It is the season of summer.

The protagonist has failed to clear his college entrance exams for the 2nd time. His parents forced him to enroll at a live-in prepatory school in countryside. Run by his elder female cousin, the protagonist visited the school "Shooting Star Garden".

However, it was a girls-only dormitory.

A brave girl who aims to get into university while fighting a disease,

A girl who was hurt from failing to appear for her exams,

An old fashioned girl who swings a sword,

A sexy elder cousin and a friendly younger cousin.

What will become of his life, living with these various heroines?
