Lmao NB is on a roll with the stupidity.>calling a official Kishimoto illustration fanfic
:lol
Stop with the denial and just let it go.
First of all no one ever said it was fanfic kiddo. Don't get your panties in a twist. It's a promotional image included with volume 1. That's fact. Is it canon? No. Is everything drawn by Kishimoto canon? No. It featuring canon characters doesn't mean that it's in the storyline, that's the point of a promotional image.
Imagine being desperate enough for a fictional character you fan to get new powers that'd you lie to yourself and tell you that a promotional image included with Vol 1. of Boruto is canon. Grow up.
