Nobita's Time Heist

When Nobita wakes up, he finds the world drastically altered: technology has regressed by six decades, and all memories of Doraemon have vanished from Tsukimidai without a trace. Through a series of bewildering events, Nobita and his friends uncover a chilling truth—an unprecedented temporal war is underway, targeting a future defined by advanced human civilization. The first dominoes of a catastrophic chain reaction have already fallen, threatening to swallow every era of human history. Their only lead is a single, time-defying photograph. Captured on September 19, 1492, at the churning epicenter of a spacetime vortex, the image shows the back of a familiar blue, cat-shaped robotic nurse. Thrust into a high-stakes, cross-era time heist, Nobita and his companions must piece together scattered clues through the corridors of history, where a vast and sinister conspiracy slowly comes to light.
