The Old World Humans

Lore & Background

Despite their defeat, not all knowledge was lost. Certain individuals within the Farm system, such as caregivers who learned the truth, preserved fragments of Old World history in memories and passed them down. This hidden knowledge became the catalyst for rebellion, proving that humanity's spirit survived even when their civilization fell. The Children's journey is essentially a quest to restore what the Old World Humans lost.

In Their Own Story

In the dim light of a forgotten archive, an ancestor from centuries past clutches a journal filled with equations and warnings. Outside, the sky burns with the arrival of shadowy figures who do not bleed like men. She hides the book beneath the floorboards, whispering a promise to future generations that one day they will read this truth and rise again.

Reader's Guide

The Old World Humans are not an active military faction but rather a historical collective whose defeat shapes the current conflict. Their primary goal in retrospect was survival against demonic invasion, which ultimately failed for the majority. Members of this group include the ancestors of the Farm Children and scattered survivors who hid from the Demon regime. While they lack a unified command structure today, their legacy fuels the resistance led by Emma and her friends. In the conflict, they represent the ideal of human freedom that the Demons sought to erase. Understanding their history is crucial for the protagonists to find weapons, technology, and the moral justification needed to overthrow the Farm system.

Did You Know?

• Old World Humans possessed advanced technology that was largely lost during the Demon war.
• The children in the Farms are descendants of these ancestors, but centuries of breeding and separation have resulted in genetic variation, not identicality.
• Some Old World knowledge survived through oral tradition and records, and there is canonical evidence that caregivers like Isabella hid secret books.
• Their defeat led to the creation of the 'Promise'—a dimensional barrier that separated the human and demon worlds.

Origins and Creation

The genesis of this dark fantasy began in late 2013 with an initial draft titled Neverland, which was later renamed to avoid copyright conflicts. Writer Kaiu Shirai submitted a substantial 300-page manuscript to the Weekly Shōnen Jump editorial team, where editor Suguru Sugita recognized its unique potential as an ambitious work blending bright tones with deep suspense. Finding a visual collaborator proved difficult, as several artists rejected the project due to its deviation from standard shōnen tropes or doubts regarding commercial viability. Eventually, Posuka Demizu was selected for her artistic style, which perfectly matched the story's imagery. Their partnership was compared by Sugita to the legendary duo behind Death Note. Before full serialization began in August 2016, the team tested their chemistry with a one-shot titled Poppy's Wish. The positive reception of this short story confirmed that Shirai and Demizu were the ideal creative force to bring this complex world to life.

World-Building and Premise

The narrative unfolds in a fractured reality defined by 'The Promise,' an ancient treaty ending a war between humans and demons by segregating them into separate worlds. While humans live safely, the demon realm operates human breeding farms disguised as idyllic orphanages to raise livestock for consumption. Demons require human flesh to maintain their intelligence and prevent degeneration into mindless beasts. Children are raised under the supervision of a 'Mother' figure, given identifying tattoos, and fed the lie that they will be adopted upon reaching maturity or high intelligence levels. In reality, these children are harvested as food for high-ranking demons. The story centers on Grace Field House in 2045, where eleven-year-old Emma and her friends Norman and Ray discover this horrific truth after witnessing a friend's death at the perimeter gate. This revelation shatters their peaceful existence, forcing them to confront the terrifying reality that they are merely commodities in a supernatural food chain.

Narrative Arc and Conflict

After discovering the dark secret of their existence, Emma, Norman, and Ray formulate a daring escape plan from Grace Field House. However, the operation faces immediate tragedy when Norman is taken away for 'adoption' before he can flee with the group. Emma and Ray make the difficult decision to lead a smaller group of siblings out into the dangerous outside world, leaving younger children behind to ensure their own survival. Once free, they face numerous threats from various demon species but remain determined to liberate their remaining family members and other farm children. Along the way, they form alliances with sympathetic demons like Mujika and Sonju. The conflict escalates as they reunite with Norman and confront powerful antagonists, including the demon queen Legravalima and the human administrator Peter Ratri. Ultimately, Emma's unwavering resolve leads to a victory that secures freedom for all children and re-establishes 'The Promise,' though this triumph comes at the personal cost of her own memories.

Reception and Adaptations

Since its serialization in Weekly Shōnen Jump from 2016 to 2020, the manga has achieved massive global success, circulating over 42 million copies by August 2023. It was honored with the 63rd Shogakukan Manga Award in 2018 and is widely praised for its intricate world-building and character development. The story's popularity spawned multiple adaptations, including a two-season anime produced by CloverWorks and broadcast on Fuji TV. While the first season was critically acclaimed as one of the best anime of the 2010s, the second season faced significant backlash for its rushed pacing and simplification of the source material. Beyond animation, the franchise expanded into a live-action film in December 2020, with an American series currently in development by Amazon Studios. Additionally, a musical stage play adaptation is scheduled to debut in late 2026, further cementing the story's enduring legacy across various media formats.
