Shizuku

Shizuku was the name given to one of two of Rukia's "siblings" who took her captive and erased her memories.

Appearance
Shizuku has light green hair, while the roots appear to be bright pink. Along with that, she wears a light pink kimono with a brighter pink, down-turned, collar. She also wears a yellow cloth around her waist.

Personality
Shizuku helped to rid Rukia of her memories so that she could pass to be Rukia's sibling. After that failed, though, they merged together to create a destructive being, called Dark Rukia, in a process of hollowfication. Their mission is to destroy anyone that get in their way.

Synopsis
In the trailers, Shizuku seemed to distract Rukia while Homari slashed her with his scythe. This erased her "heart" and memories. Afterwards, the siblings convinced Rukia that they were her brother and sister, but they hadnt been given a name. Rukia still remembers her Shinigami friends, Renji Abarai, in particular. This leads Shizuku to get angry and wish for all three of them to be one. This is granted, resulting in Dark Rukia.

Just when Dark Rukia had thought everyone had forgotten about her, Ichigo appears and talks with her about their "bonds." Dark Rukia proceeds to attack, but Ichigo is holding back in fear of hurting his friend. Byakuya Kuchiki and Renji appear and tell Ichigo that she is undergoing hollowfication and must be destroyed. Ichigo refuses and instead lends his power to her (in a similar manner as the day he and Rukia met), leading her to revert back into a Shinigami. The siblings disappear, but not before being given names by Rukia.

Powers & Abilities
Flight: In the trailers, she is seen floating in the air, talking to Rukia while Homari slashes her with his scythe.
