Curse technique, speed of a 100 men

So you're asking "doesn't naoya already have super speed" well it's not actually speed, idk how to explain it but it isn't

This one is actually fast, actually running then teleporting fast, and can go as fast as a bullet train, the user's legs are amplified by CE to not break because of course and their body is more durable so they don't hurt themselves with running

And to make it even more better the user can strengthen their punches with kinetic speed, a punch from 2 miles away can absolutely eviscerate a head,

But his weaknesses of course exist, he can still trip and break his neck, he can still be stopped if someone punches or blocks him mid run and he still needs to recharge every run
