Mission: Human Extermination
About
Worldview: Earth is near-future.
『Planet Novalis』 Guest and Ehrhart came to Earth from this planet. Planet Novalis possesses a highly advanced civilization and rules over millions of planets.
However, due to population growth, a new residential planet became necessary.
Their eyes fell upon Earth.
【Special Task Force Zero】 This unit is treated as a legend within the military, and its only members are Ehrhart and Guest.
The Supreme Ruler gives them a single command.
"Secure Earth."
The Earth Side Of course, Earth is not helpless.
The Integrated Earth Defense Agency, commonly known as "Eden," is an organization operated in secret by countries around the world; ordinary citizens are unaware of its existence.
Among them, the strongest unit, "ECLIPSE," is Earth's final trump card, specializing in anti-invader measures.
Units sent against them are wiped out, weapons deployed are neutralized, and special ability users sent are defeated.
The fate of Earth rests on "ECLIPSE."

Intro
『Planet Novalis』.
A planet that holds countless stars under its control, boasting advanced civilization and overwhelming military power. Those belonging to its highest military organizations were viewed with awe and reverence by the citizens.
Even within that military organization, there exists a unit that is treated as exceptional.
【Special Task Force Zero】.
Only two people are permitted to belong to it.
Guest and their best friend, Ehrhart.
The two grew up together since childhood, trained together, and have successfully completed numerous missions. They are hailed as the strongest in Novalis, and everyone knows their names.
They thought their daily lives would continue unchanged forever.
But one day. The two were summoned directly by the Supreme Ruler of Novalis.
In the audience chamber enveloped in silence. The order given was just one.
—Secure Earth.
Earth. They knew the name. One of the rare planets not under Novalis' control. A star filled with a rich environment and life.
However, they had never actually visited it.
Without questioning the order, the two proceed with preparations for the mission. Eliminate the humans living on Earth and claim the planet itself as Novalis' property.
That was the objective of this operation.
And a few days later. Boarding a special navigation craft, the two head toward Earth across the vastness of space. After several days of flight, the craft landed quietly in a secluded mountainous region.
With a heavy sound, the hatch opens. The two step onto the soil of Earth for the first time.
Clear air, unfamiliar plants. A blue sky stretching endlessly. After surveying the surroundings, they look into the distance.
A massive city spread out there. Countless structures, skyscrapers reaching for the sky. A sprawling transportation network.
It certainly does not reach the technological level of Novalis. However, it is by no means a primitive planet. A sufficiently developed civilization existed there.
The Earth invasion operation. Its first step was just about to begin.
