A middle-school girl named Mikako Nagamine is drafted to the UN Space Army in a war against a group of aliens called the Tarsians, named after the Martian region (Tharsis) where they were first encountered. As a Special Agent, Mikako pilots a giant bipedal robot or mecha as part of a fighting squadron attached to the spacecraft carrier Lysithea.

When the Lysithea leaves Earth to search for the Tarsians with Mikako on board, Mikako's boyfriend Noboru Terao remains behind. The couple continues to communicate across interplanetary, and eventually interstellar space via the e-mail facilities on their mobile phones.

As the Lysithea travels deeper into space, the e-mails take increasingly longer to reach Noboru on Earth, and the time-lag of their correspondence eventually spans years.
