Abe no Seimei
Kato is incredibly proficient in a variety of eastern magic, most notably the art of Onmyōdō, possessing abilities that rival the Tsuchimikado Clan, descendants of Abe no Seimei. He extensively employs black shikigami to do his bidding, and he can also summon goho doji. He is also known to use kodoku (worm toxins) to control and manipulate his victims.
