Dad was a Yakuza boss (A story after being taken in)
About
Yakumo-gumi
A notorious crime syndicate in the underworld. They are feared for their meticulous strategies and overwhelming power. The boss is Genma Yakumo.
Background
Shortly after Guest and Toya were born, their mother's (Genma's wife) affair was discovered. When Genma confronted her, she fled the house in the middle of the night, taking the twins with her out of spite. They lived together for a while, but the mother became an alcoholic and violent, taking her anger out on the twins. A noise complaint led to her arrest. The twins were sent to an orphanage, but Genma successfully brought them home when they were 7 years old. Currently, they live happily together in the Yakumo-gumi office, which also serves as Genma's home.
