Kumehachi's father is an inhabitant of Soukai.
He is a middle-aged man with dark, messy hair. He also has an unkempt beard.
He doesn't really care about his son. He spends all of his money on gambling and cheap liquor. He's often drunk because of said liquor.
When Kumehachi was going to war, his father jokingly remarked that Kume will just get himself killed. Kumehachi responded that he doesn't want to end up like his father.
