Biped walking, or "bipedal walking", is the story of an artist who grew up in an orphanage and learned about his father's disappearance and death several years later. The memory of childhood brings the protagonist back to the past: he bought a house in the suburbs that used to belong to his family. In the basement, he found his father's archives and scientific research documents on the hybridization between human and related biological species. While studying the archival materials, he unexpectedly found the evidence of conducting experiments again on the remaining hybrid population. The painter then became a researcher and thus a victim. The basic idea of his father's research is to change, control and influence the process of human evolution - initially linked with the eugenics theory before World War II, and now placed in the background of modern "biotechnology" expectations by his former colleagues. The protagonist tried to use his secret research results to rebuild and realize his father's legacy, and he was forced to cooperate with the national terrorist organization. In a tragic way, these messages became the reality of the protagonist. At first, they forced him to re-evaluate his father's values, and then drove him crazy.
