But one day, his random scribbles leads (his mom) to the discovery of a certain formula, which as a result, leads him to be mistaken as a genius by the entire world.

For that achievement he is sent to the school of prodigies, the State Technology Academy, where he meets the Canadian girl Alice and the robot engineering genius Shingo. And even at such a place, he is still mistaken as a genius?! Every time Kouki shows his knowledge from his previous life, he is mistaken as a genius, and everywhere he goes irregularity follows.

This is the comedic life of a genius reincarnation loaded with misunderstandings.
