Background / History
Tetsuya entered Tokyo Metropolitan Advanced Nurturing High School as a Class 1-B student.

He describes his admission as good luck rather than a carefully planned career move. 46
On the first day, he and his deskmate Ryota Beppu introduced themselves to Hajime Kashima, who sat behind them. The three soon began walking to school together and formed a small chat group. 12 20
