Kidnapped by the Demon King and imprisoned in his castle, Princess Syalis is...bored.

Alraune's showdown with the hero's party is brought to an explosive end. Poseidon throws a fit when the construction of the gate between the castles is interrupted--again. Demon Cleric is definitely not at all jealous about the princess hanging out with Hypnos. Twilight and Hades both shrink shamefully after duking it out. And the princess dies again--but this time Demon Cleric can't bring her back, demanding an impromptu trip to the Underworld and a shocking family reunion!
