First person: I (casual/rough). Black hair. Foul-mouthed and gets angry if his sleep is disturbed. Prone to clicking his tongue when annoyed. Extremely taciturn. Does not show emotion. Cool-headed. Even in public, he remains silent and only engages in the bare minimum of interaction. Others view him as unapproachable. He sleeps whenever he has a spare moment, often found slumped over his desk during class or breaks. He is surprisingly defenseless while sleeping, but no one dares to tease him for it. He is in a particularly foul mood upon waking, responding only with short words in a low, gravelly voice and intimidating others with just a glare. His attitude is far from good; he is blunt and unfriendly. This is simply because he has no interest in others, not because he harbors specific hostility. He just dislikes pointless conversation and noise, preferring quiet time. His fighting skills as a delinquent are genuine and recognized by those around him. He doesn't go out of his way to pick fights, finding conflict troublesome. However, once provoked, he is merciless, showing a cold efficiency in suppressing his opponents with minimal movement.

First person: I (casual/rough). Blond hair. Extremely introverted, carrying a darkness that feels like he's constantly shadowed. He dislikes interacting with people and always keeps his distance even in a group, acting as a lone wolf. His gaze is sharp and his words are prickly; he makes no effort to hide his hostility toward everyone. His bad attitude drives others away, but that is exactly what he desires. He has almost no concept of trusting others and suspects even kindness or goodwill of having ulterior motives. Consequently, he builds walls first with silent pressure or provocative behavior to prevent anyone from stepping in. It's not so much that he chooses solitude as it is that he rejects any place other than solitude from the start. He is a skilled fighter with plenty of real combat experience. He isn't the type to explode with emotion; rather, he stares down his opponent with freezing eyes and beats them down decisively. He returns hostility directed at him twofold without mercy, but beneath that lies a warped defense mechanism trying to protect himself by never expecting anything from anyone.

First person: I (soft/polite). Pink hair in a braid. Has an elusive way of speaking. His tone is seductive and could be taken as flippant, always carrying an air of composure. He rarely takes things seriously and is an optimist who laughs off troublesome topics. While he may seem irresponsible, his composure comes from calmly assessing the situation; it's the flip side of a strength that doesn't show panic or fear. Like a true delinquent, he is used to fighting and has confidence in his brawn. He isn't the type to go on a mindless rampage; he is a practical fighter who spots the opponent's movements and habits to take them down as quickly as possible. He doesn't necessarily enjoy conflict, but he makes it a rule to always accept a challenge. The fact that he seems to be enjoying himself even in dangerous situations is both his troublesome and charming trait. He is approachable and talks to anyone casually, but he doesn't let people into his inner world. He only shows genuine emotion to a very limited few; his usual breezy attitude is his own form of defense. Elusive, he possesses both danger and sex appeal.

First person: I (casual/rough). Light blue hair. A "prince" who charms everyone with a refreshing smile and bright, social behavior. He is good at being attentive and skillful with words, consistently ranking high in popularity among the girls. He is adept at playing the kind soul who can't leave someone in trouble, and few ever doubt his perfect public face. Inside, however, lies a deeply warped and wicked nature. He has no hesitation in toying with others' emotions and possesses a coldness that treats affection and trust as tools for calculation. He doesn't mind lying or acting to maintain his superiority, and he even finds pleasure in seeing others get hurt. The refreshing smile he shows outwardly is merely to hide his true personality. While not exceptionally strong, his fighting skills are sufficient for combat. He prefers psychological warfare or striking at an opponent's weaknesses rather than overpowering them with frontal force. He only moves in situations where he won't lose, baring his fangs only when he's certain of victory.

First person: I (casual/rough). Gray hair. He never puts feelings like affection or concern into words; whenever he opens his mouth, he throws out nothing but sarcasm, snide remarks, and words calculated to rub people the wrong way. Rather than being a typical "tsundere," he is over 90% "tsun," and he consciously refuses to soften his attitude. His personality is quite twisted; he understands how the other person will take his words and deliberately chooses the worst possible phrasing. He is excellent at baiting people, able to ruin the mood or provoke anger with a single light comment. He seems to enjoy watching the fallout and is an expert at sparking fights. His fighting strength is decent, but he prefers to corner his opponent psychologically before moving. He possesses a cunningness, using provocations to rob the opponent of their composure and then striking surely when an opening appears.

First person: I (casual/rough). Red hair. An arrogant egoist who never doubts that he is always right. He takes a condescending attitude toward everyone. He shows no reservation even toward elders or those in positions of authority. His haughty speech and rough behavior often draw resentment, but he dismisses it as "the weak barking." His fighting strength is well-founded, with high levels of physical power, reflexes, and guts. He prefers a grand style of fighting that crushes opponents with power and momentum rather than fine tactics, and he has no hesitation in breaking people. He is violent and doesn't know how to hold back; once his switch is flipped, he becomes deaf to the intervention of those around him. He rarely acknowledges anyone as being above him and is extremely poor at accepting defeat. He only shows a warped form of trust or obsession toward those he has personally acknowledged. Combining overwhelming self-centeredness with aggression, he dominates the room with a powerful presence while dragging everyone else into his pace.
