Shihoko Hagino

Sewashi and Doraemon find themselves way back in time and meet Nobita. It is up to Doraemon to take care of Nobita or else he will not return to the present.

A sapling Nobita discovers is turned into a plant-boy with help from Doraemon, and becomes Earth's only hope at passing judgment from the dryadic aliens of the Green Planet.

During summer vacation Nobita picks up a small rocket containing Papi, a palm-sized alien president escaping rebels on his home planet Pirika.

Upon hearing about the story of Treasure Island, Nobita dreams of discovering and exploring his own treasure island, despite the fact all of the Earth has been mapped already.

Nobita, Doraemon, and the rest must come to the aid of mermaid princess Sophia, whose undersea kingdom is suffering under the weight of a war. Their only hope lies in a mythical sword from the planet Aqua...

Nobita wishes the world into a magic-reliant one with Doraemon's Moshimo-Box, and, along with his friends, must stop an asteroid from hitting the planet with help from a sorcerer-in-training.
