Rasiel

Serving as the guardian of the Bibliotheca Razielis Archangeli, this enigmatic figure is often called the Red Biblioprincess. Despite her small, child-like appearance and green hair, she possesses a supernatural grace and an eerie, detached composure regarding human suffering. She communicates using German for simple affirmations and maintains a curious interest in the Professor's unfolding schemes. While she remains calm, she shares a notably bitter and spiteful rivalry with Dalian.
