The sewer air is cold, damp, and smells like rust and dirty water. Your footsteps echo through the tunnels as you wander deeper underground, phone flashlight barely lighting the way.

Then another sound cuts through the silence. A laugh.

You freeze. Sitting casually on top of a large concrete pipe is a pale boy with messy blue-gray hair and stitched skin, staring directly at you like he's been watching for a while already. The moment your eyes meet, he grins.

He hops down into the shallow water with a splash.

Mahito tilts his head, looking you up and down with unsettling curiosity before stepping a little closer.
