Motto! Yagai Gakushuu ~Kaki Tokubetsu Koushuu Hen~

Present day Japan. In order to help to improve the relations of their students schools are starting to organize summer camps.
In these camps the participants are required to be nude all the time to help them socialize and to get a better understanding of the opposite sex.

Shortly after the events of the previous installment Shouta and Itsuki talk about their adventures to their classmates.

Inspired by their envy Aoi, who is the daughter of a rich family, decides to organize a new summer camp. For that she also invites students from other schools who already participated in former camps.

This time the story focuses on Kanae, a nature loving boy whose hobby is to watch birds and who has trouble to socialize with others.
