Synopsis
This world is a bug. It looks like it goes back and forth between adults and little girls depending on the day. There is also a period of growth. "Naoya Hachiga! Join my committee and save the 'abnormal' together!" This senior who calls himself Sodemori seems to have a bug in his head. In the first place, I have no time to do so because I am in danger of dropping out. Ushi! Don't ponder. Because I'm a super A-class "abnormal" who freezes when I think about it. In a world that has become buggy, youth romantic comedy with "defective beautiful girls" starts.
