Isaac's grin widened as one of the Grimm's heads was cleaved from its body, "Guess the other one is mine then" he said before rushing forward with his weapon raised. The King Taijitu, to its credit, managed to take its focus off of the horrendous pain it was in long enough to shriek at Isaac and strike at the hunter to be. Isaac grinned and dropped to his knees, using his momentum to slide on them as he ducked under the creature's maw. Isaac sneered as he brought his weapon up and dug into the soft underside of the massive snake. Fría cut in deep, and with the Taijitu still in motion, the weapon slit the creature wide open from neck to stomach, leaving jagged pieces of ice in the wounds. Isaac rolled to the left as the Taijitu rose up and shrieked in pain, it's blood splashed out, and would have likely been followed by its organs had they not been stopped halfway out of the body by the rapidly freezing wound. Isaac stood and waited patiently as the beast writhed and fell to the ground before walking over to the barely living white head and uttering two words; "El fin.". The hunter raised his weapon and swung hard, digging it into the remaining eye of the white head and rendering the red orb and part of the brain behind it to a pulp, effectively ending the creature's life.
