Well, this is spoilerish, but since it will become clear in ep1, I guess I can sum it up. Please do NOT read the spoiler unless you already know from the manga, or you REALLY REALLY want to know. Otherwise wait for anime ep1.

Spoiler for You have been warned:

Lisara is a first-class Shinigami from a fairly illustrious family. Her task is to identify extraordinary humans with a lot of spiritual power, and then contract and serve them. Unfortunately, she failed to find someone suitable before she ran out of her spiritual power herself (as Shinigami, she leeches this power off her contractor). So, while she's standing alone in the pouring rain, contemplating her shame, Ryousuke approaches her and offers her his umbrella.

Ryousuke is a naive, but generally well-meaning young guy with a huge interest in anything ecchi (more the watching and dreaming than doing kind, though). His motto is "Cute Girls are Treasure", so he approaches the crestfallen Lisara to help her out. Lisara is flabbergasted and suspicious, but realizes that he's a nice guy, so she allows him to lead her home to dry up. And once they reach his home, and after Ryousuke makes the hot-blooded yell that he'd do whatever is in his power to help her, she stabs him with a magical dagger, which allows her to syphon Ryousuke's spiritual power from him.

Lisara feels guilty because this places a serious strain on him (her siphoning off his relatively little spiritual energy kills most of Ryousuke's sex drive), and she becomes more or less a (working) freeloader in his house until she finds a suitable contractor. She feels she is "too good for him", because Ryousuke's power level is too low to become her "real" contractor. At the same time, his spiritual power regenerates exceptionally fast. Things go from there.
