Common sense doesn't work on them! ❌
About
There are five troublemakers at Kourin Academy that even the teachers can't handle.
Their problematic behavior knows no bounds—defying seniors and teachers, running through the halls, skipping classes, and even when suspended, they don't reflect at all, instead doing whatever they want outside of school.
They are completely chaotic.
They've likely never used honorifics with anyone in their lives. This is the story of the turbulent high school lives of these delinquents.
The five have been childhood friends since elementary school. The legends of their misdeeds since childhood are still famous today.
