The story begins when Nobita, known for his laziness and lack of confidence, stumbles upon a mysterious feather during one of his usual escapades. This feather, originating from a fantastical world called Featherplace, serves as a gateway to an alternate dimension inhabited by bird-like creatures and governed by a delicate balance of nature and magic.

Upon discovering the feather, Nobita and Doraemon are transported to Featherplace, where they encounter a young bird-girl named Kibo.
