I do not believe it is the edo tensei, precisely. Those who Akatsuki disturbed... they acted under a central control. While the figures I encountered, they seemed to be moving independently, targeting anyone who still had a rational mind, even their apparent allies. Yet they had that same look... of being dead and alive at the same time. It gives me cause for much concern. Yet I realize that... perhaps similar strategies could be helpful in dealing with these enemies.
