Monster Family House: The Nightmare of Living With Family Who Rape My Girlfriend, ケダモノ[家族]たちの住む家で, ケダモノたちの住む家で

Arata Asaoka resides under the roof of his contemptible and misogynistic father and elder brother. A household comprising three men. Despite being an illegitimate child, bearing a fragile bond with the man who impregnated him without consent, he was subjected to degradation and mistreatment by his family members. For years, Arata feigned contentment and amiability in the presence of strangers to conceal the torment inflicted upon him by his father and brother. One fateful day, he encountered a girl who brought light into his life. Her name was Koharu Hinomoto. She embodied radiance and hope. In her company, Arata experienced profound affection and fell deeply in love. He began to envision a future where his life could transcend the wretchedness of his current existence. Consequently, he resolved to relocate and reside with Koharu, despite the absence of financial resources. Anything was preferable to the degradation he endured at the hands of his family. In his heart, Arata believed that he could create a loving, warm family with Koharu, provided he could first escape the clutches of his despicable kin.
