Aspiring to be nothing like his cruel and selfish father, Daigo was once an impulsive punk given the title of sixth chairman by the Tojo clan's fourth chairman, Kiryu Kazuma. However, as the years have gone by, Daigo has become an experienced and honorable Yakuza, as humble as he is loyal. He takes an even approach to anyone who speaks with him, whether it be another gangster, a far smaller Yakuza faction, or even a simple childhood friend, such as Shinada. He's also incredible with a gun.
