It wasn't Orihime's actions towards Ulquiorra that struck me as insanely ooc, but her utter non-action through this arc and the latest chapters. NOT healing Ishida, asking Ichigo's CORPSE to save her. It's a far, far cry from the girl who stood up against Hollows and wouldn't let people hurt her friends. The character rape is in how Orihime has been downgraded from someone who would go into Soul Society to save her friends and was pleading with Ishida to let her fight and got trained by Rukia and then just stood idly by.
