10 biggest things that no longer exist in the Chainsaw Man universe

In the dark and twisted world of Chainsaw Man, the Chainsaw Devil wields a fearsome power: the ability to erase entire concepts, events, and entities from existence. As revealed in a tense conversation between Makima and Kishibe in chapter 84, this power extends to erasing memories, ensuring that humanity remains oblivious to these lost elements.

Makima explains that any Devil consumed by the Chainsaw Devil has its name—and therefore its entire being—erased from existence. This has led to a universe starkly different from our own, where significant aspects of history and human experience, such as World War II, AIDS, and nuclear weapons, have been wiped out.

This article explores the ten biggest things that no longer exist in the Chainsaw Man universe, highlighting the dramatic impact of their absence.

Soviet Union, ears, Arlonone syndrome, and others are among the biggest things that no longer exist in the Chainsaw Man universe

1. Soviet Union

In the Chainsaw Man world, there is no Soviet Union as the Chainsaw Devil, a significant power in world history, rooted it out. As for cooler heads to prevail, however, the Cold War never happened, and global politics and history have been transformed.

There are few or no events like the arms race and the Space Race, resulting in different technological and scientific developments. Consequently, many nations within the collective of the Soviet Union have distinct histories and have taken different paths in their development. The lack of this superpower hold is why the new kind of world is not as tense as the one major portion of the 20th century could be in the Chainsaw Man Universe.

2. Nuclear bombs

The Chainsaw Devil has blown up nuclear bombs, which represent the final indications of destruction. In this world, there are no such things as the Atomic bombings of Hiroshima and Nagasaki and nuclear weapons and arms race in the Cold War period.

First of all, since there are no nuclear weapons at all, there cannot be such a thing as the MAD system, which gives the fundamental base for different political and military systems all over the world. The power described here need not be total and is changeable, which may lead to new ways of preventing and managing conflict. This affects the development of the international relations system and changes power relations around the world.

3. World War II (Including Nazis and The Holocaust)

These entailed the elimination of World War II with the Nazis and the Holocaust by the Chainsaw Devil. This means the world has never witnessed one of the worst conflicts. The events such as the formation of Nazi Germany, the Holocaust, and the perpetration which was committed against Jews for which the Nazi leaders were tried in Nuremberg never existed.

One concerns itself with the creation of NATO and the United Nations, along with other post-war multilateral organizations, all of which change frameworks for the organization of collective action. This erasure leads to a significantly altered socio-political landscape that empowers nations that mimic the dominant discourses in many ways.

4. AIDS

AIDS, a disease with profound impacts on global health and society, no longer exists due to the Chainsaw Devil. Without AIDS, the significant public health crisis and the associated stigma and discrimination are absent. Medical advancements driven by the need to combat HIV/AIDS are also missing, potentially slowing progress in treating other viral diseases.

Social movements and changes in sexual health education sparked by the AIDS epidemic are different, leading to an altered understanding of public health and human sexuality. The absence of this disease fundamentally changes the world’s response to public health issues.

5. The light of a particular star that would break children's minds

In the Chainsaw Man universe, the Chainsaw Devil has erased a star whose light could psychologically break children's minds. This celestial phenomenon is no longer a threat, removing a unique danger from the cosmos. Any scientific research, folklore, or cultural impacts surrounding this star and its harmful light are eradicated.

The absence of such a dangerous element ensures the mental health and safety of children, preventing a unique cosmic danger that our reality cannot fathom. Though no concrete information is found for this, it will make the readers search for it and question whether they are forgetting too, which aligns with the manga's lore.

6. Four conclusions other than death at the end of living beings' lifespans

The Chainsaw Devil has erased four alternative conclusions to living beings’ lifespans, leaving only death as the outcome in the Chainsaw Man universe. These alternative conclusions could have included transcendence, eternal stasis, absorption into a collective consciousness, or transformation into a different life form.

Their absence simplifies the concept of mortality, impacting philosophical, religious, and cultural beliefs. Societies now focus solely on death as the inevitable end, shaping their rituals, perspectives, and understanding of life and existence. This profound change affects how humanity perceives and deals with the end of life.

7. Ears

The Chainsaw Devil's eradication of ears creates a profound shift in physiology and communication in the Chainsaw Man Universe. As Special Divisions 5 and 6 battle the Chainsaw Devil, the carnage includes Pochita consuming the Ear Devil. Suddenly, Public Safety observes through their cameras that everyone's ears are vanishing.

This forces beings to adapt to a world without hearing, leading to the development of alternative communication methods, such as enhanced visual and tactile signaling systems. Sign language becomes the norm, and sound-based technologies and art forms, like music, cease to exist. This change reshapes societies, cultures, and daily life, creating a new sensory experience in the Chainsaw Man Universe.

8. Sixth sense all humans used to have

Humans once possessed a sixth sense, which is nowhere to be found in the Chainsaw Man universe. This sense could have provided abilities such as heightened intuition, precognition, or perception of supernatural phenomena. Its removal significantly alters human behavior, culture, and survival.

The absence of this sense affects cultural, scientific, and spiritual practices built around it, leading to a profound shift in human experience and interaction with the world.

9. Mt. Hio Eruption

The Mt. Hio eruption is a catastrophic volcanic event that ceases to exist in the Chainsaw Man Universe. Without this eruption, landscapes, ecosystems, and climates remain unchanged. Communities that would have been devastated by the eruption are spared, leading to different historical and cultural developments in those regions.

Any myths, legends, or scientific studies related to the eruption are also erased, impacting knowledge and lore surrounding volcanic activity and natural disasters. This absence significantly alters the geological and cultural history of the world, preserving regions that would have otherwise been transformed by this natural disaster.

10. Arlonone syndrome

Arlonone Syndrome, a disease that once plagued the Chainsaw Man universe, has been eradicated by the Chainsaw Devil from the memories. This syndrome, which could have caused a major health crisis, affecting millions and altering societal structures, no longer exists. The medical community, freed from combating this disease, focuses on other health issues.

The social, economic, and cultural impacts of dealing with and overcoming Arlonone Syndrome are absent, leading to a world without the challenges and triumphs associated with fighting this disease. Arnolone Syndrome is a fictional creation by mangaka Tatsuki Fujimoto, designed to confuse readers and align with the manga's lore.

Final thoughts

The Chainsaw Man universe presents a chilling vision of a world where the Chainsaw Devil's power has erased crucial elements of history, culture, and human experience. As revealed in a tense conversation between Makima and Kishibe in chapter 84, the Chainsaw Devil's ability to consume and erase Devils extends to their names and entire existence.

Makima elaborates on being one of the Four Horsemen of the Apocalypse, explaining that even she cannot remember these things, though she remembers the fight between their Devils and the Chainsaw Man.

These erasures not only reshape the physical world but also wipe away memories, leaving humanity unaware of what has been lost. The revelations underscore the terrifying implications of such power and the delicate balance between existence and oblivion. This explains a deeper understanding of the transformative and often horrifying influence the Chainsaw Devil exerts on the world.
