Kouki has found himself reborn, together with many of his past-life memories, in an alternate version of Japan. "There's are no magic or elves?! Then what's the point of being reborn in another world?" It seems a little disappointing at first, but somehow his childhood sketches inspire his mother to develop a revolutionary new theory that changes the world forever. This sets into motion a series of misunderstandings that has everyone believing that Kouki is the real genius behind all of the incredible new technology that his mother is rapidly developing. As a result of his apparent genius, Kouki is forced to give up on his peaceful school life to attend the International Science and Technology Academy, where he meets a beautiful Canadian girl called Alice Alford, a robotics engineer named Shingo Saitou, and an expert on space exploration named Megumi Aikawa. Surely, he can't still continue being mistaken for a genius while surrounded by these real geniuses?! Every time Kouki...

After being reincarnated in the future, Kouki Arakawa continues to live out his life in Japan while being mistaken for a genius.

Using his (mom's) technological expertise, Kouki comes up with a plan to trigger an explosion of subculture. But why would a shadowy Russian organization known as "New World" be working against him? "Shingo, we're about to trigger the dawn of a new age. Let's create new culture!" "Kouki... I don't know what you're talking about." The misunderstandings are happening in Russia this time?! The sci-fi comedy continues in volume 3!

When Kouki and friends visit a lunar base, he inadvertently unlocks the secrets of an ancient alien civilization! Then, to protect her son's freedom, Miki executes Project Ark. Now Kouki's the messiah in another world?!
