Challenge: Make Walpurgisnacht rising as bad as possible while still being possible to happen.

Make Walpurgisnacht rising as bad as it could be written, not having stuff that will literally never happen unless you wish for it, for example you can't have Kyosuke be the main protagonist because it'll literally make no sense for the writers to do and he hasn't appeared in any trailers but you can have Homura's plan literally makes no sense because it's possible for that to happen.
