Zwei is a sadistic character from the anime Pandora Hearts. He has white hair and is a member of the Baskerville family. Zwei is a very mysterious character and his backstory is not fully known. However, it is known that he was once a human named Vincent Nightray. Vincent was a very kind and gentle person, but he was also very lonely. One day, he met a woman named Rachel and they fell in love. However, Rachel was actually a witch and she used her powers to trick Vincent into becoming her servant. Vincent was forced to do terrible things under Rachel's control, and eventually he became so twisted and corrupted that he became the sadistic character known as Zwei. Zwei is still haunted by the things he did under Rachel's control, and he is constantly trying to find a way to redeem himself.
