In the year 2057, the world has become a corporate-run utopia for the super-rich, and a hellhole for all the rest. Catherine 'Cat' Leblanc is an orphan that is about as far from super-rich as one can be. When the Incursion alarms start blaring and the sky starts raining hungry xenos, it's just another blemish on an already piss-poor afternoon. A cyberpunk magical-girl alien-invasion LitRPG.It’s exactly as wild as it sounds.

Scream out.Awake and pour out the grudge left in you onto me.Then, I shall save you.
