It was designed to contain the demon of sloth Eve Moonlit after Irina recognized it as residing inside Mikulia Greeonio. Once the demon moved into the doll, it would use its hypnosis several times to impersonate the identity of several woman, including Mikulia Calgaround, Platonic, and Margarita Blankenheim.
During the Duel of Merrigod Plateau, Eve's soul fused with Irina Clockworker's and Levia barisol's to create Ma, leaving the doll empty. After Michelle Marlon's death, Ma took advantage of the situation to expel Irina's soul into the doll and convince Gallerian Marlon that the soul belongs to Michelle, leading her to believe she is as well.
