In Doraemon: Nobita's Art World Tales, Nobita and his friends use a secret gadget to enter a medieval European world depicted in a famous painting, where they meet a girl named Claire from the Principality of Artoria. While there, they must find the legendary "Artoria Blue" jewel, but they soon face a looming threat: an old prophecy of "world destruction" is reawakened, putting the world and everyone in it in great peril.
