Sylphiette and Rudeus spent many long years apart, but fate has finally brought them back together, this time as lovers. When Princess Ariel asks Rudeus about his intentions, he doesn't hesitate for a moment-he's going to marry Sylphie! What's more, he wants the perfect house for their newly wedded life together. He's got his eyes on a suspiciously haunted mansion. After a little bit of team ghost-busting with his friends, a frightening property might just be the perfect place for love!
