[DeepL Translation - needs review] Volume 1 Introduction: Once upon a time, when man and demon existed...
The demon king kidnaps a human princess and imprisons her in his castle.
The people are outraged, and the hero sets off to save the princess!
In her cage, the princess thinks...
There is nothing to do but sleep.
In order to find a way to get a good night's sleep, the captive princess does as she pleases in the Demon King's castle!
A new kind of sleep fantasy comedy!
(Translator: DeepL)
Very entertaining. From a learning perspective, there's a lot of slang and fantasy vocabulary that might throw you off.
Has furigana.
