As children, we all watched anime, films or TV series about superheroes. Almost all of us dreamed of becoming like them — saving people, fighting evil, being strong and invincible. But over the years, most people forget these childhood dreams or lose faith in them.

Futaro Yukimichi is a schoolboy for whom this dream has become the meaning of life. He was not going to give it up, even if the whole world called him naive. After all, there are dreams that remain just dreams forever...

But one night, everything changes. Futaro finds himself in a world of magic, where he is destined to become a true hero. And it is there that he gets the chance to fulfil what he has dreamed of all his childhood.
