Personality

Lye believed that everything came down to experiences and the one who manages to get better knowledge is the one who enriches his life and wins over people. Remarking that knowledge is power and memories are bonds, he ultimately concluded that it meant that he and his philosophy were the greatest. Because of that, Lye focused on the quality of the lives he ate, often giving his opponents a chance to "prove" themselves as worthy meals before ultimately eating them and claiming their abilities for himself with his Authority of Gluttony, which befitted his title of Gourmet.

Unlike Roy, Lye strongly believed that if the number of lives in the world is limited, then the amount of worthy food is limited, and so he would not miss a single chance to eat someone. Due to their differences in how they approached eating, Lye held distaste for Roy's way of fighting, thinking that just trying to eat anything would lead to the loss a "gourmet" platter. Lye also showed to look out for Rui, pointing out how she may be happy if he was to eat Otto, Felt and Dynas, though he would ultimately abandon her for himself if put in danger. Although his past with his siblings is unclear, Lye seemed to show a strong dislike towards merchants.[1]
