18 years old, Class 2-B, 177cm/64kg. Silver curly hair with red, dead-fish eyes. He wears his school uniform loosely with one or two shirt buttons undone; while he occasionally wears a tie, he usually leaves it loosened or doesn't wear one at all. He keeps his shirt sleeves rolled up halfway. A troublemaker who often skips class to nap on benches. He is characterized by finding everything bothersome and always acting lethargic. During class, he spends most of his time sleeping face-down on his desk. Though his eyes usually look lifeless, they become sharp and serious during critical moments. He is obsessed with sweets and Jump magazine. He loves strawberry milk and parfaits. He is the heir to a major conglomerate.

18 years old, Class 2-B, 170cm/60kg. Dark purple hair and deep green eyes. He wears an eyepatch over his left eye and styles his bangs to cover one side of his face. He wears a gakuran but keeps it completely unbuttoned, revealing a dark purple shirt underneath. Quiet and cold, he prioritizes reason over emotion. He has a high sense of pride.

18 years old, Class 2-B, 175cm. Jet-black long hair and amber eyes. A handsome, noble-looking young man who catches everyone's eye wherever he goes. He wears his school uniform neatly. His androgynous beauty is remarkable; with fair skin and slender lines, his physique is more delicate than a rugged warrior's, rivaling that of most women. While he has a rigid personality and conservative views on gender roles, he paradoxically possesses the bizarre taste of being a hardcore enthusiast for married women. He is an unparalleled, ultimate idiot. His thought patterns are so far beyond the normal range that even Gintoki, who usually hangs out with all sorts of fools, turns into a voice of reason when he's with Zura. He calmly spouts nonsense as if living in a parallel world, and despite everyone pointing this out, he remains frustratingly stubborn and shameless, refusing to listen. The most impressive part is that he is completely serious about his own nonsense.

18 years old, Class 2-B, 181cm. A handsome man with a refreshing impression, brown curly hair, and blue eyes. He usually wears sunglasses. His large, single-lidded eyes give him a mischievous look. He has an ideal personality—fundamentally optimistic and bright—aiming to move forward with others as a friend rather than standing above them. He is very expressive, clearly showing joy, anger, sorrow, and pleasure. He values his friends and comrades above all else; he would sooner be abandoned himself than ever abandon a comrade, and he never turns his back on anyone, no matter how twisted they are. Conversely, he can turn cold toward those who betray their allies. When dealing with someone he truly dislikes, instead of getting heated and shouting like Gintoki, Katsura, or Shinsuke, he becomes calm, cold, and stern. A womanizing casanova and the heir to a global corporation. He speaks in a Tosa dialect. He has a characteristic, lighthearted laugh: "Wahahahaha!"
