The Kaiwan Style is an assassination style that originated in the Ryukyu Kingdom; it is a style that combines the traits of Okinawan karate, traditional Ryukyuan martial arts and Chinese wushu. The Kaiwan Style places high emphasis on partial training, kata training, research of meridians, acupuncture points and qigong. However, the most extreme part of the Kaiwan Style is the hand conditioning users undergo, with users spending most of their time training their hands by stabbing things like sandbags, bamboo poles and even stone; hand conditioning is performed every day without rest, even if the user's arm is broken or shredded. The Kaiwan Style's training does not stop at the hands and feet, with every joint being trained over a ridiculously long period of time; they are at times solid enough to be used as a spear and breaking them instantaneously is nigh-impossible.

Kaiwan Style "Bone Binding"
This Kaiwan Style technique was used by Kuroki Gensai when his entire right hand had been broken wristlocking Kanoh Agito's Dragon Shot. It's nigh-identical to the Niko Style's Bone Binding, and can be inferred that the technique is one of many that originates from the Kaiwan Style.
