Well her annoying voice can shatter glasses for sure, if you consider it a power
Yup, her powers affect both. To be precise, she has the power of UNDO. She just negates the injuries, it's not about speeding up natural healing (which is how normal healing powers, like those of 4th division, work).
She always reversed time/space for a specific area, so I'm not sure how much spirit particles are coming into play here.
Her power from what I understand is "event rejection". It has never actually been said that she can only reject reishi based things or that reishi contributes to her powers all that much.
she has the power of ctrl+z
Honestly, all you need to know is she is very broken. Her nature is the only thing holding her powers back.
"She has the power of ctrl+z" - ulquihorror
And it does seem her powers have very small limitations. The only instance we have seen them not work was against Ichigo and one could probably argue that the reason it did not work was because there technically was nothing to heal.
i know her brother gave them to her so they have a sentimental value, so is it her affection towards her brother that increases her reishi? or do they actually have traces of his reishi left on them? or do they just serve as a proxy by witch to materialze her powers, similar to ichigo's substitute shinigami badge with the full bringer powers?
Well, the pins appear to be more closely related to zampakuto than to fullbring. They have proven to be alive and have 6 personalities of their own so far which is distinct from fullbring which merely has the souls of objects collect memories and take form. It appears as a sort of middle ground between them.... I doubt her brother had any special powers or anything so it can't be that he made them into something that could take or make a god spitting ability. If they are kinda like zampakuto then logically the power should originate from orihime herself and the pins would similarly be just a middle man between her abilities and the real world. What makes the pins special? Are they even special? If they are special, where did orihime's brother get it? If they aren't special then why was orihime's soul imprinted in them like that?
Speaking of the pins having personalities, wasnt it mentioned early in the series that orihime will be able to use said personalities individually? Or was that only in the anime? Im curious what each persons power will be...
I'm curious to see if Orihime is ever going to use her abilities to be useful in the midst of battle. She is completely haxxed out and has almost never been useful.
