Literally "the Life giving fist". Fist Means Life, is a belief among martial artists (mainly Ryōzanpaku and the Shinpaku Alliance) where it is believed that martial arts practitioners should not kill an opponent, even if their own lives are at risk.
It has been the main opposition to Satsujinken Yami. Its main representative, as an organization, is the Ryozanpaku and the strongest warrior of this path of martial arts is Hayato Furinji. They believe that life is sacred, that one man cannot take another's life, and so they never fight to kill, always looking to end fights with those involved alive, they always seek to preserve the lives of all.
