Sleepy Princess In Demon Castle Graphic Novel Volume 01

"While waiting to be rescued, Princess Syalis is so bored out of her mind that she just wants to sleep away the time. But the Demon Castle is terrifying...ly uncomfortable! What's a princess to do to catch some Zzz's other than fashion a pillow out of her captors and make an air mattress from a sacred shield? Unfortunately, her many schemes can only try the patience of the Demon King and his put-upon minions for so long...right? For teen audiences. "
