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.
Kenji likes to think that he and his gang of friends are the bad boys of their school. That is, until he meets the four insane girls of a game-making club whose personalities are all super weird (and a little on the violent side). When Kenji’s forced to join their little group, his life quickly takes a turn for the outrageous.
These are both wacky school comedies about a group of misfits in an after school club. They both start when an outsider enters the club and stirs things up with their presence. Both shows feature a lot of parodies both of other anime as well as pop culture in general. Both anime have a cast of eccentric characters with funny quirks and a lone straight man that seems like an island of sanity in a crazy world.
MM! is primarily an ecchi comedy so most of the humor tends to be rather perverse. D-Frags comedy is more broad, but it has its fair share of perverted jokes as well.
MM! has much better comedic timing and the editing is much tighter while makes it a much better comedy. D-Frag does have a lot of funny moments, but the editing leaves them feeling a bit lacking. However, if you enjoy school life comedies with a heavy parody aspect then try both of these shows.
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
