Sleepy Princess In The Demon Castle Vol. 12

Syalis is a cute princess. Like, really cute. And she’s been captured by the Demon King and imprisoned in his castle. How boring! In order to pass the time, she decides to partake in her favorite hobby: sleeping! But getting a good night’s sleep inside a demon castle is harder than it looks, and her demon captors won’t even treat her like royalty. Talk about rude! But no worries, she’ll scheme her way to getting a blissful slumber by any means necessary, like making a pillow out of the fur of her hapless Teddy Demon guards for starters!
In Vol. 12, the Demon Castle is in a financial crisis and Princess Syalis tries to help them weather the storm. Plus, M.O.T.H.E.R. creates a mecha based on the most fearsome resident of the castle and Syalis must pilot it in battle against hero Dawner who is determined to rescue her!
