Stiles is no longer-
in fact, he's been neither of the above for a very long time.
Stiles has had enough, sick of hiding his true identity- so when his supposed pack make a decision to kick, 'weak, defenseless Stiles,' from their pack; Stiles decides it is time to return to his O R I G I N A L ways.
Or so he tries, it seems that not only does bad luck follow the pack, it also follows Gemin Mikaelson, Original Ripper with a twist.
I have borrowed the ideas of author, @-captivity and followed some of the plot in her novel, The Orginal Ripper; I suggest that you should also go read her amazing book as that is where the orginaility of this novel is based.
Based around Season 3B of Teen Wolf, with Stiles becoming the Nogitsune, it also includes (not in chronological order) episodes from Supernatural, The Originals, and The Vampire Diaries and said characters.
