Schuldig (シュルディッヒ)

Both sadistic and masochistic to an extent, Schuldig enjoys messing with people's heads, which is all too easy given his power of telepathy. He claims that people's minds taste like honey; however, he also complains that at times he can't tell which thoughts are his. Schuldig means "guilty" in German and Dutch.
