Raziel

The Aka Yomihime, or Red Biblioprincess, otherwise known as the custodian of the Bibliotheca Razielis Archangeli. A girl with the appearance of a small child, she has short green hair and golden eyes, although her left eye covered with an eyepatch attached to her keyhole. She has a very strong sense of balance, and tends to leap very slowly and gracefully or twirl atop of furniture without much trouble. She will answer questions with "Yes" or "No" in German rather than Japanese. It seems that she doesn't have any issues with the Professor's intentions, and seems to enjoy watching his plans unfold. She has an uncanny calm persona, and doesn't show much consideration for typical human affairs, such as death, pain, destruction, and so on. She and Dalian appear to share a very vicious and spiteful relationship.
