Today, MangaGamer released a full version of Cartagra ~Affliction of the Soul~ for purchase. Uhh, do you mind if I copy the text I did for the trial post? No? Alright then.
Created by Innocent Grey of Kara no Shoujo fame, Cartagra was actually released three years prior to the release of KnS, its sequel. The English Kara no Shoujo translation was released quite a ways before Cartagra’s, which may have to do with a fan translation project taking it on before MangaGamer’s official release.
Cartagra is set four years before the events of Kara no Shoujo, and you should probably read Cartagra first before proceeding to KnS. Here’s a quick description, courtesy of TLWiki:
The hero of this story is Takashiro Shugo, An ex-police officer that is now unemployed and freeloading at a brothel. From time to time he takes on detective work from his former superior. As the story starts off, a missing persons case is dumped onto him.
The person he is supposed to find is Kohzuki Yura, a girl he had an intimate relationship with before being sent off to war. While all this is being played out, a series of brutal killings occur in the background. As they strike closer to home, Shugo is no longer able to turn a blind eye and is dragged into the spiraling web of events.
If you’d rather not sign up for MG’s site, the trial version can be grabbed here for now. MangaGamer’s own page[NSFW] for the VN has some extra background information if you’re curious. Oh, and you can buy it there for $34.95 ameribucks. Shouldn’t have forgot that part.
