## Description
The long break is over, and the protagonist’s new semester has begun. For some reason, Leviola and Milis were right by heis side as he headed to school.

“We’re worried about you, Yuu-chan, so we’re going to tag along with you♪”

Believe it or not, the two of them had decided to attend the protagonist’s school, one as a student and the other as the school nurse.

“Good job making it to school!”

“Good job making it through the first period!”

“Good job making it through class until lunch break!”

And so on… They kept coming up with excuses to give the protagonist one naughty reward after another. Thus begins the protagonist’s incredibly naughty school life with his devilish older sisters.
