A:
Set in Japan during an unspecific year of the Edo period, Ogami Itto, disgraced former executioner, or Kogi Kaishakunin, to the shogun, wanders the countryside, pushing a baby cart with his 3-year-old son Daigoro inside. A banner hangs off his back. "Ogami: Suiouryo technique" (Child and expertise for rent)([son] [for hire] [arm|skill] [for hire] [to serve] [Suiouryo] [ogami itto]), it says. His services are asked for in a most unexpected way, when an insane woman seizes Daigoro from the cart and proceeds to try to breastfeed the boy. Daigoro at first hesitates, but after stern look from his father, he proceeds to suckle the crazy woman's breast. The woman's mother then apologizes for her daughter's behavior and tries to give Itto money, but the stoic ronin refuses, saying his son was hungry anyway.As he walks in the rain, he remembers another rainy day several months earlier when his wife, Asami, was slain by three ninjas, ostensibly in revenge for Itto's execution of a boy daimyo, but it was really part of a complicated plot by the shogun's inspector Bizen and the "Shadow" Yagyu Clan to frame Itto for treason and take over the executioner's post.Now a wandering assassin for hire, Itto takes a job from a Chamberlain, to kill a rival and his gang of henchmen, who pose a threat to the chamberlain's lord. The chamberlain plans to test Itto, but a quick slash behind his back with his Dotanuki sword dispatches the chamberlain's two men. The targets are in a remote mountain village that is home to hot-spring spa pools.As Itto pushes the baby cart, and Daigoro observes scenes of nature, such as a mother dog suckling one puppy, and two children singing a song and bouncing a ball, Itto thinks back again to the time just after his wife was killed. He gave Daigoro a choice between a toy ball or the sword. If the child chose the ball, Itto would put him to death send him to be with his mother a better place in his opinion. But the curious child...
