Takaai

Takaai was a powerful maho-tsukai whose family name has been destroyed from all records. He was killed in Takaai Grove by an Isawa Tensai of fire after killing the Tensai's daughter. When he was killed, his blood was spread across the grove by the fire, corrupting the grove. Takaai grove has been purified but, it still must be cleansed once a week.
