Kodaka is a delinquent. At least, that’s what his fellow classmates seem to think. Thanks to his naturally-blonde hair and an unfortunate series of misunderstandings, the boy can’t seem to shake his false reputation and hasn’t made a single friend. That is, until one day he overhears the normally-aloof Yozora enthusiastically chatting with an imaginary friend, and discovers that she’s just as lonely as he is! In an attempt to finally meet people the duo decides to form the “Neighbors Club”, and are soon joined by a number of other fellow misfits such as Sena, the busty, popular daughter of the school president who can’t seem to connect with others. Together, the gang learns about the joys of friendship through many misadventures such as playing RPGs, visiting the swimming pool or even hunting down delicious takoyaki!
Boku wa Tomodachi ga Sukunai reminds me a lot of Rosario to Vampire in the sense that the male protagonist is in search of friends in a new school. Both shows are centered around school life and full of comedic moments, but Rosario to Vampire focuses more on action and romance than Boku wa Tomodachi ga Sukunai does. You can expect otaku references, laugh-out-loud moments, ecchi scenes, and even tons of moe in both shows as the male protagonists tries to live out a normal everyday school life.
Manaka Junpei is an average guy who has only two dreams in life: to become a filmmaker and to find the girl of his dreams. Luckily for him, after a chance encounter on the roof of the school, he has a lead on the girl! She was wearing strawberry panties. Unfortunately, he can't figure out which one of the five girls chasing him it was; but he gets plenty of chances to find out the color-of-the-day in his Cinderella search for his one true love!
Both are well executed high school harem comedies with the male leading being a lot more likeable and less perverse than most. Ichigo is more realistic and dramatic, while Rosario is more supernatural and comedic. Ichigo is the superior show by far, but if you found one entertaining, the other will probably satisfy as well.
Ten-year-old genius Chiyo, animal-loving Sakaki, loudmouth Tomo, athletic Kagura, weight-conscious Yomi and dim-witted Osaka are six friends who share laughs, good times, and a high school homeroom. With scary (and sometimes perverted) teachers, school festivals, penguin suits and general hilarity abounding, you can be sure that there's never a dull day in the life of one of these students!
Why these two when Rosario is clearly more ecchi than Azumanga? Well, because Azumanga parodies the ecchi school girl anime (see Kimura for reference), and because both of these animes are a lot of fun. While Rosario has a bit more fighting and drama, Azumanga is not without its share of hilarious action. School trips, girl geniuses, and mentions of breat-size float between these two animes.
While visiting his hometown, junior high school student Michishio Nagasumi's life was changed forever when he nearly drowned. Though he was saved by a mermaid named San, there’s a catch -- her family is part of a merfolk mafia, and they abide by a strict rule: If a mermaid is discovered by a man, either he or the mermaid must die. That is, unless the man marries into the family! Faced with such a decision, Nagasumi can only oblige their customs and become a "happy" newlywed. Now, with a new school year around the corner, Nagasumi must find a way to deal with his new bride, keep her true nature a secret, and most importantly, escape inevitable death at the hands of San's over-protective father’s gang!
Both of these anime involve a boy that gradually finds himself surrounded by supernatural women. The main girl is rather ditzy until she has to defend the people she cares for. With others vying for the guy's attention, school life, and trying to keep the girls' powers a secret, these anime are pretty similar.
