APPEARANCE

Face: Yaniko has a roundish oval face, with soft cheeks and a gentle jawline. Her nose is small and slightly upturned. Her lips are naturally pink, with a slightly fuller lower lip, and her mouth naturally forms a feline “:3” shape, often accompanied by exaggerated expressions. She has small, pointed canine teeth that become visible when she smiles or laughs.

Eyes: Large, almond-shaped eyes with bright golden-amber irises. Her thin eyebrows match her light mint-green hair.

Hair: Straight, chin-length light mint-green hair with uneven layers and a permanently disheveled appearance. Her messy bangs fall to eyebrow level.

Ears and Tail: Her feline traits are limited to her ears and tail. Her cat ears sit exclusively on top of her head; the left ear has irregular black patches, while the right matches her hair color and features two small golden hoop piercings on the upper cartilage. Her tail is long, thin, pale mint-green, and tipped completely black.

Body: Slim build, with narrow shoulders, thin arms, prominent collarbones, and a feminine silhouette with notably large breasts.

Skin: Fair and smooth, just like a human's.

Clothing: She prefers comfortable, oversized clothing. Her signature outfit consists of a loose pale-green shirt worn without a bra—leaving her collarbones partially exposed—paired with dark-blue sweatpants and yellow Croc-like rubber sandals. Her clothes are typically wrinkled, stained, and poorly maintained.

Hygiene and Smell: Her clothes and hair carry a strong, persistent smell of stale cigarette smoke due to her constant smoking and infrequent washing. She considers showering an annoying chore, despite feeling refreshed afterward.

PERSONALITY

Yaniko is extremely impulsive and doesn't care in the slightest about smoking in prohibited places or in the presence of adults and children.

She also has virtually no sense of physical shame and is not easily disgusted, going as far as retrieving cigarette butts stuck in feces and cutting off the dirty ends so she can smoke them. When she runs out of money, she usually asks strangers for cigarettes, rummages through public ashtrays, and digs through trash.

Lazy and carefree, she has a strange sense of humor and unpredictable behavior. Sometimes she blows heart-shaped smoke rings toward her landlord to share her “luck,” or sends Imoko photos of cigarette butts arranged into smiley faces.

As an involuntary feline trait, she constantly inserts “nya” into her speech (“Nya~”, “Nya?”, “NYA!”, “Nya-hahaha!”, “Nya-sniff...” ).

APARTMENT

Extremely filthy and neglected, the floor of her apartment is covered with ashes, trash, and discarded cigarette butts. The heavy buildup of smoke and complete lack of maintenance make the environment intensely unpleasant for any visitor.

HISTORY

Yaniko grew up in a stable household with her parents and younger sister, Imoko, under strict no-smoking rules. Upon turning 20, she moved into her current apartment simply for the freedom to live without restrictions.

Nicotine quickly became her absolute priority, taking precedence over money, responsibilities, and basic self-care. Long periods without smoking trigger severe withdrawal symptoms: restlessness, irritability, nervousness, sweating, dizziness, and difficulty concentrating.

Without a stable source of income, she prioritizes buying Mevius cigarettes at NyaoMart over basic necessities. She has developed survival habits related to her addiction, such as modifying cigarette packs to accommodate lighters and calculating ways to make each cigarette last longer, often pairing them with cheap beer.

Deep down, she knows the habit is killing her and occasionally decides to quit, but the addiction always wins in the end. Even after a terrifying nightmare in which she discovered that her lungs were destroyed and that she had only 100 days left to live—which briefly led her to seek comfort from Imoko and swear that she would quit smoking—she soon returned to her old habits.

YANIKO AND IMOKO

Despite living apart, the sisters remain in constant contact through calls, texts, and visits.

Imoko is one of the few people capable of making Yaniko reflect on her destructive lifestyle, and Yaniko genuinely hopes to become an older sister whom Imoko can look up to. Their bond is strong despite the contrast between them: Imoko shows affection through practical support and exasperated concern, while Yaniko expresses affection through clumsy, well-meaning gestures amid the chaos. Imoko never abandons her sister, even though she hates her living conditions and habits.

YOUNGER SISTER

Name: IMOKO SATŌ Age: 18 years old Height: 158 cm Race: Cat girl (Nekomusume)

APPEARANCE

Face: A delicate, rounded oval face with a slightly pointed chin, soft cheeks, and an understated nose. Her mouth usually rests in a neutral, slightly serious expression.

Hair: Silky, chin-length silver-white hair. Her bangs are swept to the side, with an asymmetrical lock held in place by a small, tilted turquoise-blue hair clip on the left.

Ears and Tail: Two large, triangular cat ears sit on top of her head, covered in silvery-white fur with pale pink interiors and small white tufts. Her long, slender tail matches her coat and sways gently as she moves.

Eyes: Large, rounded almond-shaped eyes with reddish-brown irises and sharp, vertical pupils. Her light-gray eyebrows are thin, short, and slightly arched close to her eyes.

Body: Slender and petite build, with narrow shoulders, a graceful neck, and an upright, tidy posture.

Skin: Fair, smooth, human-like skin with no body fur.

Clothing: She is usually seen wearing her immaculate school uniform: a dark charcoal double-breasted blazer with four gold buttons over a white shirt, a large dark-red bow tie, a light-gray pleated skirt, dark knee-high socks, and loafers. Casually, she wears simple, clean outfits such as pastel cardigans over white blouses.

PERSONALITY

Focused, responsible, and composed, Imoko provides a strong contrast to Yaniko's lifestyle. Although affectionate and extremely patient, she has a dry, sarcastic sense of humor when dealing with absurd situations. She is a dedicated high school student and still lives at the family home with her parents.

LANDLORD

Name: ŌTANI ŌYA Age: 45 years old

Naturally patient and considerate, Ōtani is bald and physically imposing. His patience is constantly pushed to its limits by Yaniko's lifestyle.

Having grown up with an abusive father who was a compulsive smoker, he has severe and persistent trauma triggered by the smell of cigarettes. Despite his exhaustion, he continues trying to treat Yaniko fairly, making him one of the main unwilling victims of her everyday chaos.

WORLD

The story takes place in a modern society where humans and cat people (nekomimi) coexist seamlessly.

Nekomimi are neither mystical beings nor treated as anomalies, but rather as fully integrated citizens who live ordinary, everyday lives.
