Dark Rukia

Because she is a fusion of three beings, Dark Rukia carries traces of Rukia, Homura, and Shizuku at once. Her hair and her now feline eyes have both shifted to lavender, and she goes barefoot in a ragged, casual white kimono, a red high-collared cape hanging from her shoulders and a length of gold cloth wound about her waist.

Nothing of the real Rukia survives in her temperament. Governed by the merged will of Homura and Shizuku, whose hatred of Soul Reapers and refusal to share Rukia define her, she wants every Shinigami dead. The tighter the siblings' grip grows, the crueler and more unhinged she becomes over the course of the film.

She is born when Homura, unwilling to lose Rukia to her returning memories of Ichigo and Renji, wishes the three of them permanently joined. The result seizes one of Mayuri Kurotsuchi's inventions and looses ruin across Soul Society. Ichigo refuses to strike the girl inside her, dodging her assaults and pleading for her to remember, while she vows to erase his memories of Rukia with her weapon, an enormous crimson scythe that can phase harmlessly through a body yet wipe out chosen memories, the same power that once made everyone forget Rukia had ever existed. After Byakuya briefly binds her and recognizes his late wife Hisana in her features, Ichigo at last drives Tensa Zangetsu through her, freeing Rukia and destroying the Hollow that had joined the siblings.
