Inori no Kuni no Riviere

The stage is set for two girls in a land where prayers have become curses. In a small island nation, there is a mysterious town where people's prayers are answered by a mysterious force. I, Makmilia, assist the enigmatic Riviere in our shop, where we deal with the dangerous items borne of those prayers. We've got a fate-changing perfume, a talking vase, and a bag containing strange creatures, just to name a few. Yes, indeed, the deeds of the marvelous duo, Makmilia and Riviere, will overshadow even the Ashen Witch Elaina!
