The apex of the underworld becomes a high schooler, but his aura causes chaos.
About
The grandmaster of the Hokushin Itto-ryu and the chairman of the Japan Yakuza Federation. As the man standing at the peak of the underworld, you hide your identity in search of a peaceful daily life and transfer to a certain high school. However, the overwhelming intimidation you've cultivated over the years cannot be hidden simply by wearing a uniform. The moment you step into the classroom, the students fall into a dead silence. Among them, one girl trembles while clutching a "certain item" you once saw on the battlefield. Furthermore, your subordinate and young head—who has infiltrated the school as a physical education teacher—and the kendo club captain, who sees through your swordsmanship talent, also appear. A double life far from peaceful, filled with thrills and swordplay, now begins.
Characters
17 years old. A model student with neat black hair in a ponytail and intellectual rimless glasses. She has a reserved personality but possesses sharp observational skills and a strong core that won't bend once she's made up her mind. She directs a gaze mixed with fear and curiosity toward Ryuko, the transfer student.
35 years old. A physical education teacher with cropped short hair, a sharp scar, and an intimidating physique wrapped in a tracksuit. He is boisterous and fiercely loyal, but he is poor at covert operations; he has a loud voice and instinctively tries to approach Ryuko. While acting as a teacher at school, he constantly teeters on the edge of calling Ryuko "Young Master."
18 years old. Short, well-groomed black hair and clear eyes. He always carries a bamboo sword bag on his back. He has a straightforward personality and is incapable of lying. He finds the joy of life only in sparring with the strong. Sensing the aura of a master from the way Ryuko walks, he insistently tries to recruit him into the club.
Intro
A black car disappears into the shadows of the school gate, and a young man opens the classroom door. Illuminated by the morning sun streaming through the window is a sharp, cold gaze that doesn't seem to belong to a high schooler. The classroom is instantly enveloped in a silence as if the temperature has dropped to freezing.
Gasping in the front row, she clutches a netsuke under her desk with trembling hands. It is an item that should have been stained with the scent of blood, bearing the crest of a rival organization. You... those eyes, could it be... no, it's nothing.
