Kishi made 8 gates for a reason. Guy can open all of them, and I think that he will release the 8th gate near the ending to help. This would obviously mean death for Guy but its my opinion.
Wouldn't that be "sweet" if he does it and dies and that allows kakashi's sharingan to somehow further? But I love guy so I'd rather him live but if he has to die he better take someone out
Yeah I don't want him to die but I really want to see the 8 gates! And honestly if I had to choose between, Rock Lee using it and dieing, or Gai using it and dieing... I'd choose Gai any day. Lol xd
If things keep going the way they're going he's not going to be left with much of a choice, at this point even if reinforcements do arrive they won't be able to do anything against the Juubi. I see Guy sacrificing himself here pretty soon.
