Sleepy Princess in the Demon Castle 6

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. 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 Quilladillo's 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).
