Second, Murasame isn’t Zaraki’s. if you’ve noticed, everyone whose Zanpakuto that has turned against them has at least had Shikai. Zaraki does not have Shikai, and since the abilities reflect the owner, Zaraki’s woudn’t have Kidou abilities.

Third, ichigo will be fine. he can hollowfy and use his hollow powers to defeat the other Zanpakuto’s without needing the use of Zangetsu (though it would be helpful)

it also can’t be Yorouichi’s because even if she didn’t carry her’s, what reason would it have for killing the shinigami? i think that this is just another remnant species (like the bounts) that for some reason wants to kill the shinigami because of something bad soul society did (again)

i also think that the Zanpakuto’s don’t have a choice (except for the one with the scythes, i forgot the owner’s name)

in the end Zaraki wil probably defeat Murasame with his shikai that he will have obtained just before the fight, or ichigo will create a stronger bond with Zangetsu and easily win in the end

Also, can Admin please stop using megavideo? i want to watch more but it makes me wait an hour
