Within DxD, as Set sitri

A man died, as he tried to save his twin brother, and a little girl who he doesn’t know, from that flaming hell place. But when he opened his eyes, at first the man thought he is in the void, only to later on to discover, the darkness wasn’t the void, but in fact in the stomach of his new mother, along with someone else. If that wasn’t shocking enough, to be reborn as an unborn baby. Once he left his new mother’s stomach, not only he discovered he also a twin in this new life as well. But he is also a Devil!? What kind of crime he did in his first life, to not be sent to hell! But to be part of it!? And to make matters more confusing… why his is Demonic Power reserves monstrously high, even greater than any recorded High-Class Devil? Not only that, but his physical body also evolving stronger. And his ability as a Sitri, the ability to weld Water, he doesn’t need to train it, he just knows instinctive level, how to weld it… and how to even switch between Water and Ice? Why the *beep* is going on!? - This is a fanfic of a man who never got the chance to read or watch anime, has no clue he is reborn as the twin younger brother of Sona Sitri, and younger brother of Serafall Levithan, in the world of Highschool DxD.
