He is not seen until the World of Ruin, where it is assumed that he purchased a priceless work of art picturing a woman. However, he also purchased Lakshmi, an esper. As a result, a demon, Chadarnook, possessed the painting. Owzer hires Relm Arrowny to take care of the situation, but she could not do it without the help of the player party. After Chadarnook is defeated, Owzer gives the Lakshmi magicite to the party.
