>>32I personally would say that my dream for season 3 would be a very solid ending to the story. Let's face it, there will never even be a chance for season 4. So if season 3 happens, I would prefer it to cover them arriving to Yoitsu, finding Holo's homeland, them getting married, buying a store, and having kids. This is obviously a lot, but some parts would be okay to skip time to get to, like after they get married skip to them being in their store with a little wolf girl running around, then darken screen & the end. I haven't finished the books because I am poor, but I am on 13 and can say that there is a lot of crap side-stuff that should NOT be in the next season. Some side stories are good enough to make 2 special episodes, but besides that it should be fairly to the point and wrap up the series.
I think an OVA would be great for following up the third season if it happens, and a side story would be the logical thing to make it on.
