Did I miss something? Since when does lightning become invisible or better yet not produce noise. The mechanics of the lightning chakra nature are based on vibration. I hope you're not using the anime filler to say it's lighting natured.
It’s a lighthearted joke, don’t dig too deep.
Lightning or wind it’s still a good jutsu against kamui phasing
I agree the lightning nature is stupid but that’s what they said
I just made the reference because Kakashi is the only other to try and merge lightning with it.
But far as I’m concerned both are filler based on what Kishimoto started for them with Ootsusuki introduction, chapter 700, Naruto Gaiden, Mitsuki 1shot, The Last & Boruto Movie. In other words, both are their own interpretation and continuation of Boruto.
