During the War of the Ancients, in the Land of Lumeria, Eblis, a supreme race invaded the land, bringing terror and darkness. Humans and Tera united to destroy this frightening clan. However, their strength and alliance were not enough to annihilate these creatures. 13 lights came down from the sky and 13 warriors emerged, they were the 13 STORMS, who eliminated the Eblis and sealed them in the 13 towers. After many years, the rumor about the 13th Storm, known as Squall, destroyed his own tower. As a result, an invasion occurred in the village of Orchidia led by the Eblis forces, where Lucille Starlite and Mark Knighthood live. Due to this attack, the remaining warriors of Orchidia were given a task to find a scholar who could analyze the “SOULQUARTZ” that reacted during the attack.

Xeruz is a perverted, drunkard knight who traveled in the land of Lumeria seeking for the name "True Noble". He met Lucille and Mark in Lecucao, they journeyed together in order to search for a Scholar and search for the answers behind the destruction of the 13th tower where the Eblis were sealed.
