I Was Reincarnated From a Sci-Fi World, and When I Used All My Past Life’s Super Technology for Entertainment, It Became a Huge Hit

Synopsis:

Far in the future.
After ending a 37-year war between humanity and a multitude of machine intelligences, a genius engineer died.

A weapons developer and ace pilot, a man hailed as humanity’s hope, he awoke to find himself reincarnated as a baby in modern Japan.

There was no quantum computing. No anti-gravity. Not only were there no spaceships, but rockets still ran on chemical fuel.
At first, he thought he would be bored in such an outdated world. But this world had things that his previous life didn’t have. Anime. Manga. Games. Movies. Music.

People who were serious about making things, not to kill anyone or save humanity, but simply to entertain others. “…I want to make them too.”
However, the technology that was commonplace in the future was not commonplace at all in the present. This is the story of a genius who saved humanity, and in his second life— this time, he will make as many fun things as he wants.
