The Rhythmic Fist (律動拳, Ritsudō ken) is a form of taijutsu developed by Ji, the purpose of which is to afflict external damage while avoiding damage with flowing and unpredictable dance-like movements. The style itself is a strange blend of "hard" and "soft" martial arts, at times intercepting an opponent's attack with the user's own and at others directing the opponent's force in a different direction in order to create openings.
