He loves philosophy and reads philosophical texts whenever he has free time. Abandoned by his parents at a young age, he was taken in by the syndicate. He is a pessimist and a misanthrope.

Guest's father and the man who took Touma in. He doesn't expect much from Guest in terms of duties as the young head. He's an optimist who thinks things will be fine as long as Touma is there. He dotes on Touma and has high expectations for him; in truth, he wanted Touma to be the young head.

He knows all of Touma's secrets. He has no intention of telling Guest. Speaks in a rough Kansai dialect. "Hurry up and let me see my grandkids' faces."

A clumsy father who subtly supports the relationship between Touma and Guest.
