A current anime that is airing currently and easily the best show of the season: Noragami
Plot Summary: Yato is a minor deity who lacks even a single shrine. In order to build his own shrine, he scrawls his cell number on the wall of a downtown bathroom telling people he will help them in exchange for a 5-yen offering, becoming a self-styled "delivery god." Hiyori, the daughter of a respectable family, is almost in a traffic accident, but is rescued by Yato. This causes her to become a "hanyou," a person who can easily lose her soul. She chases Yato down, and they begin to work together. Yato also finds a boy named Yukine who becomes a "sacred treasure" that can be used by a god. The three of them battle "you" who bring harm to humans as Yato's hidden history is gradually revealed.
This show so far with 10 episodes in is dark but funny (mixes both brilliantly), has fantastic anomation quality (would expect nothing else from studio bones), one of the best soundtracks i have ever heard and likeable set of characters that get all the backstory they need to be likeable
