I was browsing the site of The Yaoi Review when I encountered this. Togainu no Chi is originally a BL game which will have an anime series in the future. It also has a manga if I’m not mistaken. It seems to have a lot of blood and action in it and apparently not the lovey-dovey shounen ai. ^_^
Here’s the trailer of the anime.
Also, visit The Yaoi Review site for more info and vids.. ^_^
