Emma attempts to convince Peter Ratri to come with them to the human world. Peter insists that there is no hope for him, and ends up cutting his throat. As he is dying, he remembers how he always looked up to his brother, James Ratri, the previous head of the Ratri clan, but James found out about the farms, and found it unacceptable. He then formulated plans to reverse this, started to call himself William Minerva, and set up many devices and shelters in order to save the children. However, Peter saw this as wrong, and ended up hiring a hitman to kill his brother, Minerva. But after he heard his last words, he regrets his decision and mourns his death. He then slits his throat open, despite Emma's attempts to dissuade him. He seems Emma's suggestions as running from fate. Like the old saying says "A captain goes down with his ship", Ratri decides to die in the building he sees as his fate. With Ratri dead, the Grace Field residents along with the escapees are able to go to the human world at last. Isabella and her crew decide to stay in the demon world to buy them time for them to escape, but Ray tells her "get over it" and come to the human world with them. After a great deal of convincing, she reluctantly agrees, and Emma pulls the lever, which takes the elevator down to a tree-like door, marked with the owl of Minerva. The stick the pen into one of the owl's eye, when the door opens, and they walk into the unknown void. As they disappear, Emma Ray, Norman, and the Lambda escapees reveal that they are staying in the demon world.

Don and Gilda want in on the plan as well, but end up going to the human world in order to help care for the younger children alongside Isabella. Vincent agrees to help care for the mass-production farm children. The doors begin to close, and Phil runs out to hug Emma one last time, promising to come and get them should they take too long. He then waves goodbye to them as the door closes. At last, they made it to the human world. They end up in New York City, where they are helped by the inhabitants there, despite the humans in the demon world's claims to the contrary. The children finally get to wear normal clothes, go to school, and live their lives as regular children. Back in the demon world, everyone else crosses along barren wastelands and mountain ranges, meet children from what appear to be other farms and save them. Emma goes to the Seven Walls and makes a new promise. They finally arrive at the capital after passing a war-ravaged battlefield, and Mujika is able to share her blood with other demons, and gets praised for her efforts. Back in the human world, many years have passed, and all the children have grown, the oldest into adults and the youngest as teenagers. At the outskirts of New York, Phil reunites with Emma for the last time, having succeeded in her mission.

Research elements

 * The city the children reach can be percieved as New York due to the bustling city life, as well as presumably popping next to the Hudson River

Trivia

 * In the manga, Isabella sacrifices herself to give the children time to escape, but in the episode, she and her crew leave with the children to the human world.
 * The human world in their timeline is shown to be really similar, maybe more advanced to the one in ours when it comes to progress. This is debatable, as only New York is seen and not other cities in other countries, if they still exist
