Murasame is the living sword spirit, rumored to have sway over anything regardless of shape or form. It is said that whoever possess Murasame will meet a tragic end. The spirit can transform into a crow and can communicate human language. Murasame sometimes sits on Shino's arm and likes to pick and eat food droppings, which Shino has scolded Murasame for.

When their village was wiped out five years ago, only Shino Inuzuka, Sosuke Inukawa, and the girl Hamaji, who was raised as if she were their sister, survived. And both men inexplicably have the same peony-shaped birthmark. Genpachi Inukai and Kobungo Inuta were raised hundreds of miles away as foster brothers, but they too share the same birthmark. When they went north as part of the army three years ago, they went to confront demons and came back forever transformed. Now the Imperial Church has come for Shino and Sosuke and they must find eight mystical gems and their owners or face a fate worse than death at the hands of the Church.<br><br>
