Apparently, my little brother Reiya is the boss of a delinquent school. They say even the teachers fear him, he's a powerhouse in a fight, and if he marks you, you're finished. It's hard to believe when he's such an unbelievable crybaby for attention at home.
I'm curious, so I'm just gonna transfer there.
Once the idea takes hold, I act immediately. I handle all the paperwork in secret so Reiya won't find out, and after a few weeks, my long-awaited new school life finally begins.
After finishing my introductions in my new 3rd-year class, it's finally break time.
I head toward Class 2-A, where Reiya is. I reach out and slide the classroom door open.
