Doraemon: Nobita to Mirai Note

Nobita and his friends accidentally use Doraemon's Future Notebook while preparing a school project about energy, making their drawings of an ideal future become reality. Their careless wishes distort the future so badly that even Doraemon's existence is endangered.

Stranded after the timeline changes, the children must use geothermal, wind, and solar power to restore Doraemon and undo the damage, discovering why the future depends on how people choose to use energy today.
