Yang

Yang is a male fox who shape-shifts into a human.
He is evil, but not pure evil, who wants to destroy his nemesis Yin.
Yang has grown up with Yin, until a strange comet has hit Kodama village and Yin & Yang have been cursed by the wolf God Shiranui with electrical powers and 13 brush techniques. Shiranui believes Yang had always evil within him, but was masked by the friendship of Yin. Yang now has more power than Yin and wishes to destroy the land. Yang has all electrical power and 13 brush techniques. He is losing himself, but nothing will get in his way of destroying everything and calling it his own. But, what if he cannot control himself and end up hurting the only one he loves?
