after todays chapter it's clear kishi could care less about progress and structure that he built since this manga started.now i guess everyones so busy getting a orgasm over revived kages that no one thinks..wtf just happened??how many of you was there not that argued how can sealed kages be revived if they're sealed??it's simple logic based on what we've seen only to have kishi bitch slap you and saying ''dude you just need the shinigami mask and it's all cool to reverse the irriversable''.now you have sarutobi&minato(seen as one of the most intellengent) looking like d@icks coz they ultimate jutsu that cost them there life was just rendered useless when someone puts on a mask.also it seems the shinigami is prety easy to fool since you can out smart him by faking your own death with substitued wth???also....zetsus can now be used as sacrifices????seriously??but i guess you guys care more about seeing your fav charater in action then about things making sense
Look at what your saying, dude.. It makes sense.
All of the Kages were sealed within the Shinigami, who could be used to preform jutsu's, which we learned in the 3rd arc.
It's only logical they can be unsealed via the same Shinigami.
Zetsu have human bodies and human DNA, offcourse they can be used as sacrifices.
And the jutsu isn't reversed, btw. They're still dead.
