Pretty much. I believe Ishida commented on that when they first went to Hueco Mundo.Now isn't HM supposed to be just as if not more densely packed with spirit energy?
It's just that the restoration trick is time consuming and insanely dangerous. It involves working yourself nearly to death from physical and mental exhaustion and then getting shot with a spirit arrow exactly 19 mm to the right of the heart. (If you are American, that's 0.74803". Exactly.)And why is everyone acting like Complete Holy Form makes you lose your Quincy powers forever and ever? We've got straight up proof via Ishida that the powers can be restored. With all this theorizing about Ryuuken being somehow related to Emperor Manlybeard it's not a big leap to theorize that if one knows the restoration trick the other would.
Also, you will still be powerless until you can find another Quincy to help you, so if you don't manage to kill all your enemies before you burn out, you are in trouble.
Also also, I'm not sure but I think it only works once.
So, unless Emperor Manlybeard really has figured out how to let Quincy keep their powers after using Letz Stil, it still kinda sucks compared to Resurrección and shikai/bankai.
Likewise, he may be against fighting Quincy on principle, but that doesn't mean he will join their cause. Heck, he thought the shinigami were in the right to whipe out the Quincy the first time around. Lord knows he has no personal reason to want to see Soul Society destroyed. Oh, he probably still wouldn't pass up a chance to headshot Mayuri if he thought he could get away with it, but he's pretty cool with the rest of them. He wouldn't want, say, Rukia and Renji to die.
It's a pretty tricky situation - the most likely thing would be for him to just sit this one out, but that's pretty much guaranteed to not happen. I really wonder what Kubo is planning here.
Honestly? My guess would be: "With a healthy degree of suspicion." He's a smart, observant guy who doesn't jump to conclusion or gets fired up about stuff, and he's very skilled at deduction.But how would he react if say his dad turned up dead mysteriously and the quincies show up to put the blame on soul society.
I mean, the guy who pretended not to be a Quincy, tried to talk Ishida out of being a Quincy, and who by all accounts don't want anything to do with the Shinigami and has been ignored by them for years, suddenly gets killed by Soul Society, and at virtually the same moment a large and highly organized group of Quincy/blatant Nazi allegory show up out of nowhere and want Ishida's help with this war they are coincidentally waging on the Shinigami?
Ishida is going to take one look at that scenario and call bullshit. Even if he pretends to believe them, it will last exactly as long as it takes for someone to slip up and say something incriminating.
