Evangel is talking about the current filler arc. He is talking about the Zanpakuto of the shinigami refusing to take orders from the shinigami any more and starting a war to subjugate the shinigami because the man called Muramasa has set them free. Doing something like that sounds rather large and out of league seeing as we are just getting out of the academy. We'd all get pretty well beat up by our own Zanpakuto or whatever.

Not really sure why its a problem to do a character arc now, but that aside. Thought you were going to do one of the missions before we got into the character arc. But you want to a story arc that's not focused a single character. Well that's easy enough manage. How big of an arc? Because we can take this a long way or make it really quick depending on how much effort goes into it.
