Enter a world whose past involved a large-scale war between samurai and mechanized samurai bandits, known as Nobuseri. The samurai fought a losing battle and retreated, and the war ended with an uneasy peace. Now the Nobuseri plague farming village periodically taking all their food and supplies and, sometimes, their women and children. The peasants of one village, Kanna, decide to seek samurai to fight off the Nobuseri on their behalf. Three villagers, Kirara the water priestess, Komachi her sister, and Rikichi, a farmer, set off to the city to find samurai who are willing to work for rice.
