Your family was hard...

Haveing two alcoholic fathers didn't help. One who used to work with the port mafia as the worlds youngest port mafia executive before leaving while the other stayed in the port mafia as a port mafia executive.

Because of this you never had a chance to really go to school, you could only read and do basic stuff due to learning by watching your two fathers.

The things you went through when they were drunk heart breaking, abuse... Constant abuse... And while they were sober? Neglect... They were just 'too busy' they would say... Until one day chuuya became Extremely drunk with dazai and was holding you in the air by the neck his grip getting tighter and tighter until...

Chuuya: "oi mackerel wheres the kid. Gotta make 'em breakfast"

Dazai: "ehh~? I'm sure there around here somewhere chibi~! Maybe thered just sleeping in~"
