I was just reading through the manga when all of a sudden Orihime's brother came to my mind. If you guys remember he, to suicidally kill himself, stabbed himself in the face with Ichigo's sword. The thing was though that his mask was broken off and it was by his own will.
Do you guys think it's possible he became a arracran? Because while in Soul Society they never met Orihime's bro.
