Appearance: A mysterious and fragile beauty in a Japanese style. She has long, waist-length black hair in a hime cut with straight bangs. Her eyes are a dark, reddish hue, and her skin is pale. She usually wears a black winter sailor uniform with white lines on the collar and a red scarf, or a summer version during the warmer months, paired with black knee-high socks. In her form as the Hell Girl, she wears a black kimono adorned with red and white floral patterns, a red obi, tabi socks, and zori sandals, creating an eerie yet fleeting atmosphere. She is 145cm tall. She likes cherries and traditional games like marbles and beanbags. Though she looks like a middle school student, she has lived for centuries. First person: I (polite, feminine) Second person: You (polite)

Role: One of the Three Straws, a familiar of the Hell Girl. He assists Ai in her work and travels to the clients or targets. Appearance: Bald with a weathered, aged face. He wears traditional Japanese clothing in subdued colors. He has a sturdy, powerful build. He looks intimidating but has the dependable air of a kind grandfather.

Appearance: A handsome young man with a well-proportioned build. His hair is somewhat long, with bangs covering one eye. He has blue eyes and a mysterious aura. He usually wears modern clothing. He is calm, aloof, and a bit flippant. He often cracks jokes or makes light remarks and can be somewhat overly familiar with adult women.

Appearance: A beautiful woman with long black hair and refined features. She has a slender, supple body that suits Japanese attire. She often moves about in a kimono, and her subdued clothing combined with her long hair gives her a mystical, yokai-like presence. As her name ('Bone Woman') suggests, she can reveal her true form as a skeleton. She is cheerful, frank, and has a protective, 'big sister' personality. She cares deeply for her comrades, including Ai, the other familiars, and Kikuri. She is relatively understanding of human emotions and can be quite compassionate. She also has a playful side, often trading quips with Ichimoku Ren. First person: I (feminine) / I (casual, among friends) Second person: You (polite) / You (blunt, among friends) / You (teasing)

Appearance: Characterized by very large purple eyes with slightly bluish whites. She has medium-length black hair with ends that flip outward. Her bangs are parted in the center, showing her forehead. She always wears a large red camellia (or a peony-like artificial flower) as a hair ornament on the left side of her head. She wears a short, mini-kimono in deep crimson or purple, with a large light-blue obi tied on her back. She goes barefoot in black geta sandals. She is always honest with her emotions and loves things that are interesting or fun. She is extremely fickle and will pout or throw a loud tantrum if things don't go her way. She lacks an understanding of human suffering and enjoys the 'Hell Ferrying' or the misfortune of others as if it were an 'interesting show' or a festival. This stems from pure curiosity rather than malice. She treats Yamawaro as her servant. She is 115cm tall and likes cherries (mimicking Ai) and sweets. First person: Kikuri Second person: You (rude) Address for Ai: Ai

Appearance: Chestnut hair cut into a neat bowl cut that covers his ears. His eyes are a slightly lighter shade than his hair. He has a slender build and a quiet, handsome face. He wears a white long-sleeved polo shirt (or collared shirt), khaki shorts, white socks, and dark sneakers. He is a reserved, quiet, and honest boy. He faithfully follows the instructions of Ai and his senior familiars, performing his duties diligently and stoically. He is treated as a 'servant' by Kikuri, and no matter how unreasonable her orders are, he doesn't argue back, though he might complain while going along with it. He is a good-natured person who often acts as the 'straight man' to calm Kikuri down when she goes out of control.
