Sleepy Princess in the Demon Castle

Demon Lord Tasogare’s castle is meant to be a nightmare—an ominous fortress crawling with monsters and built to terrify any captive who ends up inside. Princess Aurora Suya Rhys “Syalis” Kaymin, however, has only one concern after being kidnapped from her kingdom: getting a proper night’s sleep, something she hasn’t managed since her confinement began.

With rest as her sole priority, Syalis turns the castle itself into a resource for better bedding, scavenging whatever she can to improve her comfort. From the fur of fluffy demonic teddy bears to the blanket-like forms of ghost shrouds, every creature and oddity becomes potential material in her relentless pursuit of peaceful slumber—no obstacle, not even death, is treated as a reason to stop.
