Well this started looking very loli so I wasn't really expecting to have much interest in it
But suddenly ... in the middle of Ep 1 ... it changed and it stayed changed (and the main protag loli ages herself 9 years)
I'll call this a bishoujo coz they seem to have the need to have panty shots often - even to the point of deciding to sensor some of them
Anyway the story is about Taito who has a recurring dream of making some form of a pact with a vampire when he was young (about 9 years before) ... until a sudden event occurs half way through the show and he finds that his dream might actually have been true ...
Much more of the story would spoil the first episode coz there a few unexpected bits about it.
I'd expect any objectional content list to include 'blood and gore' :)
Seems so far that it could be interesting - just a pity about the rather regular and unnecessary panty shots (and the fact that the other 'girl' looks so young)
There's a manga that been going for almost 2 years (but only 1 volume) and 2 separate light novels (7 & 3 volumes each)
