[Machine Translation] Hakone Elementary School is located in one of the best hot spring resorts in Japan. Kito, Akari, and Moyoyo, who are in the second class of the sixth grade, are opposed by their teacher to having "espionage" as a theme for their integrated studies, so they secretly begin researching the "spy way of thinking and seeing things" as a back-up integrated studies project. Then, the perfect "target" for their training appears before their eyes... A neighborhood mystery that will make your heart pound!
