He is the father of Black☆Star and the leader of the infamous Star Clan. Much like Black☆Star, he was very bent toward being the best and winning every battle. 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.
