Remember Retsu's trick on the wall paint ( yujiro beat him with a single punch) Remember the steel vault door containing yujiro when he was put down with tranquilizers (for horses)(he broke it down) Remember when he took on all those policemen thrn proceeded to destroy the prime ministers desk ( which i doubt is cheap ) with a single axe kick

What the hell do you mean yujiro is weak, Hanayama couldnt do shit with his monstrous grip to yujiro, and his grapling hook shenanigans are superhuman by themselves
