so here is whats going on
1) those kages wont be used as fighters, but will be used to inform sasuke bout what he wants to know as that was the purpose of sasuke in first place
2) if ever those kages were able to break from edo tensei as 2nd hokage is the creator
here is what is gonna happen ( my opinion )
- madara facing hashirama will be priceless
- minato facing tobi and knowing he is obito and he was the reason of their death will be more priceless
- minato facing naruto, kakashi well...its gonna be surprising
- hiruzen, tobirama, well i dont know what might go with them but what im sure of, hiruzen was the one who knew all about the uchiha masacare and ofc sasuke wont be calm untill he knows and hears it from hiruzen, as for tobirama, he will tell us how to defeat the edo tensei and how to stop madara, and hashirama will take a big part of that
as for sasuke, we knew he said that he must hear it from them first and decide what shall he do and make up his own mind meaning his revenge isnt his final decision, so him helping at war after hearing the truth from the hokages, and we even might hear more things that we werent told about, only hokages knew about not even anbu ( itachi - madara )
as for orochimaru..LOL he is the boooosssss, i always kmew he was gonn be the main villain...but i really wanna know what will orochimaru do after letting sasuke hear them speak the truth..will he set them free, will he return them to death, will he attempt to take sasuke body??
as for yin chakra in minato, he is considered as a jinjurukii, i bet naruto and kurama will sense that chakra and will realize smth happened
will naruto get kuramaa's full chakra?? a new power??
i definetely gave this chapter 5/5
did i miss anything here??
