Years ago, way before I was even born, humanity was reminded that we weren't alone in the universe, and our world was invaded by a race of alien conquerors that called themselves the Ravemites.

It was ghastly. And humanity was soon on the brink of extinction until, we were saved by an Intergalactic Organization that called themselves Starcore Nebula.

Years later, in the middle of this chaotic relationship between mankind and alien, I, Ethan Kaiser — a regular 18 year old kid who had always looked up to these heroes, aspired to be just like them even without awakening any talent, lost my parents in the apocalypse .

Since then, I lost any aspirations I had, any admiration I harbored towards these intergalactic agents. Till one day, I came across a strange system that changed my life forever, and I awakened a talent too.

That Talent's Name was D.E.L.T.A.

And because of it, I was linked to the greatest technological system in the universe, create state of the art weaponry out of thin air? Easy. Hack into the universe's most elite security system? Piece of cake. Being wanted by cosmic beauties across the galaxy? Child's play.

But I didn't go unnoticed, soon enough rival galactic organizations and even alien warlords from all over the universe wanted me gone at any cost, so if they wanted to wage a war against me, bring it on.

I have no desire to become a intergalactic hero, but with this system, I am justice.

So the battle to save earth from these so-called conquerors? it wasn't just the planet's fight anymore, it was mine. They made sure of that the day they let my parents died.
