Koyoharu Gotouge, the creator of Demon Slayer, originally had a drastically different vision for Tanjiro Kamado. In the earliest drafts of the series, Tanjiro was not the kind-hearted warrior fans know today but was instead written as a villain. This alternate version explored a much darker path, where Tanjiro could have become a formidable antagonist rather than a heroic Demon Slayer.
The original concept leaned heavily into themes of vengeance and despair. Gotouge considered making Tanjiro a character who succumbed to darkness after witnessing his family’s slaughter. Rather than fighting demons to protect humanity, he was initially meant to embrace his rage, possibly even becoming a demon himself. However, as the story evolved, so did Tanjiro’s role.
A Shift from Tragedy to Hope

Had the original version been realized, Demon Slayer would have taken on a much more somber tone. A villainous Tanjiro would have drastically altered the series’ emotional core, shifting it from a tale of perseverance to one centered on destruction and revenge. His transformation into a hero instead introduced themes of resilience, kindness, and inner strength, which became defining traits of the story.

Gotouge ultimately chose to make Tanjiro a beacon of hope rather than despair. This decision allowed the series to highlight the struggles of those fighting against demons while maintaining an emotional depth that resonated with fans. Tanjiro’s unwavering compassion became the heart of the narrative, giving the story its uplifting and inspirational elements.
The Impact of Tanjiro’s Heroic Path

By shifting Tanjiro’s role, Demon Slayer became a story about overcoming pain rather than being consumed by it. His journey emphasized themes of empathy, determination, and sacrifice. If he had been written as a villain, the series might have followed a much bleaker trajectory, possibly focusing on his descent into darkness rather than his fight against it.
Tanjiro’s heroic nature has made him one of anime’s most beloved protagonists. His character stands as a testament to the idea that even in the face of immense suffering, one can choose kindness over cruelty. Gotouge’s final decision to make Tanjiro a hero instead of a villain helped shape Demon Slayer into the powerful and emotionally resonant story fans cherish today.
Studio Ghibli has long been synonymous with meticulous hand-drawn animation, where every frame is crafted with precision. Reports suggest that the studio once spent an entire year refining a single frame to meet its artistic standards. This level of dedication showcases the painstaking efforts behind traditional animation, a stark contrast to today’s rapid advancements in AI-driven techniques.
With artificial intelligence now capable of generating high-quality visuals in seconds, the animation industry is facing a transformative shift. What once required years of artistic labor can now be accomplished almost instantly. While this technology offers speed and efficiency, it also raises questions about the value of human craftsmanship in storytelling, particularly in studios known for their deep artistic heritage.
The Evolution of Animation Techniques

Studio Ghibli’s approach to animation prioritizes hand-drawn artistry, where each frame is carefully illustrated and painted to maintain a distinct visual charm. This meticulous process ensures that every movement, expression, and background detail contributes to the emotional depth of the story. Their commitment to this method is what makes classics like Spirited Away and My Neighbor Totoro visually timeless.

AI-generated animation, on the other hand, relies on algorithms to instantly create or modify frames. While this process speeds up production, it lacks the personal touch that defines Ghibli’s work. Many animators worry that the rise of automation could lead to a loss of artistic individuality, replacing heartfelt craftsmanship with formulaic efficiency.
The Debate Over AI in Animation

As technology continues to evolve, the animation industry faces a divide between tradition and innovation. AI-driven tools allow studios to produce content faster, reducing labor costs and streamlining workflows. However, purists argue that animation is more than just images—it is an emotional art form that requires human intuition, something artificial intelligence struggles to replicate.
Studio Ghibli’s year-long effort on a single frame symbolizes the dedication and patience that make traditional animation unique. While AI may offer new possibilities, the question remains: can it truly replace the human touch that gives animation its soul? The future of animation may lie in a balance between technological advancements and preserving artistic integrity.
