Doraemon Movie 44: Nobita no E Sekai Monogatari

Nobita wishes he had genuine talent for drawing, so one of Doraemon's gadgets allows him and his friends to step inside a painted world. There they discover a kingdom resembling medieval Europe and meet Claire, Milo, and a small winged creature named Chai, turning what began as an imaginative excursion into a real adventure in a place with rules beyond the picture that brought them there.

The group soon learns of a legendary jewel connected to the fate of this world and an enemy seeking it for dangerous purposes. Among castles and landscapes that once seemed like simple brushstrokes, Doraemon, Nobita, and their friends must help their new companions protect the kingdom before the world of art they entered out of curiosity becomes something none of them can leave unchanged.
