Then- goodbye, Orihime.
Who: Sora (Orihime's brother (Hollow Form))
Notes: The character is the Hollow form of Orihime's dead brother. When he comes back as a Hollow, searching for his sister, he attacks both Tatsuki and Ichigo, in an effort to get her to come back with him (seeing as those two tore him and Orihime apart). In this process, he even threatens to kill Orihime, but eventually regains his humanity after Orihime lets herself be attacked by him, and after such, he stabs himself with Ichigo's Zanpakut?, allowing him to pass onto the Soul Society.
