Sleepy Princess in the Demon Castle, Vol. 15

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 sun shines on the Demon Castle…but it’s supposed to be perpetual night in the demon world! Then Zeus—Poseidon and Hades’ little brother—joins the Demon Castle staff. Everyone is in awe of him except the princess, who quickly finds ways to use the most powerful of the mythological gods to help her achieve her personal goals—sleeping better and opening a cat cafe. Then, in a stunning reversal of fortune, an important castle resident is taken hostage! Will Syalis help or hinder the rescue team’s efforts?
