Sleepy Princess in the Demon Castle, Vol. 6: Volume 6

A captured princess just wants a good nights sleep! Shhh Kidnapped by the Demon King and imprisoned in his castle, Princess Syalis isbored. Accompanied by an entourage of demon guards, Princess Syalis takes a field trip to the human world to acquire a special pillow. Then she receives several invitations from her demon captors: first, to replace the cooks who have succumbed to heat exhaustion in the Demon Castle kitchen (somebody needs to make Quilladillos Monster Bird Egg Custard); second, to attend a pajama party (despite being woefully ignorant of the concept); and third, to design a new area for the hero to explore (which turns out to be the exact opposite of what the demons commissioned).
