The leader of the tennis club, Kaori Kitamura, was forced into a vicious sex group. When Kaori had to choose between going to an important tennis match or meeting up with Ami and her friend with benefits, she chose the latter. Ever since that day, Kaori dropped off from being the top player in the club. She skipped her training and kept having sex every day. Nozomi, the vice leader of the tennis club, and Seiya, Kaori’s boyfriend, are worried sick about her. One day, the soccer club asks for a favor for Kaori to come to the training camp as a helper. Nozomi talks to Seiya who is aware that things can’t keep up like this. As a result, Kaori becomes an attendant during the soccer club’s summer training camp. However, it turns out that the soccer club has a dark tradition that makes the training camp a malicious place.
