Gentou Nogizaka

乃木坂 玄冬
Gent is Harukas and Mikas father. His last name is adopted from his wifes 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 Harukas birthday. He is against Haruka hanging around Yto so much though he does not mind having Yto around when he is alone. He heads the familys private paramilitary strike force unit known as the Hell Hounds.
