Sado Tarou suffers from sexual masochism; he experiences sexual pleasure from pain. He feels he won't ever have a normal relationship with his condition and decides to visit the Voluntary Club, a place that grants students' wishes, for a cure. At the club, he finds Isurugi Mio, a girl who thinks she is a god, and Yuuno Arashiko, the girl who caused his condition in the first place...
MM! the anime
A great and funny anime with many heartwarming parts as well as funny parts. If you find fetishes like S & M creepy like me, you may be a little disturbed. However this anime has so much humor and plot to it that it's easy to overlook such small details. Love the anime but i found the last episode to be quite lacking in terms of romance being settled. However I expect a season 2. This anime is definitely an anime worth watching if you want to laugh.
A show about a boy who is a masochist and goes to a club for help to cure himself, it is just a joy to watch. Everything is reasonably reasonable... It's cute and funny. I'd rate 6.7/10 well over 5 so worth watching. It's a cut loose show, i took off points for character design, plot/ecchi, and a bit for romance/action/comedy/mystery etc. The hole for plot should be filled with ecchi or comedy and since its a harem there should be romance or at least blush scenes to compensate, but they stuck with the masochist thing all the way through lol.
Masochist shows are far off from ecchi, there is no other show i can suggest. Try greengreen or seikon no qwaser, no maso but some good ecchi at least.
