- Rimu, a younger sister who uploads a radical cosplay costume to SNS and seems to be calm even if she exposes her naked outfit to satisfy her desire for approval, saying, "I'm going to have a demon buzz and my sense of beauty will increase when I see it." Even at home, my sister who wanders around while shaking her huge breasts in an exposed costume that almost exposes her boobs is noticeable, while I am careful as an older brother, but I unconsciously look at it with unpleasant eyes ... - I exploded with irritation and at my cheeky sister who didn't listen to me, and I forcibly pushed my sister down as a punishment and made her understand that I was vaginal shot with a milk rubbing so hard that the nipples came off.
