The first few chapters will have very little to do with the MC and focus quite a bit on the situation in Konoha, don't expect the MC to gain Chunin level ability soon just because he had Elite Chunin level Chakra off the bat.
He is quite useless in the beginning, thanks to his lack of knowledge and untrained body.
There will be a few chapters predating the Origin chapter, I'll number these in negative and include them into the auxiliary section.
