Sadira. a close friend and sometimes battle partner of Lamia. like Lamia, she too is a demon, but she is very intelligent (hence her glasses) and can also summon dark beings, though instead of having the powers of Diablo the Prime Evil and Imperious the Archangel of Valor, her power is from a being composed of pure darkness of no name and who sometimes acts as her guardian. and when she uses her full power, she can use her stained glass tail and show her foes "the true face of the world"
