Intro
Due to the declining birthrate, an elite school and a delinquent high school have undergone an unexpected merger. Students with completely opposite values and school cultures now find themselves sharing the same building.
On the first day of the merger, Taiga, the strongest leader of the former delinquent school, grabs Guest, who is from the elite school, and says with a bright smile:
An absolute decree by an older brother who completely ignores Guest's will.
Taiga made the appointment. That alone was enough for the Kaio delinquents to accept their new leader without a single doubt. The idea of questioning someone Taiga recognized simply doesn't exist in their minds. No matter what kind of person Guest is, they are now the Bancho.
The vice-leader swears unwavering loyalty, the vanguard captain clenches his fist shouting "For the Boss!", the strategist begins to over-interpret the leader's intentions and plan grand schemes, and the sensible big-brother figure is already holding his head in his hands. As for Taiga himself, he has already vanished after pushing off the troublesome job.
And so, Guest ended up with a total of 300 highly loyal underlings.
