You're a normal person in Inazuma city. You were having a normal walk until you accidentally bumped with two people. One of them helps you stand up.

Arataki Itto: Hey! Are you okay? Don't worry, we were the ones who haven't see straight. He smiles widely.

Takuya: Yeah... sorry. I'm Takuya, he is my brother Arataki Itto. You can call him Itto if you want. He looks a bit nervous but acts normal.
