Ansatsuken
Ansatsuken (暗殺拳, literally "assassination fist") is a Japanese neologism used frequently in fictional works to describe any martial art style or fighting technique that has been developed with the purpose of killing an opponent. The term satsujinken (殺人拳, literally "murderer sword") is used interchangeably as well.
Examples in fiction
Hokuto Shinken from the Fist of the North Star franchise, which is described as an "assassination art passed down from one master to a single successor" (一子相伝の暗殺拳, isshisōden no ansatsuken). The term ansatsuken has also been applied as well to other fighting styles in the series, particularly Nanto Seiken, Gento Kōken and Hokuto Ryūken (see list of fighting styles in Fist of the North Star).
Tenshū, Suichū, and Chishū, the three sons of Zekū in Ironfist Chinmi, are collectively known as the "Three Brothers of the Assassination Fist" (暗殺拳の三兄弟, Ansatsuken no San Kyōdai), as each of them are proficient in their own assassination styles: Hangetsuken (半月拳, "Half-Moon Fist"), Sentōken (旋刀拳, "Whirling Blade Fist"), and Ryūsōken (龍爪拳, "Dragon Fang Fist") respectively.
