This recap episode is not available in the US. It comes right after episode 12 in the anime and has no new footage. The only "new" things are a narrative that is overlaid between the dialogue that is already in the show and an extended version of Lindel's magical song (which is absolutely beautiful and can only hear if you have the OST). I wouldn't say it is a must watch for even the most die hard of fans of the show as there is nothing new to gain from it. As an individual episode disconnected from the rest of the series I am honestlynot sure how to rate this.
