Ashiya Doman

蘆屋道満
Ashiya Dōman was an onmyoji rival to Abe Seimei and would keep challenging him to magic duels and endlessly lose to him. So one day Dōman seduced Seimei's wife in exchange for his spell book. He revealed to Seimei that he made love to his wife and used a spell to slit Seimei's throat. To add insult to injury, Dōman married Seimei's ex wife. A sorcerer from China who knew Abe Seimei traveled to Japan and resurrected Seimei. Dōman received word that Seimei was seen alive. To prove it to himself, Dōman confronted Seimei which happened to be true. Seimei used the same spell Dōman used to murder him to kill Dōman and his traitor ex wife for revenge.
