Manyuu Hikenchou

During the Taiheimeji Era under the Tokugawa shogunate, the Manyuu Clan serves as a group of warriors loyal to the government. In this time, large breasts are of immense social and economic value, determining a person's status and humanity. The Manyuu Clan is responsible for nurturing those destined to have large breasts, using techniques recorded in a secret scroll. Chifusa is chosen to inherit the clan's role, but she steals the scroll and flees, seeking to challenge the harsh societal norms the clan has helped establish.
