Kido, referred to by his initial name Katsura Kogorō, was among the historical personalities present in the manga and anime "Rurouni Kenshin" by Nobuhiro Watsuki, as well as its OVA adaptation . While still portrayed as a ruthless radical leader of the Chōshū clan, he serves as a benevolent mentor of sorts to the young Kenshin Himura, who worked under him as the "Hitokiri Battōsai." He nonetheless regrets having Kenshin do the dirty work for him after Kenshin's affair with Tomoe Yukishiro (in "Tsuiokuhen", he actively encouraged Tomoe to stand by Kenshin to serve as a calming influence), which ultimately boiled over into a clash with her ties as a shogunate agent and her will to live life anew in the new era of modern Meiji Japan. He is voiced by Tomokazu Seki.
