That should clear that up. I didn't mean to make any one confused. As for the past sixteen years. Not much happened a few battles with puppets nothing you can't see on the show. Except the only difference Kagome is a demon. Think of the claws Sesshoumaru uses mixed with miko energy and fire. Ouch. O.O that would hurt. Hope I helped you all out.
