How would modern technology change demon killing?

Key insights

  • Modern technology could replace traditional weapons like Nichirin swords with firearms for demon slayers.
  • AI-controlled robots could improve demon detection and make fighting demons more efficient and strategic.
  • Incorporating technology into demon slaying could raise ethical dilemmas and change the nature of the series.



Demon Slayer takes place in a world where people are helpless against powerful and malevolent demons. People can only rely on well-trained demon slayers. Wielding Nichirin swords and special breathing techniques, these hunters face their demonic opponents with unparalleled strength, skill, and determination. The series emphasizes the eternal battle between good and evil, where bravery, skill and strategy are equated with triumph in a time without modern technology.

With Demon Slayer Set in modern times, traditional techniques and tools are giving way to a high level of technological progress. If so, it would bring significant changes to how hunters enter battles and what skills and tactics demons use to escape them. The addition of firearms, advanced detection systems and AI-controlled robots would bring a new dynamic to combat and could make for faster and more efficient demon hunting.

Demon Slayers will not be limited to melee combat as the technology replaces Nichirin swords with firearms, just as Genya uses one, but a much more advanced firearm as using a double-barreled shotgun is more of a hindrance given the long reload time. When making firearms, gunpowder can be made from scarlet iron sand for deadly bullets that could kill demons. Such specially forged bullets, now with the same properties as the Nichirin blades, will give hunters the ability to attack from long distances and not always come into close contact with demons.


If this happened, the Demon Slayer Corps would become much more effective and the range of attacks and tactics used would increase dramatically. Demon Slayers could operate from a safer distance and cover a larger area without necessarily having to risk being injured in close combat. With new long-range capabilities, the Corps would be able to launch coordinated, large-scale attacks on demon lairs, redefining the way it detects and disrupts at the strategic level.

A new frontier in detecting and combating demons

How robotics could change the dynamics of combat.

AI robots with advanced sensors and tracking technologies could play an indispensable role in detecting demons in the modern world Demon Slayer. With their motion sensors, thermal imaging, and energy detection capabilities, these robots will be able to scan for demonic energy signatures, making it difficult for the demons to actually hide or be in plain sight. Demon combat robots could continually patrol cities and the countryside to form a defensive line. However, we see some kind of robot with Yoriichi's doll, which was used as a training dummy for demon slayers. Improving the same technology and programming these robots to hunt demons would be a start.

The problem is that where there is great power, there is also great risk with AI-controlled robots. Such robots lack the complex decision-making processes that would make them human, and can therefore attack friendly demons like Lady Tamayo, who mean no harm and have renounced their violent nature. There is an ethical problem with this technology that could easily target any demon and wreak havoc in the nuanced moral world of demon killing.


Muzan's Tactics and Demon Survival Strategy

How modern detection could force demons to evolve

If modern technology could bring man closer to his ability to detect and neutralize demons, then the progenitor of demons, Muzan Kibutsuji, would be forced to adopt such advances in technology and evolve. He could no longer hide so easily and “fit in” among people. He and his followers would be under constant threat from AI and other methods of scanning equipment. This could be an intriguing turn of events, forcing Muzan to change his behavior and attempt to use new powers in the hopes of somehow nullifying these modern technologies or sabotaging AI systems.


The ever-present possibility of disclosure via multi-tiered information networks could force Muzan's strategy to become more calculated: rather than simply expanding and dominating, he could well focus on weakening human technology or infiltrating systems to disrupt demon-hunting operations. Such changes would reduce the resistance to demon-slaying to a game of intelligence and technology that is constantly changing, with one side trying to outsmart the other.

While they could potentially dramatically reduce human risks with AI-based robots, serious ethical challenges could result. Without the empathy and discretion of human demon slayers, robots would be unable to make important distinctions between non-threatening demons that have since renounced violent lives. In the case of Lady Tamayo and her followers – peaceful and seeking an end to Muzan's tyranny – the AI's inability to show discretion would mean that even “good” demons could become victims.


This lack of judgment could lead to moral conflict within the Demon Slayer Corps, driving characters like Tanjiro, who is based on compassion and understanding, to have a million questions about the ethics of such new tools. The AI-powered demon hunt would bring the series' moral questions to the forefront: the debate over who deserves redemption and whether technology could truly understand the nature of good and evil in this supernatural world.

Modern technology would redefine Tanjiro's journey. Combining breathing techniques with weapons and robots would be fascinating to say the least, but balancing the use of technology with discipline and skill would certainly be more difficult than what our heroes are used to. As they say, a weapon is better with a sword or a knife. Another problem arises even though Tanjiro has modern weapons and even surveillance tools to counter his enemy. But his ability to empathize with demons is at odds with the cold efficiency of modern demon-hunting tools, particularly AI robots that lack his compassion. This would lead to an internal conflict as Tanjiro weighs his values ​​against the changing demands of a technologically advanced time.

The Hashira would be no exception in changing their role within the Corps' elite warriors. With access to modern equipment, training, skills and strength could be complemented by technology, leading to new combat techniques and opportunities to collaborate with AI-powered allies. However, it is very likely that their reliance on tradition and deep connection to the history of demon slayers contrasts with the impersonal nature of technology, which would raise the question of how far they should go in embracing modernization.


How technology is changing the core of history

Nostalgia vs. Efficiency in Modern Demon Slaying

Part of the emotional appeal of Demon Slayer has to do with its historical background and the reliance on skill, tradition and willpower against demons. As much as the technology could lead to greater efficiency, it would also risk losing some of the raw and heartfelt battles that define every fight. Fans will be thrilled by the intensity of the hand-to-hand combat, the masterful swordsmanship, and the emotional arcs Demon Slayer They dedicate their lives to protecting humanity.


The modernized demon slaying would be less personal or nostalgic for audiences, especially longtime fans who love classic elements of the series. Part of the story's charm is watching Tanjiro grow and fight within the limitations of the historical tools and techniques. While modern technology could add exciting new layers, it could also change the emotional core of the show in some way Demon Slayer will never change, thereby losing its timeless appeal and leaving its fans wondering whether the new efficiency overshadows the beauty of traditional methods.
