Mammo

Mammo (マーモ Māmo?) is one of the members of the Selfish Trio and the only woman in the group. She first appears in episode 1.

As she first appears in the first episode she apparently helps her partner by summoning a Jikochuu (monsters that are created by capturing the hearts of people that have thought of doing something selfish) like Ira. She also has bat wing-like objects behind her ears like the rest of the Selfish Trio.
