It tells the story of a young father who must come to terms with the fact that his newborn son is severely mentally disabled.

Soon after day-dreaming about his trip and a brawl with a few local delinquents from the region, Bird receives a call from the doctor of the hospital regarding his newborn child, urging him to talk in person.

Bird is troubled by the revelation, and regrets having to inform the relatives of his wife about the facts concerning the state of the child, who is not expected to survive for long.

Bird struggles with this fact, and desires the child to die as soon as possible so as to not have the responsibility for the so-called "monster baby" to ruin his life and his prospects for travelling by himself to the African Continent.

However, haunted by the ordeal of his dying child, Bird is unable to achieve an erection at the mention of the word "pregnancy" and "womb" uttered by Himiko, and ends up resorting to the practice of BDSM.

Back at his cram school job, he meets one of his friendly students who wishes to claim that the vomit incident the earlier day was caused by food poisoning, and not hangover, in order for Bird have better chances of not being fired.
