actually Zrozex, a Shinigami is an actual creature from Japanese mythology, but it's like claiming he's fallen angel or the Grim Reaper. i don't know if it appears in Bleach [couldn't make it to episode 3 of that series] but it's the creature in Death Note that helps the main character. [which is a series i did watch. preferred the live action movie's ending though]
wow is all i've got to say to your claims. the belief a great war is going to break out isn't new, people have talked about this for a few years i've noticed. the claim you're a werewolf and shinigami though makes you completely uncredited in my books. if you claimed something like you had a wolfs spirit, or it was your spirit animal, then i might of given you some footing, but your profile is 100% fluffy non-sense or copy/paste chain mail. i know you're going to get angry with me, but it's true. if there's a war that happens between gods and humans, i'll apologize, but that's a pretty big if.
