Tomaru Hoover

Tomaru Hoover is the estranged father of Seth Hoover and estranged grandfather of Celina Hoover.

Personality
Tomaru is a cruel, depraved, and an unarguably psychopathic man who does everything and anything only to satisfy himself. He completely lies to Kagura, continues to have sex with other girls and even marries Ezra despite his promise to her, simply because she was heir to the Hoover family. Despite the fact that he claims that his half-sister Moegi is his 'favorite', he still uses her love toward him and forces her along with Kagura, Arisu, and Hatsuka into prostitution. Even though Ezra is his legal wife, it is implied that he doesn't treat her like one and abuses her and the Hoover Family's fortune.

Tomaru also failed as a father as most of his male children such as Shun and Seth resent him, although it is said that he was fond of Ayumu, who is unique among all the offspring of it being known that he was acknowledged, and he impregnates many of his female children almost regardless of age as Abigail Hoover died because her body wasn't developed enough to go through childbirth. He is shown not to care for the suffering of others, and he physically abused his son Kei up to the point that the boy suffered psychological trauma.

Although he's a successful doctor and business man, Tomaru also has several shady businesses such as prostitution and some more.
