Genius of a Unique Lineage

I want to be someone who kills invaders

I want to kill invaders and live a happy daily life in a special world.
Can’t I just ask for that?
Why? Why can’t I do that?
People say chasing two different rabbits will make you miss both, but…
just don’t miss them.

(Here is a better description of the series based on the first chapter of the manhwa. I cobbled it together using parts of the intro of the manhwa’s first chapter from Asura Scans and filling in other bits.)
Someone told me about the world before I was born. So… the world before the Earth Blackholes appeared was a normal world.
This story is about an abnormal world. Where unknown life forms emerged from these blackholes that communicates with another world. These invaders massacred many humans, and when the world started turning into a living hell, a special species of human showed up. They had extraordinary abilities and helped to resolve the situation. But people came to fear the special species and separated them from normal humans. Some went to the government. Others conspired with international companies. And the rest made their own organization and hid themselves with magic.
Its been twenty years since the blackholes first appeared. The special species are still there, hiding their true identities, living amongst normal people.
