Review Detail of RedGunner in He used to be a Reserve Genin

Well written fanfic and the author has put a lot of effort into research and getting his facts right while introducing some new things. Border skirmishes arc is the only reason I am not giving it five stars. That arc was bland and boring, the reason we read fanfic is to see new characters mix with the already existed characters in the original but this particular arc has all the things that I did not like and felt boring. I hope the author doesn't get lost in introducing new scenarios and characters while turning it into a new book instead of fanfic. I like exploiting a new plot but it should have a good mix of the original storyline.
