Tokyo Ghoul (Season 1)

Tokyo Ghoul is originally a manga series written and created by Sui Ishida that became a television anime series in 2014. The season consists of only 12 episodes but worry not, it is action packed all the way to the end. This is also definitely on the bloodier/gorier side.. there is really not much comedy or romance. The plot is interesting with full of human/flesh eating ghouls (instead of the usual vampire or werewolf stories) with a good vs evil type of theme. The main character's name is Kaneki and he is a half-breed of human and ghoul which brings a lot of attention to him throughout the anime. 

I thought that I wouldn't like this anime due to the gore and blood (and how short it is) but it actually has a really interesting and twisted plot to the show. I haven't seen anything similar to this yet and I was hooked after the first episode. I recommend it for sure, but if you're not into flesh eating monsters then I advise you to stay away.
