Why does everybody assume the 3 soldiers can't just be human? I keep reading about how they're somebody's heartless, or nobodies, or dis-souls, or souls, or endless, etc... There is no evidence for any of this! Half of those things are not even confirmed to exist, nor is there any evidence that they even exist (dis-soul? endless?). Why does everybody have to make up a theory where they are somebody's something. Why can't they just be 3 new characters? (that are human)
