Talk:Poltergeist Arc/@comment-24.58.212.193-20130612022125

The trivia section claims that Erii's appearance in the background of an illustration from Index New Testement settles the issue of whether or not the Poltergeist Arc should be considered canon. But this doesn't seem right. It certainly settles that Erii's existence is canon, but it doesn't settle whether the events in the Poltergeist Arc are canon. And even if it establishes that something like the Poltergeist Arc occured as canon, it doesn't settle whether such events occured as they do in the anime.

There's even reason to think they could not have occured as they do in the Railgun anime. The Poltergeist Arc would have had to have occured before August 10th when the Sisters Arc begins. And Kongou Mitsuko appears quite a bit in the anime. But in the Railgun manga, she transfers in before the Fall term, ariving on August 27th (see my comment on Chapter 40 for the rationale for this date). So assuming that the Railgun manga is canon (a safe assumption, I think), the events portrayed in Poltergeist Arc of the Railgun anime cannot be.
