Earth's Martial God

I come from Earth! Blind in both eyes from the start, how can I turn things around? I awakened a god's talent, only to be struck by a god's curse. But when I break the curse, stand tall among the stars, and rule over the Solar System, I discover that the stars beyond Earth's surface are fake. Humanity is trapped inside a painting... Gods are born above all others. They do not save the world, but regard all living things as mere straw dogs, looking down on humanity as if we were ants. If that's what it means to be a god, then I'll slaughter every last one of them! I am Earth's Martial God, and I am the godslayer who hunts gods!
