Another milestone for the Demon Castle is (unintentionally) celebrated with surf, sand, and sun. Quilladillo discovers the hidden costs of fame, while Vampire discovers the incredible power of normalcy. A quest for a free pillow goes awry when a brief trip to the home of the Divinities results in Princess Syalis and Poseidon coming face-to-face with Somnus--the god of sleep. Plus, river races, idol groups, Angel Teddies, part-time jobs, and the Demon Castle residents like you've never seen them before!
