What exactly are you trying to say lol
do U understand that kishimoto is telling a story?...and that he doesn't care how jutsu A counters jutsu B, when he intends to
specifically_ display the -situational- quality of jutsu B in a -scripted- scenario, thru literary mechanisms?
Itachi is greater than Muu. the fact that Muu cant be detected by doujutsu doesn't change this fact.
Portrayal is portrayal, match ups r matchups & feats are feats...but alas, kishimoto only cares about portrayal in his narration~
Naruto isn't written so that U can make match up threads, its just a narrative. It doesn't require consistency.
So don't complain because u cant separate canonically based logic from bias in a hypothetical match of separate fictional elements(no pun intended).
Nevermind the fact that Hiruzen is supposed to be, the historically, greatest ''offensive skill-smith & tactician'' shinobi in the story, designed specifically to outclass characters exactly like Mei/Danzo/Kisame/Kitsuchi/etc.
a fire user in kakashis unit? most of those ''extras'' weren't even given names...
theres a reason Sasuke wasn't spamming fire & escaping thru the roof when he fought Mei...figure it out yet?
