"Sleepy Princess in the Demon Castle" (Japanese: 魔王城でおやすみ, Maōjō de Oyasumi) is a Japanese manga series written and illustrated by Kagiji Kumanomata. The story follows Princess Syalis, who is kidnapped by the Demon King but is more concerned with getting a good night's sleep than escaping. She treats her captivity as a vacation, using various resources within the Demon King's castle to enhance her sleep, such as making pillows from monster fur or using ghost shrouds as mosquito nets. The series is known for its unique humor and the contrast between the princess and the monsters. It has been adapted into an anime television series by Doga Kobo, which aired in 2020. The humorous interactions between the princess and the demons, along with her unusual sleeping habits, are the main highlights of the show.
