Taro Sado is a masochist. For years, this has left him unable to confess to a girl he saw at his job. At the advice of his friend, he goes to join the school's Second Volunteer Club. The first one is for normal volunteer purposes. The second is for personal problems and everything else. When he arrives, Taro meets Mio Isurugi, the club president with a sadistic personality, and Arashiko Yuno, a shy girl who's also part of the Volunteer Club. A masochist and a sadist meet, and Hilarity Ensues.Based on a series of 10 Light Novelsnote With the 10th ending on a Cliffhanger that will never be resolved, see Author Existence Failure in the trivia page, MM!, after a false alarm from the creators stating they wanted to be adapted into an anime in late 2007, was finally adapted into a Twelve Episode Anime in fall 2010.
Buxom Is Better: Played straight, subverted and inverted. Taro (and most other males) certainly notices Arashiko's "gifts", but at the same time Mio is still considered by many to be more beautiful, despite lacking horizontally. Inverted with Yukinojo, who very much does not like his beloved Noa using her special pills.
Camera Fiend: Michiru always has her camera at the ready to take shots of Mio's latest de-M-ing device or cute people in lavish get-ups. Especially cute people in lavish get-ups.
Catch Phrase: Arashiko's "I'm scared of men!" cry every time Taro accidentally touches her physically.
Becomes a plot point (as in literal fetish fuel) in episode 5. Specifically, Taro uses a piece of Noa's Mad Scientist tech to transform his perversion into raw power, effectively becoming a Super Saiyan for the duration of the episode.
Jerk Jock: Yoshioka. Hell befalls any girl that rejects him. Too bad his last victim turned out to have a "boyfriend" who's Made of Iron. And said guy managed to punch him out, leaving him for his last "girlfriend's" best friend to finish the job.
Knight Templar: The Mio Fan Club thinks that by hanging out with Mio, Taro will ruin her life. The club would use any methods necessary to get rid of Taro if it will maintain Mio's lifestyle in the way the club sees it. Thankfully they peacefully disband after Mio personally confronts them concerning her relationship to Taro.
Made of Iron: Thanks to his masochism, Taro has a very high pain tolerance. This allows him to hold himself pretty well when he is getting beat up by Yoshioka, who is an amateur kick-boxer, in Episode 3.
Magical Realism: The setting of the anime shifts more and more towards this as the story progresses. Unusually, most of the magical and sci-fi aspects of the story are fueled by the characters' perversions.
Out-of-Genre Experience: Episode 5's second half consists of an elaborate shounen action parody in which Taro foils a plan to turn the world into perverts using a Rider Belt and his own extraordinary perversion, which turns him into ero-Super Saiyan. Seriously.
Yumi is a subtle nod to Kenshiro: she's a practitioner and successor to a martial art style that causes pain and pleasure to her opponents with a single finger, much like Hokuto Shinken. She even assumes his Tenha Kasattsu stance when she is about to punish the girlfriend beating loser Yoshioka at the end of Episode 3. She also has a tendency to use Kenshiro's high-pitched Bruce Lee style Kiai when she rapidly strike the pressure points of her enemies with her fingers. Finally, her surname "Mamiya" also happens to be the name of the love interest of Kenshiro's best friend Rei.
In Episode 5, Mio dresses up as Louise with a wizard hat. The episode also features a Kamen Rider belt that turns the user into a Super Saiyan. Also, after all students in the school have been turned into perverts, there's a scene of two girls confessing their love for each other in a style nearly ripped straight off Maria-sama ga Miteru.
The opening of Episode 9 has Hatsune Miku and Black★Rock Shooter viewed from the back. Also, at the start of the episode, there's a very obvious color-swapped Miku holding an equally color-swapped leek, and a Ruri Dakimakura.
Taro's unchecked masochism is the most obvious example; he seems to feel his best option lies in a school club rather than seeking professional help.
A more serious case is that of Yuno. Her Attempted Rape left her so androphobic she can't even share a train car with men for fear of close contact, yet no mention of her getting professional counseling is ever made and she relies entirely on Mio and Taro to overcome her phobia.
