@Vertiplano There was a panel where Ohma said that he saw naidan kill himself, meaning that it wasnt obvious enough for anyone to see and that it merited a seasoned fighter to notice the foul
@Headstack I would say that it's more like a weakened version of the blast core that removes the self damage at the cost of power, given that julius uses only his arms, whereas wakatsuki uses his entire body
@cgr julius losing to wakatsuki doesn't discredit hayami's statement though
they're both top tier fighters, just because julius was beaten through technique, it doesn't mean that he's a meathead, just that wakatsuki had better technique
