Zander, the X angel under the wisdom angel, one of the seven archangels, is the apprentice of the ultimate knight Phyllis, and he was Amisius' brother when he was young. Zitangzhen, the eldest son of Zitangjia and the eldest brother of Zitanghuan, lost his memory for some reason and became the Z angel of the Seven Gods-life's core monuments.
