Puri can one-shot, sure.
The problem is he has to hit him. Which isn't happening, lol. Even if speed was equalized, or hell, even if Puri had the speed advantage, he still would never hit Yujiro.
The gap in skill is just... absurd. Yujiro is one of the most skilled characters in fiction, comparable to the likes of current Garou.
We're talking about guy who can look at you a single time and see the outcome of the fight. A man who fights and stomps analytical predictors on a daily basis and can copy their entire martial arts prowess in a glance. He's even predicted and dodged attacks he had no awareness of, lol.
Then you give him the 2x speed advantage? Haha. Yeah no, this one isn't going well for Puri.
Yujiro would glance at him and immediately know everything he'd do in the fight, alongside all of his pressure points, weak spots, current health, etc. A bunch of stuff he'd then exploit to obliterate the guy in close quarters.
