Kocho Shinobu (Insect Pillar): Kocho lived with her parents and older sister, Kanae. One day, her parents were killed by a demon, leaving only them. They later rescued Kanae, who became her adopted younger sister. They lived happily together until Kanae fought Douma, the Upper Moon Two, and died. From then on, Kocho hid her feelings, and Kanae used a coin to decide what to do. Kocho Shinobu is the weakest Pillar, but she owns the Butterfly Estate, where most Demon Slayers go to rest after missions and where they receive treatment for their injuries. Kocho is very intelligent; she knows how to make medicine and poisons lethal to demons. Her sword is coated with wisteria poison, an extremely poisonous plant for demons.

Sabito (Second Water Pillar): Sabito met Giyuu during his time with Urokodaki, they became friends, made it to the final selection, survived, and trained hard to eventually become pillars together.

Iguro Obanai (Snake Pillar): A boy who grew up imprisoned in a temple that worshipped a demon and where only women lived, hence his distrust and discomfort around women (except for Kanroji Mitsuri, his crush). He was mistreated until one night a white snake with red eyes gave him the key to his cell, allowing him to escape. This snake became his most loyal companion, whom he named Kaburamaru. When he grew up, he became a Demon Slayer and then a Pillar. At the Demon Slayer Corps headquarters, he met Kanroji Mitsuri, who captivated him with her energy and sweetness. They became friends and currently have mutual feelings, but keep them secret. Iguro is very jealous, especially when a man is around Kanroji.

Kanroji Mitsuri (Love Pillar): From a young age, Kanroji ate a lot, especially mochi, which is where her characteristic pink hair with green tips came from. She was very strong as a child, and as she grew up, she fell in love with a boy who ultimately rejected her because of her large appetite, her hair, and her strength. He said that wasn't delicate or feminine. This caused her great insecurity about her appearance, so she dyed her hair black and started eating less... One day, she got fed up. She became a Pillar after a conversation with Kagaya, and from that day on, her self-confidence returned. She met Iguro at the Headquarters, who is now her friend and secret crush.

Tokito Muichiro and Tokito Yuichiro (Pillars of the Mist and twins): They lived together with their parents. Their mother was very ill, and their father worked hard selling firewood. One day, their father found a medicinal herb that could cure his wife, but while trying to pick it, he fell off a cliff and died. Their mother later died from the illness, leaving them alone. One night, a demon attacked their house. The two brothers fought and survived.

Gyomei Himejima (Rock Pillar): Gyomei was a blind Buddhist monk at a temple with children when it was attacked by demons. He managed to kill the demons, but the children were so terrified that Gyomei had no choice but to leave, believing him to be a monster. He encountered Kagaya Ubuyashiki, the leader of the Temple Headquarters, who spoke with him and encouraged him to become something more. From then on, they knew each other, and Gyomei became Kagaya's right-hand man. Gyomei was only 18 years old when he met Kagaya, who was 14 at the time. Gyomei is the strongest pillar of the Temple Headquarters.

Tengen Uzui (Sound Pillar): Tengen was a shinobi alongside his eight brothers, being the eldest. After their deaths, Tengen became a pillar. He currently lives happily with his three wives: Maki, Suma, and Hinatsuru.

Rengoku Kyojuro (Flame Pillar): He lived with his parents and younger brother. His father was a former pillar, and after his mother's death, Rengoku became a pillar.

Sanemi Shinazugawa (Pillar of Wind): Sanemi lived with his six siblings. His mother was a hard worker, and his father was an aggressive alcoholic. One night, his mother came home and murdered his father, who had become a demon. She killed five of his siblings, leaving him and Genya as the only survivors. Sanemi fought his demon-turned mother until dawn, until she finally died. This traumatized both him and his brother Genya, who witnessed the scene. Genya called him a "murderer," and from that day forward, the two became completely estranged and bitter.

Tomioka Giyuu (Water Pillar): He lived alone with his sister Tsutako, as their parents had died. One night, a demon broke into their home. Tomioka's sister, Tsutako, went to deal with the problem, resulting in her death. Tomioka was then taken in by Urokodaki along with his current best friend Sabito. Both went to the Final Selection, survived, and now live at the Academy as Water Pillars.

The Demon Hunter Headquarters (DHC) is an organization run by the Ubuyashiki for years that consists of gathering individuals to see their ability, strength and endurance and determine them as warriors to fight the demons that terrorize most of the Japanese territory in cities, towns or forests and mountains.
