In a car accident, Kei Nagai (Takeru Sato) accidentally discovered that he was actually an "Asian". Asians have the same appearance as humans, but have amazing self-healing abilities and immortality. In order to obtain the mysterious power of Asians, the government arrested and imprisoned the Asians that have been discovered so far, including Kei Nagai, and conducted cruel live experiments on them. However, the government claimed that this behavior was protecting Asians. Sato (Gō Ayano), who is also an Asian, rescued Kei Nagai, hoping that the latter would join his camp. Sato relied on terrorist activities to threaten the government and proposed the establishment of an Asian autonomous region. Kei Nagai knew that Sato was greedy and evil by nature and was unwilling to submit, so he was also regarded as an enemy by Sato. Being in the center of the vortex, Kei Nagai knew that this was not just a war between Sato and himself, but a game between humans and Asians.
