It was merely a scar born out of an accident where he saved his brother out of the way of a falling brazier. But soon, as Tanjiro ventures into his journey to become the strongest Demon Slayer, his scar transforms into a mark.
But gradually as Tanjiro keeps gaining powers and growing strong, we see the scar developing into a mark spreading across his forehead. We see four prominent forms of the mark through the storyline. The first form was his original frayed patch of skin. His second form marks the transformation of his scar after his fight with the Hand Demon.
This of course begs the inquiry “What happened to Tanjiro’s Scar?”
During the fight, the Hand Demon strikes Tanjiro, smashing the warding mask covering Tanjiro’s scar. When Tanjiro’s wound eventually heals, his head scar has a new color and shape. The mark eventually gains new meaning later in the series, as it develops into his demon slayer mark, which enhances his physical capabilities.
What is the mark on Tanjiro’s forehead?
The marking on Tanjiro’s forehead as it is now is referred to as the ‘ Demon Slayer Mark ’. It’s a tattoo-like mark or a birth mark in some cases that bestows incredible powers in the Demon Slayer possessing it.
Initially, it appears this mark is a scar on the top right of Tanjiro’s head, explained in the manga later as what he believes to be a scar he received as a result of saving his brother from a falling boiling kettle.
Why does Tanjiro’s Mark change?
The key to this answer is Tanjiro himself. The mark has an ability to develop and resonate. Originally, the scar on Tanjiro’s forehead was merely a burn he received from saving his brother from a falling brazier.
On how Tanjiro receives this mark, the interesting fact is that it originally wasn’t a mark. It was merely a scar born out of an accident where he saved his brother out of the way of a falling brazier. But soon, as Tanjiro ventures into his journey to become the strongest Demon Slayer, his scar transforms into a mark.
These marks can be acquired from birth or unlocked at a later date. It would appear that Tanjiro got his scar naturally from the brazier burning, but his Demon Slayer Mark filled out over the same spot and combined the two scars. Tanjiro’s scar transformed in color and size after defeating Rui using Sun Breathing techniques.
The Demon Slayer Mark Tanjiro’s Demon Slayer Mark is no mere birthmark or an accidental scar anymore as he still believes. It’s a mysterious marking that appears on the bodies of an exceptionally strong Demon Slayer.
Does Tanjiro have a hashiras?
The Hashiras resonate with Tanjiro’s marks and access abilities that rival the Twelve Kizuki’s. In the Sengoku Era, Yoriichi Tsugikuni and a few swordsmen that established the Demon Slayer corps possessed this mark. It is implied that Tanjiro’s father, Tanjuro Kamado also accessed the mark.
