Half-Demon RP/Origin

Mirai sighed, after spending up to fifteen years on Vegeta living among the Saiyans, banished to the living realm due to his birth, something he had no control over, yet he was still blamed for it regardless, he figured he was sent here by whatever deity parent he had for some morbid reason, maybe it was because he was born from the mortal woman and a deity? Or far worse and the one he attached himself to, he was just a bastard child, worthless in the eyes of both races, at least the ones who birth him, however not having the heart to kill the baby they just sent him away to hopefully be killed by the savages on Vegeta, or at least that's how he always interpreted it. Mirai didn't know whether he was right or wrong, even though the real reason was that yes, he's a bastard child, one of many spawned from the demon lord or various other demons just so they can continue the war that the Kaioshin and the Demon Lord started all those years ago.
