Dragonaut: The Resonance - S01

Twenty years before the story begins, an asteroid on a collision course with Earth destroys Pluto. Because of Pluto's destruction, the asteroid, named Thanatos, is temporarily stopped. Now, to prevent Earth's coming destruction, the International Solarsystem Development Agency (ISDA) works on the "D-Project" and creates the "Dragonaut" after finding a dragon egg under the ocean. The weapon's main purpose is to destroy the asteroid when the time comes. But they soon learn the asteroid is not their only threat, as powerful dragon-like creatures 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 earlier, gets caught up 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 go deeper into the mysteries of the dragons, they meet new friends and enemies, and also begin to grow closer.
