She looks 100% like Kyouko Karasuma from the manga with the same title, even the gun is the same. Somehow, you can even figure from the picture's name, Kyoko.gif. I'm adding the tag.

Not to mention that the artist for the manga was Kozaki Yusuke, huh?

In any case, use the Japanese name order for Japanese names here.
First-Last, not Last-First (for Japanese names).
