Very cool series
1) There are several points in the anime were they hint strongly that Arucard is really Dracula.
2) I hated the ending, which did not, I hear, follow the original manga.
3) IIRC, the BESM writeup of Arucard ended up with more points than Ifurita.
4) I think they got the effects of freak chips wrong in the BESM writeup. From what I saw in the Anime, they artificially trigger vampirism, essentially duplicating the effect of a vampire bite. This disturbed the organisation, as it implided that vampirism was an inherent possibility in everyone, rather than being something alien.
