And they were seen as symbols of luck in some areas.

Jorōgumo (絡新婦) are a demi-human species of "spider-woman" originating from Japanese mythology. According to folklore, the species are said to be spiders that can change their appearances into that of beautiful women due to gaining magical powers after turning 400 years old.

Depicted as being skilled at entrapping their prey, Jorōgumo possess many of the same traits as an Arachne; such as possessing six eyes, a light exoskeleton and the ability to produced webs, however, while an Arachne has the upper body of a human and the full lower body of a spider, a Jorōgumo possesses a fully humanoid body with a spider abdomen extending from the base of their spine but no spider prosoma. Also, in addition to their humanoid arms being covered in an exoskeleton, they have six fully dexterous "spider legs" attached to their upper back which they can hide beneath their clothing should they choose.

Kuruwa and Komachi are Jorōgumo's.

Kamaitachi

Prevalent in Japanese mythology, the species inhabits the inland mountain ranges of Japan (most notably Yamanashi, Nagano and Niigata) and are said to be able to "ride the mountain winds" in small tornadoes at such a speed that they are invisible to the human eye.

While within these tornadoes, Kamaitachi are said to attack humans by rushing them and slashing them with their sickle blades as they fly past.

Koro-pok-guru
Koro-pok-guru (コロポックル Koropokkuru) are a race of small people in folklore of the Ainu people of the northern Japanese islands. The Ainu believe that the koro-pok-guru were the people who lived in the Ainu's land before the Ainu themselves lived there. They were short of stature, agile, and skilled at fishing. They lived in pits in the ground with roofs made from butterbur leaves.

Long ago, the koro-pok-guru were on good terms with the Ainu, and would send them deer, fish, and other game and exchange goods with them. The little people hated to be seen, however, so they would stealthily make their deliveries under cover of night.

Unfortunately, one day, a young Ainu man decided he wanted to see a koro-pok-guru for himself, so he waited in ambush by the window where their gifts were usually left. When a koro-pok-guru came to place something there, the young man grabbed it by the hand and dragged it inside. It turned out to be a beautiful koro-pok-guru woman, who was so enraged at the young man's rudeness that her people have not been seen since.

Shinotcha is a Koro-pok-guru.

Kyubi no Kitsune
Kyubi no Kitsune (lit. Nine-tailed Foxes) are a pseudohuman race that appear in Japanese folklore as intelligent beings that possess magical abilities to shape shift. A variation of the Werefox species, while some folktales speak of kitsune of wildly different moralities employing this ability to trick others, other stories portray them as faithful guardians, friends, lovers, and wives. It is unknown if male Kitsune exist (as Kitsune can use both genders in their shapeshifting abilities) or if they are a single gendered race.

It is said that the more tails a kitsune has (they may have as many as nine) the older, wiser, and more powerful they are. Because of their potential power and influence, some people make offerings to them as deities.

Many Shinto Shrines posses statues of foxes as homages to Kitsune and the fox god. One kitsune, Ils Nineta, works at a Shinto shrine as a shrine maiden. Another kitsune, Youko, is an exchange student in the cultural exchange program.

Oni


Oni are a humanoid subspecies of Ogre that appear in Japanese folklore as a type of devil or ogre.

Aside from their colorful skin ranging from red to blue, Oni are no different from standard Ogres. Standing only two meters tall, they are slightly smaller than Ogres, making them the smallest of the Ogre subspecies. Though they are still larger than humans. Red Oni are thought to be crybabies and Blue Oni are considered self-sacrificing, but it is unclear whether or not there is any truth to these claims. It is customary for Oni to dress in tiger-striped clothes.

Kinu is an Oni working as an agent in the Talio private security firm.

Otter
Otter ("kawauso" (獺、川獺)) are a pseudeo-human liminal species from Japan that resemble river otters. Jovial and friendly shapeshifting beings, Otters mostly take on human form to play tricks and buy booze. Like their animal cousins, Otters prefer to stay near brooks, streams, seaside and rivers.

Araya is a Otter.

Rokurokubi
The Rokurokubi (ろくろ首, 轆轤首) is a type of Japanese yōkai (apparition). They look almost completely like humans, with one major difference. There are two types of Rokurokubi: one whose necks stretch, and one whose heads come off and fly around freely (nukekubi). The Rokurokubi appear in classical kaidan (spirit tales) and in yōkai works. It has been suggested, however, that the idea of rokurokubi may have been created purely for entertainment purposes rather than originating from any folk beliefs or legends.

Nana is a Rokurokubi.

Tengu
Tengu are a demihuman liminal species with black bird-like wings, elfin ears and the avian characteristics of crows.

Considered a mythical creature in Japan, they were historically thought to be troublesome demons but are now respected as highly skilled swordsmen and protectors of sacred forests and mountains.

Shizuka is a Tengu.

Werefox


Werefoxes are a pseudohuman species of beings who are spoken in myth of possessing the ability to shapeshift between the form of a human and the form of a fox.

Also known in Japan as belonging to the "Yokai" subspecies group, for some reason, many werefoxes take up positions as miko shrine maidens. A variation of this subspecies possess nine tails and are called Kitsune; these individuals are said to possess rudimentary transformation powers.

Yatagarasu
A Yatagarasu (八咫烏) is a demihuman liminal species very similar in appearance to Harpies. Possessing crow-like traits, Yatagarasu appear prominently in Japanese mythology as supernatural guides and symbols of divine rebirth and rejuvenation. Known to be the guide of the 1st Japanese Emperor Jimmu when he conquers all of Japan.

Omnivorous, Yatagarasu prefer habitats that have sunlight and demonstrate the same "air-headed" behavior as Harpies. As such, not much is known at precisely how closely related the Harpy race are to the Yatagarasu.

Misaki is a Yatagarasu.

Yuki-onna
A Yuki-onna (雪女) is a pseudohuman that appears in Japanese folklore as a snow spirit of inhuman beauty that appears before travelers trapped in snowstorms with the purpose of killing them.

While the Yuki-onna race is not inherently malevolent, their stoic demeanor and their natural environment being hazardous to humans, may have given rise to myths that they intentionally cause deaths.

While possessing elemental control over ice and snow, Yuki-onna can not live in high temperate environments without assistance.

Yuki and Yukio are Yuki-onna.

Zashiki Warashi
Zashiki Warashi (座敷童 or 座敷童子) are spiritual beings that reside in a house or settlement.

They have the ability to either bring good luck or misfortune upon a person or a household.

Sasami is a Zashiki Warashi.
