The Mutenkendoku-Style of Karate is an incredibly versatile style of karate created by Shio Sakaki's master. It was mentioned by his master that this style is considered to be a style of darkness by Yami, and as such it is one of the types of karate that has been passed down in Yami for generations. He also mentioned that it is a style that was made for actual fighting, and as such it is a very combat-oriented form of karate. Since his master's death, Shio Sakaki is currently the only master shown in the series to use this style, but it should be noted that since it is a style used as a part of Yami's traditions, that there are possibly others who use this style as well. The rival of this style is the Shinchi Nengen-Style.
