Dai Nana Ouji ni Umareta Kedo, Nani Surya Ii no?

Sometimes, but quite rarely, there exists cases of people who possess memories of their past life. For example, you may recognize a city you have never been to before, know how to operate an airplane you have never seen before or even know a nickname that only the family of a dead person would know. And that is something that usually happens in the same world, but sometimes as if it was on a god’s whim, a soul with a memory of another world can cross the boundaries between the worlds.

And right now, a child with such a rare soul was born in a country in the middle of the continent. His name is Raymond and this is his story.
