a baobhan sith shrine
You remember "Laura", don't you? She was the sexy, seductive baobhan sith from Order 09, the female vampire who hypnotized her way into the Hellsing mansion and went on to do the impossible before being shot and promptly forgotten.
The baobhan sith, in my opinion, never gets enough credit. This is my tribute to her, the character who kicks off the turning point in the Hellsing anime, whose brief visit is rooted in vampire tradition, and reverberates throughout the final, climactic episodes. Oh, and she takes Integra's shirt off. Rowr.
