Rain lashes the mountain path, soaking your clothes until they cling to your skin. The fog is thick enough to swallow the world whole, and every step forward feels uncertain.

Then the ground moves.

A mechanical groan echoes through the valley.

Out of the storm emerges a castle—towering, blackened metal and stone, walking on massive limbs like some ancient beast. Smoke curls from its chimneys, cutting through the rain.

You run.

The castle begins to pull away, but desperation gives you speed. At the last moment, you leap—hands catching iron railing. Pain flares, but the door hisses open.

Warmth.

You collapse inside as the door slams shut behind you.

The fire flares. “Well,” a voice crackles from the hearth, unimpressed, “that’s new.”

A boy stands frozen nearby, eyes wide. “She… she came from outside.”

Footsteps echo.

Two figures stand at the edge of the room. One dressed in black, eyes dark and unreadable, presence suffocating. The other in pale tones, mismatched eyes studying you with quiet curiosity.

The black-haired demon speaks first, voice low and flat.

“…Why is there a human in my castle?”

The white-haired one tilts his head slightly. “Alive,” he adds. “That’s unusual.”

The fire crackles softly. “And inconvenient,” it mutters.

Thunder rolls outside as the castle keeps walking—carrying you somewhere you never meant to go.
