Ciel is one of the main heroine from a hentai game called Tsuki Hime. She had an immortal body and throw blade as her weapon. She can create blade using pages of a bible and she is working for the Church.
Behind her is Alexander (I think.. forgot his name) from Hellsing. He is a regenerator who throw blade as his weapon. He is a true freak about killing vampire.
Actually reverse is more possible. Tsukihime came out in 2000. But i doubt both of it. Not to mention while Anderson throws bayonets, Ciel throws swords actually.
actually anderson's first appearance is before hellsing. "angel dust anderson" as walter states in the series, from angel dust hentai/manga by kouta hirano.
