Amakawa Haruto, a young man who died before reuniting with his childhood friend who disappeared five years ago. Rio, a boy living in the slums who wants revenge for his mother who was killed when he was five years old.

Earth and another world. Two people who have completely different backgrounds and values, but for some reason, the memories and personality of Haruto who should've died resurrected in Rio's body.

As the two are confused over their memories and personalities fusing together, Rio (Haruto) decide to live in this new world.

For some reason, along with Haruto's memories, Rio awakened an unknown "special power," and it seems that if used well, he can live a better life than he does now.

But before that, Rio encountered the princess kidnapping incident of the Bertram Kingdom he lives in.

Saving the princesses, Rio was accepted into the state managed Royal Academy. Being an orphan in a school for nobles, it was an extremely destestable place to him.
