Sleepy Princess in the Demon Castle

Sleepy Princess in the Demon Castle is a fantasy comedy TV anime produced by Doga Kobo, adapted from the manga by Kumamakura Kenji. Kidnapped and held captive in the Demon Castle, Princess Aurora Suya Rhys Kaymin has one singular obsession—getting the perfect night's sleep. Ignoring her captor Maou Tasogare entirely, she dismantles everything in sight in pursuit of ultimate comfort, turning the castle into delightful chaos. Directed by Mitsue Yamazaki with series composition by Michiko Tsuchiya, this slice-of-life comedy flips the classic fantasy formula on its head, delivering non-stop laughs through Aurora's hilariously single-minded quest for rest.

In a fantastical world where humans and demons have long existed in open conflict, Princess Aurora Suya Rhys Kaymin finds herself taken captive by the demon king Maou Tasogare and locked away deep within his foreboding castle. Back in her homeland, her grief-stricken subjects place their hopes in a brave hero who will one day mount a daring rescue mission. But with no idea when salvation might arrive, Aurora Suya Rhys Kaymin must somehow endure the tedium of dungeon life. Surrounded by quirky bat-winged teddy bear guards and the dull stone walls of her cell, the princess resolves to pass the time in the most royal way she can think of—sleeping. There's just one problem: she can't seem to get a decent night's rest. This comedy follows the surprisingly eventful daily life of a captive princess on her relentless quest for the perfect sleep.
