故事发生于某所高中的文艺部内。很轻易就陷入妄想之中的小野寺和纱（河野日和配音）、总是不经意之间做出惊人发言的菅原新菜（安济知佳配音）、恋爱经历为零，异常单纯的文学少女须藤百百子（麻仓桃配音）、想要创作属于自己的小说的本乡一叶（黑泽朋世配音）和性格非常古板，对性的话题避之而不及的社长曾根崎莉香（上坂堇配音），隶属于文艺部的是这五名性格迥异的部员。 一天，大家正在讨论“死前想要做的事情”这一话题，平日里默默无闻的新菜突然暴言“想要体会一下性爱”，这句突如其来的发言让整个文艺部都陷入了混乱之中，少女们虽然对这句话的反映各异，但她们的心都被次撩动了。。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.
