Taro Sado is a high school student who lives his day to day life with a big secret—he's a masochist! Encouraged by his cross-dressing best friend Tatsukichi Hayama, Taro asks the Second Voluntary Club for help with his problem and ends up joining the club after they vow to "fix" him. However, it turns out that all of the members of the club have some serious issues. The club leader Mio Isurugi is a self-designated god who is afraid of cats, Arashiko Yuuno has a severe fear of men, and the club advisor Michiru Onigawara is a sadist who enjoys making people cosplay. Together with other wacky characters such as Yumi Mamiya, a talented masseuse and Yuuno's best friend, and Noa Hiiragi, the president of the invention club, they all learn about the importance of acceptance and kindness. There are twisted tales and twisted tales, but few are as twisted as poor Sado's, who's just realized that he actually likes being made miserable. Of course, knowing that only makes him more miserable, which in turn... well, you get the idea. Desperate to break the circle, Sado volunteers for a special club where he hopes he can work through his issues only to discover that the other members have equally... complex... issues to deal with.
