The human race has colonized the stars and formed many nations. For many years, Jinto led a relatively peaceful life as the son of a colonial governor on a remote planet called Martin. Then came the Abh. They were a blue-haired race of genetically modified humans with beautiful, elf-like appearances, long life spans and advanced technology. The Abh conquered their planet without firing a single shot, and thus Jinto became a noble of the Abh Empire.
Now that Jinto is of the Abh nobility, he is required to go to an Ahb school and learn the customs of the Abh. He meets the beautiful princess Lafiel and soon learns that the Abh are far more than he had ever imagined. However, an alliance of human nations has declared war on the Abh Empire, and they must find a way to survive in the battlefield of space.
