Knuckle Master (拳闘士, Kentōshi lit. Fist Fighter) is a class within The World that specializes in unarmed, hand-to-hand combat, equipping gloves and knuckles as weapons. Though they are not present in SIGN or the Games, the class was added to the game sometime during the 4-year gap between the Twilight Incident and Legend of the Twilight. The only known player of this class was Ouka, an elite player whose fighting style has earned her the nickname "The Divine Fist". It is later replaced by the Tribal Grappler class in The World R:2.
