About

Killer Ranking: Ranks from 1st to 100th; others are unranked. In the lower ranks, the ranking rises by 1 step for every 10 points collected. Killing Check: The act of assassinating or eliminating a target. Killer App: A dedicated application created by the King & Kill group that all killers are required to use. It controls all killer activities, including ranking management, requests, orders, and location tracking. Killer Points: Points are both cash and experience for ranking up. TOP 10 Rule: Absolute rules unrelated to the point system apply to the top-tier rankers from 1st to 10th. (The Killer Badge must be tagged in the KILLER App.) From the 10th rank onwards, tagging a Killer Badge immediately usurps that killer's ranking. Exchange Rate: 1 Killer Point equals 10 million KRW. Transactions range from menial labor (catching mosquitoes for 0.001 points, picking up cigarette butts for 0.0001 points) to high-profile assassinations (hundreds to tens of thousands of points). Killing Intent (Sal-gi): A special energy possessed by killers. Ordinary civilians, and even doctors who have worked in the killer world for a long time, cannot detect it. One can detect an enemy's killing intent to avoid attacks or emit it to influence or even cause mental damage to an opponent. The killing intent of ordinary killers is usually red, but some killers emit unique colors. Members of the Viper Club mainly exhibit venomous intent, while King & Kill members exhibit fighting spirit (Tu-gi). Fighting Spirit mixed with Killing Intent: The killing intent released when killers awaken. In KING & KILL, it appears white, while others release different unique colors, accompanied by the Hanja character for 'Extinguish' (滅). Madness mixed with Killing Intent: An extremely rare killing intent that can even kill the spirit of a strong killer. It appears alongside red killing intent and the Hanja character for 'Madness' (狂). Killer: A profession that carries out assassination requests and various other tasks for money. With the commercialization of the KILLER App, they can operate legally. They may join killer groups or engage in Killing Check duels to usurp rankings, and the strong are often targets for Killing Checks. Each possesses unique killer weapons and killing intent. Killer Badge: A physical badge symbolizing a ranker (1st–100th). Tagging it to one's smartphone (app) grants points. Giant Organizations: Representative groups include KING & KILL and the Viper Club, though several hidden masters belong to neither. Crown Construction: A construction company founded by KING & KILL. The representative is Chairman Wang. It is suspected to be the hideout for KING & KILL. KING & KILL: A major killer organization alongside the Viper Club. Crown Construction is affiliated with this organization. Killers here are primarily named after chess pieces (e.g., Hey Knight, Pawn 6, etc.). They are called by their chess piece names rather than their real names. The hierarchy is Pawn < Knight < Bishop < Rook < Queen < King < Chairman, though skill level does not strictly follow the piece value. The Chairman is called Chairman Wang. Except for Pawns, there is only one of each chess piece, while there are eight Pawns (Pawn 1 to Pawn 8). Relationship with Viper Club: They appear to be on bad terms. It is a group of highly skilled individuals, and it seems the closer one is to the King, the higher their rank. Viper Club: A major killer organization alongside KING & KILL. Members all have the names of venomous snakes and possess characteristics and attire matching those snakes. The hierarchy is Headhunter < Member < Captain = Executive < Elder = Founder. The founder also holds the rank of Elder. Relationship with KING & KILL: They appear to be on bad terms.
