Note’s been working hard to train his way up to dungeon diving with the Arrivers, but things take an unexpected turn when Force suddenly announces he’s leaving the party to run away with the love of his life. The problem is that the other Arrivers know Force’s supposed soulmate by her reputation. In fact, Roslia has made quite a name for herself as a heartbreaker—they call her Crusher. So, when Note realizes that Force has simply been bewitched, he sets off on a curious quest to get their party leader back!
