Miko is for priestess in japanese.
Pinkamena is miko and Berriswainer is demon.
Umm...I have been watching Inuyasha lately a few days ago.

Again, you guys can imagine whatever is happening in this scene between these two now...if are you wondering why Pinkamena's skin looks different color: Well, is simple I only use Pinkie's original skin.

Need I say more?
I love the style as well. Though granted, first thought was a Rouroni Kenshin style.
