The Apocalyptic Devil Is Reborn in the 1990S

It has been three hundred years since the end of the world. I am the big devil who dominates the world. I will take over any job as long as it is beneficial. In an explosion, I, together with the artificial intelligence implanted in my brain, traveled back to the body of an honest kid in middle school. I started a different life, fulfilled my previously unfulfilled wishes, and dominating the world was no longer an ideal. This novel and its characters are purely fictitious.
