Mammo

マーモ

Mammo (Māmo) is a member of the Selfish Trio and the sole woman in the group. She makes her first appearance in episode 1.
Upon her debut in the first episode, she apparently assists her partner by summoning a Jikochuu (monsters created by capturing the hearts of people who have thought of doing something selfish), such as Ira. She also possesses bat wing-like objects behind her ears, similar to the rest of the Selfish Trio.
