Rioka is an active university student who attends the famous National University. She came home during the summer vacation after a huge break with a healthy body trained in swimming. The swimsuits are very sensitive and irritating when the trails of swimming bathing suits are crisply burned down. Rioka, who said he had a hard appetite, hit him with all the eros in his summer camp. "Sports girls are very elois," the rumor seems not to be a lie.
