Komine is a bar that is worshipped as the "god of virginity" and where virgins from all over Japan come to Tokyo to have sex. Located in Suidobashi, Tokyo, the bar looks like an ordinary bar from the outside. The bar's Hinata, Hinata, is a rare beauty, with overwhelmingly large breasts and an overflowing maternal love. She offers alcohol and listens to the virgins' selfish requests, sometimes violently, and turns them into full-fledged men.
