Prologue

First, there was darkness, and then the magnificent Sun appeared. This massive sphere of hydrogen and helium holds itself together through the force of gravity. It emits a brilliant light, illuminating the planets that revolve around it in their own unique orbits.

Some planets receive different amounts of sunlight based on their distance from the sun and position in their orbit. The third planet from the sun, located approximately 93 million miles away, has one moon and stands out due to its distinct color compared to the rest.

This planet, Earth, is the only confirmed one known to harbor living organisms, all thanks to the production of Telsma. Telsma is an invisible form of energy generated by Earth and everything within it, providing the necessary energy for the planet to sustain itself and support life.

The creatures who identify themselves as humans are unable to perceive Telsma, unlike animals who possess a sixth sense enabling them to feel its presence all around.

In this vibrant land, numerous kingdoms flourished, each boasting breathtaking landscapes, majestic mountains stretching as far as the eye could see, and exquisite wooden ships gracefully navigating the vast seas. Life seemed idyllic for the inhabitants, despite occasional conflicts with neighboring nations over limited resources.

This world is Earth, a place of breathtaking beauty and captivating mysteries. On a rare occurrence during the first day of a blue moon, a phenomenon takes place when numerous minute dust or smoke particles fill the air. These particles are typically much smaller than the wavelengths of visible light.

The moonlight reflects back, giving the moon a bluish hue. On that day, scorpion-like creatures emerged, their bodies transparent like ice. Although their organs remained unseen, tiny sparkling spheres adorned their entire bodies. These living organisms survived by absorbing Telsma energy from the earth.

Nobody knows what caused the emergence of these organisms or how they came to exist, but one thing is certain - their stings are extremely dangerous. These organisms produce a unique poison that exclusively affects humans, which is precisely why they exclusively prey on humans, earning them the distinctive name "Scorpios."

When someone is stung by a Scorpio, the Scorpio mysteriously vanishes like smoke, and the skin of the person stung begins to turn purple, a signal that the poison is swiftly spreading through their body. This creates a peculiar new being - these creatures resemble humans, but there's something distinctively unusual about them.

Their body undergoes drastic changes when affected by the poison, causing excruciating pain that is life-threatening. Their ears elongate, nails grow in length, and their once bright eyes turn bloodshot red. Their nails and fangs turn poisonous, making a single bite or scratch capable of transforming others into the same state. However, unlike the Scorpio, they are unable to absorb Telsma.

Because of this, they began hunting humans in order to reproduce, their sole purpose being to replace humans with their own kind. These creatures are known as full breeds, and their existence poses a life-threatening threat. To counteract this danger, numerous churches and military forces from around the world joined forces to create an organization called the Special Services Unit, also known as the S.S.U.

At their disposal are cutting-edge tools of our modern age. They wear shoes equipped with air-absorbing technology, where the release of compressed air produces a powerful explosive sound, propelling the wearer higher than any jumping creature. Additionally, they wield weapons capable of effortlessly slicing through or piercing even the toughest of rocks. Their attire resembles that of Roman soldiers, providing both functionality and style.

The S.S.U's sole purpose is to safeguard the human race against threats, whether it be dangerous individuals or entities. However, amidst their efforts, there were peculiar individuals who, despite being injected with the Scorpio poison, did not undergo mutation like the rest. The only noticeable distinction about them was the presence of a skull symbol in one of their eye pupils.

They were known as "Tags" - individuals who had survived the poison of the Scorpio and possessed mysterious powers.
