The girl gritted her teeth as she realized that the creature hand managed to bite down on her arm. Her hand was ruined, and soon enough the entire forearm had vanished into the creature's mouth. The prosthetic was her lead arm, the girl was left-handed. And yet... it would be easy enough to replace, and given the danger these two foes possessed... The girl's free hand snapped to her knife and drew it in one smooth motion, before scything it down on the joint of her prosthetic arm. The blade lodged itself in the synthetic limb's weakest point, and the girl managed to force the knife through the gap and sever the limb entirely. There was no pain, her left arm could not feel pain. The limb smoothing detached and, as the girl spotted the woman's arrows, she stowed her knife and drew her pistol.

Her movements had to be perfect. Kicking off the ground she backed up and leaped into the air, bringing her pistol up in her remaining hand, her right. Aiming to clear the swarm of small creatures, she fired, repeatedly... and beyond all likelyhood, each shot hit each arrow perfectly. It wasn't possible, she was in the air, she was firing with her weaker hand... how was it possible that her aim was so perfect? The girl's right hand was even shaking!

She landed, having cleared the ring.
