Extraterrestrial Girls

The time is 2045, and the stage of the story is the Japanese-made space station "Anxin". A boy who was born on the moon, "Tōya" and his childhood friend "Konoha" are rehabilitating on the space station in order to immigrate to the earth. However, they were involved in a collision between the space station and a comet together with the earth's children "Dayang", "Miina" and "Doctor" who traveled to the space for the first time. In a closed space isolated from adults and cut off from the Internet, children who sometimes conflict and sometimes help each other must face various difficulties together such as decompression, EVA (cosmic swimming), and loss of control of micro-machines.
