What will happen to Nobita's life after Doraemon leaves?

Nutty Boy is an out-of-the-box kid with big ideas who loves involving everyone in his adventures — even though they don't usually go as planned!

After bringing a fossilized egg back to life with the Time Cloth, Nobita finds himself the owner of a baby dinosaur. Everything is fine until it grows up. Nobita and friends use Doraemon's time machine to return it back to its own time.

Sisters Fû and Rui, who used to be close, but have been a bit distant from each other recently. One day, Fû encounters a mysterious spaceship and gains magical powers. At that same time, Rui also gains magical powers, and both transform into the adults they dream to be. The sisters' powers come with two conditions: their magic powers can only be used in one year, and no one must know about it. Unaware of each other's secrets, Fû and Rui become active as idols.
