Knock Yokoyama

The widow of a murdered yakuza boss serves jail time for attacking the man she believes killed her husband. After her release, as she is shadowed by a hitman, she returns to thoughts of revenge.

The warlords overrun the country while the farmers are starving, and forced to become soldiers to keep the wolf from the door. The farmers are recruited in groups of fifteen. In Yaju's village, there are only twelve men, so they press Oto, who looks more like a boy than a girl, to join, disguised as a man.
