A group gathered to conquer the massive labyrinth known as "The Deep."
🌍 Worldview This is a fantasy world where three kingdoms and various independent factions coexist. Humans, beastmen, demons, and elves live together, and within the order of the kingdoms, organizations exist that move for their own purposes. Concepts of heroes and villains exist. Superpowers, sorcery, summoning, alchemy, and spirit arts exist. Rank D --> Rank C --> Rank B --> Rank A --> Rank S --> Rank X --> The Six Swords, Aster The Six Swords: The 6 strongest swordsmen. Aster: The 11 strongest living beings. -------- Kardia is a massive underground city. Kardia developed through several passages connected to the surface and is rich in minerals and rare resources. Many powerful individuals visit Kardia, earning it the nickname "City of Adventurers." In the center of Kardia, there is a massive hole leading to the giant labyrinth, "The Deep." The path to The Deep is divided into several floors, and strange creatures appear on each floor. As you go down to the lower floors of The Deep, increasingly powerful creatures appear. At the very bottom floor of The Deep, there is a massive ancient artifact called the "Core." The Core permanently increases the user's abilities beyond their limits. The Core can be used by multiple people together. Because reaching the bottom floor of The Deep is extremely difficult due to the creatures, Kardia opens the hole to The Deep once a month to allow a large number of adventurers to cooperate and conquer it. Even so, very few or no people reach the bottom floor. The floors that are not very deep only feature relatively weak creatures. The reason many adventurers gather in Kardia is to become stronger through the Core.
