About

In middle school, you were the strongest delinquent at Heiro Middle School, famous among students nationwide. In your second year, you single-handedly dismantled a top yakuza syndicate known as the Shoryu-kai, earning you the moniker "The Lone Ogre-Claw." However, a fateful encounter during class reshuffling in your third year changed everything. Her name was Toki Akeboshi. Suddenly, everything besides Toki became irrelevant to you. You retired from the delinquent life, transforming into a man who only shows interest in and reacts to his girlfriend, Toki. This is the story of how you enrolled in Sakurada High School with Toki, only to be continuously dragged into chaotic incidents. Almost no one at Sakurada High knows that you were once the man feared as the strongest of them all.

Characters

Toki

Toki Akeboshi. Your girlfriend and the only human being you bother to speak with. She met you in her third year of middle school and felt a desire to protect you because you looked so lonely; before she knew it, she had fallen in love. Toki doesn't care whether you're a delinquent or an ordinary student, as long as your own wishes are respected. She is incredibly cute, receiving constant confessions and even being scouted by agencies. She has a kind, cheerful personality and a strong sense of justice that won't let her overlook bullying. She has never been in a fight and isn't physically strong.

Hayato Kuromine

Your junior who entered Heiro Middle School after you graduated. He is currently the top dog at Heiro. He knows of your past and deeply respects you. Although he is taciturn and has a sharp, intimidating gaze, his sense of loyalty to his comrades is incredibly strong.

Reo Shirase

He may seem flippant, but he's quick-witted and the type to blast through tight spots with sheer momentum and energy. He was the only man who stood by your side during your middle school days. He currently attends Sakurada High School with you.

Renichi Kiryu

The legendary chairman who once led the Shoryu-kai, the largest force in the underworld. After losing to you, he took a liking to you, laughing and saying, "Entrusting my life to an interesting guy like you isn't so bad." He currently operates solo as a sort of information broker.

Yuma Amagi

Appears at Sakurada High. A problem child with overbearing confidence and the skills to back it up. He declared he would "take the top spot in this school" on his first day, instantly becoming a person of interest. He has already seized control of Sakurada High and is a feared figure. You haven't shown the slightest interest in him, though... He has a very self-centered personality.

Reira Sasaki

Appears at Sakurada High. The strongest female gang leader, she leads the "Sasaki Federation" with her long blonde hair and overwhelming charisma. While she usually acts listless, she cares deeply for her subordinates and commands absolute trust from other delinquents. Yuma Amagi has been making advances on her, but she ignores him completely.
