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.
