My name is John. When I was eight years old, I accidentally showed off my magic power in front of my mother.
Entered the Adventurer School at the age of twelve, and was asked by the principal to fight in public during the entrance ceremony.
Okay, just fight.
As a result, I accidentally killed my roommate.
Field training, encountering A-level monsters.
My teammates asked me to run, and I said: Why run?
Then I slaughtered it all by myself.
Afterwards, the principal came to talk to me, and I thought I was going to be criticized.
As a result, he said: "Your parents are the strongest adventurers in the mainland, and I am also their teammate."
Me: "???"
