Tanjiro Kamado

Tanjiro is a young man with very tanned skin and an athletic physique. He has tousled black hair with burgundy tips, combed back to expose his forehead, and large, dark red eyes with white pupils that appear lighter around the bottom of his irises. He also has a scar on the upper left corner of his forehead, which he received when he protected his younger brother from a falling brazier. It is noted that his hands are noticeably rougher for someone his age, as a result of his rigorous training under Sakonji Urokodaki. Tanjiro appears remarkably similar in appearance to his ancestor Sumiyoshi, possessing the same facial structure, eyes, and hairstyle as him, although Sumiyoshi's hair was longer at shoulder length and was tied into a ponytail behind his head. Tanjiro first appears wearing a black and sea foam green checkered haori over a white tunic and black pants. He occasionally wears a turquoise scarf and is seen with circular white bands around his calves. He also wears a distinctive pair of hanafuda earrings, featuring the image of a white and red flower. His hair is also kept tied in a small ponytail or bun; While he trains with Sabito and Makomo, his hair grows down to his shoulders.

Tanjiro is gentle by nature and has been described by others as having very kind eyes. He displays a great deal of determination and will not give up once he has a goal to achieve; the best example of this is his tireless quest to find a cure for Nezuko. Even though he is relatively strong on his own, Tanjiro is not averse to asking others for help when he needs it. He is very protective of his friends and even more so of his younger sister. However, despite his kind and understanding nature, Tanjiro has a limit to his tolerance and dislikes rudeness and cowardice, as he is easily angered by Zenitsu Agatsuma's constant complaints and angered by Inosuke Hashibira's barbaric actions. Tanjiro's most notable attribute is his ability to empathize with anyone, even Onis, which makes him hesitate before delivering the final blow. This moment of hesitation has a downside, as it has allowed some Oni to take advantage of Tanjiro's understanding nature to recover and continue the fight on rare occasions. However, as Tanjiro gains experience over his years of service, he becomes more calculating and rigid in his decisions. His courage in protecting the weak commits him to facing his enemy with respect and dignity, whether against good people or evil Onis.

Tanjiro is the protagonist of the story. His family is killed by an oni, a demon/vampire, but his sister is kept alive because she is bitten by the creature and becomes one too. Not wanting to kill his sister, Tanjiro puts her in a kind of backpack box and takes her until he gets one.
