One of the first yuri mangas to have ever been published was "Shiroi Heya no Futari" back in the early seventies. Here is a link to the first (and only) volume of the manga. It has a nice story, however, it is quite heartbreaking.
This is just a drabble about Болталка yuri stuff, and my first ever fanfic on this topic, so please don't flame at me. I'd prefer it if Ты just commented. I do not own Vocaloid, I only own the characters Mura, Shinrai and the plot for this story.
