About
Twenty years ago, starting with the "Day of Change," Earth transformed into another world.
A "System" appeared before all of humanity, manifesting Jobs, Skills, and Stats, while dungeons and monsters emerged across the globe.
National governments and the UN established the System Agency, organizing society by managing Awakening Gear, Job registration, the dungeon system, and guild licensing.
Eventually, 100 heroic "Rankers" emerged as national-level military assets and the hope of humanity. Rankers are numbered from 1st to 100th. Those ranked 20th or higher are called High Rankers.
While Japan, China, the USA, Europe, and India established stable zones, Southern Africa, Australia, and Antarctica turned into Dark Continents and forbidden zones.

【Terminology】
System
Names, levels, jobs, skills, and stats were visualized. Simultaneously, dungeons, monsters, experience points, rewards, and quests appeared, drastically changing the world. Nations integrated the System into their social structures, and modern society has been reorganized to persist.
System Agency
The System Agency is a supra-national management organization established by national governments and the UN to respond to the altered world.
Adventurer Rank System
Adventurer ranks are classified from E to S. Among S-ranks, those whose achievements are highly evaluated are called Rankers.
Ranker
Rankers are the 100 strongest official combatants of humanity, recognized for their achievements and combat capabilities by nations, guilds, and international organizations, existing in a hierarchy from 1st to 100th.
Cancer
Cancer is a general term for high-level ability users not registered in the official Ranker system, who refuse registration for various reasons. Many are involved in criminal organizations, illegal Awakening Gear, forbidden research, or smuggling, and are designated for surveillance. However, not all Cancers are criminals or enemies of humanity; it is a term for "unregistered high-level ability users."
Named Monster
Named Monsters are rare monsters that have acquired high intelligence and self-awareness, gaining individual names. Some lead species or swarms as kings, chiefs, or rulers, and are viewed as extremely dangerous by guilds and the System Agency due to their intelligence and leadership. Most are S-rank, with extremely rare cases being SS-rank. However, not all are enemies of humanity; friendly individuals do exist.

Intro
One day, Earth transformed into another world.
Unknown continents floated in the sky, labyrinths opened their maws on the ocean floor, and dungeons were born in forests and beneath cities.
Before the eyes of the people,
"The System"
appeared, and the concepts of Jobs and Stats became reality.
Currently, Earth is beginning to regain stability.
Asia (including Japan), America, Europe, and India have established stable zones, creating a society where magic and science coexist.
However, Southern Africa, Australia, and the Antarctic continent—the Abyss—remain beyond humanity's reach.
In the midst of such a turbulent era, you have awakened.
First, it would be wise to head to the Adventurer Guild...
