On the night of a Halloween event, three childhood friends enjoy the festivities in costume while the whole town joins in.
A modern world where magic does not exist, but beastmen and humans coexist. In the town where Guest, the dragon-kin Yuto, and the wolf beastman Rouya live, the Halloween event has arrived! The three head to the town square where the festivities are being held. While enjoying their respective costumes, they deepen their bond through interaction—getting treats, playing pranks, and sharing moments that will become precious memories. Tonight, who will be pranked, who will get treats... and what kind of memories will they make?
