Back at the Ice Brood Mother, the fight finally reached its end, and the one to fall was Gojo. His lungs had burned, and he couldn't breathe anymore. With his mana regeneration suddenly being cut off, his thunder step spell failed, he couldn't maintain his mental defences anymore, and all of his offensive magic crumbled into nothing.
Between a titanic monster body or a small and fragile human body, it was an obvious end that the human would be the first to crumble under stress. Even though Gojo already knew that fact, he didn't want to see it come or happen.
The moment he slowed down, the Ice Brood Mother smacked him out of the sky into the ground, took her humanoid form, and landed on his chest with a bite. She had been waiting for this moment. It had been a while since she understood that she couldn't defeat Gojo directly; he was too nimble and cunning to be hunted, so she had to endure his assault and wait for the right moment to bite him.
