Kateikyoushi no Onee-san 2

In this anime, we see the continuation of the studies of a guy named Toya-kun, who spends the summer in the company of female mentors. They know how to interest a guy so that he can assimilate all the information they are trying to convey to him. What will these girls do to attract his attention? Obviously, they will use their attractive forms while being in the same house with a guy.

On the other hand, the guy sometimes spies on the girls' conversations and their activities in the rooms, and, of course, his interest in watching them does not go unnoticed. There's always something going on...
