In the story, Kaoru is the teacher from a kendo school from Tokyo called Kamiya Kasshin-Ryū. The school starts to lose all its students when an imposter starts killing a large number of people and claims to be the "Hitokiri Battōsai from the Kamiya Kasshin-Ryū". Kaoru encounters him but before being killed by him she is saved by the real Hitokiri Battōsai, now a wanderer, Himura Kenshin, to whom she offers to stay in her dojo as she notes Kenshin is a gentle person instead of a hitokiri.
