User blog comment:Mrlmm0605/Let's Talk Bleach! - Part 3: Orihime Inoue/@comment-6812492-20150618200955

Orihime is a great character, and one of the few in the series who I feel has yet to really cut loose and show us the full extent of her powers. We have seen Orihime defend herself in a more forceful fashion, however only the one time in the Fullbringer arc, against Kūgo (http://www.mangastream.to/bleach-chapter-463-page-16.html). That surprised me, but it was a clear indicator that she had at least started to take steps toward covering her perceived weakness when it came to harming others. There was some other time after that when she was about to defend herself or attack someone, where she started calling the name of a technique that was not any of her known ones (unless it was a mistranslation?), but damn if I can remember which chapter that was now.

According to Aizen, Orihime and Sado obtained their powers because the Hōgyoku heard them cursing their powerlessness, and responded (http://www.mangastream.to/bleach-chapter-414-page-6.html). I'll grant you that it's possible he was lying, though he doesn't seem to have much of a reason to do so by that point in the story.

I can't shake the feeling that someone is going to push her too far and she's going to go totally OP on them...but I can't imagine what that situation would be right now. Since we're so far into the story I guess it would have to be something to do with Yhwach or Uryū...?
