When Misaka and...others...get sent back in time, what will happen? I'm sure you can guess ;) Rated T Just in case.
When Shawn misleads them due to a "map failure", they end up in a strange town where all is not what it seems. Shawn notices nothing out the ordinary until he meets a strange deputy. Because NO ONE, is that happy. (Rated T for muuurrrdeeerrr (murder)
