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 by a ferocious attack of fangirlism. Poseidon throws a fit when the construction of the gate between the old and new castles is interrupted--again. Demon Cleric is most definitely not at all jealous about the princess hanging out with Hypnos. Twilight and Hades both shrink shamefully after duking it out. And, of course, 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!
