Crusch Lulu is an albino white lizardman and the chieftain of the Red Eye tribe. Over the course of time, she proved herself to be a strong practitioner of magic. Currently, she is the strongest of all the magic casters that exist within the lizardmen tribes. Her magic consists of controlling nature and summoning spirits to assist her in different ways. She has snow white scales and spotless purity, bright red eyes like rubies and slim limbs. Since she was born an albino, in the lizardmen community that would normally mean that she would be abandoned. In Lulu's case however, her parents decided to raise her even with this genetic fault. Due to her this, Crusch burns easily in the sun and is very weak against direct sunlight, which forces her to wear a ridiculous bush outfit during the day. Zenberu teases her about it and refers to her as 'Plant Monster'.

He met Zaryusu when he visited Red Eye tribe in order to propose the formation of an alliance. She revealed that when the famine in the Wetlands occurred, the Red Eye tribe managed to stave off extinction through fratricide. However, unable to bear with the guilt and shame, Crusch led a rebellion against the previous chief. Her rebellion was a success and the mantle of leadership was passed down to her. Eventually she fell in love with Zaryusu, a feeling had been mutual since the moment he had met her. Before the lizardmen's duel with Cocytus, Crusch asked his lover to impregnate her, fearful that he might die. Indeed, after he was slain in battle, Ainz made a deal with Crusch Lulu where he would revive Zaryusu in exchange of her keeping a close watch on whether there are lizardmen thinking of rebelling. Even after the assimilation of her tribe, Crusch is still fearful of Ainz, as when he inquired about her and Zaryusu's newly born child, and thinks that Ainz will take their child away.
