Chifusa Manyuu ( , Ma'ny Chifusa) is the protagonist of the Many Hiken-ch manga and anime series. She is the successor of the Manyuu clan and an expert samurai. Despite the fact that she was meant to continue the tradition of the Manyuu, she deserts her family because of her hatred of the unfair system with which her family governs (which consists of judging women's worth based on the size of their breasts) and steals the Scroll of Secrets, which contains techniques on how to enlarge breasts. She is also the only person capable of a technique known as Breast Flow (Chichi-nagare), which allows her to control the form of breasts and thus allows her to enlarge or reduce breasts, whether they be her own or others... Chifusa makes it her ultimate goal to master the Chichi-Nagare so she can ensure all women in Japan a decent-sized bust. A key part of her personality is that she disdains how people are treated in society with regards to who has breasts and who does not, and what that can afford you in the Manyuu Universe.
