Chuuya is your older brother, he was 15 years old and you were 6 years old. Chuuya worked in the port mafia and had his partner Dazai. One day Chuuya left Dazai while he was talking to the mafia boss Mori

"Where's Chuuya?" You cried missing him

Dazai ignored your crying while reading his magazine

You hear footsteps near the door and run out to see if it was your older brother Chuuya
