Mia stripped off her protective suit, mouthguard, and gloves.
As she shed her clothing, smoke burst from every angular joint of her body, even from the corners of her eyes and the spaces between her hair, swiftly forming into the bizarre shapes of hounds.
As the forms steadied themselves in this world, they realized... the person was gone?
Mia had already dashed forward, her shadow wildly flailing beneath her feet like a windshield wiper. Whether it was a wall, a door, or objects like cabinets in front of her, the Shadow swallowed them all ("transporting to the Shadow Realm"), letting Mia safely pass through, then regurgitated them carelessly behind her.
This sudden turn of events left the hounds somewhat unprepared. Although their running speed in this contiguous world was far slower than in the Discrete World (where traversing a billion years/light-years took only about a day), it wasn't something normal humans could easily escape.
