It seems like he stopped his regen. You are saying that it’s just because it’s more AP. When it’s clearly something else.
No. I am saying Gaban is capable of utilizing some special form of Haki or other power, which by logical necessity is channeled through his AP, which seems to impede the immortality.
By logical necessity of Swordzaru matching Rayleigh’s AP, if Rayleigh has the same ability as Gaban, this would imply that Kizaru has the ability as well. Which bodes well for all Admirals who are in the same realm of ability.
If you disagree with anything I’ve said here, you are just wrong lol.
