Sho Ten Kao or "Many Legendary Faces" is a powerful martial art taught only in the Krosian Archipelago.
Origins of this technique were designed back in the time of the Thirteen Sentnels as their leader Train D. Oversoul fought with martial arts as his Devil fruit possessed limited offensive capabilitites. Originaly this technique had no name and was fast paced and similar to Hyuuga style. However it was passed down to Oversouls son Mach who began to add more power and moves to the technique. He used it in battle coupled with his speed devil fruit which made him more dangerous. In the end however the technique remained unnofficially named until Mach's daughter Maka learned the technique. She incorperated moves and styles that reflected her ancestors battle types and added moves she learned from fighters she encountered making and naming the most primitive form of this art Sho Ten Kao because of all the powerful warriors who were used in the creation of the art. She passed this technique on down to her son Whisp, and it was his soul means of offense during his life until he learned Haki. He refined the technique and added more moves to it throughout his life. It was what kept him alive in Impel Down. Whisp's Son eventully learned the technique during his travels through time when he encountered his father. He took the technique and refined it to it's ultimate point by traveling time and infusing it with the moves and techniques of every fighter in history, but then the technique was said to have vanished. However it did not. During the final battle of Grey Fafnir, powerful former warriors of Krosia were temporarily reincarnated. Those who knew the technique likened it to Roukushiki, however passed on it's secrets as a modular art to Balkan D. Shane who used his Devil Fruit to transmute instruction on the art into a stone wall. His son Ivor eventually created the Sho Ten Kao Dojo for warrirors intent on protecting the Krosian Archipelago though he and Shane never learned the technique. Though not it's ultimate form it retains is refined modular style and users of this technique are encouraged to modify their learinings to best suit their style of battle. No two styles of Sho Ten Kao are alike in this aspect.
