The naughty girls from the comedy hentai movie Megami-ryou no Ryoubo-kun part 5 who live together with young boy Koushi Nagumo in the women’s dorm are going on vacation during summer break. The classmate of the boy, the redhead schoolgirl Sutea will join them too. But the sexy blonde girl Serene thinks it’s a bad idea. As a dorm mother, Koushi has to solve this problem and figure out what’s wrong with the girl. Serena can’t move because her anime activites are limited to the dormitory and the college campus. She has never set foot outside of this area, so there is a sense of unease. The moon’s power abounds in this vicinity. Her friends have to find some potential segments, as Serena calls them, and give them to her as a gift. In other naughty words, they’ll be creating a portable safe zone that she can carry with her even on a hentai movie trip.
