If you liked the MM! anime, the Anime-Planet community thinks you'd like:
In a world where magic is a reality, the young Louise is at the bottom of her class. Dubbed "Zero" by her classmates at Tristein Academy (due to her zero success rate for magic), Louise (along with all first year students) was charged with summoning a familiar; and instead of a cute magical creature, the familiar arrived in the form of... Saito Hiraga, a normal Japanese boy who was abruptly teleported from his own world?! Can both Louise and Saito come to terms with their new and complicated "relationship" and (more importantly) help Saito find a way home?
It’s summer time, and even when they’re not at school, the students of Class 2-F are as idiotic as ever. With Akihisa and Yuji attempting to pick up girls at the beach and a simple trip to the festival turning into a cross-dressing beauty pageant, the holidays are proving to be just as stressful for the boys. But even back at school, life doesn't settle down. With Hideyoshi and his sister swapping places for the day, games of "strip doubt" after class, and academic training camps, it seems this semester will be just as hectic as the last.
Comedic violence meets hilarious dialogue, always a great combination for your laughing needs. And both of them contain a dosage of seriousness, not to overshadow the comedy of course. Throw in some fanatic cults, mind-numbing situations and craziness and you get an end result of either one of them.
Self-proclaimed, proud pervert Ryousuke loves women – to him, their butts and breasts are a 'treasure box' of joy for all men. So when the boy spots a fiery-haired girl standing in the rain one day, he invites her to his house – but he didn't expect to be stabbed with a magical sword in return! The girl, Lisara, is actually a high-level shinigami who must absorb the spiritual powers of others to survive in the human world. Until she can find a genius with enormous expendable energy, she's decided to form a contract with Ryousuke, but unfortunately for the busty babe, the horny teen's mojo is fueled only through his constant perversion. While looking for Lisara's true prize, the two must deal with other well-endowed shinigami and other foes alike, all while trying to maintain a 'typical' school life together.
They have a very similar feel.
The Male leads are perverts who have moral principals and go off on ecchi tangents. There is a Tsundere-ish female who is close to the male lead. Lastly, there is a shy girl who has feelings for the male who is a pervert.
Similar jokes and delusions.
After recovering from an accident, Hiyori has returned to school for the first time, and she's terrified! For Hiyori is painfully shy, and the idea of making friends, let alone introducing herself to the class, is impossible to bear. But regardless of her embarrassment, Hiyori's small stature makes her an instant hit with her peers, including the popular and attractive Yuushin. Confident or not, Hiyori's school – and love - life is just beginning...
Yeah, this one is a gut recommendation.
If you like Hiyokoi or MM! you may like the other. Both main character feel that their problem is preventing them from achieving their goals (Sado = Masochism, Hiyori = Shyness) and they're are both, essentially school-based love stories. The differences being, that MM! is more perverted and haremish, and Hiyokoi is more Shoujo. but if you like one you will most probably like the other
Ayumu was murdered by a serial killer – at least, he was. For after the mysterious Eucliwood Hellscythe revives him, he changes from a human to a zombie, much to his dismay. Now, in addition to being unable to die, the boy must see to the whims of his supernatural, silent companion – but things continue to get worse from there. As once Ayumu accidentally steals a magical girl named Haruna's powers, he is tasked with the embarrassing, obnoxious task of being a magical girl – err, boy – in her stead! Then with the addition of a hostile vampire ninja to his household, can Ayumu manage to maintain his new home life, fight against attacking monsters, and track down the person who killed him all while attempting to keep what little dignity he has left in tact?
Kore wa Zombie desu ka? and MM! are both about a guy in a weird predicament. They both are surrounded by girls with a variety of personalities, tsundere and sweet. The guy always is insulted, being called a pervert and is continously bossed around.
