Synopsis

Ran and Conan enlisted the Detective Boys for a restorative trip to an onsen in Kinosaki, Hyōgo, hoping the warm waters would ease Conan's sprained ankle. While enjoying the traditional bathhouse, Ran encountered a young girl named Haruna, who was traveling alone. Compassionate as ever, Ran took Haruna under her wing, guiding her through the charming town of Kinosaki, oblivious to the presence of a watchful stranger who seemed to be following them.
