This episode contains a lot of original material. It's more like a complement than an adaptation of the Achiga-hen manga. Normally, I'd like an adaptation to be more faithful to the manga but, let's be honest, there were things in the Achiga-hen manga/anime that were barely mentioned in the beginning, then turned out to be super important. So I think this is good in this case. Just kidding but an anime adaptation of this episode would be nice. ^_^
