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 Novels*
With the 10th ending on a Cliffhanger that will never be resolved, see Author Existence Failure below
, 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 12-Episode Anime in fall 2010.
Attempted Rape: How Arashiko came to not like men in the first place.
Attractive Bent Gender: Tatsukichi whenever he crossdresses. Now, also Taro in episodes 8 and 12.
A Twinkle in the Sky: Happens to Tatsukichi and Taro, who get it from different girls (Mio kicked Tatsukichi; Arashiko punched Taro).
Author Existence Failure: Sadly, Akinari Matsuno passed away shortly after publishing the 10th novel, which ends on a Cliffhanger. The manga artist, Hyouju Issei, will likely continue the manga using the novels as a basis.
Bitch in Sheep's Clothing: Mio appears as cute as can be when Taro first meets her, but that facade is pretty quickly stripped away ten minutes into the first episode alone.
Blue with Shock: Taro's reaction when he sees his sister Shizuka enter the beauty contest. Followed with a Color Failure when he sees their mom Tomoko follow suit.
Bromantic Foil: Tatsukichi seems this to Taro, though subverted since Yumi likes him.
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.
Cliffhanger: The 10th (and final) novel ends with Taro being confessed to by Mio, when he is already in a relationship with Arashiko. By this point in time Noa already confessed as well.
Michiru takes it much further, being an actual sadist, while Mio is merely a rather violent tsundere.
Cosplay Otaku Woman: Michiru has costumes for any occasion, and will dress people up in them just so that she can take pictures of them in her get-ups.
Noa is extremely maladjusted thanks to Child Prodigy exploitations during her childhood, and definitely has a complex about her appearance.
Yukinojo, Noa's pedophilic admirer, goes on a rampage whenever he senses she decides to use some growth pills that turn her into a lady befitting her age.
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.
Foot Focus: Some of it comes up here and there; the most prominent one being in the show's introduction sequence.
Yuno and Taro get on these terms with each other in Episode 2. But it turns out Taro didn't fulfill his end of the bargain. And Yuno is using it as a way to get around her androphobia... because that's also the name of a dog that she used to own.
Mio doesn't quite realize that she called Taro by his first name for the very first time in Episode 11. She also calls his name out in the last 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.
Love Dodecahedron: (Sort of?) Tatsukichi, Yumi, Noa, and Yukinojo could probably fit in there somewhere. Taro had a crush on Tatsukichi's alter ego until he found out that Tatsukichi and the alter ego were one and the same. Yumi showed interest in Arashiko,but also Tatsukichi. Yukinojo likes Noa, who in turn likes Taro.
Lover Tug of War: Episode 4. Arashiko << Taro >> Mio. With real tug ropes to boot.
Love Triangle: A potential Type 3, or possibly Type 7, with Mio and Arashiko both showing interest in Taro. Granted, Taro is probably happy to be with any girl who will satisfy his masochistic urges, but only Mio and Arashiko seem to have deeper feelings for Taro (or vice versa).
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.
Ominous Latin Chanting: Ominous chanting of some sort serves as Taro's leitmotif when he's having powerful masochist moments.
Once per Episode: Mio trying some new torture method on Taro to "cure him" usually involves her dressing up, thanks to Michiru-nee-sensei, natch.
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.
Panty Shot: Completely averted. Even with such load of fanservice and ecchi, and even more "shotty" scenes, not a single one occurred to viewers. ... Until episode 12, that is. Mio saved it for Taro's Christmas present.
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.
Split Personality: If Tatsukichi is called "beautiful", he slips into an ojou-like personality that praises himself and damns everyone else. Especially Mio.
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 them 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 (this is justified, however. See Values Dissonance in the YMMV tab).
