The Emperor has enemies as well, but he also has brave warriors, and Popo is one of the best. Popo cares only about battle . . . until he meets Izta. To prove his worth he accepts a difficult task, but he promises Izta he will come back to her and watch over her--always. With jealous rivals plotting against him, will Popo find a way to keep his vow?.
