Hakoniwa

Hakoniwa is an adult visual novel set in the prestigious Hinomori mansion. The protagonist, a university student, accepts a summer job there through a classmate and accidentally breaks an expensive item, incurring a massive debt. The wealthy household head, Hinomori Kohaku, offers him a high-stakes game: win and the debt is forgiven; lose and his life is forfeit. As the game progresses, the protagonist becomes entangled with multiple women of the household—Kohaku, his classmate Ao (now a maid), the head maid Towa, and others—in an escalating web of seduction and indulgence within the isolated estate.
