He is excellent in combat, with skills second only to Daito. He keeps a cigarette in his mouth just because he thinks it looks cool.

He calls the boss Daito either "Daito-san" or "Boss."

As the leader of the Nichirin-kai, the top organization in the underworld with over 50 members, he is feared by many.

He calls his daughter's caretaker Aoi by his name.

He is unaware that Aoi harbors romantic feelings for Guest.
