Tanjiro’s scar is not just a scar, but also a Demon Slayer Mark that signifies considerable power. The scar changes and becomes a scar after Tanjiro’s battle with the Demon Hand, indicating a transformation. This mark is inherited and appears in specific hyperhuman circumstances, such as high heart rate and body temperature.
Warning: Contains SPOILERS for the Demon Slayer Anime and MangaDemon slayer poses a subtle question to the viewer in the form of what appears to be a scar on Tanjiro’s head, which will completely transform in season 1 into a different mark. Unlike the evolution of Tanjiro’s physical abilities – which is explained frequently throughout the series – Tanjiro’s markings are not fully mentioned. However, it will be made more clear and given more importance in the anime’s sequels.
So how did Tanjiro get his scar? It was initially explained as an injury he received while saving his brother from a falling kettle of boiling water. Thus, the fact that his scar changed in episode 4 after being hit by the Devil Hand on the tree means that the scar will change because this incident made the scar worse – because blood flowed from the spot. This.
But this makes no sense either intuitively or logically. The burn scar will not be transformed into a scar line by Tanjiro’s broken mask, nor will its surface area change. It doesn’t make sense if the scar becomes scarier.
The manga delves deeper into the Demon Slayer’s mark of Tanjiro
Instead, it’s worth considering that Tanjiro’s mark was never really a scar, and in its place is always the Demon Slayer Mark – something similar to the mark seen on various demons in the series. These signify considerable power in those marked with them, although for demons this power is often acquired through means other than their own, such as being infused with any amount by Muzan Kibutsuji. What blood? In the film, Tanjiro’s father, Tanjuro, has the same “scar” on his head as his son – and it seems the explanation for this is that they both got the same scar from boiling water. Thus, it is clear that this is a genetic trait.
With this in mind, his battle with the Hand Demon makes better sense, as this is the first truly powerful demon Tanjiro fights in Demon Slayer – even if it pales in comparison to later opponents This is his. In the manga, Tanjiro’s mark is given much more light – especially in explaining how the Mark manifests. Chapter 129 reveals that the Mark appears on people whose bodies undergo specific superhuman circumstances – with heart rates reaching or exceeding 200 BPM, and body temperatures reaching or exceeding 39 degrees Celsius. This would perfectly explain why the incident with the kettle triggered Tanjiro’s Mark, as both the kettle’s temperature and heart rate increased due to worry for his siblings. (and pain) will likely result in both.
Why didn’t Tanjiro’s scar change in Demon Slayer Part 3
Demon Slayer season 3 continues the manga’s next storyline, the Blacksmith Village Arc. In it, Tanjiro teams up with two Hashira, Mitsuri Kanroji and Muichiro Tokito, as well as Genya Shinazugawa to protect the village from attacks by Upper Green demons. While Tanjiro certainly faces some dangerous opponents, his scar remains more or less the same as before the Blacksmith Village arc. Instead, fans get the chance to see Tokito develop his own Demon Slayer Marks, which raises the question of what these marks are and causes Tanjiro to finally get some information about them in the arc. 4.
If Demon Slayer season 4 onwards continues to follow the plot of the original manga, not only will this be shown more clearly, but the Mark will become a much more important aspect of the plot for many reasons. For now, though, it’s worth noting that it’s more than just a cool-looking scar – because Demon slayerIts visual appeal and attention to plot details tend to go hand in hand.
