Balance unlimited is a very fun watch for me, and it has a lot of good things about it The story starts as a normal police show that is quite shallow, but its not very annoying because the characters are fun to watch and the soundtrack and art are very good. From episode 6 it gets an actual plot which is super intriguing and easy to get invested in, the characters also become a lot more fleshed out and I really liked that :) all in all I would definitely recommend you give this anime a watch, and see if you like it
