Garden: Takamine-ke no Nirinka The Animation

Tomoya is a high school student whose parents died in an accident during his middle school years. Since then, he has been living with his aunt Kasumi and her two daughters Ayame and Sayuri. Aya is the prettiest student at her school, but she has a little quirk: she’s always wearing her swimming costume! Sayuri is also an incredible beauty who has her own merits. The two girls have always treated Tomoya like their “little brother”.

One day, however, Tomoya gets drunk with his aunt and goes for her, much to her delight. Surprised by his unusual “masculine” manner, she wishes him good luck in scoring points with her daughters, too. He doesn’t need to be told twice with Aya, but Sayuri also wants a piece of Tomoya – to be more precise: his best piece.
