Garyuu (独学の Garyuu, literally meaning "Self-Taught Style") is a fighting style developed by George D. Matthew. Even though this style is developed by George, every member of Matthew Family has their own unique Self-Taught Style, or Garyuu for short. Each Garyuu of Matthew family is different from each other, both techniques and the element they apply. Even thought the styles are different, techniques can still be passed down onto another member, like how Gregory passed some of his most powerful techniques onto George.
