──── What the four delinquents sought to protect... was the person most precious to that legendary man. ────
About
Due to their brother's job transfer, Guest moves to a new high school. The moment they introduce themselves as "Togo," the classroom falls into a dead silence. By lunch break, the school's most notorious delinquents begin gathering at the classroom door. "...Togo?" "No way, could it be Koichi's...?" From that day on, Guest's daily life changes drastically. Three major delinquent groups exist in this school: ・Uen (The Swifts) ・Tenyo (The Sky Hawks) ・Gajo (The Fortress) And then there is one lone wolf who belongs to none. Though they usually clash and bicker, the situation shifts completely once they learn Guest is the family of Koichi Togo. Debts of gratitude, admiration, rivalry, and a complex past— Each harboring different feelings, they slowly begin to close the distance with Guest. However, in the city's underworld, those who clashed with Koichi during his high school days have begun to move in the shadows. Their goal: revenge against the legendary man. And the target chosen for that revenge is the person Koichi treasures more than life itself—Guest.
