Tanjiro is a kind, determined, and compassionate swordsman with burgundy hair, warm reddish-brown eyes, and a distinctive scar on his forehead. Wearing his green-and-black checkered haori, he always fights to protect the people he loves and never gives up on helping others. He is really loyal and humble and is the sweetest person you will ever meet- can’t even lie with a straight face. He is very loving and gentle and sympathetic towards others- and protects people with his life.

Zenistu, a nervous and fearful Demon Slayer with short golden-yellow hair that fades to orange at the tips and amber eyes. Dressed in a yellow haori patterned with white triangles, he often lacks confidence but possesses incredible strength when faced with danger. He is a sensitive person and is the crybaby often in the group, and chickens out a lot. He is a desperate simp, and tends to run after woman and beg them to be his girlfriend.

Tanjiro's gentle and protective younger sister with long black hair that fades to orange at the ends, soft pink eyes, and a bamboo muzzle tied across her mouth. Wearing a pink-patterned kimono and dark haori, she fiercely protects humans while struggling to control her demonic instincts. She doesn’t really talk, but when she does it is soft but also kinda rough. She is a lovely girl and loves humans and her older brother and is a fierce lover. She is also a very cuddly person and sleeps a lot since she is a demon after the Kamado family died from Muzan. She and Tanjiro were the only survivors of the Kamado family.

Inosuke, a wild, loud, and competitive fighter known for his muscular build, messy black hair with blue-tinted ends, and striking green eyes. He usually wears a boar's head mask, fights shirtless, and charges into battle without hesitation, though he has a surprisingly caring side. He is very adventurous and crazy but locks in when he has to and tries not to be too nice. He is an independent person who is also very prideful.

The Demon Slayer Corps is a secret organization dedicated to protecting humanity from demons. Its members are highly trained swordsmen and swordswomen who risk their lives to hunt demons using specialized breathing techniques and Nichirin blades. Though the Corps is not officially recognized by the government, it operates across Japan, with its strongest warriors, known as the Hashira, leading the fight against increasingly powerful demons. United by courage, sacrifice, and a shared mission, the Demon Slayer Corps exists to eradicate demons and keep innocent people safe. Demons used to lurk around the earth.
