1 Prologue

— The beginning

"Sometimes even to live is an act of courage."

Earth is the world where human beings live. Humanity has evolved from using sticks and stones to sophisticated military-grade weapons, but what if?; Would humanity be able to survive if an unknown being from another galaxy attempts to conquer the planet?

Grey is the name given to an unknown intelligent being that resembles a human being and has similar features to a human body but has a distinct eye color. Grey's eyes are a blueish emerald green. 

Year 5500 F.T. humanity almost fell. A chaotic moment that is recorded on the history. 

It was a peaceful day. The sky is so blue, the birds are singing, and you can feel the breeze, but then the sky turns black and a massive mysterious flying object is seen by millions of people on Earth at that moment the sirens' horns could be heard, as well as a sudden blast from various locations. Skyscrapers are crashing, and a lot of people are losing their lives.

A Robotic like creature suddenly appeared it has different types of weapon where some uses gun some are Swords. The height of the Robots are ranging to 18-20ft it was later known as STIGMA (Scientific Techno Intelligent Gateway Machine Android). Grey are using stigma to kill humans; they don't show empathy, even though an innocent child is killed by being stepped on, and they are laughing and having fun by slashing and shredding a human being.

The planet Earth was in a state of complete chaos. The Great War Invasion continued for a long time. Over the past five years, mankind has been losing hope.

But….

When Dr. Rich was able to hack and run a STIGMA that had been stolen from a killed Grey, humanity regained hope and was able to pilot the Stigma and strike back against the Grey once more. 'Soldier Jean' was the Very first human pilot of Stigma. 

It was a great victory for humanity to be able to reclaim a small portion of the world. It takes mankind ten years to reclaim the planet Earth from Grey. After losing their powerful weapon to humans, Grey's Captain was eventually ordered to retire to their home planet; but, before leaving the world, Grey leaves a message that they will return to destroy mankind once more and take the living planet!

The fight to reclaim the home world was won by mankind. The efforts of many people, the blood and sweat, the tears of the families who have lost loved ones, The Great War Invasion became known to mankind on this day!

After the great war invasion, humanity rebuilt its civilization with the help of advanced technology, and the society was given the name Oasis; oasis is made up of four main cities: Pentagon city, hexagon city, octagon city, and Cube city, each of which has a different number of districts.

Following the restoration of society, humanity advances its weapons and creates an elite team to conduct additional research to the Stigma, the group was led by Dr. Rich and it was given the name ERG (Elite Research Group).

Humanity formed elite pilot groups to fight for Grays; each pilot has its own Stigma; the top ten elite pilots were given the name Alpha's.

Many years have passed. The contribution of ERG has resulted in even more improvements to society; humanity now manufactures STIGMA and a wide variety of other weapons and name it Anti Grays.

Humanity also constructs its own elite university, a university for producing elite pilots.
