The Human Created By Pokemon

This is my first attempt at making a Pokemon fic, so sorry if it's bad

Arceus makes a deal with Giratina and, with the help of Suicune, forms a human who is a descendant of them. But this human has no idea who he is, or what the marking on his back is about. Follow his journey through befriending Pokemon, learning about the world, finding his calling and falling in love.
