|Manga Debut||Act 210|
Geezer is a kindly and friendly old man who wanders from place to place and resides within the fallen villages when he chooses to stay in one place for a while. When Kenshin falls into a deep depression after he believed that he had failed to protect Kamiya Kaoru from being killed, Geezer gently persuades Kenshin (partly through the use of hakubaikō perfume, which has the same scent as Kenshin's deceased wife Yukishiro Tomoe) to find his purpose to stand again rather than listen to his friends telling him to avenge Kaoru, who mean well but lack the insight to realize what Kenshin's inner conflict is.
He is later revealed to be the father of Tomoe and Enishi. He is aware that Tomoe has died and also of Kenshin's relationship to her. He is last seen with the broken Enishi in the fallen village in Tokyo; father and son remark that their company seems familiar, though Enishi fails to recognize the identity of the old man while Geezer's knowledge of the young man's relation to him is left more ambiguous.
Geezer appears to have a keen understanding of other people's natures. He correctly surmises Kenshin's inner conflict and its outcome, and later predicts that Enishi will also some day find a new purpose in his life.
