Summer break has come for the prudish virgin Kouta Oyamada and his friends. For Akane Asahina this means trips to the library, while for wolf-spirit Nozomu this means sleeping naked in a hot apartment or bathing in front of Kouta's house. Unfortunately for Kouta, summer brings with it Chizuru's racy morning exercise regimen and noodle eating in the buff. How is he supposed to get any homework done in these conditions? Whether it be catching bugs for food, creepily shooting video documentaries on their classmates, dropping in from the mountains to visit family or just going to see fireworks, the gang’s summer will be far from relaxing - and in various states of undress.
