A few months ago, Shinobu Kocho helps train Tanjiro during his rehabilitation period, and, while she initially does not understand his drive to protect his Demon sister, she does grow to care for him. Though she trained Tanjiro, Zenitsu, and Inosuke, she seems to be the closest (or, is at least the least irritated) with Tanjiro because unlike Zenitsu and Inosuke, he took his training seriously from the start. Tanjiro's love interest is Kanao Tsuyuri, Shinobu's Tsuguko.
