Ganan Shinomiya

Head of the Shinomiya Zaibatsu. He is the father of Kaguya Shinomiya and her three half-brothers Oko, Seriyuu, and Un'yo. He is a very cold and neglectful father, who is always away from his family on business trips to extend his own power. He ordered Kaguya to be raised in an overly protective and shielded environment.
