Summer vacation has arrived! But so has Bendelio's distinctive face and a ruthless string of recordings. After surviving a magivision schedule from hell-bonds with her crew having deepened along the way-Nia gets the opportunity to spend the last days of her vacation on the Altoire royal family's private floating island with Relia and Hilde. Swimsuits, barbecues, training, and at long last, a dungeon waiting to be conquered. A vacation it may be, but that doesn't mean the Merciless Maiden will pass up the chance to go wild!
