The Road to Earth

Eighty thousand years ago: The Lloyd cannibal tribe invaded Earth and knocked its axis out of alignment. Humanity on the surface regressed by 50,000 years overnight. A few Earthlings escaped underground and survived by sheer luck.

Fifty thousand years ago: To protect Earth, fourteen planets in the Milky Way inhabited by humanoid races joined forces to select warriors from among humanity on the surface and form a mysterious army: the Kunlun Mountain Divine Soldiers. Meanwhile, the Earthlings who had taken refuge underground evolved into the three-eyed Subterraneans. They were ordered to build a lunar space station to guard Earth's orbit.

Today, a great plague has divided humanity. Some flee Earth, while others are "saved" by alien intelligence... Think all is calm? No. An even greater war is only just beginning.

The descendants of those chosen warriors bear seven-star birthmarks and are returning to the world...

Fighting alongside them is a girl with mixed genes and alien blood. In gratitude for the care Earth has given her, she swears to defend it to the death.
