A simple chart of the shinigami zanpakutou in humanoid form. I'm not sure if there are any tags for them as characters yet or what would be the best way to make a tag for them that included the owner's name.
maybe i missed something but where the heck is zaraki while all this is happening, i figure he'd be having the time of his life with new strong opponents to fight all over the place
Probably Kenpachi's being left out of this arc because his zanpakuto's name is unknown, and having it "freed" would inevitably reveal its name. Which would get contradicted when/if Kubo decides to reveal its name in canon. And same for the sword's powers, whatever they might be.
