I was seeing red.
I could see the edges of my vision darken as I glared at the bastard with all the hate I had.
Sound was being drowned out around me and the beating of my heart was getting louder and louder as every thought in my head was directed at tearing this bastard to pieces limb from limb.
Before my mind could succumb to the animalistic rage however, I saw Katsuki whip out her hand to stab her own knife into her father's stomach, causing him to bowl over in agony.
Both the bastard and I were so surprised by Katsuki's action that we merely stared at the knife she had used to stab him for a good few moments. Even my rage had retreated back into the deeper parts of my head.
Katsuki then grabbed onto the hand that her father was using to stab her with his dagger to prevent him from leaving, just so that she could continue stabbing at his stomach repeatedly.
