Nobita’s Space-Time Calamity

When they woke up, the level of technology had regressed by sixty years. In Tsukimidai, all memories of Doraemon vanished into thin air along with the passage of time.

After a series of twists and turns, Nobita and the others learned the truth: an unprecedented, enormous war spanning time and space was underway, and its target was the future, when human technology would flourish. The dominoes hidden in the past had already toppled, and a massive wave was about to sweep over every era of human history. Their only clue was a snapshot that had also crossed time and space.

On September 19, 1492, at the center of a temporal maelstrom, the Time Patrol photographed the back of a blue robotic cat designed to care for children.

That discovery drew Nobita and the others into this colossal heist across time and space. As they intercepted more and more clues in different eras, a huge conspiracy slowly came to light.
