Quickly meeting the famous scientist Galileo Galilei, Marika is introduced to science in a whole new way. The town, Galihabara, is home to a number of notable inventors and tinkerers including Newton, Edison, Marie Curie and even Leonardo da Vinci! However, these ordinary figures of history are anything but - from MCs to ramen shop owners, each scientist is definitely unique in their own way. Alongside her magical stuffed animal Pet, Marika and Galileo explore Galihabara, learning important lessons along the way!
Tsuchida has just started working at the Hanamaru Kindergaten, and, as the first and only male teacher at the school, he’s particularly nervous. Unfortunately his first day doesn’t go quite as smoothly as planned as not only does Tsuchida turn up late, but then a small girl named Anzu claims that he hit on her in front of all the parents! Though he manages to initially clear up the misunderstanding, at the beginning of his second day, Anzu proclaims that she will be his bride and that her mother, Tsuchida’s senior in high school, is supporting them all the way! Now as Tsuchida attempts to become the best teacher he can be, he must also try and quell the rumors that he is dating Anzu, and maybe win the heart of the beautiful and kind, yet ultimately clueless, Yamamoto-sensei…

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.
Ai, Mai and Mii are three would-be manga artists who can't seem to stay out of trouble, let alone complete a project! Whether they're having a one-off encounter with the forest dweller Yamu, becoming human sprinklers, entering manga battles or entering a doujinshi fair, the trio have fun one day at a time.
Both series focus on art (or in Ai Mai Mii, manga), but with a cutesy and comedic fashion. Both are heavily moe, and feature high doses of randomness. However, GA has some information put into it, whereas Ai Mai Mii does not.
In either case, if you liked one, the other may be enjoyable to you!
