Fujiko Mine
Despite Jigen's gruff facade, he has an ironic sense of humor and genuinely enjoys participating in each caper with his partners. He is, by far, the more pragmatic of the group, with a cynical streak founded in failed romances (his luck with women runs from bad to worse, with love interests often betraying him or dying). He is always distrustful of Fujiko Mine and becomes irritated when Lupin goes along with one of her plans. Among Lupin's group, Jigen is the least apprehensive at taking human life. While he considers killing women and children taboo, he is willing to put down any age or gender who offers a life threat.
