Disrupt the Sixth Harmony was a Mastery 5 martial earth kiho which remained in secrecy by the Kuni family. Created in the 12th century as result of centuries of research into the sixth element and the anatomy of creatures of the Shadowlands. The Shadowlands Taint flowed through a minion of the Shadowlands, so disrupting this flow was lethal. This kiho had no effect on spirits from other realms, including oni, because such entities were simply too in tune with the Taint to possibly disrupt.
