The year is 2122. It is almost impossible to stay outside because of the sudden climate change; the rain is full of acid, the Sun is burning people's skin, the resources are running low. The control mechanisms of the states have almost collapsed, people attack each other and even kill each other to survive. Alone in this chaos, Asteria takes shelter in the building known as the Seed Bank to survive, but it doesn't take long to learn the hard way that this is actually a Space Research Center. Asteria, who has made herself accepted by the team here by her old connections and profession, embarks on a difficult journey.
