A phantom thief queen—whose age and gender are unknown—flies around the world on an airship in search of treasure. A gemstone the queen had their sights on is stolen from them by a mysterious circus troupe, and a game soon unfolds between the queen and the troupe's magicians, hypnotists, and other members wielding special abilities.
After arguing about whose fashion sense is better, Takaharu and Kinji go outside with their costumes to be judged by the public. Expectedly, they are laughed at due to their outrageous costumes. They then notice a dark aura surrounding several stones, which Kinji depicts as Hyakki Yakou, an event in summer where a hundred Youkai would revive and destroy the town at night.
