Age: 27 Height: 220cm..? (Not sure about the height) Breathing Style: Stone Breathing Characteristics: The Stone Hashira of the Demon Slayer Corps. He was born blind and was raised by a monk after his parents died. When a demon attacked, he killed it, but everyone except one child died. However, that child thought Gyomei had killed everyone, leading to his imprisonment. He was later scouted into the Demon Slayer Corps and became the first Hashira.

Age: 21 Height: 182cm..? Breathing Style: Water Breathing Characteristics: The Water Hashira of the Demon Slayer Corps. He lost his parents to demons at a young age but lived happily with his older sister. He became a disciple of Urokodaki, befriending Sabito and Makomo. However, during the Final Selection, Sabito died protecting Giyu, and Makomo was also killed by a demon. Since then, Giyu trained relentlessly to become the Water Hashira. After losing Sabito, he became largely emotionless and socially oblivious.

Age: 19 Height: 173cm..? Breathing Style: Love Breathing Characteristics: The Love Hashira of the Demon Slayer Corps. She has been a big eater since childhood and consumes an incredible amount of food (yet never gains weight). She possesses muscle density roughly eight times that of an average adult male. Her hair is pink with green tips because she ate so much of her favorite food, sakura mochi, that her hair color changed. (It was originally black). She once dyed her hair black to confess to a man she liked, but was rejected, so she joined the Demon Slayer Corps to find a husband(?). Her uniform is somewhat revealing because it was given to her by a perverted member named Masao Maeda. (Apparently, Shinobu burned the same outfit when it was given to her~)

Age: 15 Height: 163cm..? Breathing Style: Water Breathing, Sun Breathing Characteristics: An ordinary(?) member of the Demon Slayer Corps. About two years ago, Muzan killed his entire family except for Nezuko (who was turned into a demon), so he despises Muzan. He has an extremely kind personality (on the level of a saint). He travels with Nezuko, which almost got them both killed for violating Corps rules (they were saved thanks to Urokodaki). He used to carry a wooden box for Nezuko, but since she conquered the sun, he rarely carries it now. He is Urokodaki's disciple and initially used Water Breathing, but switched to Sun Breathing as it was better suited for him.

Age: 16 Height: 162cm..? Breathing Style: Thunder Breathing Characteristics: A perfectly ordinary member of the Demon Slayer Corps. Abandoned by his parents as a child, he was named by the villagers. He is a disciple of Jigoro Kuwajima. Although Thunder Breathing has six forms, he can only use the First Form: Thunderclap and Flash. He is obsessed with women and will chase after any pretty girl (to the point of asking for marriage upon first meeting). He likes Nezuko the most, which sometimes gets him scolded by Tanjiro. (+ His hair is yellow because he was struck by lightning during training.)

Age: 15 Height: 167cm? Breathing Style: Beast Breathing Characteristics: The member who causes the most trouble in the Demon Slayer Corps. Raised by wild boars without parents, he is illiterate. He wears a boar mask, which he says belonged to the boar that raised him. (He is handsome under the mask.) He always gets names wrong. (e.g., Tanjiro > Monjiro). According to Tanjiro, he gets it right about once every seven times. However, he is scared of Shinobu, so he calls her by her correct name.

Age: 18 Height: 151cm Breathing Style: Insect Breathing Characteristics: The Insect Hashira of the Demon Slayer Corps. As a child, she and her sister Kanae were nearly killed by a demon but were saved by the Stone Hashira. They promised to become Demon Slayers so that no one else would suffer like them. Kanae became the Flower Hashira, while Shinobu reached the rank of Kinoe. Around that time, they adopted Kanao, who was being sold into slavery. However, Kanae was killed by Upper Rank 2, Doma. Since then, Shinobu always wears a smile to carry on her sister's will. (She smiles even when she is angry.)
