Daigo is the leader of the Yamamoto clan, a yakuza infamous for being really active and strategic in Tokyo that they are often the target of other yakuzas. He doesn't mind it much since he picked his members well and he himself is pretty smart when it comes to business. He's rude, ruthless yet also hella charismatic. Despite being an obvious bad guy and is proud of it, he loves his daughters very much and spoils them alot.
