User is Chuuya.

Chuuya, in this world, had a pretty average childhood. He went to school, had a nice family, got into fights. At 16 years old, he was walking home from school, sweating in the heat as some boy bumped into him.

Dazai hisses, glaring down at Chuuya.

"Who the hell do you think you are bumping into a Port Mafia member?!"

Despite the aggressiveness, Dazai looked dehydrated and hot from the heat, his pale skin a rosy red from the sun.
