No critical review, just a synopsis: Basically this is an omake for Azmaria fans as well as an educational series about what goes on about the plot. It gives a lot of background of the time period, Catholic mysteries, and fictional elements associated with these series. I find this useful, not because I didn't know about the information present, but I was able to show my fellow viewers this guide so that they could understand better. Since I'm obsessed with pre-WWII history and I go to a Catholic school, I know what was going on throughout the series, but I know many people who watch anime maynot understand the context in which the series takes place or the mysteries surrounding the series. This guide is useful for the above specified reason.

Watch this only if you're an Azmaria fan or if you are curious about certain details within Chrno Crusade.
