Hugo used his left hand to parry Sparda's attempt to strike him between the eyes with his sword before the blow even reached the target.
Hugo began to bleed as a result of the blade piercing his flesh and becoming lodged in his hands.
[Hugo: "Aghh"]
Hugo, though, would have been gravely incorrect to believe that his hand could stop Sparda's blade.
Hugo's skin was sliced through by Sparda's sword as he tightened his hold on it and increased the force behind the stuck blade.
Hugo's arm was severed by Sparda with his sword.
[Hugo: "Arghh!!! You bastard!!!"]
Hugo utilized his speed to create some distance between himself and the knight after having his arm severed.
But it was Sparda who purposely let go of Hugo because he wanted to see what else Hugo is capable of.
Turning back, Sparda gazed at Hugo, who was standing some distance away and holding his arm while displaying a painful expression.
