Naruto: Change the Ninja World with Doraemon!

The Third Ninja World War broke out, and the entire ninja world was shrouded in flames of war and conspiracy. Major ninja villages fought with each other. Countless ninjas fell on the battlefield. History is slowly moving forward on its established trajectory. However, a young man who did not belong to this world quietly appeared in this era. Deki Sugi Hideai was originally just a genius boy in the ordinary world, but after an accident, he traveled to the world of "Naruto" and came to the most chaotic period of the Third Ninja War. And coming to this world with him was Doraemon, a robotic cat from the 22nd century, and the four-dimensional pocket filled with future technology. When future technology meets the chakra system, when absolutely rational geniuses begin to deduce war. Will the history of the ninja world continue to develop according to its original trajectory? On the battlefield where countless ninjas are fighting to the death, a "behind-the-scenes player" who relies on wisdom and science to change the situation is quietly appearing. This time, what has been changed may not be just a war.
