Synopsis
Chiikawa is set in a civilized world inhabited by small animal-like creatures known as chiikawas, armor-wearing figures known as Yoroi-san (armor people), and various monsters and other creatures. The story follows the daily adventures of the titular protagonist, Chiikawa and their friends as they enjoy delicious food, pursue hobbies, and find joy in everyday life, while navigating the constant dangers of their world. To earn money, some of them take on jobs assigned by the Yoroi-san, including weeding and hunting, which can be fatal.
Production
The character of Chiikawa originated from a May 2017 tweet expressing Nagano's wish to escape modern life and become a simple creature that cries over its troubles, runs away from them, sleeps, and dances. Chiikawa, Hachiware, and Usagi were originally named Nitori, Ikeya, and Donki, respectively. The reason that Nagano chose Twitter was because of its immediacy and accessibility. By November 2020, Kodansha collected the comics into physical volumes, the first of which was published in February 2021.
A separate account was created in January 2020 and the manga began serialization. A book version was published by Kodansha on February 12, 2021. Prior to that, a one-shot story was published in the eleventh issue of Morning was released on February 10.
Characters
Chiikawa (ちいかわ; lit.'Something kind of small and cute')
Chiikawa is the titular protagonist of the franchise. They are small-sized, have rounded ears and a teardrop-shaped tail, resembling a mouse or hamster. Early on, Chiikawa was named as Nitori. Cowardly, timid, and having a tendency to cry, they live in a house won in the Muchauma Yogurt lottery. Unlike some other characters, their speech is unintelligible to the audience – mostly saying things such as "yada" and "iya" – both of which are childish ways of saying "no" in Japanese. They primarily express themselves through sounds and facial expressions, but it can be understood to the rest of the cast.
Chiikawa passed the fifth grade weeding exam after three attempts, which stands in stark contrast to another main character, Hachiware, who passed it on the first try.
Hachiware (ハチワレ; lit.'Eight-split' or 'Broken-helmet')
Hachiware, originally named Ikeya, is a friend of both Chiikawa and Usagi and lives in a cave. Their name and design are based on those of a bicolor cat, but they are not one. They are depicted as sociable, curious, and optimistic, as well as being kind-hearted and willing to help their friends, especially Chiikawa. Hachiware is also an avid photographer, and they like the Charumera brand of instant ramen. Hachiware lives in a cave. Like Chiikawa, Hachiware has the Level 5 Weed Pulling Certification.
Hachiware's name originates from the blue marking on its head, which resembles the kanji for 'eight' (八), hence 'eight-split' (八割れ). The character is known as 'little eight' (小八) in Greater China.
Usagi, originally named Donki, is a friend of both Chiikawa and Hachiware. Depicted as high-spirited, they occasionally act as a troublemaker, but support their friends when they are in trouble. Similar to Chiikawa, Usagi is unintelligible to the audience, making noises such as "ura" and "yaha", but can be understood to the other characters. Usagi's name and design is based on those of a rabbit, but "may or may not" be one. They are mainly known for being eccentric and a foodie. Usagi is also revealed to hold a Level 3 Weed Pulling Certification, which they show to Chiikawa and Hachiware after the pair take the Level 5 exam.
Momonga is a naughty and playful flying squirrel and diva. They are always focused on acting cute, begging for attention, and often throws tantrums in contrast with the others. Even during dangerous situations, they ask for food and rest. Momonga often "acts cute" in pursuit of their aims. Although they lack knowledge in social cues, they make an active effort to imitate other characters' cute actions, notably Chiikawa. They particularly often imitate Chiikawa's yawning and crying sounds. Moreover, despite being mostly depicted as doing things on their own, they start to hang out with Furuhonya in later chapters, albeit mostly for personal benefit. It is heavily implied that Dekatsuyo swapped bodies with Momonga with the help of a witch.
Kuri-manjū's character design is based on a honey badger and Kuri Manju, a Japanese confectionery bun made with chestnut fillings. They are always seen drinking alcohol, especially beer, and eating various foods, usually emitting a loud, exaggerated breath after taking a sip from their beverage.[bettersourceneeded] :Incidentally, in the region where they live, drinking alcohol is permitted only if the person carries a license that can be obtained by passing a difficult examination.
Rakko is a sea otter that excels in battle, and is top of the subjugation ranking. They have a cross-shaped scar above their right eye, don a white cape, and wield a double-edged broadsword with their face insignia on the hilt. Despite having a hard-boiled appearance, Rakko has some unmasculine aspects, such as: having a soft spot for desserts, and shuddering in agony during their first dip in a cold water bath. They also can drive, sometimes singing loudly to stave off drowsiness.
Shisa is a hard-working chiikawa critter with multiple occupations, most notably as an employee at the Ramen Restaurant Rou, and as apprentice of Ramen no Yoroi-san. They hold the "Super Part-Timer" certification, another qualification that is difficult to obtain. Shisa is also frequently seen with Kuri-Manjū, offering them food, or learning about liquor so they can obtain a drinking license. Their character design is based on the Ryukyuan cultural artifact of the same name. So sometimes, they use the Miyakoan language and reference local topics from Okinawa Prefecture.
Furuhonya is a kind and peaceful used-bookseller. They are a pink critter, roughly resembling a naked mole rat, wearing a crab claw-inspired headband, made by Pochette no Yoroi-san, and gifted by Momonga. Although initially a faceless mob character, Furuhonya had their design revealed after Momonga gifted said headband. Their official name is Furuhonya (古本屋), but author Nagano put the subtitle Kani (カニ; lit.'Crab') underneath the frame of their face reveal, earning the nickname Kani-chan (カニちゃん).
Kabutomushi (カブトムシ; lit.'Beetle')
Voiced by: Shiori Mutou (original form) and Kentaro Tone (Mimic form)
Kabutomushi, also known as Chiikabu, is a playful rhinoceros beetle-like creature that becomes Chiikawa's friend. It shows a cute appearance and personality towards the other critters, but in reality, Kabutomushi is a mimicking monster who lures in chiikawa critters to eat.
Anoko, originally known as Grey no Ko (グレーの子, Gurei no ko; lit.'The grey kid') is a wild and dangerous chimera that originally had the body of a chiikawa critter that worked alongside Chiikawa at a lemon-labeling factory. Though they recall memories of being a chiikawa critter, they don't seem to regret transforming into a chimera, as they are pleased to be significantly stronger than the chiikawa critters that come to hunt them down.
Dekatsuyo is a chimera that roughly resembles a furry spider. Despite being usually docile and timid, they show extreme aggression towards Momonga, for the two allegedly had their bodies forcibly swapped by an evil witch. Dekatsuyo hangs out with Anoko at times, but dreads the latter toying with/snacking on chiikawa critters.
Pochette no Yoroi-san (ポシェットの鎧さん; lit.'Body-Armor with Pochette')
One of the humanoid species that wears silver armor and carries a pink pouch that they crafted themself. They are kind-hearted (though they are scolded at times for said behavior towards the chiikawa critters), and often makes costumes for the main trio (Chiikawa, Hachiware, and Usagi) to try out. They are good friends with Rōdō no Yoroi-San and Ramen no Yoroi-san, the three often hanging out together.
Rōdō no Yoroi-san (労働の鎧さん; lit.'Body-Armor Labor')
A humanoid character wearing yellow armor that works at the Ramen Restaurant "Rou" (it is inspired by Ramen Jiro). Shisa apprentices under them as part of the Super Part-timer Program.
Pajama Parties (パジャマパーティーズ, Pajama Pātīzu)
Pajama Parties is a music unit that sings and dances whilst wearing different colored pajamas made by Pochette no Yoroi-san. The group consists of Midori, Pinku, Murasaki and Shiro. Their signature song is "Pajama Parties no Uta" (パジャマパーティーズのうた, Pajama Pātīzu no Uta; lit.'Pajama Parties' Song'). Before they perform in a music festival, Pinku, Murasaki, and Shiro were kidnapped by a giant, bird-like chimera, leaving them with scars on their faces and ears missing.
The creator, leader and songwriter of Pajama Parties. They have cow-like horns and tail and wears green pajamas, hence their handle. After their friends were abducted by the bird-like chimera, they asked the main trio to join Pajama Parties as substitute members.
A Pajama Parties member resembling a pig, and wearing pink pajamas, hence their handle. They lost their right ear and gained a giant cross-shaped scar on their face by the bird-like chimera.
A Pajama Parties member, like Chiikawa, resembling a mouse and/or hamster, and wearing purple pajamas, hence their handle. They lost their left ear by the bird-like chimera.
