On November 23, 1957, the whole world witnessed the Federal Republic of Zirnitra's monumental achievement of sending the first live animal—a dog—to outer space. Since then, the space race between the confederacy and its competitor, the United Kingdom of Arnack, has intensified; the two countries hope to one day send humans to the cosmos above. As a dog's biology is inherently different from a human's anatomy, there is no way to perfectly identify the risks involving space travel and its effects on an individual's body without actually sending someone for observation. However, Zirnitra's government has a potential solution: to experiment on vampires, whose biological similarity to humans is too significant to ignore. Despite being forcibly taken from her home in the mountains, vampire Irina Luminesk shows no resistance and is even willing to train as a test subject. Lev Leps, a former top candidate to become the first human cosmonaut, is designated to accompany Irina and act as her guide. Through their time together, Irina and Lev begin to develop a mutual love for outer space, bringing them closer together.

The movie retelling of the final half of the Turn A Gundam series.

It is the Correct Century, two millennia after a devastating conflict which left the world broken. Earth is now mostly uninhabitable, and thus a remnant of humanity has resided on the Moon while the Earth and its few survivors recover. For years, the Moonrace, the people of the Moon, have continued to check if Earth is fit for resettlement. A boy named Loran Cehack and two others are sent down to Earth for a reconnaissance mission. Loran ends up spending a year on the planet working for the Heim Family, aristocrats living in a Victorian-like society. This family, like others of similar wealthy status, celebrates one's coming of age with a ceremony involving a giant stone statue known as the White Doll. To Loran's surprise, the Moonrace suddenly touches down on Earth with the intent of taking it by force. During the attack, the White Doll is broken apart, revealing a mobile suit called the Turn A Gundam inside. With Loran in its cockpit, the Turn A causes a standoff between the forces of Earth and Moon. The young pilot, along with the people of both sides, must keep the peace and avoid another all-out, catastrophic war.
