In the past, White Star was put into a very similar situation as Black Star in his battle with Mifune. They were both asked by Mifune about which path (path of a Warrior or path of a Demon) they'd rather take. White Star did not answer, but Mifune was easily able to tell that White Star already took the path of a Demon. Black Star simply said he'd make his own path.
White Star was slain in battle by Mifune.
