There is a ranking system from 1st to 100th. Killers receive requests through the Killer App, earning points based on the difficulty of the request. Once a certain threshold is reached, their rank increases. (If you kill a killer ranked between 1st and 10th and register their badge, you immediately take over that rank.) There are organizations known as King & Kill and the Viper Club.
