In this world, there are humans who can live forever. Even if they are fatally injured, they will recover quickly in a short time. People call them "Asians". Nagai Kei (voiced by Mamoru Miyano) is an ordinary high school student. One day, a car accident exposed his identity as an Asian, and he was immediately wanted by the relevant government departments at a high price. With the help of his former friend Kaito (voiced by Yoshimasa Hosoya), Nagai Kei embarked on an endless escape. On the way, Nagai Kei met Sato (voiced by Yoshitada Otsuka), who is also an Asian. Sato wanted to include Nagai Kei in the Asian group he secretly formed, but the sensitive Nagai Kei discovered Sato's hidden true face and purpose. Asians have been persecuted and cruelly studied by the government, so Sato attempted to regain the rights of Asians through a series of terrorist attacks. Nagai Kei joined Tosaki (voiced by Takahiro Sakurai) of the Asian Management Committee and fought against the powerful Sato under his leadership. Between Asians and humans, a war full of smoke and blood is about to begin.
