Keiran with a slightly different outfit, slightly longer hair, and a spear.
Some might say that this isn't that impressive, that at this point I should have something more impressive to show, but I made the conscious decision to not go overboard. It's the final chapter, and I don't want to introduce some super insane wacky forms or powers that won't ever re-appear again. It's still Keiran. The same character you all followed for all this time.
Also, yes, this is a full-page panel. It was a conscious decision.
