时间点为TV版两年后的暑假。海人成为了高中三年生，其他人亦踏出了自己的道路。有天，去了海人家中游玩的哲郎发现了一卷磁带，而当中记录的正是两年前的暑假、拍摄电影前所拍摄的试拍。。荒野难驯，只能奋力搏生存。。Bipedalism, or 'two-footed walking', is the story of a painter who grew up in an orphanage and only years later learns the circumstances of his father's disappearance and death. Childhood memories bring the main character back to the past: he buys a house in the suburbs that used to belong to his family. In the basement, he finds his father's archives and scientific research documents on the hybridization of human race with related biological species. Studying the archive material, he unexpectedly finds evidence of efforts to renew the experiments on the remaining hybrid population. The painter then becomes a researcher, and consequently a victim. The basic idea of his father's research was to change, control and influence the process of human evolution - initially connected with eugenics theories of the period before World War II, and now being placed in a context of modern 'biotechnological' expectations by his former colleagues. The main character tries to recreate and realize his father's heritage, who was forced to cooperate with state terror organizations, using the results of his secret research. In a tragic manner, this information turns into the main character's reality, at first forcing him to reappraise his father's values and later driving him to madness.
