Sousei no Onmyouji - Twin Star Exorcists Wikia

Doman Ashiya (蘆屋 道満?) is an arch rival of Abe no Seimei and an enemy of Kuzunoha who was first perceived as the Spirit Guardian of Benio Adashino.


At first, Doman has short hair that slightly resembles Rokuro Enmado's hair. In time, however, his hair grows longer and he is seen with a beard. His eyes turn black from being exposed to the miasma of Magano for too long. He has a distinctive sign on his left cheek.

He is wearing a classical monk outfit.


A thousand years ago, people lived under the threat of the Impurity King, not being able to defeat it with just Yang power. Doman is the one who studied the humans who had been mutated due to the power of the Impurity King. He removed their Yang power and, as a result, he got a new type of energy, the Yin power. Something went wrong during the experiment and Doman created a monster that grew sharply in Yin power and it was the first impurity ever created.

Doman created the impurities as prototypes for the strongest container of Yin Power, Great Yin.

Not much is known to Doman, but he seemed to be confident of himself, even somewhat narcissistic, as he attribute Benio's beauty to his very low degree of consanguinity.
