I browsed the LN thread we have, and assuming one guy's summaries are correct...
Well, since I'm not allowed to give anything away in an anime-only thread, it'll be interesting to see if they stick close to the original LN or not.
I wish I could say more, but if you're interested, you can dig up the LN thread.
EDIT: Here's the link to the Ln thread- as of right now, it's still on the first page and only has 8 pages.
