Story Summary
The main character of Angel Sanctuary is a teenager named Setsuna. He's in love with his younger sister Sara and is chased by demons and angels who are telling him that he is the reincarnation of a powerful angel, Alexiel. He finds he can't escape the angels and demons, and the people he loves get dragged into his mess. Angel Sanctuary is a short OAV with no conclusion.

My Opinion
Angel Sanctuary is based on a 20 volume manga series by Kaori Yuki. The OAV follows the manga pretty well, besides cutting out a few plot elements and characters. There is also no conclusion to the OAV. It's a shame the OAV is so short, but the animation looks cheap anyways. Angel Sanctuary is an amazing and enormous story, with dozens of characters. If you dig the anime, then I highly recommend the manga series which is available in english from VIZ.
