Masamori has sworn his life to guarding a sacred shrine, a solitary samurai shaped by Bushido and haunted by past failure. Once a loyal retainer to a daimyo, he carries the weight of lost honor and a lord he could not protect. The shrine and its monks are his refuge, yet since a mysterious maiden arrived, the air stirs with subtle signs, animals gather fearlessly, faint lights shimmer, and a presence he cannot name tugs at the edges of his heart.
