Midara na Ao-chan wa Benkyou ga Dekinai

Both are love comedies. Both main girls have dirty minds!  

What happens when the father of a pure daughter makes dirty mangas for a living? Well, Kakushigoto and Midara na Ao-chan are both into the same business that the father is a famous ecchi mangaka, however, in Kakushigoto, the mangaka dad hides to his daughter his actual job, while in Midara, the father openly says that he draws ecchi manga. The daughters are pure, but different, Hime is 10-11 years old in most of the story, and she's oblivious to what his father does for living, Ao is completely aware of her dad and his colourful mangas, due to her age (18), she's already psychoed by her father's "advices" on literally everything. The biggest difference is that in Kakushigoto is only limited to the father-daughter relationship, while in Ao-chan Can't Study that role takes a second seat and focuses more on the potential romantic relationships for Ao. read more 

Sex Sex Sex seitokai is infamous for its out of context shots of innuendo humor and midara has got something similar going sekotai is alot more relaxed tho were as midar is more rom comish both fun series  

Both are comedies that somehow revolve around sexual repression. Also, in these full of ecchi shows the protagonists' fathers are both very known "perverts". 

The protagonists of both animes try very hard to suppress their sexual desires and they deny that they're down bad because of trauma relating to their father's reputation but they're unable to resist sexual desires and eventually would cave in. The lead girls of both also look very similar. 

Both girls have to face some funny or troublesome situations regarding the opposite sex. 

Both have that the same romance between a popular hot person and geeky perosn, except in 3D it's more like a hot girl to geeky guy , while in Midara na Ao is a geeky girl to hot guy. 

Rom com where the girl is the one who is obsessed and is trying to make moves on the guy but misunderstandings cause a lot of awkward but funny situations much to the girl's chagrin. 

Both shows feature female MC's who are initially reluctant to engage with boys romantically, however, through the persistence of the male lead they begin to soften up their initial opinion  

Obviously, in both anime the characters have trouble studying. Besides that both anime are generic teen romance anime with some comedy. Differences are that in Midara Ao most of the comedy is ecchi, while on the other hand Bokutachi is a harem. Is it really coincidence that there are 2 anime with pretty much the same name airing during the same season, or does Japan just lack creativity? 

If you like Mamaha's aspect of showing the female heroine's perspectives and thoughts regarding her romantic situations then Midara na Ao-chan wa Benkyou ga Dekinai is an anime I would suggest checking out. Although their plots are nowhere near similar, the heroines are really good at creating exaggerated fantasies about their male love interests, which is funny in its own unique way. 

Both anime involve girls exploring their sexualities while also having really cute scenes and flushed MCs. While Ao-chan is obviously pandering to male viewers by being over-the-top sexual, Arabaru treats its' sexual themes as social commentary and is directed more towards female viewers who might relate to each MCs situations. If you're looking for the similar theme of girls exploring/ succumbing to their sexual nature (while executing it better), Arabaru is for you. If you liked the fan servicey scenes and want somethng like that, go watch hentai idk lol
