Detonator Orgun

In the distant future, humanity has already settled the Moon and Mars and ventured beyond the Solar System. The protagonist, a young man named Tomoru, dreams of something more than the job at a prestigious company that his brother has promised him. His peers do not share his aspirations, but Tomoru feels that he has a special destiny. At the same time we meet Orgun, an alien warrior who betrayed his own race to protect the Earth. Having given his life for humanity, he creates a duplicate of himself that can only function by merging with Tomoru.

The Evolders, Orgun's kin, begin attacking the Earth, and the fate of the planet ends up in the hands of Tomoru and the enigmatic Orgun. No one knows the alien's true intentions, and his protection could bring unpredictable consequences for humanity. Tomoru must unravel the mystery of Orgun and save the Earth from the looming threat, overcoming the inner and outer obstacles on his path.
