I've just finished Ao No Exorcist and I'm looking for something similar to that. I'd like to watch an anime where the main character has a secret that he has to keep from other people, and it would be great if he was still in school. I've really enjoyed Kuroshitsuji, Attack on Titan, and Guilty Crown.

I've also watched Fairy Tail, Death Note, 07-Ghost (didn't like that one much), Hataraku Maou-Sama, Another, Pandora Hearts, Vampire Knight, Free, Angel Beats, and Shigofumi.

It would be great if someone had a recommendation! I like the art style of Attack on Titan and Kuroshitsuji, as well as the music.
