Actually jaw training is a thing, watch creed 2 he does it for the second fight, you train your neck and jaw to take better hits and punches so you dont have a glass jaw!
This might be the anime to me back into watching anime. Last anime I watched was the Ghost in the Shell reboot back in 2018(which was surprisingly good). Gonna have peep this out. Got characters out here fighting and damn near crippling mfs with his hands in his pockets on some Yamazaki type shit....say no more lol.
Lol he say U.S.A Baby... how funny when you know Olivia was Born in Cuba and work in U.S.A only for the money and power like Yujiro XD Actually you see the only good fighter in U.S.A with the Retsu Boxing Arc and that it but Olivia is not at all an american and tbh the only one in this USA team who is actually american is Mohammad Ali jr ^^
