User blog:CherryLilith/Mysterious characters?

Hi, yesterday I looked on Himaruya's blog and found out that in new entry there is a picture of two girls in Gakuen Hetalia uniforms.

Who are they? New nations or some characters from some of his other works? Or just some random girls created just to show uniforms?

(b.t.w. One of them kinda looks like my OC Czech :)
