Sleepy Princess in the Demon Castle, Vol. 30

By Kagiji Kumanomata

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.

The fun as well as the nightmares continue as the plague of dreams becoming reality continues to spread But whether it's facing down your dad as the boss of a dungeon, accidentally unleashing another round of (even more widespread) gender-bending, needing to shop at the pricey supermarket, or just having all your work friends bail on you, no nightmare can prepare the Demon Army for the terror that is the accidental arrival of the hero Dawner in the heart of the castle
