Sleepy Princess In/demon Castle Vol 30 By Kumanomata, Kagiji

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 and the nightmares continue as the plague of dreams that become reality continues to spread! But whether it’s facing down the boss of a dungeon (who’s also your dad), accidentally unleashing another round of (even more widespread) gender-bending, needing to shop at the (really expensive) supermarket, or just having all your friends (from work) bail on you, no nightmare can prepare the Demon Army for the terror that is the accidental arrival of the hero Dawner straight into the heart of the castle!
