Manyu Scroll (Manyuu Hiken-chou) - Season 1, Episode 07: Boobie Kid

Chifusa and Kaede stop at a village so Chifusa can get a massage to ease the pain caused by her heavy tits. The masseus, a girl named Momoha, tells them of 'The Boobie Kid' a local thief that steal's rich women's tits and allegedly gives them to the poor. Suspecting that this Boobie Kid might be a Manyu who knows how to master the Chichinagare technique, Chifusa takes a job as a bodyguard for a local big-breasted woman who will likely be the next target in order to catch the Boobie Kid. At the same time, the big-breasted landlady also employs another girl called Ouka as a bodyguard and immediately Chifusa becomes suspicious of Ouka because of her unusually good swordsmanship. That night, the Boobie Kid strikes but is chased away and caught by Chifusa. The Boobie Kid is later revealed to be Momoha, the masseus, and that she is a member of the Munamori family and that she knows a technique similar to the Chichinagare that Chifusa cannot use. At that point, Ouka arrives and reveals herself to be a Manyu assassin; she proceeds to attack Chifusa and nearly kills her but fails due to Momoha's interruption. While fleeing, Momoha is fatally wounded and as she lays dying gives Chifusa her tits so she can use their essence to master both the Manyu and Munamori techniques before bidding her farewell and wishing her good luck on her mission.
