It is a few days after Kuka and Artemis met. They are good friends, and get along together well. But suddenly, Kuka's father Ku comes through their lands. He sees Kuka and is angry. He never wanted Kuka to have anything in life.
So when Artemis comes to see what is going on, she sees Kuka and his father. She knows he is an awful horse and is sort of scared.
Seeing Artemis makes Ku furious. He doesn't like it at all, so he attacks!
