Shabura ♥ Rental ~Ecchi na Onee-san to no Eroero Rental Obenkyou~

Shuuichi Odera, a stressed college exam candidate, ends up moving into the all-female dormitory of his sister's university. On his first day, he's warned to keep a low profile, but he's discovered by his sister's friends. Instead of reporting him, the girls decide to help him—because they all secretly long for a little brother. In exchange, Shuuichi becomes their designated 'little brother,' receiving both housing and study aid. This marks the start of his thrilling and risqué 'Exam Prayer! Brother Share (Rental) Life.'
