aka: Inugami

Youkainote  are a widely-varied collection of various supernatural creatures that pop up in Shinto religion. They have a lot in common with The Fair Folk. Some youkai are good, others are evil, and many are different. Some are mischievous, others avoid humans entirely. Shinto is an animist religion, and youkai are often associated with natural features such as forests and mountains. This word is often translated as "demon" in Western translations, but since that term is generally associated with pure evil, that does not adequately describe the creatures in question — they are more like The Fair Folk, spanning the entire moral range between good, mischievous, neutral, and actually evil. The closest true Western equivalent is probably that of the ancient Roman genii or spirits.

Supernatural creatures drawn from Western sources often turn out to seem more like youkai in Japanese works. For instance, vampires.note  In the West you've got Nosferatu — a grotesque, undead monster who burns in sunlight and murders to preserve his hideous unlife. In Japan you've got exceptionally cute Fanservice protagonist Moka Akashiya, who is not undead, harbors no ill-will towards the sun, and drinks tiny amounts of blood that leave her "victim" light-headed at worst, but who has a Superpowered Evil Side who can (and will if you look at her the wrong way) kick your ass thoroughly.

Henge, a subset of youkai, are magical animals with Shapeshifting powers and human intelligence. They often assume human form and get into all kinds of mischief. Kinds of henge include Kitsune, Tanuki, and Nekomata.

Obake is another Japanese word that can indicate some type of monster. Derived from the word for “to change”, it generally covers the subset of youkai that includes shapeshifting animals (hence the terms bake-gitsune, bake-neko, etc.) as well as Animate Inanimate Objects. Confusingly, however, the word obake can also be used to refer to ghosts, also known as yuurei. See Stringy-Haired Ghost Girl for more information.

Ayakashi is a word which is roughly synonymous with "youkai" in current day usage, though traditionally it referred to a ghost that appears at sea during a shipwreck.

Many types of youkai were codified during the Edo period in the works of Toriyama Sekien. The genre of manga that deals with Youkai was founded by Shigeru Mizuki (1922—2015), who was obsessed with Youkai ever since he was a child. The Trope Codifier of modern youkai manga is his ever-popular GeGeGe no Kitaro that has received an anime adaption at least once a decade since it was written.

The list presented below is by no means complete. Many types of Youkai are exceedingly rare to find in modern media and so are not included. On the other hand, some have garnered enough examples to warrant their own pages.

Youkai with their own pages:
  • Hitodama
    Wispy lights that hover around ghosts and possessed people.

    A "river goblin" resembling a cross between a monkey and a turtle.

    Mountain-dwelling humanoids which either have long noses or resemble crows.
  • Yuki-onna
    A pale snow spirit lady.
  • Zashiki-warashi
    A childlike spirit that should be cared for to keep the one's house in good fortune.

Nekomata: A seemingly ordinary cat that develops magical nature through long life. It looks like an ordinary house cat except for the tail, which splits into two at half-length. While much smarter than it used to be, a nekomata remains just as whimsical, which may be dangerous with its new-found powers of illusion and necromancy. It's said a cat will become a nekomata after turning 100 years old, where upon its tail splits, it starts using human speech, somehow gains transformation powers, a greater intelligence, and other odd abilities. The name is often used and confused for catgirls. May be a Mega Neko.

A more general term for cat youkai is bakeneko, but almost all modern depictions of bakeneko will at least allude to the nekomata's signature split tail.

The Kasha, a mysterious grave-robbing youkai, is usually depicted as a nekomata Wreathed in Flames (specifically Hellfire).

     Nekomata Examples 
  • The two-tailed demon-beast in Naruto is a two-tailed cat.
  • Espeon and Meowstic in Pokémon are based off of this legend.
  • Chen and Orin from the Touhou Project. Orin, though, is a Kasha, a different type of youkai cat.
  • Axis Powers Hetalia fanfics Hakkōna and Kaitō Kokoro: Kiku is basically a Henge version of a nekomata known within both stories as a nekomataneko with the "nekomata" referencing the nekomata characteristics and the "neko" referencing the base human form with cat features.
  • Found in the Disgaea series (and are used in quick leveling tricks in BOTH the first and second ones). They are more Cat Girls, however. Capable of producing offspring with humans, as Rutile is half nekomata.
  • Natsuki, the Cat Girl protagonist of Hyper Police is revealed to be a nekomata in a moment of anger (her tail splits in two)
  • Tora of Ushio and Tora is named for his tiger-like appearance.
  • Kirara in InuYasha takes the form of a two-tailed kitten that can transform into a massive feline beast.
  • A monster type in Wild ARMs 2.
  • A common demon/Persona in the Shin Megami Tensei franchise.
  • One of the forms of the thing inside Touko's briefcase in Kara no Kyoukai.
  • Jubei and his daughter Kokonoe (a Cat Girl version of this) in BlazBlue. Appropriately, the latter does bring people back from the dead, although since magic is commonplace in that world she uses science to keep the mysterious powers theme. Iron Tager is the result.
    • The character Hakumen contemptuously calls them both "bakeneko" (monster/ghost cat), which in Japanese mythology is a general term for any cat Youkai. The video games translated this word as "Grimalkin" in an attempt at a Cultural Translation (which failed, since "grimalkin" is about as obscure as "bakeneko" to an American audience). Official subtitles for BlazBlue: Alter Memory use "Goblin Cat" instead (which is more accurate and conveys Hakumen's insulting tone).
  • In Mokke, one episode centers around a nekomata.
  • The X-Antibody version of Tailmon from Digimon is two-tailed.
  • One of the protagonists of Omamori Himari is a shapeshifting cat.

  • One episode of Kamichu! has a cat named Tyler who is leader of a "city of the cats" where all cats can walk upright and speak. Later, he is explicitly revealed to be a nekomata while tag-team wrestling.
  • Compared to other werecats in the Monster Girl Encyclopedia, the Nekomatas are rather tame and even give up on a man should he refuse her advance. They are still monsters though, and will eventually assault their prey to take his spirit energy. Unlike in the myth, Nekomata in this series are this way since birth. And since this world is filled with Cute Monster Girls, her forms are inverted, with the human form being the true one.
  • Cat God: Mayu and Sasana as well as their family are cat gods.
  • Matamune from Shaman King.
  • Alice's Adventures in Wonderland: The Cheshire cat may or may not be 100 or so years old, and he clearly doesn't have two tails, but he's otherwise a surprisingly close Western analogue to the nekomata. This is almost certainly a case of Strange Minds Think Alike, since it's unlikely Lewis Carroll would have heard of the Nekomata.
  • The mother of one of the main characters of Eight Million Gods is one.
  • A nekomata was a Monster of the Week in Shuriken Sentai Ninninger.
  • Koneko and her sister Kuroka in High School DxD
  • Miike, the protagonist of the Muramasa: Rebirth DLC "Fishy Tales of the Nekomata", is a nekomata who can transform into a two-tailed cat, a Cat Girl, a gigantic, monstrous two-tailed cat, and a floating head made up of cats.
  • The Series Mascot Jibanyan and most of the other cat Yo-Kai in Yo-kai Watch are cat youkai with two flame-tipped tails.
  • Saint Purrtrick from Neko Atsume is actually one of these, hence his two tails and "Ethereal" description. His Japanese name is even "Nekomata-san".
  • Super Sentai:

Tsukumogami: Inanimate objects that come to life after a hundred years. These can range from weapons to clothes to umbrellas. Well-known traditional examples include karakasa (paper umbrellas), ittan-momen (a floating strip of cotton cloth), biwa-bokuboku and koto-furunushi (stringed musical instruments) and burabura (lanterns). Strangely, they avoid electrical energy in common folklore from the 1940s and it is said that no modern object could ever become a Tsukumogami.

     Tsukumogami Examples 
  • In Love Hina, there is the Tsukumogami called "Moe", a near life-sized doll/puppet who comes to life about halfway through the series, disappears after spending some time with Keitaro, and reappears in the sequel OVA Love Hina Again.
  • Asagiri no Miko has two Tsukumogami among its characters.
  • Ichimoku Ren from Hell Girl is a Tsukumogami; specifically, he is the spirit of a sword. He was given a human form by Enma Ai, so he could better work for her.
  • Omamori Himari features as one of its protagonists a Tsukumogami based in an English teacup.
  • The Luggage from Discworld acts a lot like a Tsukumogami, and even comes from the Asian Fantasy Counterpart Culture, though it's actually made of "Sapient Pearwood".
  • Bob from Bob in a Bottle disguises himself as one, sometimes.
  • A variation of Tsukumogami, known as "The Animated", are the primary enemies in the Gaia Online MMO: zOMG!. Players can encounter animated Cotton Balls, Garlic Cloves, Purses, and even imperialistic Lawn Gnomes. Other enemies (including other youkai) exist as well.
  • Karakasa-kozō (umbrella) and Chōchin-obake (lantern) in Onmyōji
  • Several Pokémon appear to be based on Tsukumogami; unusually, some of these are modern objects, and indeed Electric-types. These include Magnemite (magnets), Voltorb (Poké Ball), Gardevoir (possibly anesama ningyou, a style of paper doll), Shedinja (the discarded exoskeleton of a Nincada after it evolves), Nosepass (Moai statue), Baltoy (shakokidogu), Shuppet (Teru Teru Bozu, a Japanese paper doll resembling a ghost), Banette (Voodoo doll), Bronzor (a bronze mirror), Bronzong (a bronze bell), Rotom's forms (refrigerator, lawnmower, oven, fan, washing machine), the Klink line (gears), Darumaka and Darmanitan (Daruma statues), Trubbish and Garbodor (garbage bags), Litwick (candle), Lampent (lantern), Chandelure (chandelier), the Vanillite line (ice cream cones), the Honedge line (swords) and Klefki (keychain). Though one would wonder how a candle or an ice cream cone would last the required hundred years without melting long before them.

  • There's a one volume manga called Tsukumo Happy Soul that involves Tsukumogami. While some are fairly normal, the main character's Tsukumogami is a pink vibrator she inherited from her mom that can turn into a boy. It is a bit ecchi, but it ran in a shonen magazine so it's more gag ecchi.
  • The Anthology Bordertown contains the short story "Demon" which has a Tsukumogami in the form of a teapot.
  • This can be the only explanation for a good half of the monstrosities strewn throughout Steve Moraff's Dungeons of the Unforgiven.

  • In the Izuna games, not only are some of the standard Tsukumogami found as enemies, you can actually make your own! The more you use a weapon, the more its "LUV" stat increases. When it hits 100, you can burn in a Tsukumo talisman to turn the weapon itself into a talisman; anything you stick it on will gain that weapon's special abilities. (It only works on weapons, not armour.) Make enough of these and you can get all the best powers in the game on a single claw.
  • GeGeGe no Kitaro has an ittan-momen whom Kitaro and his friends often ride on. It is weakened when it gets wet.

To drive the point home, their creator's name is Soichi Tsugumo.
  • Ushio and Tora has a killer marionette Youkai who needs hearts from young women to charge its mechanism. Later on the author shows a rare example of "modern" Tsukumogami with Ikkaku, a swordfish-like, speed-eating demon born from a motorbike and forcibly possessing people to make it drive faster and faster.
  • In the fanfic Kamikakushi, we have three. Botan, a boroboroton (futon-Tsukumogami), Churippu, an ichiren-bozu (prayer-bead-Tsukumogami) and Higanbana, koto-furunushi (koto-Tsukumogami).
  • Many Tsukumogami Monsters of the Week in Super Sentai.

Baku: A relatively benign example, being a creature with an elephant-like head that eats bad dreams. In modern Japanese the word baku can also refer to tapirs - when introduced to Japan, they bore such an uncanny resemblance to the mythological baku that they were assumed to be the same thing, and heavily influenced its later depictions. No relation to the capital of Azerbaijan.

Kamaitachi: Weasel-like creatures that attack in trios: the first one knocks down a traveler with a gust of wind, the second cuts the traveler with its sickle-like claws, and the third applies an ointment that stops the bleeding, leaving the victim with bloodless but inexplicably large and painful wounds. They're essentially the personification of the pain felt during a bitterly cold wind.

    Kamaitachi Examples 
  • Naruto: Temari, a special technique that involves summoning a kamaitachi. She is the wind user, while the Kamaitachi does the cutting. The only time it was used, the opponent was too dead to notice if the bleeding had stopped.

Makoto inadvertently took the latter as a pet, and, as the elder ones tried to find it, they brought catastrophe to the town —nearly killing Nube by slicing him in half until Makoto finally released the younger kamaitachi and it healed the teacher with its balm.
  • Digimon World 3 Kyuukimon (not to be confused with the aforementioned Kyuubimon) and Reppamon of Digimon.

  • Kamaitachi-style enemies appear in Namco × Capcom, and subsequently the Endless Frontier and Project X Zone games.
  • Super Sentai:

Tsuchinoko: A snake-like creature with a wide/fat body. It is mostly harmless to most people, unless awoken from its sleep as its venom can fell a man instantly. Seems to have developed from sightings of snakes that managed to snare a particularly large meal.

     Tsuchinoko Examples 
  • In Kemono Friends one of the Friends is a tsuchinoko. Appropriately, she's shy and likes to hang out in secluded areas.

  • In Touhou canon, specifically Strange and Bright Nature Deity, Marisa adopted a rather cute tsuchinoko as a pet after chasing it out of a fairy's house.
  • One of Yo Kai Watch's Ensemble Darkhorses is a literal Tsuchinoko, named "Noko" in the English version. There's also a variant called Tsuchinoko Panda (named "Pandanoko" in English), who has a panda's black and white coloration.

Nurikabe: A monster that takes the form of an animate section of wall. It has the power to turn invisible, and likes to use this power to impede travelers. Interesting enough, its common depiction of being an animated wall is somewhat of a modern representation. Originally during the Edo period, one of its early depictions was that of a three-eyed grotesque vaguely dog-like creature. Over time, its depiction changed to a literal wall with limbs and very vague features.

     Nurikabe Examples 
  • It's the name of a type of paper-and-pen puzzle. See the Wikipedia article for more details.
  • In Ōkami, there’s a family of nurikabe that go by the name "Blockhead." They claim to be "the only one", though.

Rokurokubi and Nukekubi: These two creatures are Humanoid monsters; the Rokurokubi are human by day but have extremely elastic necks during the night, while nukekubi can detach their heads from their necks and float away in search of human flesh.

     Rokurokubi and Nukekubi Examples 
  • Hellboy story "Heads" has him accidentally running across a household of Nukekubi. Needless to say, he hits them and pokes fun at them.

She's unable to control this state at first, and honestly believes that Nube, as the resident exorcist, will kill her because she's become a youkai, but he simply shows her how to control this new side of herself and the ability to extend her neck (sometimes across town) becomes another aspect of her personality... one that she uses incessantly to play pranks, annoy others, and, on at least one occasion, save the lives of herself and her friends.
  • The Fighting Fantasy gamebook Sword Of The Samurai had the protagonist visit an entire village of nukekubi, though the book mistakenly referred to them as rokorokubi.

  • A Rokurokubi married to a Kappa appeared in as a Monster of the Week in the first two episodes of Ninja Sentai Kakuranger.

Tsuchigumo and Jorougumo: These spiders are monstrous in size (as big or bigger than a man) that can take human form to seduce travelers. Jorougumo uses a lure to attract travelers to feed her offspring, and often has the power to allure men with a song. Others act as a Shapeshifting Lover. Tsuchigumo can also use illusions to keep his webs hidden and make people ill in order to feed on them.

The okuri-inu and okuri-okami tend more towards Noble Wolf, following travellers and protecting them from harm. However, they have a tendency to attack people who mistreat or offend them... or sometimes just those who show too much weakness; as a result, "okuri-okami" has become an idiom referring to stalkers and Wolves in Sheep's Clothing.

     Inugami and Okami Examples 
  • InuYasha:
    • Inuyasha is a half dog-youkai. Inuyasha's father, stepmother, and half - brother Sesshoumaru are full dog-youkai. However, the story distinguishes between what Inuyasha's family is and "inugami" when villagers mistake Inuyasha for one and the gang are confused the mistake could have happened.

Nuppeppo: A fleshy blob creature that lumbers around in deserted places, mainly temples and graveyards. Has a smell comparable to that of rotting flesh, leading some to believe they are made of corpses. In spite of this, Nuppeppo are generally peaceful creatures.

    Nuppeppo Examples 
  • The Gulpin line from Pokémon resemble this creature, being voracious stomachs that emit repulsive gases while digesting their food.
  • Yume Nikki has two examples:

Gashadokuro: A giant skeleton, it is born from the bodies of those who died without proper burial (usually from plague, famine, or war). They stand 15 times taller than a normal person and come out after midnight to drink the blood of whoever they can snatch up. Their approach is heralded by the rattling of bones (hence the name, which means "rattling skull" in Japanese), and their only weakness is a purifying ward. They are otherwise indestructible and sometimes can turn invisible.

  • Yo-kai Watch has several bosses based on this youkai. For example, Gusty Bones is a huge skeleton who lurks around the local elementary school.
  • Gashadokuro is The Dragon to his father and Big Bad Daimaou in Ninja Sentai Kakuranger. Fans of Power Rangers, however, will probably recognize him better as Rita Repulsa's boneheaded brother Rito Revolto.

  • Kind of a rarity in Cuphead, as all of the ghosts inhabiting the Phantom Express are subtly based on different types of youkai. The Blind Specter is based on tenome, an eyeless old man with eyeballs on his hands; T-bone is based on gashadokuro, a giant skeleton; the Blaze Brothers appear to be based on wanyuudou, flaming oxcart wheels with screaming faces; and the Head of the Train is based on oboroguruma, oxcarts with faces found on roads late at night. Maybe; what Japanese spooks are doing in a game based on American cartoons is a mystery.

It's also the general favorite among Mission-Runners, due to its high amount of Firepower.

  • Hakaba Kitaro
  • Harukanaru Toki no Naka de has these creatures among its mook-type villains (somewhat confusingly, they fall under the collective term onryou, "vengeful spirits", which normally refers to ghosts). In the manga/anime adaptations, some of these get more prominent roles, like the last Nue and the Tengu of the Northern Mountains, but otherwise the youkai-like monsters in general are of little importance to the plot.
  • Hell Girl also features a Hone-onna, or "Bone Woman", a type of vampiric creature which disguises itself as a beautiful mortal woman to lure men away to feed upon their life force.
  • Hell Teacher Nube. Between these and Obake, it's practically the whole point. If they're not listed among the specific examples above, it's because they're minor characters, but trust us, these (and more) show up.

  • Miss Hokusai, despite being a relatively realistic slice-of-life anime movie about Hokusai's daughter, has several youkai: A famous courtesan is a rokurokubi — her "spirit" stretches instead of her physical neck and while only a few people can see it everyone sees it pressing against the courtesan's mosquito netting. Ghost lights appear in front of a "haunted" painting of Hell and a giant ox demon threatens to show up at the house where the painting is. The painting is "haunted" because "Miss Hokusai" forgot to show the ghosts in Hell being redeemed by Buddha (which was kind of the whole point of the painting's commission in the first place, oops). Hokusai adds the Buddha and the haunting stops.

  • Pocky And Rocky: Nearly every enemy encountered is some form of youkai, and several of the partners throughout the series are as well.
  • Pokémon has a lot of creatures based on youkai. An example is Mawile, who is based on the futakuchi-onna, a woman with a monstrous, voracious mouth growing out of the back of her head and hair that functions like tentacles. Mawile gains a Mega Evolution in Generation VI, which gives it two mouths on the back of its head. It can even be said that all Pokemon take on the same roles that youkai supposedly play in the real world, as both take on the roles of animals and nature spirits while also being combination of malicious and scary yet friendly and endearing when befriended.
  • In Pom Poko, the tanuki prove capable of transforming into a wide variety of other youkai. Some actual kitsune make an appearance as well.
  • In the Pony POV Series, while the normal versions exist as species (with Kitsunes and Shisa being seen in Neighpon), this word is used to describe the Draconequi equivalent of angels.

  • Randy Cunningham: 9th Grade Ninja has really shown its work for a western cartoon when it comes to the actual Japanese mythological elements, right down to the inclusion of youkai.

  • Ranma ˝ frequently exploited Japanese folklore to provide their Monster of the Week.
  • Rosario + Vampire: There is a reason the school is called Youkai Academy (though monsters from many other cultures are largely present as well). The name of the school, however, is a Punny Name, since it uses a different set of kanji than the ones that designate the youkai.

    • Ninja Sentai Kakuranger: The enemies are ALL Youkai, nearly all of which have adapted in some way to the modern world. For example, there's a Nurikabe covered in graffiti, a Sand Woman dressed like a hooker, a chariot youkai who's now a taxicab and a gluttony spirit dressed like a fast-food jockey. Sometimes the behavior is very different from the traditional youkai they're based on, but that's usually excused with "long ago, they were like [insert mythological behavior here] but the modern ones are [insert a Monster of the Week-ish behavior here] instead!"
    • Samurai Sentai Shinkenger: The enemies are called ayakashi and are based on youkai, but following ayakashi's traditional meaning of "shipwreck ghost", most if not all of them have some kind of sea-creature theme along with their mythic one.
    • Shuriken Sentai Ninninger: Similar to Kakuranger, the enemies are modernized versions of youkai; this time done by bringing inanimate objects to life. For instance, a chainsaw is turned into a kamaitachi and a snowcone maker into a yuki-onna. They also bring in three classic Halloween monsters (Frankenstein's Monster, Dracula, and the Wolf Man) and classify them as "Western yokai".
  • Tactics, unsurprising since the show chronicles the adventures of a Japanese folklorist who practices Shinto and does exorcisms to make a little on the side.
  • Tale of Yashima: A web novel set during the Sengoku Era of Japan where several yokai feature as both main characters and villains.
  • Throne of Darkness, a Diablo-like Hack and Slash uses nearly only monsters of these origins.
  • Touhou Project: Almost every known character, apart from the four-and-a-half human protagonists, a couple ghosts, and a handful of goddesses, is some form of youkai. Whether or not fairies are youkai is also subject to interpretation, both in and out-universe.
  • Youkai or kaiju based on them have appeared as a Monster of the Week in many entries of the Ultra Series. Many are based on examples above, but others have no basis in folklore and are original creations of Tsuburaya Productions.
    • Woo from the original Ultraman is a yeti-like youkai manifests from the spirit of a deceased parent who seeks to continue to protect their child.
    • Ultraman 80 featured a few youkai, like Jihibikiran (a sumo boy who wrestles everyone he meets) and Idantenran (a marathon runner who transforms into a giant monster when enraged).
    • An episode of Ultraman Tiga featured a youkai named Obikoboushi (Obiko for short), a mischievous demon-like creature who thrives in darkness and disguises himself as a noodle vendor in order to scare people with his magically animated shadow.
    • Two episodes of Ultraman Cosmos deal with a gorilla-like youkai named Yamawarawa who likes to befriend children lost in the forest. In the latter episode, we also meet Yamawarawa's archenemy, the demon-like Mahagenom.
  • Urusei Yatsura, which, despite the nominal sci-fi setting, features many youkai both as Ancient Astronauts and as actual monsters.
  • Usagi Yojimbo has featured nearly every monster from Japanese tradition, from Oni to Kappas to Nues (chimera-like beasts) and an Obakeneko (vampire cat).
  • Ushio and Tora is all about fighting youkai until facing the strongest of them all, a god-like kitsune (born in India of all places).
  • Wagaya no Oinari-sama. has spirits like these, including an entire arc with oni.
  • ×××HOLiC features many types of youkai.
  • In Yes! Pretty Cure 5 GoGo! episode 27, "Rin-chan vs. Ōedo Yōkai!", Shibiretta takes the Cures and mascots back to the Edo period, where they encounter noppera-bō, rokurokubi, karakasa, oni and burabura.
  • Yo-kai Watch is a Mon series revolving around Yokai. The games and anime revolve around a boy named Nate using a mystical watch to perceive, communicate with, and summon Yokai to solve other people's (or other Yokai's) problems.
  • Yodanji is a mobile Rogue Like that features many of the yokai listed as character classes.
  • Youkai Monsters, a Japanese movie series.
  • Yozakura Quartet
  • Yu-Gi-Oh! has a number of cards based on youkai:
    • There is an archetype (cards which share part of their name and work very well with each other) called "Hermit Yokai". It seems to be mostly (if not entirely) made up of Kamaitachi.
    • Spirit Monsters are a type of card that return to your hand at the end of the turn, the majority of which are based on famous gods and monsters from Japanese myth.
    • In the Yu-Gi-Oh! GX manga, Bastion briefly uses a deck comprised of youkai that centers around bringing cards back from the graveyard.
  • YuYu Hakusho
  • Yuki Yuna Is a Hero features cutesy versions of traditional youkai as the characters' fairy partners. The title character is accompanied by a Gyuuki that takes the form of a tiny bull with stubby wings.
  • The Zashiki Warashi Of Intellectual Village revolves around youkai and humans making use of their power for various purposes. The eponymous Zashiki Warashi is a major character.
