Healing Fist (癒し拳, Iyashi-ken, VIZ: Trauma Fist) is Chowa's signature fighting style, it was birthed from his training under Takewa Sozo and his own beliefs in the Kyumeiken. The style itself doesn't draw from any distinct existing style and is more or less a general application of Iryotaijutsu (医療体術, Iryōtaijutsu). The principle of Healing Fist is to fight without fear of taking anothers life which Chowa as both a doctor and a follower of the Kyumeiken has sworn never to do. Through the infusing of Igaku Chakra into the users body in combat not only does on boost their own innate healing ability which strengthing ones own body, they also gain the ability to heal what they strike. To most this may seem useless as why would you want to heal your opponent in the middle of a fight, but in reality which the physical injuries inflicted are healed all pain, trauma and suffering remains leaving the target in agony but physically unharmed.
Some have said that it is the "wrong or inappropriate" way to use Iryōjutsu.
