I can't remember the name of this anime

It was very bizzare, but I think I found it on animesuki years ago.

I'm trying to find it, but I vaguely remember much about it. It was a very bizarre anime. I think somewhere I read that it was classed as a yuri type anime or something. I don't know. In the beginning of the first episode there is a girl running from soldiers or men and she's carrying some box or briefcase with a needle shot in it. She manages to hide from the men and takes out the needle and sticks the thing up her c*nt or at least it looked like that. Whatever was in the shot made her not human anymore. Later on the episode or next episode she can be seen trapped inside a large crystal and if anyone disturbs this crystal then a large monster will burst out of it and attack. This anime is set in an era with knights and swords. Kinda like back in the medieval days. I think the main character is a knight lady who sets out to destory these weird monsters that appear.

Anyway, that's all I remember. this anime is old, but not very old. I think it came out somewhere in the early 2000s years.
