Icy Fang (A Kakashi Story)

Teams' Asuma, Gai, Kurenai and Kakashi are sent out to the borders on a very specific mission. Find out the threat behind the border attacks, rescue any survivors, and kill whoever's in charge. There's just one more detail; a woman from Kakashi's past is joining them, and Kakashi's thoughts are plagued as he tries to figure out his emotions without driving himself crazy.
