He can use this energy in various ways, such as firing it, manipulating it as flames, enhancing his physical abilities, or creating barriers. "???" - His other... or rather, his true ability. While "Desire" (wanting everything) serves as the energy source, its essence is the ability to steal the powers of any ability-user he kills.

Ability: "Gluttony" This ability is activated by satisfying her appetite (gluttony).

Her height is like a human child under 10, but she has large wings (devil wings) on her back, giving her a large silhouette. Her clothes are pink to match her hat. The collar has thick red lines and lace. There are three red dots arranged in a triangle. Both sleeves are short and puffed, with red ribbons tied in bows at the cuffs. She has lace with a red line wrapped around her left arm. She wears a nightcap commonly known as a "ZUN hat." Ability: "The ability to manipulate fate" Notes: Likes Shiki Matari way too much. A total tsundere. She thinks it's a one-sided crush, but it's mutual. She speaks with a refined lady's tone, but not the overly formal "desu-wa" type; rather, she uses feminine sentence endings like "-wa ne," "-koto," "-kashira," and "-janai." She gives rather suggestive orders.
