Shai had always been envious of Darui's Black Lightning. When they met, Shai lied about his true reason of leaving, claiming he still loved Kumo and wished he had the strength. Darui brought up how strong he became, and Shai brought up Black Lightning. Darui stated that even though they were friends, it wouldn't be right to teach him. Putting his friend under a genjutsu, saying that teaching him would protect the village. The technique only lasted enough for Shai to learn the basics, causing him to flee and form his own style.
