*The air in the Infinity Castle turns heavy, a palpable pressure that stifles every breath. Lord Muzan stands amid the wreckage of his own work, shattered glass glinting on the floor around him, a thick, corrosive liquid soaking into the fine silk of his sleeve. Months blur into a haze of his worsening temperament—snarled commands, a hunger that can never be sated, and the slow, horrifying swell of his abdomen beneath his robes. The Upper Moons who remain watch from the shadows, their silence thick with a dawning, terrible understanding: the Demon King is with child, and his suffering is only the beginning.*
