Tanjiro

Tanjiro grew up in the mountains with his parents and siblings, the eldest child in the Kamado family. His father, Tanjuro, died of illness when Tanjiro was very young, so Tanjiro assumed the role of breadwinner. He loved his family dearly and cared for them as best he could. One day, one of Tanjiro's brothers accidentally knocked over a hot teapot, and trying to protect the child, Tanjiro received his scar on his forehead.

Tanjiro sold coal in the nearby town to earn money for his family, and it seemed he showed up there quite often, as the townspeople easily recognized him and asked for his help.
One winter morning, Tanjiro is about to go to a nearby town to sell charcoal, but his younger sister, Hanako, and brother, Shigeru, hold him back, begging him to take them along. Their mother intervenes, saying Tanjiro won't be able to carry them if they're tired. Takeo is disappointed, as he had planned to chop firewood with his older brother today. As Tanjiro heads off to town, his sister, Nezuko, carrying her younger brother, Rokuta, bids him farewell.
Returning home the next day, Tanjiro finds his entire family, except for Nezuko, murdered. Tanjiro takes his sister and plans to find the nearest doctor, but Nezuko, transformed into a demon, attacks Tanjiro. While Tanjiro tries to fend off his sister's attack, Giyu Tomioka attacks Nezuko from behind. However, Tanjiro intervenes and prevents Nezuko from being killed. The swordsman asks Tanjiro why he is protecting a demon. Tanjiro tells him it's his sister. Looking at Nezuko's distraught state, Giyu questions this and quickly takes the demon from Tanjiro's hands. However, Tanjiro begs Giyu to spare his sister, hoping to find a cure for her in the future.

Tanjiro is very kind by nature. "A man with kind eyes" is how he is described. Very determined and goal-oriented. Although Tanjiro himself is relatively strong, he is not afraid to ask others for help when needed. He is always ready to stand up for those around him, but protecting his sister is his highest priority.

An important character trait of Tanjiro is his compassion, which is often shown even in relation to demons. However, during his service in the ranks of the fighters, Tanjiro gains experience, becomes more calculating and decisive. Thanks to his courage and desire to protect the weak, he meets opponents with respect and dignity, be they humans or demons.

Tanjiro is a young man with tanned skin and an athletic build. He has tousled black hair with maroon tips that is slicked back and large, dark red eyes. On the left side of his forehead is a burn scar that has darkened and changed shape since his battle with the Hand Demon during the final selection.

Tanjiro wears a dark red Demon Slayer uniform with a black and green checkered haori over it. He also wears hanafuda earrings with a red sun design.

After killing Muzan, he turned Tanjiro into a demon, which caused the guy's right hand to regenerate, and his appearance underwent some changes: the fighter mark grew all over his face and looked more like tongues of flame, his eyes became brighter, and his pupil narrowed.
