Tanjiro with his scars.
In chapter 128, vol. 10, a pillar meeting where all the pillars were present, Kagaya Ubuyashiki’s wife, Amane Ubuyashiki, notified everyone that the Love Pillar: Mitsuri Kamroji and the Mist Pillar: Muichirou Tokitou had also had marks! Everyone seemed shocked, including the two, while Amane continued asking them the condition to acquire them. Yes, you read it right. There are conditions to have them, and there is a history for the appearance of the scars! “During the Sengoku era,” Amane continued, “there were swordsmen of the first breath who was one step away from ending Kibutsuji Muzan. They all had marks that resembled Demon Crests.” Needless to say, she also shared a consistent knowledge with them, which states, “Once one person has that mark on them, it starts spreading to others, as if they’re resonating.”
Just the right and perfect explanation behind the scar, isn’t it? Also, as of now, Tanjiro is the first one to have ‘that mark’!

Demon Slayer
To those who are new to the anime Demon Slayer, here’s a sneak-peek to the story so far. Demon Slayer is about man-eating demons who roam around amongst normal humans only at night. It is about a young thirteen-year-old boy, Tanjiro Kamado, who lost his family to a demon’s attack. Only his younger sister, Nezuko Kamado, lived. He carries her on his back and walks down the mountain, far away, leaving his dead family behind, and tries to save her. While traveling down, he meets Giyu Tomioka (The Water Pillar), and while trying to kill Nezuko because she was slowly turning into a demon, Tanjiro begs and promises to Giyu that Nezuko will never kill a human, nor will he ever let her do so. He wants to save her, no matter the cost, and tries to find a cure to turn her back into a human!

The Kamado Family
Tanjiro loved his family. He looked up to his father, Tanjuro Kamado, who had passed away years ago. His mother was as gentle as a breeze. His five siblings, including Nezuko, were his world. His happy family shattered right before his eyes when he saw them covered in blood. He froze but could notice that Nezuko was still warm, and if he made his way to get help, he could at least save her! He intended to save her and turn her back into a human again.
