AR Quirks

**Altera Rationem Quirks** (lit. Other Dimension), or as they are called more often **AR Quirks**, are special types of quirks that in one way or another have some "otherworldly" aspect to them. These aspects can vary from said quirk turning it's user into a yokai to it straight out originating from another dimension or being somehow connected to one.

## Extra-Dimensional Quirks

### Transformation

* **Bakeneko** - User can transform into a Bakeneko (changed cat), a cat yōkai with supernatural abilities. While their true form is an unusually large cat with forked or doubled tail and ability to walk upright, they're able to change their shape. The one who possesses this quirk currently is Ryuko Koigakubo.

* **Gashadokuro** - A transformation quirk. User can transform into a Gashadokuro (lit. "starving skeleton", also known as Odokuro), a giant skeleton that is fifteen times taller than an average person. The one who possesses this quirk currently is Riko Shinso.
* **Kitsune** - A transformation quirk. User can transform into a Kitsune (lit. "fox"), a fox-spirit, who usually gain their powers by living long and keep growing stronger as they age: The more tails a kitsune has – they may have as many as nine – the older, wiser, and more powerful it is. Stories depict them as intelligent beings and as possessing magical abilities that increase with their age and wisdom. Their powers include illusions, shapeshifting (particularly to human form), possession, and especially the ability to use fox-fire.
* **Mizuchi** - A transformation quirk. User can transform into a Mizuchi (master of the water), a Japanese dragon or legendary serpent-like creature, which is aquatic or somehow related to water, possibly a water deity.

* **Tsuchinoko** - A transformation quirk. User can transform into a Tsuchinoko. In Japanese folklore, the tsuchinoko (ツチノコ or 槌の子), literally translating to "child of hammer" or "child of dirt", is a snake-like being.
* **Ushi-Oni** - User can transform into an Ushi-Oni, a vaguely defined creature of a variety of monsters which resemble bovines. The one who possesses this quirk currently is Ayanami Eit.

### Mutant

* **Arachne** - A mutant quirk. User is an arachne, a centaur-esque creature that has the upper body of a human and the lower body of a spider, although their upper-body may have spider-like features such as multiple eyes. The one who possesses this quirk currently is Enko Eit.

* **Jorōgumo** - A mutant quirk. User is a Jorōgumo (lit. binding bride), a spider-yokai that can change its appearance into that of a seductive woman. The one who possesses this quirk currently is Aome Eit.
* **Moon Rabbit** - User has the abilities of a Moon Rabbit,  a mythical figure who lives on the Moon in Far Eastern folklore, based on pareidolia interpretations that identify the dark markings on the near side of the Moon as a rabbit or hare. The one who possesses this quirk currently is Reisen Yuzuki Inaba.
* **Tsuchigumo** - User is able to use the abilities of a Tsuchigumo; a yōkai that appeared to people as having faces of an oni, a body of a tiger, arms and legs of a spider, and wore giant outfits. The one who possesses this quirk currently is Kumo Ojisa.
* **Wraith** - A mutant quirk. User is a wraith, an incorporeal evil spirit from the netherworld - distinct from demons - that drains the life energy of mortals in order to sustain their existence and may be able to steal souls as well.
* **Yuki-Onna** - A mutant quirk. User is a Yuki-onna (snow woman), a yokai who is either the ghost of someone who perished in the snow or a personification of winter and snow.

### Unknown

* **Zombie** - A quirk that activates upon user's death. User, no matter what, 'survives' their death. After this, they slowly started to gain properties of a zombie. The ones who possess this quirk currently are Rina Fushi and her direct family.

## Extinction Quirks

Deemed a subtype of AR Quirks, Extinction Quirks evoke exaggerated and modified versions of extinct species, most commonly dinosaurs. Many of them seem to be along the lines of a mutant-transformation hybrid: The user has some abilities without needing to "evolve" into better forms. For simplicities sake, they will be referred to as Mutants.

Extinction Quirks have three "Forms": A passive form where the quirk is not fully active, yet bestows it's user with improvements to their normal human body, a more active "Aplos" form where the user further benefits from physical improvements, as well as gaining traits of the species their quirk is based on, and an exaggerated "Exa" form where certain aspects are exaggerated, with some even gaining new powers.

### Saurischia

#### Dromeosauridae

* **Utahraptor (ユタラプトル, Yutaraputoru):** User can invoke the abilities of a Utahraptor, gaining sharp claws to dig into prey, sharp teeth, improved speed, and so on. Exa form allows accelerated healing, venomous fangs, and enhanced speed, at the cost of hollower bones and lower impact tolerance, to promote a hit and run fighting style. The user also favors meats, and their abilities improve when eating raw meat, no matter the source.
	+ **Indoraptor (インドラプトル):** A subtype of the Utahraptor quirk. User can invoke the abilities of the Indoraptor, a fictional hybrid, gaining camouflage, enhanced sense of smell, and concussive roar, alongside the normal Utahraptor abilities. Exa form grants venomous claws, echolocation, and denser bones for defense, but takes away the accelerated healing and reduces overall speed. It also possesses an improved variant of it's normal concussive roar, being able to cause small tremors and turbulence. Overall a more aggressive sidegrade.

#### Abelisauridae

* **Carnotaurus (カルノタウルス, Karunotaurusu):** User can invoke the abilities of a Carnotaurus, gaining extreme musculature, short broad teeth for gripping, well developed leg muscle, enhanced smell, and two small horns on their head. These horns can serve to both dissipate shock and as weapons, being very well suited to stabbing and tearing flesh. Exa form allows the user to run at ridiculous speeds, akin to a raging bull, using their momentum to improve their attacks; the more they move, the deadlier they are. The teeth also secrete a venom that prevents coagulation of wounds, incidentally interfering with healing quirks, and the horns grow longer. In all three forms, the user can make use of powerful concussive roars to knock flyers out of the sky, create tremors, or throw people off their feet. The potency varies as the user progresses their evolution. Like all Extinction Quirk users, Carnotaurus improves by eating a similar diet to the origin dinosaur, in this case, meat.

#### Spinosauridae

* **Spinosaurus (スピノサウルス, Supinosaurusu):** User can invoke the abilities of a Spinosaurus, gaining conical teeth for gripping, enhanced dexterity, and claws for slashing, alongside aquatic adaptations such as echolocation, swimming, and danger sense. Exa form allows the user to modify their body temperature, allowing them to create an icy or fiery armor, and blast scalding water from their mouths. The user favors fish meats, and improve upon eating it raw.

## Unidentified Quirks

* **Descensum** - User can separate their spirit from the body by entering a trance, gaining access of travel the Astral Plane.

* **Mind's Eye** - User has The Mind's Eye (also known as the inner eye or third eye) a mystical, esoteric and mental concept referring to a speculative invisible eye which provides perception beyond ordinary sight.

* **Uni-Me** - Despite a pretty cute sounding name, the quirk itself is pretty serious in a way. User of this quirk basically have a whole universe inside their body that exists and develops as long as user lives.

* **Zodiac Signs** - User is able to have the powers of zodiac signs. Zodiac abilities are at their strongest during the months that they are active; their designated months. The one who possesses this quirk currently is Zodiac.
