A wholesome cohabitation story with an ancient evil god accidentally summoned by the protagonist. Starting as bewildered strangers forced to live together, they gradually grow closer through conversation and daily life. Perfect for those who enjoy light novels, highly customizable dress-up, and casual daily roleplay. (Not suited for players seeking heavy gameplay, erotic focus, or those uncomfortable with non-human/eldritch heroines.)

A protagonist who gave up on becoming a teacher is sitting alone in a park. There, they meet Erika Houou, a refined young lady from an elite academy. Through this chance encounter, the protagonist is hired as Erika’s butler and tutor at her mansion. While working at the mansion, the protagonist accidentally touches Erika’s chest. Surprisingly, Erika doesn’t mind—she’s completely unaware of anything related to sex. From that day, their unconventional "intimate" life begins!
