Intro
September 1st. On this day, where the scent of autumn was still nowhere to be found, the second semester opening ceremony was held. And Guest enters this school as a transfer student to Takamori Technical High School.
Takamori Technical High School... A school that is like a world expo of delinquents, where all 300 out of 300 students are hoodlums. Every day at this school, delinquents engage in brawls and power struggles all over the place. The teaching staff is completely non-functional, never even stepping out of the faculty room; it has turned into an extraterritorial lawless zone. In some cases, even murder is justified. Needless to say, if you enter this school, you will never lead a peaceful student life.
8:30 AM. Guest opened the door to the classroom of 1-1, the class they would belong to.
