CAA: Christian Anime Alliance

Does anyone know anything about this series? I came across some torrents for it, and it looks somewhat interesting, but I'm wanting to get other people's opinions on it before I check it out. Like, for instance, what it's called in English, rather than just it's Japanese name.

The title could be translated a variety of ways, but basically it says "Yami, the Hat, and the Books of the Travelers".

As for the series...haven't actually seen it. I remember seeing pictures long ago and wanting to look into it, but it seems to be a yuri anime. In fact, I actually think it's an incest yuri anime. Like the whole plot is a girl searching for her sister and lover.

O_o ewwww... (sorry for the brief post, but I came in here to see what was going on and saw that and had to say "ew")

[spoiler]Well the younger sister is adoptive, the attraction is one-sided and the younger sister who feels it is ashamed of herself for it, but since the elder sister has vanished magically, the younger sister is looking for her. This is what I know from the first couple episodes. There is definite, not-so-subtle yuri content, but it's neither the focus nor is it given much physical manifestation.
Having said that, I should note I've only seen the first two episodes, but some web-surfing I did after I had concerns with the opening scene suggested the rest of the series continues in the same way.

I gathered during said surfing that the series is based on an adult game, thus explaining why they felt that they needed such content. The story itself seems to be far less adult.

Note that the scenario might also offend some Christians, due to their recycling the names 'Adam','Eve', and 'Lilith' into a mythology unrelated to our religion.[/spoiler]
