One day, he is visited by aliens, who demand that he raise their baby for a year... or else the world is history. The baby is apparently human, and is raised the way humans are: through breast-feeding. Kyuuichi's sex is not a problem for the aliens: they give him a simple device that switches his body to a woman's with the mere touch of a button.

That means going to a store to buy a breast pump, visiting a maternity hospital to get a massage to release Kyuuichi's stored-up milk, and giving the baby a bath together. Kyuuichi, as a biology student, is fascinated by the whole thing from an academic perspective.
