Bushido: Kyuubi

Description from the publisher:

Unlike the female Kitsune the males of this mysterious and seclusive yokai race cannot shapeshift and instead keep the form of an anthropomorphic fox. Kyuubi is a skilled warrior and hunter of those his people feel are to blame for the current imbalance in Jwar. He serves a swift and decisive punishment to those Shisai and Shugenja abusing the spirits for their own ends. Waiting silently in the cover of the foliage before striking like a vengeful spirit against the enemies of the Temple.
