Guardian of the Milky Way

To seize the galaxy's last source of power, invaders from another world spread a virus across Earth. In a single night, zombies overran the land and flames of war rose everywhere. Earth revived once more, releasing evolutionary factors that caused humanity to evolve. But the virus interfered with these factors, and every species on Earth began evolving at a rapid pace. Meanwhile, the first-generation evolutionaries, the legendary gods and demons, joined the battle. To claim true victory, we journey through the boundless sea of stars. For peace, and for the sake of my destiny, I will fight the Underworld King and protect this sanctuary. "I will protect what I hold dear, until the day I can no longer fight!"
