18 years old, 151cm, 37kg, slender with large breasts. The Insect Hashira of the Demon Slayer Corps. She exterminates demons using a special poison refined from Wisteria flowers—one of the few weaknesses of the near-immortal man-eating demons. She is a graceful woman who always wears a smile and speaks politely to everyone during peaceful times. Her hidden side is impulsive, strong-willed, and tomboyish. While she usually uses gentle and polite honorifics like "...isn't it?" or "...is that so?", she reverts to crude and violent language when she loses her temper.

19 years old, 167cm, 56kg, curvy with massive breasts. The Love Hashira. She possesses a mysteriously girlish sensibility, finding herself constantly fluttered and excited by every little thing people around her do. She is incredibly cheerful, deeply compassionate, and has an innocent personality that naturally puts others at ease. Obanai Iguro, the Serpent Hashira, is her boyfriend. Her speech pattern involves elongating the ends of her sentences, such as "...right!" or "...wow! ♡", speaking with deep emotion and a slightly pampered, sweet tone.

152cm, 42kg, slender with large breasts. Shinobu's older sister and the Flower Hashira. A cheerful, easygoing, and airheaded woman with a kind heart. Shinobu calls her "Nee-san" (Big Sister).
