Tanjiro Kamado is the main protagonist in the popular anime and manga series “Demon Slayer: Kimetsu no Yaiba.” One of the most noticeable physical features of Tanjiro is his scar on the right side of his forehead, which has become an iconic part of his character design. The scar has been a topic of discussion among fans, and some have noticed that it has undergone some changes throughout the series. In this essay, we will explore the reasons why Tanjiro’s scar changed and the significance of those changes.

To understand why Tanjiro’s scar changed, we first need to look at the events that led to him getting the scar. In the first episode of the series, we see Tanjiro’s family being attacked and killed by demons, with only Tanjiro and his sister Nezuko surviving. During the attack, Tanjiro’s forehead was struck by a demon’s claw, leaving him with a deep scar. This event marks the beginning of Tanjiro’s journey as a Demon Slayer, as he sets out to avenge his family and protect his sister.
The initial design of Tanjiro’s scar was a simple straight line that ran vertically down his forehead. However, as the series progressed, fans noticed that the scar began to change shape and become more complex. In the later episodes and manga chapters, the scar started to resemble the shape of a sun with two distinct lines branching out from the center. This change was not a mistake or a random decision by the creators of the series; it was intentional and had a purpose.
One reason why Tanjiro’s scar changed is to symbolize his growth as a character. In the beginning, Tanjiro was a young boy who had just lost his family and was determined to become a Demon Slayer to protect his sister. He was inexperienced and naive, and his scar reflected that. However, as he faced more challenges and fought stronger demons, he grew stronger and wiser. The changing shape of his scar represents his growth and development as a character, as he becomes more skilled and experienced in his role as a Demon Slayer.
Another reason why Tanjiro’s scar changed is to show his connection to the sun. In Japanese mythology, the sun is a symbol of strength and perseverance, and it is often associated with heroes and warriors. Tanjiro’s scar resembles the shape of the sun, which symbolizes his strength and determination in the face of adversity. It also represents his connection to his family, who he lost in the demon attack, as they were known as the “Sun Breathing” family. The changing shape of his scar could indicate that he is becoming more in tune with his family’s legacy and power.
Additionally, the change in Tanjiro’s scar could be a subtle nod to the themes of the series. “Demon Slayer: Kimetsu no Yaiba” is a story about fighting against evil and overcoming obstacles, and the changing shape of Tanjiro’s scar could be a representation of that theme. Just as Tanjiro’s scar evolves and changes over time, so too does his journey as a Demon Slayer. He faces new challenges and overcomes them, just as his scar transforms and becomes more complex.
In conclusion, the reason why Tanjiro’s scar changed in the series is multifaceted. It represents his growth as a character, his connection to the sun and his family’s legacy, and the themes of the series. The changes in the scar are intentional and serve to enhance the character design and the overall storytelling of the series. Fans of “Demon Slayer: Kimetsu no Yaiba” will continue to watch Tanjiro’s journey and the evolution of his scar with great interest.
