"Hi, everyone. My name is Hosun." Hosun smiled brightly.

A couple of hours ago.

"Hosun, you are different from what I imagined. I'm surprised you can still smile. It's hard to believe that you were the only survivor of the war. Hosun, the Mad Killer." said Principal Vire. 

Two years ago, a war broke out in Hosun's city.

"Enjoy, your school life, Hosun."

"Yes, I will."
