If you liked the Mangirl! anime, the Anime-Planet community thinks you'd like:
Twenty year-old Mikiko Oguro (known as Kuromi to her co-workers) has just entered the dream job of a lifetime -- animation! However, upon her arrival to the famed Studio Petit, Kuromi is in for a surprise: her predecessor just quit, leaving her with the project, and the seemingly unattainable deadline! Now, with only a week left until the key animation is due, Kuromi must wrangle up the group of slackers who must finish Time's Journey 2 before it's too late!
Enjoy series that look behind the scenes of how anime/manga are created? Then you'll like both of these. While Mangirl has short episodes and covers manga, Kuromi covers anime and they both let the audience know those industries are tough places to work. If you enjoyed one, you'd probably enjoy the content of the other.
Both shows let's us view women going on about their daily job, which happens to be the entertaiment business. How to deal with artists, those oh so ominous deadlines and just how is an anime or an issue of a magazine made? These are all questions that might get answered in both of these shows.
If you are interested in the inner workings of the business, be sure to check out either work.
Moritaka Mashiro feels as if life is passing him by; with no dreams or motivation, he trudges through day-to-day life. One day, after leaving his notebook behind, he returns to school and finds the smartest guy in class, Takagi, waiting for him. Takagi is happy to return the book, but on the condition that Mashiro agrees to become a mangaka with him. Though Mashiro initially declines, he soon reconsiders when he discovers that the girl he likes, Azuki, dreams of becoming a voice actress. And after promising that she can have the lead role if their manga is ever adapted into an anime, he suggests that they get married once they are both successful! Shockingly, she agrees to the proposal and Mashiro and Takagi embark on their quest to become manga artists.
The anime have similar subjects. However Bakuman is deeper and goes on the mangaka side of things rather than the editors. It however is no way near as MOE as mangirl! So if you're expecting MOE look the other way as there is barely anything in Bakuman that fits MOE.
The students of the Geijutsuka Art Design Class study all the various fields of art, from sketching and painting to graphic design and photography. While the mischievous Noda is always thinking up new ways to have fun with her partner in crime - tomboy Tomokane - the ditzy Kisaragi is content with doodling cats in her sketchbook. With Namiko attempting (and failing) to keep the energetic duo in line, the quiet and mysterious Kyoujyu seems happy to observe the odd behavior of her classmates. Whether they are transforming a congealed lump of paint into a sculpture of a pudding, playing ‘color tag’, or making thought collages, the gang live their life to the max through both their friendships and their art.
Mangirl and GA have a similar style of comedy- silly and slightly spastic, as well as similar character types/interactions. Both are kind of about art (or the manga industry, which deals with art), and explore their topic with lots of humor as well as a slight educational leaning.
Ever wanted to join an anime club but felt its geekiness would hurt your reputation? Sasahara feels your pain. Genshiken, the Society for the Study of Modern Visual Culture, is an organization of college otaku obsessed with anime, manga and video games. Their daily activities include holding impromptu cosplay photo shoots, braving the crowds and avoiding injury at doujinshi conventions, and tolerating harassment by Saki, a girl irked by her boyfriend's otaku-ness! It's a perfect match for Sasahara's interests, so why is it so difficult for him to join?
Both are otaku related products and both have information on making manga. Genshinken however is deeper and the characters are somewhat more realistic. While the casts presumably have about sbout the same age the anime have greatly differing characters. Mangirl! following character tropes far more closely
Fumihiko Matsumaru is a salary man who works in the marketing department of a snack company. As a bachelor, he tried to date a girl from his company; but coincidently, he met Aka Onda, a rookie voice actor, instead. Through another stroke of fate, Aka’s house burned down that very night. With nowhere to stay and no family to aid Aka, Fumihiko took her in; and the next day, Fumihiko’s new marketing idea was accepted, and Aka’s being hired for the product’s voice actor! As the relationship of Aka and Fumihiko deepens, the more difficult their relationship becomes. Can they live together under the same roof while keeping the secret of their relationship safe?
If you're looking for another super short series about characters' careers (especially focused around the entertainment industry, like voice acting or manga production), look no further! Rec is intended for an older audience, and has less hyper comedy and more romance than Mangirl (I found Mangirl pretty annoying, to be frank). However, if you like slice-of-life series about characters that have jobs, instead of ones in high school, both may appeal to you.
