Yujiro's punch can honestly be considered an outlier. I'm not huge on baki either, but it also depends on the power of it, if it's low magnitude, it could be vastly below city level. Though, the fact he did it casually if the impressive part, but again, possible outlier, many debaters don't accept it.
Darkshine one shots durable demon level threats with a light jab, he's like, multi city block level while massively casual. Garou was using the combined martial art of Bang/Bomb that they used to crack Elder centipede's shell, whom could no sell Genos' huge energy blasts, and yet Garou can only do minimal damage to Darkshine.
I don't know everything about Baki, i made this thread to see if anyone can make a case for Yujiro, because from my basic knowledge, he gets splattered.
Darkshine scales above hypersonic. I'm handicapping him in the second round, making it more fair for Yuji.
