Yang
Master Kodokuna Yang [ 1 ] was a martial art teacher, the creator of Airjitzu and later, a spirit trapped in the Temple of Airjitzu . Yang taught Airjitzu to his students , but he secretly wanted to live forever so his work wouldn't be forgotten. Using the Yin Blade , he tried to become immortal, but its powers backfired and he became a ghost , cursing him along with his temple and students. Years later, the ninja later traveled to the Temple of Airjitzu to claim the Scroll of Airjitzu , but they were tormented by Yang. During their escape, Cole was turned into a ghost. . Sometime later, as Nadakhan rebuilt his home realm , the Temple of Airjitzu was lifted into the sky and cleansed with water, forcing him and his students to flee. After Jay made his final wish, recent events were undone, but due to an anomaly, the temple remained floating in the sky. . On the Day of the Departed , Yang deceived Cole into retrieving the Yin Blade and temporarily revived the ninja's old enemies, pitting them against the ninja as a distraction while resurrecting himself through the Rift of Return . As the ninja fought their adversaries, Yang opened the Rift while Cole fought his students. Cole would eventually confront Yang and destroy the Yin Blade , allowing Yang's students to cross through the Rift. Yang opened up about his arrogant desire to live forever, allowing him and Cole to make amends.
