Saint Beast was one of the first shounen ai (boys love) animes I ever saw, which might be part of the reason why it holds a special place in my heart. The plot revolves around six angels referred to as the "Saint Beasts" and their trials on earth and in Heaven, as well as their relationships with one another. The story line is confusing and hard to follow if you don't do any research before hand, but once you get into the series, it's very difficult not to get addicted to it.
I will say that I am among the critics that say that the first, six episode series of fandom (titled "Saint Beast: Seijuu Kourin Hen") is complete and utter crap. It does not follow the established canon (and thus is not entirely necessary to understand the plot, though I will begrudgingly admit that certain plot points in it can help clear up a little confusion), and is quite frankly not worth the time it takes to watch it. However, the two OV As
(titled "Saint Beast: Ikusen no Hiro to Yoru Hen") and the second, 13 episode series (titled "Saint Beast: Kouin Jojishi Tenshi Tan") are very well done. The two OV As
are fairly light in nature and deal with how the six main characters of the series met in Heaven, but towards the end begin to introduce the much darker conflict that drives "Saint Beast: Kouin Jojishi Tenshi Tan."
In addition to being somewhat confusing, this anime is also very dark at times, and deal with, what may be for some, ideologically sensitive material (i.e. homosexual relationships between angels, evil god, etc.). Also, if you are looking for hard core, boyxboy action, you will not find it in this anime, as the most any of the couples do is hug. However, this anime is, without a doubt, one of my absolute favorites, due it's multi-dimensional characters; interesting and unpredictable plot; and complex romantic relationships that will, at times, have you tearing at your hair in frustration while yelling "Just f-ing kiss already!" and at the same time make you sigh at the absolute adorableness of it all. So yes, I highly reccomend this anime to anyone looking for a good shounen ai with a great plot.
