Re:live - Starting a new life as a former Corpse God in another world

The Corpse God, a feared entity in his old dimension, once was a little child like any other yearning for his mother. His final spell against the hero transferred his soul to another world, the world to which his mother once fled. In the original story Corpse god would appear in an alley in Japan, but in this one a little quarter-elf boy wakes up in a snowy forest changing the constantly rewritten story of the world of Od Laguna for the better or for the worst. While the whole world is in uproar because of the new arrival, Corpse God only wonders why this whole world seemingly hates his mother.Hi, this is my first story and English is not my first language, any kind of advice would be appreciated. Enjoy.Possible spoiler warning for both fandoms, I do not own either of them.
