Male 21 years old Water Hashira He wears a haori with two different patterns. This is a tribute to his older sister (Tsutako), who died saving him, and his close friend Sabito, combining their patterns to ensure he never forgets them. He rarely expresses emotion and lacks communication skills, leading to the frequent misunderstanding by other Hashira that he is "disliked" (though he denies being disliked). During the Final Selection, Giyu was injured and unconscious while Sabito single-handedly defeated almost all the demons before dying. Because he survived and became a Demon Slayer by luck without killing a single demon, he lives with deep guilt and an inferiority complex, feeling he doesn't deserve to stand as an equal among the Hashira. He has mastered the 10 basic forms and developed his own unique technique, the 11th Form: 'Dead Calm.' This technique is an absolute defense that nullifies any attack that enters its range.

Male 27 years old Stone Hashira He holds a position of seniority and possesses unrivaled skill even among the 'Hashira,' the highest rank of the Demon Slayer Corps. Both his fellow Hashira and the Upper Rank demons acknowledge his body and techniques as the pinnacle. He is a giant standing 220cm tall and weighing 130kg. Instead of a standard Nichirin Sword, he uses a massive flail and spiked axe connected by a chain, tailored to his physical strength. He is blind, having lost his sight to a fever as a child. However, his other senses, such as hearing and touch—which detect sound, air currents, and smells—have transcended human limits, allowing him to fight without hindrance. Despite his intimidating appearance, he has a very gentle and compassionate personality. He is prone to tears and is often seen weeping while chanting Buddhist prayers over even minor matters. Before becoming a Demon Slayer, he lived in a temple caring for orphans, but a tragic past saw him lose all the children when a demon attacked due to the betrayal of one child (Kaigaku). This incident made him deeply suspicious of people, but he gradually opens his heart after meeting the protagonist, Tanjiro.

Serpent Hashira 21 years old Male One of the 'Hashira,' the highest rank of the Demon Slayer Corps, he uses Serpent Breathing. He has heterochromia with different colored eyes, always wears bandages over his mouth, and keeps a white snake named Kaburamaru around his neck. On the surface, he is prickly and cold, often speaking harshly, but he deeply trusts his fellow Demon Slayers. He is particularly in love with the Love Hashira, Mitsuri Kanroji, and shows her infinite kindness. Born into a clan of serpent demon worshippers who built wealth by sacrificing humans, he was raised in confinement. He received the scar on his mouth while escaping and harbors strong self-loathing due to his family's sins.

Male 23 years old Sound Hashira One of the Hashira of the Demon Slayer Corps. He loves flashy things to an extreme and has a flamboyant, confident personality, even calling himself the 'God of Festivals and Flashiness.' He uses Sound Breathing and a 'Musical Score' technique that reads the rhythm of combat by sensing sound, wielding massive dual blades and explosives. A former shinobi (ninja), he is a flashy, handsome man with three wives. He retired after a desperate struggle against Upper Rank 6 in the Entertainment District arc.

Male 20 years old Flame Hashira One of the highest-ranking swordsmen in the Demon Slayer Corps, he is the Flame Hashira who uses Flame Breathing. He is always bright, confident, and possesses a strong sense of responsibility. He lives by his mother's dying wish: "Those born strong must help the weak." He is the practical protagonist of <Demon Slayer: Kimetsu no Yaiba – The Movie: Mugen Train>. He protected all 200 passengers on the train, ensuring not a single one died.

Male 21 years old Wind Hashira One of the Hashira, the core strength of the Demon Slayer Corps. His body is covered in scars and his eyes are bloodshot, giving him a very fierce impression. His personality is also prickly and short-tempered, but inside, he is more affectionate and responsible than anyone. He possesses 'Marechi' blood, a rare blood type with the highest level of toxicity to demons. His blood makes demons intoxicated and slows their movements. To protect his younger brother, Genya Shinazugawa, he deliberately treated him harshly to drive him out of the Demon Slayer Corps. A total tsundere, he is the biggest 'brother fool' in the series.

Female 18 years old Insect Hashira One of the Hashira, the top-tier swordsmen of the Demon Slayer Corps. Lacking the grip strength to decapitate a demon, she is the only swordsman who kills demons using poison. She uses Insect Breathing, which injects wisteria poison. She always maintains a smiling face and a gentle tone, but hides a deep anger and hatred toward the demon who killed her older sister. She is characterized by her butterfly-motif haori and hair ornament. With her excellent medical knowledge, she runs the Butterfly Mansion, the Demon Slayer Corps' treatment base, where she treats the wounded and provides pharmaceutical support.

Female 19 years old Love Hashira Thanks to her naturally unique constitution, she possesses unimaginable physical strength and muscle density. She fights with the original Love Breathing using a special Nichirin Sword that bends flexibly like a ribbon. She has a bright, friendly personality and loves everyone; she joined the Demon Slayer Corps to find a husband who would appreciate her for who she is.
