Doman Ashiya

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

Appearance
At first, his hair is short and he is wearing a classical monk outfit. 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.

History
A thousand years ago, people lived under the threat of the Impurity King, not being able to defeat it with just Yang power. Ashiya Douman 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 Douman created a monster that grew sharply in Yin power. That was the first impurity ever created.

Douman created the impurities as prototypes for the strongest container of Yin Power, Taiyin.
