On a night with a sky full of shining stars, an earthquake shook the entire world. But this was no ordinary earthquake—it created a massive abyss, as large as a city. This event affected every corner of the Earth.
The abyss was pitch black, and no one could see what lay inside it. However, strange sounds echoed from its depths. Yet, humans are naturally curious. In response, they formed exploration organizations, training individuals through intense programs before sending teams to investigate. But most of these teams never returned. The few who did were poisoned by unknown toxins—90% of them perished. The survivors, however, gained extraordinary physical abilities, making them faster, stronger, and more resilient.
Thanks to these rare survivors, humanity discovered that the abyss contained valuable resources and creatures unlike anything seen before. Thus, they named this mysterious chasm "The Abyss."
100 Years Later
After a century of exploration, humans managed to uncover three levels within the Abyss. Each level looked almost identical to the others, with no significant differences. However, to move between levels, explorers had to defeat the Floor Boss. Upon victory, a small cave would open, allowing access to the next or previous level. Interestingly, these Floor Bosses were also nearly identical, and once defeated, they would reappear after 24 hours.
One day, an unexpected earthquake struck again. It was an ominous sign. But this time, no new abyss appeared. Instead, something astonishing happened—the Abyss transformed.
The once pitch-black chasm became a breathtaking forest, filled with plants of various colors and types. The sight was mesmerizing, leaving people speechless. As they gazed in awe, whispers spread among them:
"Beautiful... So beautiful..."
The Rise of Two Organizations
This transformation led to the formation of two major organizations:
1. The Explorers – Led by Arisu, this organization consisted of scientists and researchers dedicated to studying the Abyss, its resources, and its creatures. However, they lacked fighters.
2. The Guardians – Led by Archie, this organization was composed of powerful warriors ranked based on their abilities and combat experience.
The ranking system was as follows:
Rank E: Regular people with no experience in the Abyss, but trained in basic survival and combat.
Rank D: Soldiers with battlefield experience but no knowledge of the Abyss.
Rank C: Fighters with moderate skills and minor experience inside the Abyss.
Rank B: Survivors of the Abyss who developed physical abilities twice as strong as an ordinary athlete.
Rank A: Survivors with physical abilities four times stronger than an athlete.
Rank S: Known as the Superhumans, these were the strongest survivors, They possess unique abilities that set them apart from other Ranks . Only three individuals held this rank, making them the elite of the Guardians.
And so, humanity stood at the edge of a new era, facing the mysteries of the Abyss like never before…
