＜The clue is the "mysterious part" dropped by the mysterious sculpture＞
One night, a strange incident occurred at the Sapporo Art Park, where 74 sculptures stand quietly. The entire open-air museum was suddenly enveloped in a dazzling light, and one sculpture was sucked into the light and disappeared without a trace... The next morning, a never-before-seen "mysterious sculpture" appeared in place of the "disappeared sculpture," causing an uproar in the Art Park.

It began to move as if it had a life of its own, talking to the other sculptures and singing songs, but the moment the staff of the Art Forest approached to try and get it to talk, the child got startled, dropped a "mysterious part," and disappeared somewhere in the museum. At the same time, you were visiting the outdoor museum. For the sake of everyone in trouble, you decided to use the "mysterious part" that the "mysterious sculpture" had dropped as a clue to find out the truth behind this strange incident.
