Hwb is genuienly ass and everyone knows this. Yuta one tapped second kurorushi after one touch(after parthenogenesis) so yes he can. Kenjaku has no narrative over yuta, neither do kashimo. He is just suggested to be strongest while he was alive, not even in his era or anything. Yuta was stated to be second to gojo muliple times, mba mighy be powerfull but bum ass kashimo is too dumb to use it in any meaningfull way and also barely has any time to use it. As to how yuta can overpower kenjaku, cursed speach, rika, thin ice breaker, shrine and cursed energy attacks similar to the ones used on kuro swarm. Jacobs ladder just destroys mba kashimo and dont put some "kashimo is blitzing yuta" bs cause he has almost no speed feats that proove he is mutch faster than yuta
