You stole Sister's horn... and on top of that, you're not satisfied with robbing me of my reason to live... ARE YOU GOING TO ROB ME OF MY REASON TO DIE AS WELL!?
~ Rem

Rem is one of the main characters in the Re:Zero series of light novels, anime and manga. She is the twin sister of Ram.


A long time ago, there existed a small village in the kingdom of Lugunica inhabited solely by Oni, human-like demons with the ability to grow horns to reach superhuman levels of power. That village was home to many prodigious warriors, but none were as peculiar as a particular set of twins. Ram and Rem were born with a single horn each, unlike all other Oni, which have two horns. The older twin, Ram, was an extremely talented and powerful magic user. Rem, however, was more on the clumsy side, always depending on her sister.

One day, Rem realized that she needed to be more helpful in order to become as talented as Ram, but that didn't go very well, as she got lost in a forest when trying to find ingredients for a dish, only to be rescued by Ram. Despite her frustration and inferiority complex, Rem still loved her sister more than anything else, and she looked forward to learning more about the world with her help. But then, tragedy struck. A grim organisation known as the Witch's Cult invaded Rem and Ram's village and brutally murdered all of its inhabitants, except for Rem and Ram, who were able to fight them off with their powerful magic. However, during the fight, one of the cultists sliced Ram's horn off, rendering her much weaker. Rem secretly felt joy at that moment, knowing that from that point onward, she was going to be the superior sister.

Soon after the destruction of their home, the twins were taken in by an influential man known as Roswaal L. Mathers, one of the most powerful mages in Lugunica, and owner of large portions of land. The twins were allowed to stay in Roswaal's manor in exchange for them working as maids with the assistance of the chief maid, Frederica Baumann. During their time working at the Roswaal Manor, the twins were assigned to take care of Emilia, a candidate for the Lugunican crown. This alliance also lead to them meeting a strange human known as Subaru Natsuki.

Powers & Abilities

  • Synesthesia: An ability that she shares with her sister. It allows them to share their feelings with each other through telepathy.
  • Magic Expertise: Just like her sister, Rem is able to channel Mana through her body in order to cast magic spells. She specializes in Water magic.
    • Huma: A defensive water spell that creates a water shield that can easily stop magic projectiles. It can also be used to freeze blood.
    • El Huma: An offensive water spell that can be used as a contact move that instantly freezes the enemy or to summon ice pillars from the ground.
    • Al Huma: Rem's most powerful spell. It allows her to fire ice spears as projectiles. The size of the spears can vary greatly.
    • Healing Magic: A type of water magic that heals wounds.


  • Morning Star: A large steel flail that Rem wields with ease. Due to the chain's length, it can strike enemies from afar without losing power.
