Mimi Pearlbaton (ミミ・パールバトン) is one of Anastasia Hoshin's followers and is one of the three vice captains of the mercenary group Fang of Iron.
Mimi has blue eyes and long orange hair which she ties into two tails. She has orange cat ears along with a tail and wears a white robe.
Mimi has a bright and optimistic personality with straightforward intentions. She typically acts like a child, often causing problems for her brothers Hetaro and Tivey. She considers the other members of the Fang of Iron to be family and loves them, referring to Ricardo as their father, though as it's her own unique way of loving others it tends to cause problems especially for her brothers.
Mimi is one of the few people who have no intention of betraying or killing Natsuki Subaru. As of the beginning of Arc 5, she has developed feelings for Garfiel Tinsel, leading her to drag him around Priestella and claim to "feel weird" while blushing when he patted her head.
Sometime in the past, Mimi, Hetaro, and Tivey were abandoned by their parents and were taken in by Ricardo, who they've lived with ever since.
Divine Protection (加護 Kago): Mimi has the Divine Protection of Trisection (三分の加護 Sanbun no Kago), which she uses in conjunction with her brothers Hetaro and Tivey. It enables them to bear each other's physical and emotional burdens and can also be used to split damage between them such as to block death blows. However, as Mimi is the strongest out of the three, her brothers are often stuck with bearing her burdens. In addition, they can launch a destructive interference wave using the Divine Protection and the other siblings, though Mimi is limited to five times and Hetaro and Tivey are limited to two times, so the maximum usage per day is four times.
Resonance Wave: The triplets unleashes burst of a violent destructive mana from their mouths together. Only two of the three of them can do it at a time. This ability was learned from Ricardo as he is the originator of that ability.
Earth Magic: Mimi has shown to be a adept at earth magic and shown to conjure an unnamed magic shield and other spells.
