In a reign ruled by the Tokugawa shogunate, breasts mean everything. Those who have breasts are guaranteed wealth and popularity. The women who lack them are not considered "human". Members of the ruling Manyu Clan help raise future big breasted women. Written on a secret scroll possessed by the clan, there are said to be various techniques on how to grow big and beautiful breasts. Chifusa Manyu is to be successor of the clan. However, she takes the secret scroll and runs away with it, hoping to fight against the cruel world that the Manyu Clan has created.
