Sleepy Princess in the Demon Castle

Sleepy Princess in the Demon Castle synopsis: The Demon Lord Tasogare's castle is a grim and terrifying place, teeming with an assortment of monsters. Any unfortunate soul imprisoned here is bound to be horrified by the nightmarish surroundings. However, the human princess Aurora Suya Rhys, affectionately known as "Syalis," is an exception. Remarkably unfazed by her predicament, Syalis has but one concern—sleep. Ever since the demon lord abducted her from her kingdom, a peaceful night's rest has eluded her. In her quest to address her dozen dozing dilemmas, the resourceful princess utilizes whatever she can find within the castle. Whether it's the fur of fluffy demonic teddy bears or the silk-like, blanket-resembling forms of ghost shrouds, everything becomes a means to secure a tranquil slumber. With a wealth of potential materials at her disposal to craft sleep-inducing items, nothing can deter the slumber-prone princess—not even death.
