Q:I am a movie director and I just received the following movie plot. Could you help me answer this question? If not, let me know by writing "Not answerable". Plot title: Seven Samurai Movie plot: Bandits approach a mountain village, but their chief decides to spare it until after the harvest because they had raided it before. The plan is overheard by a farmer. Three farmers ask Gisaku, the village elder and miller, for advice. He declares they should hire samurai to defend the village. Since they have no money, Gisaku tells them to find hungry samurai. After little success, the group watch Kambei, an aging but experienced ronin, rescue a young boy who had been taken hostage by a thief. A young samurai named Katsushiro asks to become Kambei's disciple. The villagers then ask for help, and after initial reluctance, Kambei agrees. He recruits old friend Shichiroji and, with Katsushiro's assistance, three other samurai: the friendly, wily Gorobei; the good-willed Heihachi; and Kyuzo, a taciturn master swordsman whom Katsushiro regards with awe. Although inexperienced, Katsushiro is selected because time is short. Kikuchiyo, a man who carries a family scroll that he claims makes him a samurai, follows the group despite attempts to drive him away. On arrival, the samurai find the villagers cowering in their homes, refusing to greet them. Feeling insulted by such a cold reception, Kikuchiyo rings the village alarm bell, prompting the villagers to come out of hiding. The samurai are both pleased and amused by this, and accept him as a comrade-in-arms. Slowly the samurai and farmers begin to trust each other as they train together. Katsushiro forms a relationship with Shino, a farmer's daughter, who had been masquerading as a boy for protection from the supposedly lustful samurai. However, the six samurai are angered when Kikuchiyo brings them armor and weapons, which the villagers most likely acquired by killing injured or dying samurai. Kikuchiyo retorts that samurai are responsible for battles, raids, taxation and forced labor that devastate the villagers' lives. By so doing, he reveals his origin as an orphaned farmer's son. The samurais' anger turns to shame. Three bandit scouts are spotted. Two... My question: Who is revealed as an orphaned farmer's son?

Kikuchiyo
