At first I didn't want to believe it but after these spoilers I'm convinced.
We see momoshiki gives boruto a seal after he died.
Now that same seal is connected to these new group of people.
It always took a group of people to beat otsutsuki powers.
If kawaki got otsutsuki powers it's understandable that he would spank naruto.
If ninjutsu is useless then Naruto would have to rely on taijutsu.
And that wouldn't do no good cuz they'd use ninjutsu on him instead.
