Aw, this like, died D:
Durarara!! is a mix between "slice of life" and "fantasy" genres, which is sort of strange, but it really does work out - the creators did such a fantastic job with it. As Sanaka said, it's very much worth your time C:
Basically, it's a group of friends who are like, best buds, but in reality they hardly know each other at all. Mikado, the main character (sort of, between him and Celty), comes to Ikebukuro at his long-time friend's request so that they can attend high school together. Mikado has never traveled much in his life (skipped field trips and everything), so it's a HUGE first step for him - however, he trusts that it'll go well because he's with Kida, his best friend.
It's basically about gang wars in the city, the rise of a new gang, Dollars, and a dullahan trying to find her lost head C:
Of course, there's so much more to the plot that you just totally have to watch it to grasp it all.
It's one of those shows that's so amazing in a way that's so hard to define. Watch it, it's almost certain you'll enjoy it to some extent ~
