After wondering why there hadn't been new updates to the english versions of Blood Alone, i found out that the manga was dropped from the Evening magazine it was on a while ago. Author will supposedly finish it out in doujinshin but this likely means than an official english version will never make it here.
I'm kind of sad about it. This and Hayate x Blade are pretty much one of the only manga i still follow. Bummed.
Oh well, it was a pretty good understated little story. Interesting characters and vampire lore too. Hopefully i learn Japanese one day to the point where if he does finish the series through doujinshi, i can see the end to this story.
The last chapter for Spirit Circle just came out the other day. Really good story.
Crunchyroll picked this series up, so if you have an account there that would probably be the best way to read it. I usually use kissmanga or batoto but they have several chapters missing. Mangafox has the entire thing but the pages are shrunk down and have watermarks.
