Chifusa and Kaede arrive to the Munemori village, hometown to Chifusa's mother, which is now in ruin. There they reunite with Chifusa's grandmother and Chifusa's aunt, Tsuhuya Munemori, and her baby daughter, Hazuki. Tsuhuya agrees to teach Chifusa how to master the Breast Flow technique. At the same time, Kagefusa and Kokage take Ouka to Edo village, where they have a day of fun and a night of drinking, during which Kagefusa and Ouka discuss the latter's feelings for Muneyuki until they are interrupted by a courier with urgent news. The following day, before the training begins, Chifusa's grandmother tells Chifusa the story of how her mother died, revealing that Chifusa's mother killed herself so the Manyu wouldn't learn how to use the Breast Flow technique for their corrupt ways. Nonetheless, Chifusa vows to learn the Breast Flow technique in order to undo the Manyu's unjust regime.
