Homura

Homura was the name assigned to one of Rukia's two "children," who held her captive and erased her memories.
Homura has light green hair, with the roots appearing bright pink. She wears a light pink kimono featuring a brighter pink, down-turned collar, along with a yellow cloth around her waist.
Homura assisted in removing Rukia's memories so that she could become Rukia's sibling. When that failed, they merged to create a destructive entity known as Dark Rukia through a process of hollowfication. Their mission is to destroy anyone who gets in their way.
Flight: In the movie, she is seen floating in the air, distracting and talking to Rukia while Shizukui slashes her with his scythe.
Unnamed Ability: In the trailers, it was shown that she can make wishes, which are undoubtedly granted.
Teleportation: She can teleport to locations in a manner similar to Shunpo or Sonído.
