Re:Zero Wiki

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 aqua green 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.

After the events of Arc 5, she received a large scar on her chest from when she defended Garfiel from Theresia van Astrea.


Mimi has a bright and optimistic personality with straightforward intentions. Unlike her brothers, she talks in third-person. 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 never had any intentions of betraying or killing Natsuki Subaru throughout the series. As of the beginning of Arc 5, she has developed feelings for Garfiel, 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 Roshi. Mimi and Hetaro attempted to rescue Anastasia, but they were incidentally captured instead by Razcrew. Razcrew planned to sell them on the slave markets in the north of Kararagi. However, his plan was thwarted, and he ended up being enslaved himself. Before Ricardo could met his end by Shiroro, Mimi quickly rescued him, only for the fight to end in a draw as Shiroro does not intend to involve harming children. After the fight, she and Ricardo stopped and defeated Reisel. After with the defeat of Reisel, Anastasia vowed that if anything happened to Roshi, she would take the Pearlbatons under her care.

After the assailants killed Roshi, Anastasia, Ricardo, and the Pearlbatons get revenge on the murderers. They've lived with the Fang of Iron under Anastasia and Ricardo's care 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.

Liger (ライガー Raigā):

The Fang of Iron riding on their Ligers onto the White Whale.

Ricardo and the members of the Fang of Iron ride on large grey wolves called Ligers. Although they are similar to Earth Dragons, Ligers lack strength, but they are more agile and have higher speed and endurance. They have a high chance of winning if they were to fight in melee combat.


  • According to the author, Mimi's birthday is May 5, the same as her brothers Hetaro and Tivey.
  • Her zodiac sign is Taurus.
  • Mimi is the strongest of the 3 siblings according to the Q&A.
  • The illustrator had an idea for Mimi's liger, but it was later scrapped for being "too cute" and revised to be a normal dog.
  • According to the author, both Ricardo and Anastasia tried to teach Mimi to get her to say "I" instead of saying her own name when she's talking, but they couldn't get her to do it, so they gave up on it.
