avenge Kaoru, who mean well but lack the insight to realize what Kenshin's inner conflict is. He is then revealed to be the father of Yukishiro Tomoe and Enishi. He is aware that Tomoe has died and that Kenshin was her husband. Geezer is last seen with the broken Enishi in the Fallen Village; father and son remark that each other looks familiar, though it is left unknown whether either knows their connection. Watsuki based Geezer off of an empty milk can who is a character in "Now go, Robot!," a story by Makoto Ōishi. The motif of the entire plotline involving Kenshin in the Fallen Village is based on that same story, with it also taking influence from the comic Silver Surfer by Moebius. Watsuki used no design model for Geezer. He was created simply based on the attributes; homeless, "an unusual personality," and not easily showing his true thoughts. Afterwards, Watsuki noticed that Geezer was very similar to Grandpa Bob in Bøy by Haruto Umezawa. Tsukayama Yutarō is a young boy and Isurugi Raijūta's "apprentice." Yutarō's father, , is a former samurai who became rich by selling swords to Europeans. Yutarō feels that his father's actions degrade him and wants to show him how a true samurai lives by the sword. The Tsukayama family was deceived by Isurugi Raijūta, who faked a robbery so the Tsukayama family would pay him to teach Yutarō how to use swords. Yutarō trains at Kamiya dojo a little and becomes Myōjin Yahiko's rival, the two gaining a mutual desire to become better than the other. When Raijūta initiates a failed sneak attack on Kenshin's group, he accidentally slices Yutarō's right arm so that the nerves are severed, therefore making Yutarō unable to hold a sword with that hand. Yuzaemon takes Yutarō to Germany to get medical treatment. Before he leaves, however, Yahiko confronts him, scorns his sulking, and tells him that he can overcome his sorrow by working to be better than he imagined Raijuta to be. Yutaro responds that he will never stop practicing swordsmanship and his left arm is still enough to become great. At the end of the series, Yutarō's name is listed as one of the acting instructors of the Kamiya Kasshin-ryū dojo, along with Yahiko. In the anime Yutarō's father, a well-known swordsman, is dead. Yutarō, who had inherited a lot of money after his parents died,
