Muneyuki and Ouka lead a batallion of four Manyu assassins to capture Chifusa and Kaede. The two, along with Tsuhuya Munemori, face off agaisnt the assassins, defeating one of them before being outmatched. However, they are saved by the timely arrival of Kagefusa and Kokage, who join in on the fight. When the fight begins to get too rough, Chifusa's grandmother tells her to take Hazuki away with her to protect the last child of the Munemori bloodline; though initially hesitant, Chifusa and Kaede agree and flee with Hazuki. However, they are cornered by Ouka, who wishes to settle her old score with Chifusa as well as defeat her to gain status among the Manyu. Ouka initially has the upper hand in the fight, but halfway through it, Chifusa manages to unlock the Breast Flow by remembering how she had earlier attained a mother's heart... by breastfeeding Hazuki, which allowed her to have a motherly bond with one of her kin. Chifusa uses the Breast Flow technique agaisnt Ouka and manages to make her breasts grow, which weakens her long enough for her and Kaede to flee with Hazuki. Later on, Chifusa and Kaede find Kagefusa, Kokage, Tsuhuya and Chifusa's grandmother, who defeated the assassins and fled as well. After returning Hazuki to Tsuhuya and reassuring Kagefusa that she will return her breasts, Chifusa and Kaede continue their journey.
