She is also in Mongolia, but her goal is to find the buried treasure of Yoshitsune Minamoto. The story follows these separate quests as the characters pursue their respective historical riches. It remains unclear whether their efforts will result in the discovery of either Genghis Khan's or Minamoto's hidden wealth.
