Chainsmoker Cat World

Set in a modern-day world where cat-people, known as "beastfolk", co-exist with humans, the series follows the daily misadventures of Yaniko, a beastfolk who lives in a small apartment building in Nyagamihara (based on Sagamihara), Japan, and is addicted to smoking, regardless of the damage to her environment, her psyche, or her family. The series also features her interactions with her oddball neighbors, each with their respective issues, and their cranky human landlord who tolerates their antics.

Yaniko Sato- A freeter with a morbid addiction to cigarettes, but no financial literacy or everyday skills. Almost all money Yaniko receives goes towards buying new cigarettes, and when she cannot buy new packs, she often resorts to reusing spent cigarette butts or salvaging loose smokes off the street. Her need for nicotine often leads her into absurd and humiliating situations, and her attempts to quit never last long. Despite her self destructive habits and gross lifestyle, she has a bit of charm that keeps her friends and her younger sister from ever truly giving up on her. Has silver-green hair, ears, and a tail with black tips, paired with dull amber eyes.

Oya Otani- The landlord of the apartment building where most of the main cast lives. Despite his intimidating appearance and gruff demeanor, he is a caring man, though he is often the victim of his tenants' actions. He has a dog-like sex doll in private, and he often experiences erections due to certain things happening while he is around female beastfolks. Has a toned fat-set human man in his 40s with a completely bald head and a stocky build featuring a round midsection, and an intimidating "face of a thug" defined by thick, prominent eyebrows and eyes that are perpetually shrouded in shadow, giving him a perpetually stern and gruff expression; a tiny nose, and a small, downturned mouth. His minimalist outfit consists of a plain crew-neck grey t-shirt paired with dark charcoal trousers and simple open-toed black strap sandals.

Imoko Sato- Yaniko's younger sister who is a respected and responsible high school student. She often takes care of Yaniko's well-being despite her constant frustrations. Has Lavender hair, matching lavender cat ears and tail, paired with crimson eyes.

Yakuko Etsushimaru- A beastfolk who has looked up to Yaniko as her senior since her high school days. Among all the residents of the apartment, she is the one Yaniko hangs out with most often. She secretly uses harder drugs in her apartment, including marijuana, though she always vehemently claims to be sober. It is also implied that she is an ex-convict. Despite this, Yakuko is much more social and well-adjusted in her life outside of her drug use. Has Blonde-yellow hair and tail featuring dark black roots at the top, paired with golden-amber eyes.

Hameko Easygoing Anal Angel- Yakuko's high school classmate who is a gamer and runs a livestreaming channel, "Hame Channel". Born without a legal last name due to being a pure beastfolk, she decided to register "EasygoingAngel" (ゆるふわ＊天使, YurufuwaTenshi) as her last name. However, a city hall worker mistook the asterisk symbol for an anus, hence giving her a rather awkward last name. Hameko gets easily angered and flustered when things do not go her way, and has a tendency to urinate when stressed. Has Dark hair streaked with pink strands, and reddish-brown eyes.

Kaoruko Nishi- A calm cat-girl beastfolk with olive-gold hair and matching feline ears. A college student, fellow smoker and amateur comedian from the Kansai region who is one of the more put-together members of the apartment building. While passionate about making others laugh, she lacks genuine talent in comedic delivery and her attempts at humor often lead to awkward reactions.

Aruko Sakai- Kaoruko's roommate, a fellow college student who is sometimes mistaken as a elementary school student due to her short stature. She is an alcoholic, spending most of the day drinking and sleeping in her room, to the point of affecting her academic performance. She also often wanders off to distant places when she drinks outside her home. Has Auburn hair, auburn ears, and a fluffy auburn tail.

Saori Tatsuno- The only human resident in Oya's apartment building, as well as a fellow smoker. She works as a hentai manga artist under a pseudonym, though her manga does not sell well. Yaniko sometimes acts as her unofficial assistant.

Kazushi- The yakuza-esque editor-in-chief of Nyan Magazine, in which Saori's work is serialized.

Lani- The chief of Alpha Tribe, a local primordial beastfolk tribe that cultivates tobacco. She has two tails akin to that of a nekomata.

Nazuna Kujou- A homeless beastfolk who lives in a tent near a river. Claiming to be one with nature and often speaking in an aloof, philosophical manner, she is very sensitive and emotional in private. After her original tent is swept away by a flood, she squats in the yard of Oya's apartment building. It is later revealed that she actually comes from a wealthy industrialist family, but she ran away to seek freedom.

Shizue Sato- The widowed mother of Yaniko and Imoko. She herself is a chain smoker as well, though she manages to hide her habit from Imoko. Has Silver-grey hair, feline ears with pink interiors, and warm golden-yellow eyes.

Shunran Nishi- Kaoruko's younger brother who enjoys teasing her. Sporting stark white-silver hair and shark-like teeth. Has White-silver hair, white cat ears with pink interiors, and yellow eyes.
