Azuya

Azuya [梓缠; あずや, also known as Azuyakami] is the god of misfortune, evil and discord in Kiren. Born from the improper mating ritual conducted by Inōtō and Iyane, he is considered an 'outcast god' or utakami who is not deserving of worship or appeasement by humans. His sole intent and purpose is to spread malice, conflict and misery throughout the world. The legend of the birth of Azuya (and to a lesser extent his brother Hiyakami) is widely considered to be a warning against ignoring tradition or ritual.
In Kiren tradition, cremation is partially required in order to make sure that souls are properly purified and thereby safeguarded against possible abduction by Azuya. If Azuya is able to take control of a 'lost soul' that has not undergone purification after death, he will often twist it into an evil spirit which seeks to wreak havoc upon humans.
