Chifusa and Kaede rest for the night in an abandoned shack after Chifusa comes down with a fever. While they are resting, Kaede mentions that Chifusa had only come down with a fever like that eight years prior (in an incident she does not recall which ended with Kaede being assigned as Chifusa's attendant). Chifusa begins to recall what happened what day while at the same time, in Muneyuki's house, Ouka does the same. It turns out that Chifusa had accidentally used the Breast Flow technique before during a duel she had with Ouka eight years prior and had accidentally stolen her breasts. After recovering, Kaede and Chifusa continue their journey, concluding that Chifusa has yet another set of breasts to return after she masters the Breast Flow technique. (Source: Wikipedia)
