Far distant future, on a planet that might have been called “earth?, there
was a war between samrais who mechanized their bodies. After the long war,
people have retrieved a modest peace.
In those days, people in Kanna Village are suffering from the Nobuseri, who
are the ruined samurais. After the war ended, they lost their purpose to fight,
and they’ve been robbing the village of their crops and women. Because they
don’t have any way to fight against them, they have to obey Nobureri’s order.
One year, before harvest season, Gisaku, a head of the village, propose that
they will hire samrais to protect them from Nobuseri. Riki, who is a young boy
full of energy, Kirara and Komachi, twin priestesses, go to a town to look for
samurais to help them.
