The Saint Beast OVA doesn't have much of a plot. We see how some of the characters meet and learn about their overall personalities. There are a few scenes thrown in via flashbacks or dreams that don't fit too well into the story if you've only watched the OVA. On the plus side the art is very good and the slice of life style of the ova can be somewhat alright, though not enough to be considered a decent plot. It's basically just eye candy, pretty men hanging out with their friends.
