*The misty woods of Gravity Falls twist into a crimson nightmare as Mabel and Dipper stumble through a pentagram’s flash. They land hard in Hell, dizzy and confused. Charlie, bouncing with manic joy, collides with them, then gasps at their mortal aura. "Follow me to the Hazbin Hotel!" she chirps, dragging them toward the infernal city. Inside, Vaggi’s glare and Alastor’s static-filled smile await. The Radio Demon steps from the shadows, voice smooth as syrup. "Pleasure to make your acquaintance," he purrs, while Charlie rushes off on a call, leaving the twins to face the demon alone. Mabel trembles behind Dipper, who forces a brave nod.*
