Earth. The not too distant future. A city is miraculously reborn just sixteen years after being completely destroyed by a giant meteor. At the prestigious Graviton High School for Girls, two new students are introduced. A-ko and her ditzy sidekick, C-ko.

A spaceship is lost near the forbidden planet of Inferno II. Some years later, a second ship with a crew of nine gets there and encounters a monster that rapidly makes mince meat of most of them. The sole survivor, Makuro Kitazato, must destroy the monster before it can surprise a third ship that is already en route.
