- A family of five rat witch sisters—there are initially six, but the eldest sister is killed by Medusa. They are close friends with Eruka, who is forced to trick them into thinking the DWMA was responsible for their eldest sister's death, thus joining Medusa. They can transform into mice and possess magical whiskers that can be used as weapons. Their normal forms are small and child-like, and they communicate through mouse-like squeaks. They can combine into larger, more humanoid forms which increase in maturity for each sister involved in the transformation.
