Black Ice

Yuzuru was abadoned at birth in a forest - in Demon world. She was found by one of the Great Shinobi - Ice Master Shinta. He trained her hard to become his succesor - but due to her lack of Spirit Energy her rival and friend Touya became his succesor before he died. Now - thanks to Genkai - she's fighting with Yusuke and his team to win the dark Tournament.
