The World of "KNY"

Tanjiro Kamado is the main character of the anime and manga series Demon Slayer: The Last Airbender.
A young man who became a demon slayer to save his younger sister, Nezuko, who was turned into a demon and the rest of his family was killed. His main goal is to restore his sister to human form and avenge his family.

Shinobu Kocho is the Insect Pillar. Polite, smiling, and outwardly calm, she is inwardly determined to avenge the deaths of her loved ones on demons. Physically weaker than the other Pillars, she cannot decapitate a demon, so she relies on poisons. Her "Insect Breath" is a quick, precise stab that injects the enemy with a wisteria-based toxin deadly to demons.

Gyomei Himejima—the Stone Pillar. Outwardly, he appears formidable due to his powerful build and stern appearance, but in reality, he is very kind and deeply religious. Despite his blindness, he is incredibly dangerous in combat. He uses not a conventional sword, but an axe connected by a chain to a spiked ball, and the "Stone Breathing" technique—strikes comparable in force to collapsing rock.

Sanemi Shinazugawa is the Wind Pillar. Brash, hot-tempered, and at times rude, yet selflessly devoted to the extermination of demons. His "Breath of Wind" makes his attacks swift and destructive, like a whirlwind. He possesses a rare ability: his blood attracts and irritates demons.

Tengen Uzui—the Pillar of Sound. A flamboyant, eccentric, and confident warrior who calls himself the "god of festivals." He loves all things flashy and loud, but is also a skilled tactician. He uses the "Breath of Sound": using vibrations and explosive techniques, he reads his opponent's movements and delivers devastating blows with two massive blades.

Mitsuri Kanroji is the Pillar of Love. A kind, emotional, and very sensitive girl who appears fragile but possesses incredible physical strength and flexibility. Her "Breath of Love" is an adaptation of "Breath of Flame," combining powerful strikes with fluid movements.

Obanai Iguro is the Snake Pillar. Pragmatic, cautious, and very attentive to detail. He always appears with his snake, Kaburamaru, which helps him read his enemies' movements. His style is "Snake Breath": he uses a curved blade and delivers sinuous, unpredictable strikes.

Muichiro Tokito is the Mist Pillar. A young and seemingly aloof swordsman, he often seems lost in the clouds. Due to memory loss, he initially displays no emotion, but in battle he unleashes immense power. His "Mist Breath" allows him to confuse opponents and strike from unexpected angles.

Kyojuro Rengoku is the Flame Pillar. Energetic, straightforward, and incredibly dedicated to his duty, his fighting spirit and "giving it his all" philosophy inspire those around him. He uses the "Breath of Flames," creating fiery sword strikes; he is known for his tenacity in battle.

Giyu Tomioka is the Water Pillar. He appears cold and aloof, but possesses a strong sense of justice. He was the one who spared Nezuko and directed Tanjiro to Urokodaki. His technique, "Water Breathing," makes his movements fluid and incredibly precise, and his strikes powerful.
