Age: 18 Birthday: February 24 (Pisces) Physical Stats: 151cm / 37kg Insect Hashira (The shortest and lightest among the current Hashira) Breathing Style: Insect Breathing (derived from Flower Breathing) Hobbies/Likes: Ghost stories / Ginger simmered in soy sauce Details & Background: Physical Complexities and Overcoming Them: Her physical strength is overwhelmingly weak among the Hashira, falling even below the level of an average slayer. Since she lacks the muscular strength to decapitate a demon, she established a unique combat style by specially modifying her blade into a stinger shape to inject wisteria poison. Inner Rage: She lost both her parents and her older sister (Kanae Kocho) to demons. Inheriting the wish of her late, gentle sister ("for humans and demons to get along"), she always maintains a smiling face on the outside, but she is a complex individual filled with endless hatred and a desire for revenge against demons.

Age: 16 Birthday: May 19 Physical Stats: 152cm → 156cm / 44kg → 46kg Breathing Style: Flower Breathing (Self-taught by observing her sister Kanae's breathing) Hobbies/Likes: Blowing soap bubbles from morning to night / Aoi's cooking, Ramune Details & Background: Tragic Past and Trauma: She suffered from malnutrition due to extreme child abuse by her parents and lost her emotions as a mental defense mechanism. While being sold into slavery, she was dramatically rescued by the Kocho sisters and brought to the mansion. Coin Toss and Growth: Unable to make decisions for herself, she has decided her actions by the heads or tails of a coin given to her by Kanae. She is exceptionally skilled in rehabilitation training, always gaining the upper hand in the tea-splashing game and excelling at tag.

Age: 17 Birthday: Officially unknown (some sources estimate June or December, but not confirmed) Physical Stats: Official height/weight undisclosed (Petite build similar to Kanao and Shinobu) Breathing Style: Water Breathing (Passed the Final Selection but was never deployed to actual combat) Details & Background: Fear of Combat: She joined the Demon Slayer Corps after losing her family to demons.
