If you liked the Plastic Nee-san anime, the Anime-Planet community thinks you'd like:
What do you do when the Emperor of Japan has been replaced with... an alien from Planet Octopus?! From intense motorcycle races to crazy machine inventors from Holland, from sea voyages to battles about emo trading cards, there's never a dull moment in the life of the bizarre. Join an eclectic cast as they are visited by a Ramen Fairy, are reincarnated over and over, solve cases like detective pros, and overall have a laughably ridiculous time!
Both these series are random comedy. Plastic nee-san has a consistent cast of characters where as Gag Manga uses many different character both show rely on short energetic sketches to keep the audience laughing. Both show are fairly funny if you like random humor. Gag Manga is the funnier show but if you liked one of these then you should check out the other.
In present day Japan, the life of a school girl is never dull. The easily-bored Konata never finds time to study because of her otaku habits, which frustrates hard-working Kagami to no end. On the other hand, laid-back Tsukasa always manages to go with the flow, while Miyuki is concerned with keeping her status as resident know-it-all. Join these four girls as they muse and meander their way through everyday events such as eating chocolate cones, doing homework, gaming, and trips to the beach galore.
Both series follow the antics of a group of Highschool girls. Both have a random sense of humour and neither of them have an actual plot. It should be noted that Plastic Nee-san's humour is a bit more crude than Lucky Star's humour. Also, Plastic Nee-san has episodes that are 2 minutes long while Lucky Star's episodes are the normal TV length. Still, if you like one, you will probably like the other.
Mayu learned everything she knows about manners from her mother – most importantly, that in any conversation, she should make eye contact at all times and let the other person finish their thoughts completely before responding. Unfortunately for Mayu, this advice is difficult to follow when your friends are a bunch of talkative high school girls, and has left everyone thinking she's overly quiet and shy instead! With good friends such as chatty Miki and shy Hana beside her, Mayu will silently navigate her high school life and have plenty of fun in the process!
Both series are about girls at school being very random and funny. They both have short episodes as well so they get their quirky "plot" to the point right away. Plastic Nee-san is a little more out there than Morita-san but if you enjoyed one you'd probably like the other
Wakame High School has its fair share of weirdos, and transfer student Fumiya "Fuumin" Okometsubu is about to meet the strangest one of all. Planning to make one hundred new friends, the first to step up to the plate is Masaru Hananakajima. Becoming an unwilling student in Masaru's secret martial arts style, the two embark on enrolling more unsuspecting victims to learn the "Sexy Commando" way of fighting. Recruiting Kyasharin, the feeblest strong man in the world; and Kondo, the aspiring manly man; the group embark on a voyage of moronic triviality. From an outrageous sleepover to playing the baseball Game of Honour, the team must finally pull together and remove their pants for the National Sexy Commando Tournament!
Funny short comedy sketches with a crazy cast of characters. Both of these show use random humor and bizarre situational comedy. The characters are zany and the situations are as random as they come, but they both use this to their advantage to create some hilarious scenes. Both shows can be a bit hit or miss but when the jokes land their quite funny.
