I read the first chapter but it was kinda meh to me.I ll wait for some more chapters to kick in and give it another try.
The main protagonist is a copy of Alphonse tho :|
Kishimoto screwed up Kakashi,he made him an MS ***** with that Kamui.We know his chakra reserves are low,therefore he cant spam jutsus but at least he could have introduced one different jutsu he had copied in every fight he took part.
