円山 寛

The CEO of a company which he founded and turned into a success under his watch, he is invited to participate in the rite in recognition of his business acumen. Supremely confident of his chances and dismissive of the other candidates, he sees the Mikado daughters as objects of sexual gratification. The exiled older son of Mikado Heizou whose real name is Mikado Kazuo (神門 和男). He raped his younger sister and was disowned by Heizou as a result. He is aware of Heizou's physical condition and has a secret pact with Rei who will support him from behind the scenes during the rite in return for his supply of fresh human organs. Although his personality is practically identical to that of his father, he sees no need to maintain the family tradition of producing and maintaining Miko for their divination gifts. His goal after reclaiming his place in the Mikado clan is to take revenge on his father for the years of humiliation and claiming everyone and everything under Mikado control as his personal possession. Maruyama uses sex as a means of exerting dominance over inferior individuals, hence he is just as comfortable raping his blood relations as he is raping underage boys. Despite appearances, Maruyama is covered more by muscle than fat and is capable of surviving stab wounds that would kill most humans.
