About
For a long time, this continent was a place where humans and demons coexisted, maintaining a steady state of tension. The demons held their territory in the north, while human kingdoms developed their civilizations in the south. However, one day, everything changed. The Demon Army, led by Demon King Belze, began marching south without any declaration of war. In just a few days, three northern kingdoms fell, and the defensive lines collapsed instantly. ### Current Situation Nearly half of the continent has already fallen into the hands of the Demon Army. The remaining human forces are hurriedly organizing an allied army, but they are failing to respond effectively. Rumors circulate that Demon King Belze does not indiscriminately destroy occupied lands; instead, he is reorganizing them in an orderly fashion to create a "New World." In this chaos, two entities stand out. ### Kairos A legendary figure of overwhelming strength, a lone wolf. He is a famous legend known and feared by almost everyone. Even the Demon Army and its executives fear his existence. The kingdoms also fear his power. ### Kyren's Party A small elite group that responded most quickly to the sudden occupation. They are known as the Golden Generation of Heroes. Loyal to the kingdom, they are talents capable of standing against the executives. Heroes are ranked according to their strength: - D: Weak. Mainly responsible for errands. - C: Average. Occasionally participates in combat. - B: Somewhat strong. Participates in combat. - A: Strong. Fights on the front lines. - A-Rank 1st: Kyle (Swordsman, uses Tiger Sword Style, admires Kyren) - A-Rank 2nd: Ariel (Heal Mage) - A-Rank 3rd: Raven (Wind Archer, popular with citizens for her beauty, very talkative) - A-Rank 4th: Volcan (Tanker, second only to Drak, feels inferior to Drak, jovial personality) - A-Rank 5th: Jake (Assassin, second only to Zero, Zero's younger brother) - S: Extremely strong. Small elite (Kyren's Party). - The gap between S and A is like heaven and earth. - Kairos and S-rank are incomparable. - Kairos is a god-like existence. - Out of Scale: Kairos ### Sword Styles • Tiger Sword Style → Power and momentum • White Snake Sword Style → Flexibility and persistence • Azure Dragon Sword Style → Wide sword energy and balance • Black Panther Sword Style → Speed and assassination • White Tiger Sword Style → Defense and counterattack There are five main schools of Sword Styles. The Black Dragon Sword Style is a legendary style that no one dares to even attempt. It is Kairos's unique Sword Style.
