オルガ＝ニザ＝カイト

The supreme commander of the Angelic Forces and the one responsible for cloning the ranked Angels after their death or subversion at Klaus's hand. Her manner of speech resembles that of a robot, and her train of thought takes logic to its extreme. She recognises Klaus as one of the "test subjects" and attempts to reclaim him when he and his forces invade the Altar.

She recognises all of the ranked Angels by name and will engage them briefly in conversation if they are present in the final battle and are engaged in combat.

When defeated, Klaus surmises that the order to clone the Angels wasn't strictly given at the behest of the God the Angels serve, instead Olga had some ulterior motive for taking action which is not fully explained.
