If you liked the Moyashimon anime, the Anime-Planet community thinks you'd like:
With a history of leading a motorcycle gang and getting bad grades in school, why would 22 year old Onizuka ever want to become a teacher? Is it to educate young minds or spread the joy of education? Sure, if it involves being able to look up high school girls' skirts! Watch as this would-be educator uses his own life lessons and unconstituted methods as a means to control a delinquent class of students -- students who certainly aren't as happy to have him as a teacher as he is happy to be teaching...
Silly humour combined with some interesting characterisation is the core of both these anime. If you liked that angle in Moyashimon, where it uses a range of bizarre situations to try and explore some quirky characters, then GTO should satisfy on a bigger level. The premise is just as unbelievable, the characters explored in more depth, the protagonist is sillier than ever, and there's ecchi and lots of tomfoolery. You can't go wrong.
On a day like any other, average middle-school-student Yurie Hitotsubashi got the surprise of a lifetime – she became a goddess! Unfortunately, even with her newfound powers, Yurie still can’t manage to find the courage to confess to Kenji, her crush. With Yurie’s fame comes others’ fortune; Matsuri, caretaker of the local shrine, names Yurie the shrine’s new goddess and becomes her manager – for yen and glory! Along with Yurie’s faithful best friend Mitsue, the trio set forth on an adventure to find out what it really means to become a goddess.
Moyashimon and Kamichu! are two of my favorite comedy/slice-of-life series. They're light-hearted, silly, easy to watch, and have much more unique characters and situations than most shows in the genre. Both are about a character that can see and do things that others cannot, and how they deal with that power.
Are people really defined by their blood types? A, B, AB and O-Type are here to set things straight. Whether they're trying to cross a bridge, sharing their hearts or meeting aliens, the four blood types continue to prove – or disprove – popular theories about themselves. Does B-Type like rules to be broken, is A-Type cautious and naïve, and is O-Type a peacemaker?
If you like the microbes' antics in Moyashimon, you'd probably appreciate the personified blood types in Ketsuekigata-kun. The series fits better with Moyashimon's shorts, but would appeal to fans of the main series as well.
Yukitaka has just left Tokyo, eager to transfer to Kisaragi High where he's been recruited to play baseball. However, upon entering his new apartment, the boy is met by a man with long blonde hair who claims to be… an alien?! After initially scoffing at the notion, Yukitaka discovers that the alien – Ouji – is for real, has amnesia and, what's worse, now wants to live with him in his apartment. The fact that scientists and mysterious guys in black suits are after Ouji becomes the least of Yukitaka's problems as his new guest turns out to be more than a handful to handle!
Level E is a decidedly eclectic show whose comedy leans heavily on the whimsy of its self-centred protagonist, the Prince of Dogura. In making this recommendation, I was trying to remember the last time I had this enjoyable 'taken along for a zany ride' feeling, where amusement requires casting suspension of disbelief to the winds. And Moyashimon immediately popped to mind. Their narratives and setting have nothing in common, and Moyashimon's humour is a little more elusive, but they give a very similar eccentric experience.
Natsume is lonely; he has an ability that separates him from others: he can see and interact with spirits. Soon, however, Natsume discovers that he’s not alone: his grandmother Reiko also had the gift. But things get hectic and possibly dangerous for Natsume when he finds out that he also inherited the 'Book of Friends', a book that contains the names of all the spirits Reiko defeated and subjugated. He finds himself hounded by his grandmother's underlings and, with the help of a 'cat' charm spirit, decides to free them from the Book's shackles, as well as protect the book from those who seek to misuse its power...
In both animes, the main character is able to see things normal people can't.
Moyashimon focuses more on comedy and Natsume is in my opinion far superior in both story and art, but both are worth a watch.
