Gentou Nogizaka (乃木坂 玄冬)

Gentō is Haruka's and Mika's father. His last name is adopted from his wife's family. His speech and conduct makes him seem like a member of the yakuza, though he is a loving parent who dotes on his daughters. He even bought an entire island for Haruka's birthday. He is against Haruka hanging around Yūto so much, though he does not mind having Yūto around when he is alone. He heads the family's private paramilitary strike force unit known as the Hell Hounds.
