Ansatsu Kyoushitsu

Teaching underage children to kill things... Underage violence in general. That's always fun. Also, great character designs and unique plotlines. The humour is another bonus.

Donten ni Warau

The villains are snake-y. Pretty action-based. Happy smiley protags. And face it... If you still like Naruto, you need new anime.

Tokyo Ghoul

Character death everywhere. They'll both rip your heart out. 100/10 would recommend if you like hurting yourself. Also, anti-establishment themes if that's your cup of tea.

Makai Ouji: Devils and Realist

DnD is the Walmart version of Kuroshitsuji but it's still a pretty great waste of time. Also: Dantalion.

Both produced by Madhouse. Psychological and thought-provoking themes.

Ore Monogatari!!

Shoujo manga tropes, ridiculous characters, and pairings that you can actually root for. Not a huge shoujo fan myself, but I love both. Characters are extremely lovable.

Owari no Seraph

Supposed sexual tension between blonde and dark-haired protagonists. Apocalyptic themes. What's not to love?

Arslan Senki (TV)

They've both got an almost 'Game of Thrones' sort of feel. Also, Arslan Senki is made by the same author as Full Metal Alchemist.
