Hibari knew the risks and yet he continued to move forward, blocking all the knives and hands and cutting all the wires that were attempting to suffocate him and kill him. He was hit twice during this, but wounds were merely signs of struggle in an epic battle. It was not weakness, although he did think that he slacking off too much to let all of this happen at once.
He continued to swing his tonfa hard all over Bel's body (the face, the chest, the stomach). At this point, he went around and hit back behind his back, not minding and not caring that he was maybe—just maybe—breaking bones in the process.
