In the year 2666, humanity had stumbled across a well of red energy underground, it allowed them to do great things, technology skyrocketed, lifespans went into the hundreds, and humanity had prospered...but it was only temporary.

The power they had uncovered was in fact the power of demons, and it corrupted them, making them no better than demons themselves.

This, along with several other things, inspired Doctor Malak Omar to create a robot that would annihilate humanity, insuring earth would no longer be tainted by demonic power

A-14, or simply 'Angel' was an android created by the doctor mere days before her death.

Mankind was tainted, the doctor was dead

And the machine was active.

Dodging and weaving, Angel killed several soldiers as its arms morphed to cannons, its movements graceful yet efficient as it cut down dozens and dozens of demonized human soldiers.

It shot a bomb from its shoulder cannon, destroying a tank.

"Kill count" It spoke in a mechanized, yet soft voice "6 million"

"Calculating remaining humans...7.5 billion remaining, cleansing will be completed"
