Abe no Seimei
In Heian-kyō, nobleman Minamoto no Hiromasa meets court "onmyōji" Abe no Seimei, a mysterious man about whom many rumors have been told. On a dare by some courtiers, Seimei demonstrates his exceptional skills in "onmyōdō" by killing a butterfly without touching it (i.e. casting a spell on a leaf which then flies and cuts through it).
