Sleepy Princess in the Demon Castle 5

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 comes to the surprising conclusion that being good will earn her a good night's sleep! But none of the demons trust her sudden transformation. The princess's latest dilemmas include a growing urge to use the bathroom when it's out of order, her pet Eggplant Seal outgrowing her quarters, and growing into a giant instead of up. And then it's time for the castle's Hostage Reeducation Week... Plus, a visit to demon preschool!
