Peter Ratri admired his older brother and former head of the Ratri clan, James, since he was a boy. He always believed that the mission of their clan was to keep its promise, so he could not understand why James acted under the pseudonym of William Minerva to help save the children that were being raised as livestock. Peter chose to sacrifice his brother’s life in order to maintain the order of the world.
When Emma extends her hand to Peter and says, “Let’s be free,” he shows a calm expression, but realizes his fate and ends up taking his own life. The children finally arrive at the gate leading to the human world, where they use Minerva’s pen to open the door and pass through. However, Emma, Norman, Ray, Cislo, Barbara, and Zazie decide to remain behind in the demon’s world in order to save all the children on the farms.
