@DBZ_universe: Perhaps, but since almost everyone has darkness in them somewhere, survival would be rare. The exception is people like Goku or yeah babies lol.
And I would choose an American name. This is because in the majority of anime/manga, the characters' names have meanings that have something to do with who they are and since I wouldn't know what Japanese name to give my characters so Ill just stick with English lol. Or maybe a cool made up name like neon or mars.
What about your characters?
