The story differs from that of the original novels or anime and is presented as an additional "Spice and Wolf" world. Ami Koshimizu provides the voice of Holo in the game. The game was released on the same day in limited and regular editions; the limited edition was sold at a higher price, but comes with a life-sized poster of Holo, among other things.
