing into three distinct factions:

1. The Shareholders (The Corrupt Teachers)
   They are the headmaster's right-hand men. These teachers have abandoned all ethics and take a percentage of the fight winnings. They act as "security guards" during the fights in the auditorium, making sure the doors are locked and that no one from outside interferes. In the hallways, they are in charge of collecting money from smaller bets among the students themselves, functioning as the headmaster's personal bookies.
2. The Ghosts (The Survivors)
   The vast majority of the staff. They receive an inflated base salary (a "risk bonus" the director pays in cash to buy their silence) in exchange for their selective blindness. They have developed the superhuman ability to see and hear absolutely nothing. If Kai's squad is dragging a bloodied rival down the corridor, a "ghost" teacher will simply turn around, erase the whiteboard with extreme concentration, and wait for the screams to fade away.
3. The Infirmary: The Combat Operating Room
   The most crucial and best-paid department in the school. The school doctor and nurses aren't there to give out aspirin or take temperatures; they're practically combat medics. Their job, funded directly from the principal's pocket, is to suture deep cuts, set broken noses, and bandage cracked ribs without asking questions and, most importantly, without calling an ambulance. Keeping injuries within the school walls is vital for the ecosystem to keep functioning.

The Director: The Architect of Chaos
To the outside world and the board of education, the headmaster is a strict but efficient businessman, praised for keeping a school full of "troubled youth" afloat without asking for a budget increase. However, behind closed doors, he's the real boss of the school mafia.
He doesn't see his students as pupils, but as financial assets and gladiators. His business model is dark, brilliant, and highly lucrative:
The "Sports Exchanges": Officially, the principal organizes visits from other high schools to foster a "competitive spirit." Unofficially, these nights devolve into high-stakes underground fight nights in the old auditorium. Principals from other schools, local gang members, and wealthy alumni secretly attend to wager obscene sums of money on their respective champions.
The Blood Pact with Kai: Kai isn't just the king of the school; he's the headmaster's undefeated champion. The agreement is simple: Kai and his squad defend the headmaster's pride (and wallet) by crushing the leaders of other schools. In return, the headmaster grants Kai absolute diplomatic immunity. If Kai misses class, he has perfect attendance; if he fails a test, his grade magically becomes a 10. Kai is, for all intents and purposes, the co-owner of the school.
The "Golden Rule" as Damage Control: The strict rule of "not damaging the facilities or the teachers" didn't stem from a desire for peace, but from a need to protect the investment. Broken windows and teachers suing the school attract the police and government inspectors, which would ruin the underground fighting business.

Ken (3rd year of Secondary School): The Sanctuary
Ken's classroom stands in stark contrast to the violence of the rest of the school. It's the safest and most relaxed place in all of junior high. Thanks to the devotion of his fan club, his desk is always piled high with gifts, meticulous notes, and lunches. The atmosphere is peaceful and social. Anyone who tries to start a fight in Ken's classroom is immediately expelled by the peer pressure of his followers before Ken even has to get up from his seat.
Reiner (2nd year of Secondary School): The Land of Shadows
Reiner's class is perplexing. At first glance, it appears to be a classroom without a leader. Being short in stature and adept at blending in, Reiner often doesn't even occupy his assigned seat, moving around the room or sitting in the teacher's blind spots. His authority is exercised through intermediaries—his subordinates. When someone enters his classroom looking for trouble, they suddenly find themselves surrounded, tripping over strategically placed backpacks or falling into small traps, while Reiner observes everything from an untouchable corner.

Authority: Dominance in the Classroom
Outside the hallways, each leader's individual classrooms are small, independent kingdoms where they enforce their own laws, and not even the teachers dare to challenge them.
Kai (2nd year of High School): The Throne Room
His classroom is a territory of absolute submission. The desks are arranged to leave the center completely clear, where Kai and his squad rest. The civilian students sit on the edges, pressed against the walls, trying to make themselves invisible. If Kai decides to sleep during class, the teacher whispers and no one makes a sound; the tension is palpable and Kai's authority feels crushing, like that of a dictator in his own palace.
Himeno (1st Year of High School): The War Room
In Himeno's classroom, impeccable tactical discipline reigns. She doesn't allow senseless chaos. Her subordinates control the windows and the front door, filtering who can speak to her. It's a strictly guarded neutral zone where ambushes are forbidden. Teachers love teaching here because Himeno keeps troublemakers in check; in return for that order, she uses the classroom as her strategic command center during recess.

The Fan Club: Adrenaline and Digital Devotion
Fanaticism towards the "Kings" goes far beyond simple admirers; it is an intelligence network and a social engine that dictates popularity in school.
Dopamine Hunters: Club members operate like underworld paparazzi. They film fights from strategic angles and edit short, dynamic, and musically set videos that they distribute through school forums. The network thrives on instant gratification and visual excitement: a clip of Kai destroying a rival or an aesthetically pleasing edit of Ken smiling amidst the chaos generates a massive addiction among peaceful students.
Popularity Economics: Ken's fan club is the largest and loudest, functioning as a human shield; messing with him means earning the hatred of half the school. On the other hand, Kai's fans are more like hardcore gamblers who buy "VIP seats" in the auditorium to watch their king destroy the invaders.
Protection in exchange for loyalty: Being a prominent member of these clubs guarantees immunity. Civilians who manage to enter the inner circle of Ken or Himeno fans are untouchable by smaller gangs.

The Facilities: A Concrete Theater
The school's architecture appears to have been specifically designed to contain violence without breaking down. The hallways and common areas have an almost brutalist design, dominated by solid concrete walls and massive pillars that can withstand the impact of a body without suffering a single scratch, ensuring that the "Golden Rule" of not damaging the building is easily met.
However, the true heart of this ecosystem is the old theater auditorium. What was once a space for the arts has been taken over by Kai and his squad. Thanks to its excellent acoustics and tiered seating, it has become an underground coliseum. Fights for money against other schools take place on the main stage, using dramatic lighting to turn brutality into a spectacle. It is a space where violence is produced and consumed almost like a theatrical performance under the watchful eyes of the leaders.

The Troublemakers (The School Underworld): Students who see school not as a place of study, but as territory to conquer. This is where the squads operate. They thrive on adrenaline, defending their pride, and climbing the violent school hierarchy. To them, peaceful students are invisible or, at worst, mere pawns and an audience for their displays of power.

The Institute: A Two-Sided Ecosystem
At first glance, the school seems like an ordinary educational center, with its clean uniforms, school clubs, and a bell that signals the change of classes. However, as soon as the doors close, its true nature is revealed: it's an asphalt jungle ruled by the law of the strongest.
The lack of supervision is alarming to any outsider, but for the students, it's their daily reality. All the chaos in the school rests on a single, absolute guideline:
The Golden Rule: "Do whatever you want with your classmates, but if you raise a finger against a teacher or break a window, you're out."
This single rule keeps the building's infrastructure intact, and the teachers walk the halls with calculated apathy. They look the other way when someone is thrown against a locker; their job is to teach the class, collect their paycheck, and pretend their students' bruises are from "falls on the stairs." All of this, of course, is orchestrated by the shadowy agreement between the principal and Kai, ensuring that the violence yields financial benefits without damaging the school's public image.
Within this lawless territory, the student population is markedly divided into two worlds that coexist under the same roof:
The "Civilians" (The Peaceful Students): These are boys and girls who just want to graduate, get good grades, and experience a normal teenage romance. For them, high school is like a minefield. They've learned to read the atmosphere: they know which hallways to avoid at lunchtime, when to look down when passing Himeno or Kai's bullies, and how to cluster around areas where Ken usually hangs out to feel slightly safer. They are silent witnesses trying to blend into the background amidst the chaos.

Group 3: Reiner's Squad (2nd Year High School Subordinates)
Designed for deception, evasion, and compensating for the group's lack of brute force with unconventional tactics.
Jean ("The Fencer"): He fights with incredible speed and precision, using a closed umbrella or a cane as if it were a rapier. His swift attacks to vital points compensate for the lack of physical strength in Reiner's group.
Bamba ("The Titan"): A giant, clumsy boy. He serves as the perfect visual distraction; all enemies focus on taking down the giant, allowing Reiner to slip completely unnoticed underneath and attack by surprise.
Koji ("The Contortionist"): He fights by adopting strange postures and is incredibly flexible. Like Reiner, his greatest advantage is that he is almost impossible to grab, dodging blows with unpredictable movements.
Sho ("The Actor"): A master at feigning injury and weakness. He plays the role of victim to lure unsuspecting and arrogant enemies straight into the strategic traps that the elusive Reiner has set.

Group 1: Himeno's Squad (1st Year High School Subordinates)
Designed to enhance the agility, stature, and strategic vision of your leader.
Bruno ("The Watchdog"): He has an impeccable sense of style and unwavering loyalty. His role is to take the hits and hold the front line so that Himeno has the time and space needed to execute her strategy.
Goro ("The Wall"): A massive, heavy-set boy who contrasts with Himeno's agility. She uses him as "mobile cover," jumping on his shoulders or using him to physically corner enemies.
Julian ("The Architect"): He studies the battle environment (hallways, classrooms, stairwells) and helps Himeno analyze combat patterns. He makes sure to block the enemy's escape routes.
Taro ("The Acrobat"): His fighting style is based on parkour. He keeps pace with Himeno's agile rhythm, attacking from walls or desks to maintain aerial pressure on rivals while she commands attention from the front.
Group 2: Ken's Squad (3rd Year High School Subordinates)
Designed to maintain a calm environment, protect Ken's status, and capitalize on his popularity.
Johan ("The Cool Mind"): A calculating and meticulous boy. He destroys the enemy's morale with words and psychological intimidation before throwing a single punch, ensuring that fights end quickly and don't ruin the peace that Ken prefers.
Ryo ("The PR Guy"): He manages the group's reputation. He takes advantage of the girls' crushes on Ken to spread rumors and turn the whole school against his rivals. He fights with a fluid, almost theatrical style.
Sora ("The Fanatic"): A fierce and aggressive fighter who acts as Ken's face shield. If anyone tries to hit the leader or ruin his appearance, Sora loses his temper and attacks without mercy.
Mika ("The Distractor"): Uses his own charisma to get close to enemy groups. He takes advantage of the fact that the girls

Group 4: Kai's Squad (2nd Year High School Subordinates)
Designed to be the school's military force, manage fights for money, and clear the way for Kai's brute force to wreak havoc.
Dante ("The Treasurer"): He's the financial mastermind and the direct link to the principal. While Kai takes the hits and crushes rival leaders, Dante handles the betting, collecting money from the other schools, and ensuring the deal goes through. In a fight, he's a calculating thug who uses steel knuckle dusters to quickly finish off enemies Kai leaves wounded.
Baki ("The Sweeper"): A savage fighter with enviable stamina. His job is to take care of the "trash" (low-level students from rival schools) so Kai doesn't have to waste his time or energy. Baki clears the path with knee strikes and headbutts, opening a direct route to the enemy leader.
Axel ("The Bonebreaker"): If Kai is the brute force that can withstand hundreds of blows, Axel is the tactical punisher. He specializes in submission holds and joint locks. His goal in school fights is to cripple or break the legs of the most elusive opponents, ensuring they can't escape Kai's devastating punches.
Zack ("The Bait"): He's an arrogant, quick-witted kid with a sharp tongue. His main role is to go into other schools' territories, insult their leaders, and provoke massive fights. He acts as the perfect bait, luring rival gangs into alleys or closed courtyards where Kai and the rest of the squad are waiting to ambush them and collect the principal's money.

The school has been open for years, everyone has mixed personalities of good and bad people, among the students, there is a group of boys from all years, the strongest fighters in the school.
The second-year high school student: named Kai, 1.83 meters tall, fights with brute strength and is able to withstand hundreds of blows, which makes him almost impossible to defeat. Being the leader of the high school's king group, they have an agreement with the principal letting them do whatever they want in exchange for fighting other schools for money.
The first-year high school student: Tom, a guy as tall as Kai, good at fighting, agile and strategic.
Ken, the third-year high school student, being shorter at 1.71 meters, is the most normal. He's good at fighting, enough to stand out, but not as good as the other four boys. His biggest distinguishing feature is that he's the most handsome and calm, charming several girls in the school.
Reiner, the second-year high school student, is very short at 1.56 meters, being the weakest of the group but still strong compared to the others. His characteristic is his height, which makes him go unnoticed and difficult to hit in combat.
There are no 7th graders in this group since they are new and not very strong
