 If you liked Ansatsu Kyoushitsu |  ...then you might like Boku no Hero Academia 3rd Season |
Both set in a class Both use all characters in class and theyre really good
Both anime revolves around students in a certain class. Also, I think the personalities and friendship between Nagisa and Akabane in Assassination Classroom is kind of similar to Midoriya and Bakugou's in My Hero Academia. Nagisa and Midoriya being the subdued, observant guy who used admire close friend. While Bakugou and Akabane being the seemingly brash and delinquent guy that actually quite smart and tactical, and both pushed the person who used to be their close friend away after they realized the said friend is actually not really the weak guy they thought before.
