He hears beeping, heavy breathing—after his fist connects, that is, which sets him a little more at ease. If he can land a hit even in this darkness, he's not at a total loss.

Speaking of the darkness, Shin tries again to blink, but nothing works. Even the flurry of movement he can hear happening in front of him (but at a safe distance) can't be registered.

A suspicion rises in his mind. Shin turns his head toward the beeping, and... nothing still. He brings his hand to his face, then nearly pokes himself in the eye in his attempts to see his fingertips.

Ah, dammit. He really can't see right now. Shin scowls mightily before turning his head back toward where he thinks the beeping is coming from.

"Hey, you there. Who are you?"
