Reborn in Another World as a (Colorless) Demon Prince

He made his break through and proved the naysayers wrong. But just as everything in life was falling into place, he died. A strange being meets him in the in-between, and he is given a second chance at life. The world he's reborn into in full of wonderous monsters and adventures to be had. However, he's not human anymore, but a demon. And not just any demon, but a Colorless prince. Even worse, demons and humans don't exactly...get along. War looms between the two nations, and threatens to capsize his life into chaos and blood. If he wants to make anything of himself, he will need to work very, very hard.  It's a shame he's not sure what to do or where he wants to go. Please note: The story is a slow burn and only starts to pick up after chapter 8. Also, if you like Re:Zero, give this one a shot. It is also a weak to strong story.
