In a world where large breasts are crucial, Chifusa Manyu, heir of the Manyu family, flees with their secret enlargement techniques. Attacked by her sister Kagefusa, Chifusa discovers her ability to transfer breast size and embarks on a journey with comrade Kaede.

than anything else is ridiculous.
Es ist absurd, dass der Busen Reichtum
darstellt, aber so ist das Prinzip der Welt.

Papá dice tonterías
como que la riqueza es necesaria,
Père prétend des sottises
telles que « les seins font loi ».
Um mundo onde os seios são mais
importantes que tudo é ridículo.
Мир, в котором грудь 
ценнее всего, — безумие.
