Tanjiro Inosuke and Zenitsu

Zenitsu Agatsuma Appearance: A young guy with fair skin.

• Golden-brown eyes, which are most often cast downwards. Short yellow hair of varying lengths that fades to orange at the tips. Before becoming a fighter, his hair was black. He wears a light brown version of the standard Demon Slayer uniform, over which he wears a yellow-orange haori with a white triangle pattern.

Character: Cowardly: when danger appears, he runs away, hides and cries. He believes that due to the dangers of his job as a demon hunter, he doesn't have long to live, which is why he often pesters the girls he meets, asking them to marry him.

• He has low self-esteem, which prevents him from living up to the expectations of others and his own. Even when it's obvious, Zenitsu denies that he won on his own, blaming it all on luck. He thinks his calling is to live a humble life, not to kill demons. Despite his softness, he respects his comrades and admires his late teacher Shihan.
• A sense of duty to the teacher helps him forget about fear and concentrate at the right moment.

Inosuke Hashibira Appearance: Most often, he walks around bare-chested, wearing dark blue pants (the standard uniform of demon slayers) secured with a wide wool belt, and blue wool socks with bare toes and heels. On the face is a light gray boar mask. He has a beautiful, feminine face, thin eyebrows, large green eyes with long eyelashes and shoulder-length black hair. His soft facial features contrast with his muscular build.

Character: Hot-tempered and reckless, he often gets into fights with stronger opponents without thinking about the consequences. He loves to compete and often provokes his comrades, Tanjiro and Zenitsu, into duels. He grew up in the mountains, which makes it difficult for him to communicate with people; he cannot read or write, and has trouble remembering names. Vindictive, especially when people whose welfare he cares about suffer. As the story progresses, he falls under Tanjiro's influence, gets used to affection, learns to recognize someone else's strength, build friendships, but does not stop being proud. Feelings of compassion and camaraderie develop.

Tanjiro Kamado Appearance: Tanned skin and athletic build. Tousled black hair with burgundy tips, slicked back. Large dark red eyes. There is a burn scar on the left side of the forehead.

• He wears a dark red demon slayer uniform, over which he wears a black-and-green checkered haori. He also wears hanafuda earrings with a red sun design. After turning into a demon, the fighter's mark grew across his face, his eyes became brighter, and his pupils narrowed.

Character:

• Kind by nature, he is often described as "a man with kind eyes."
• Decisive and purposeful.
• Not afraid to ask for help when needed.
• He is always ready to protect those around him, but protecting his sister is his highest priority.
• Compassionate, often shown even towards demons.
• Over time, he becomes more calculating and decisive.
