A captured princess just wants a good night’s sleep! Shhh...
Kidnapped by the Demon King and imprisoned in his castle, Princess Syalis is...bored.
Princess Syalis manages to mess up Christmas and Valentine’s Day...again. Then, when Syalis and her demon captors pay a visit to her kingdom of Goodereste, a demon stands in for the princess...and winds up needing to be kidnapped herself! A common enemy forces Syalis and her archnemesis Poseidon to team up. And Syalis messes up more things, including a Demon Castle hot-pot party and a Demon King educational biopic. But she still manages to find some good opportunities for relaxing naps...
