Seeking a cure for his depraved masochism, Taro Sado approaches the Second Volunteer Club on the recommendation of his best friend, Tatsukichi. There he finds the help of the violent but kind Mio Isurugi who promises to beat the masochism out of him by any means necessary. Will Taro be able to survive the assaults of this upperclassman, the overly-affectionate attentions of his mother and sister, and still lead a normal school life? Unlikely. But will he get over his perverse fetish? He sure hopes so.
Keitaro Urashima is somewhat of a failure. In order to fulfill a promise he made to a girl fifteen years ago, he has tried time and again to get into Tokyo U but has never managed to pass the exam. However, fate smiles upon him and he ends up working for his aunt, managing an all-girls dorm! Living with the feral Kaolla, the timid Shinobu, the sake-loving Mitsune, the blade mistress Motoko and the punch-happy Naru, can Keitaro keep his focus and keep his promise? And will he ever end up meeting that girl from his past?
Having lived in the same orphanage as children, Takumi Tsuzuki and Fumino Serizawa grew up together and remain fast friends. Now living and working at a bakery, Takumi does his best to prevent catastrophe, particularly when the clumsy Otome is in the kitchen! He attends school with Fumino and is still the only person capable of reading through her baffling habit of hiding her emotions by saying exactly the opposite to what she means. However, the arrival on the scene of enigmatic catgirl Nozomi may force Fumino to be more honest with her feelings than she is used to - or perhaps even able to. This, along with a host of crazy friends and associates such as the stuck-up Chise and the otaku Ieyasu, ensures that there is rarely a dull moment in their lives!
The main similarity with both anime is that the girls all like the main guy, but the guy is clueless about it. With some not honest with their feelings and others very open about it, it is very hard for even the viewers to choose who he should be with. Also, another similarity is that the main character keeps getting hit by the tsundere girl, only in MM! he enjoys it more.
If you liked MM! then there is a chance that you'll like Oniinokoto (and vice versa). Both feature a cast of unusual characters and don't hold back on sexual allusion, definitely not one for kids. Another comparison is the cast's habits, all of them are unsual and not usually seen in recent animes. Overall how ever Oniinokoto seems like it will be far more ecchi than MM! but both seem to be worth watching. So if your in the mood for some different why not watch either one of these?
Kyousuke Kosaka is a normal teenager with average grades and an average home life, but when he finds out that his overachieving younger sister Kirino has been hiding her vast anime and eroge collection from their unassuming parents, his world turns inside out! Now, having promised to help his formerly distant sibling navigate her two distinct lives, Kyousuke finds himself drawn into Kirino's world of magical girl anime and "little sister" fetish games while covering for his sibling to her parents and friends, not to mention trying to provide what guidance he can.
Both are comedy anime and the female leads are tsundere characters with blue eyes and blond hair, they even have the same seiyuu. If you haven't seen Ore no Imouto yet then I warn you that Kirino (the female lead) is extremely annoying in my opiniom throughout the whole series.
At Ina Middle School, the boys’ Ping Pong Club is seen as more of a joking matter than something worth the school's budget. It doesn't help that they are constantly being outdone by the girls' team and their fiery-tempered coach, as well the fact that most of the boys on the team care more about their ding dongs than their ping pongs! In a desperate attempt to motivate the team, the boys' coach introduces a hot-bodied female manager, who might just bring a sexual tension to the team that could work to their advantage. But can these hopeless boys improve their game enough to emerge victorious at the upcoming tournament and win the prize she's willing to give?
The main thing Ping Pong Club and MM have in common is shameless, outrageous, perverse comedy. Both shows are about clubs that are loaded with bizarre people. MM is somewhat more tame than Ping Pong Club and actually has some slightly serious elements to it, not to say that MM is a serious show. Both of these shows are really funny if you are not easily offended. If you like the humor in MM then Ping Pong Club is worth a try and vice versa.
