There's no arsepull, everybody learns everything off screen in this series
This! Even if you are saying this sarcastically, I am still glad to see someone at least acknowledge the existence of off screen training.
Here's the problem with this fanbase. Everything is an asspull because nobody accepts the notion of off screen training! Boruto and friends can't do a thing without it being an asspull if we didn't see them go through rigorous training for it. Also, everything is supposed to be so hard that only advanced jonin or kage level shinobi should be able to do it after years and years of training.
Boruto made a sandwich, you say? That's an asspull! We never saw any chapters where he went through 20 years of culinary training! That's a high jonin feat!
Sarada blinked huh? What?!!!!! That asspull! That's a kage level feat! She wasn't supposed to learn that for 30 years!
When are people going to learn that this isn't Dragon Ball where the heroes get years to train for impending threats?
