The ongoing battle for Princess Syalis’s slumber reaches a critical point as she activates the 'Cradle of Silence' deep beneath the Demon Castle. This ancient magical artifact, left by the previous Demon King, forces absolute silence upon the entire fortress. As the ambient noise vanishes, even the heartbeat of every demon is hushed, allowing the Princess to descend into a perfect, undisturbed rest. However, this feat inadvertently halts the castle’s primary magical power supply. Demon King Tasogare is forced to witness the terrifying reality that the Princess’s desire for comfort can overwrite the very laws of physics governing his domain. A haunting hypothesis emerges: was this castle originally designed solely to facilitate the Princess's sleep? While the castle remains paralyzed in the void of silence, a lingering question remains regarding the deep, inexplicable resonance between her slumber and the foundation of the castle itself. As the Princess drifts away, only her faint breathing breaks the quiet, signaling a shift in the delicate balance of her captive world.
