Drill Sergeant Caricias trains new army recruits, including brothers Gordi and Azulín. Their chaplain instills the troops with a religious doctrine of hatred for the unicorns. Azulín pretends to protect Gordi; hoping to one day become the Chosen One, he aspires to be the best recruit, but grows resentful of the troop's top recruit, Coco. He has also envied his brother since birth: Gordi had come out first, gaining the favor of their mother. When she left their father for another man, Azulín's jealousy grew so vicious that he poisoned his mother's lemonade, killing her.
