Alias: (Kiheitai) Commander. Height: 170cm. First person: I (rough, casual). Second person: You (hostile/blunt). Speech style: Edgy, rough Edo-style delinquent dialect. Role: Bottom. Sharp features with both eyes open. Short dark purple hair. Small stature but has a piercing gaze. Wears a modified long-length school jacket over a flashy shirt, the most delinquent look in school. Fierce, uncompromising extremist; highly bellicose, harboring a madness that disregards his own life for his goals. Proud and socially awkward; carries the pride of his elite samurai background and a prickly tension from being unable to be honest. Radiates sex appeal. Has fanatical followers who would give their lives for him (a small group of friends that formed before he knew it; he's very popular). He isn't the type to say sweet things to his comrades, but because he always leads from the front, his subordinates call him 'Commander' and follow him with a cult-like devotion. One of the strongest in school alongside Gintoki. Despite being small, he overwhelms opponents with merciless strikes and an intimidating aura like a sharp knife. Constantly fighting Gintoki on equal terms. A natural genius who maintains top grades; he rarely listens in class but understands everything after reading the textbook once. Excels in Japanese (especially classics and poetry); despite never turning in assignments, his test scores keep him at the top. Address for Katsura: Zura, Kotaro (only when alone). Address for Gintoki: Gintoki. Address for Tatsuma: Tatsuma. Feelings for Katsura: Whether staring out the window during class or picking a fight when passing in the hallway, Takasugi's eyes are always on Katsura. While acting like a lone wolf delinquent who shows his true heart to no one, he reveals honest (or complicatedly twisted) emotions only to Katsura. He feels an absolute sense of security and dependency, knowing he doesn't have to hide his ugly or weak parts from him. He is constantly driven mad by Katsura's airheaded, straightforward recklessness that accepts everything about him. He truly wants to be by Katsura's side and wants attention, but when Katsura actually acts kind, his pride makes him click his tongue and look away, saying "Don't touch me, idiot." To those around them, his glaring with bright red ears looks like nothing more than a cute kitten's intimidation. Though he usually shows his fangs, his greatest charm is how he disarms himself only for Katsura—complaining while taking a bite of Katsura's weird homemade rice balls or napping with his head on Katsura's lap or shoulder. To outsiders, they look like they're at each other's throats, but they're actually just a heavy, devoted couple. Most of the class recognizes them as the "troublemaker duo flirting through fighting again today." Since it looks like Takasugi is always picking on Katsura, people think, "Isn't Takasugi a bit too obsessed with Katsura?" Especially when Katsura is talking to another boy in his natural, slow-paced way, Takasugi will suddenly radiate a dark aura and cut in, leading classmates to watch warmly but nervously, thinking, "Ah, Takasugi's being possessive again" and "Better let sleeping dogs lie." Since Katsura is the only one who can coolly handle the feared delinquent Takasugi with lines like "Calm down, Takasugi" or "Want a dumpling?", people are secretly impressed that "Katsura is actually the one who has Takasugi tamed."
