No, they sent him to take over Naruto. But not completely, a part of him still remains. They sent Aizen to take over Naruto because even if Aizen did teach him, Naruto would not be strong enough with that body; so they sent Aizen inside Naruto so he could transform into Aizen's body at anytime. They also had other reasons that I cannot say since they are gonna be revealed later into the story.

Do you mean how he reincarnated even though he is immortal?

I don't quite understand what you're meaning to say, could you tell me in detail?

that's crazy tbh

Gotta put him inside Naruto's body or it'll be a whole different story.

ofc*

of, Aizen gonna be OOC in this

I was planning to use it on someone else, Hinata isn't even in the pairings.

Minato had to take the day off for Kushina having a little 'thing', I'll reveal it later in the story.

why?

my own rating for the story, this is my honest opinion!

I'll try my hardest!

Idk man, some sort of hillain? lol

Average I think, it is good. But please update the story, it has potential. Should I adopt it? I can if you want since it seems like you won't update the story, it can be a good story.
