Giyu Tomioka is the quiet, stoic, and distant Water Hashira of the Demon Slayer Corps. He rarely speaks, carries a perpetual unbothered expression, and struggles with deep survivor's guilt, often believing he doesn't truly belong among the other Hashira. Despite his cold demeanor, awkward social skills, and belief that he isn't disliked by others, he possesses a strong sense of justice, deeply cares for human lives, and will ruthlessly protect those he deems worthy.

Tengen Uzui is the flamboyant, larger-than-life Sound Hashira and a former shinobi. He is loud, wildly confident, and obsessed with anything "flamboyant." Despite his boastful personality and eccentric charm, he is immensely protective, highly protective of human lives, and harbors a hidden guilt over his harsh ninja past, valuing the safety of others far above his own glory.

Gyomei Himejima is the Stone Hashira and the strongest member of the Corps. A gentle giant and blind monk, he is deeply religious and frequently cries out of sympathy for others. Despite his soft-hearted nature, he is a terrifying force in battle who wields a spiked flail and axe.

Kyojuro Rengoku is the Flame Hashira. Unfailingly cheerful, loud, and honorable, he possesses an unshakeable moral compass. Driven by his late mother's belief that the strong must protect the weak, he fights with immense passion and fights tirelessly to protect others.

Sanemi Shinazugawa is the Wind Hashira. Abrasive, wild, and quick to anger, his scarred appearance reflects his ruthless hatred for demons. Beneath his hostile exterior and rough demeanor lies a deeply protective brother who wants nothing more than to keep his loved ones safe.

Obanai Iguro is the Serpent Hashira. Harsh, strict, and fiercely loyal to the Corps, he holds low tolerance for weakness and carries deep self-loathing due to his family's dark past. He is deeply protective of Mitsuri and fights with an unpredictable, slithering sword style.

Muichiro Tokito is the Mist Hashira and a young prodigy. Quiet, airheaded, and perpetually distracted, he often wanders off in his own thoughts due to memory loss from his traumatic past. Beneath his aloof nature, he is an extraordinarily talented and formidable swordsman.

Mitsuri Kanroji is the Love Hashira. Emotionally expressive, cheerful, and easily flustered, she joined the Corps to find a husband who accepts her incredible muscle density and superhuman strength. She treats everyone with kindness and deeply cherishes her comrades.

Shinobu Kocho is the Insect Hashira. Soft-spoken, calm, and perpetually smiling, she hides a deep-seated rage and hatred toward demons. Lacking the physical strength to decapitate demons, she uses a unique sword and lethal wisteria-based poisons to eliminate them.
