With a deadly asteroid hurtling towards Earth, sexy human Dragonauts in tight uniforms and their curvaceous dragon companions come together to create a formidable fighting force with all the right moves. Caught in the middle of this race against time are Jin – a heartbroken young flyboy, and
Toa – a voluptuous mystery woman with an amazing set of intergalactic battle skills. Jin’s down about the fate of his doomed planet, but Toa is quick to grab him by the seat of his pants and lift his sagging spirits. If these star-crossed space cadets can unlock the secrets of their mysterious connection and convince the Dragonauts to join the action, there may yet be hope for planet Earth!
Twenty years prior to the story’s beginning, an asteroid headed for Earth destroys Pluto. Due to Pluto’s destruction, the asteroid, which is dubbed Thanatos, becomes temporarily stagnant. Now, in order to avoid Earth’s impending destruction, the International Solarsystem Development Agency (ISDA) works on the “D-Project”, and creates the “Dragonaut” after finding a dragon egg under the ocean. This weapon’s primary purpose is to destroy the asteroid when the time comes. However, they soon find out that the asteroid is not their only threat, as powerful dragon-like creatures, which are bent on destruction, appear on Earth.
After witnessing a murder by one of the creatures, Jin Kamishina, a lonely 18-year-old boy who lost his family in a shuttle accident two years ago, gets involved in the mysteries of the dragons and becomes the chosen pilot of the Dragonaut. Helping him on his journey is Toa, a mysterious girl who saves him from falling to his death after the creature attacks him. As they get deeper into the mysteries of the dragons, they encounter new friends and enemies, and also begin to develop a closer relationship.
Several years ago, Jin Kamishina’s family was killed in what appeared to have been a space shuttle accident. A few years later he is suddenly attacked by a strange monster, but is saved by a strange girl named Toa who possesses superhuman strength and can transform into a dragon. Jin finds out that the accident was not due to an error by his father, the pilot, but rather as a result of a collision with an object from outer space – the asteroid Thanatos, the source of destructive dragons appearing on Earth. As they make new friends and enemies, Jin and Toa now find themselves becoming increasingly entangled in the mysteries of the ISDA – a shadowy organization working to protect humanity – and the dragons themselves…
