Tsuki Uintā

Tsuki Uintā is part of a family that has a tradition in specializing in winter-based magic. Her family recognises her as the strongest mage in her family aside from Yoko. Tsuki is also the strongest general of the Hyakki Yagyō and a master at both Winter Magic and Ice-Make. This mastery over winter-based magic has given her the nickname "Winter Demon."

Appearance
Tsuki is a demon who has the appearance of a 19 or 20 year old woman. She has mostly blue hair with strips of black near at and the end of each strand of hair. On the right side of her long hair there is a wave-like pattern where it should be blue. She usually wears a long white kimono and white obi, a white scarf, white socks, and brown-strapped sandals. The sleeve length of the kimono is long enough to easily hand hands. Near the end of each sleeve and at the bottom of the kimono are greyish black snowflake shaped designs. They are believed to be the symbol of the Uintā family.

Tsuki's eyes is unusual in that around each pupil there is a single black ring. The eyes themselves are golden in color. However, for some odd reason her eyes turn blue when she is using Winter Magic or Ice-Make. It is currently unknown whether this trait provides any benefits during battle.

Personality
Tsuki is a kindhearted and thoughtful demon who, is very loyal to Nurarihyon. She hates people who insult Nurarihyon and one of the things she loves is having intellectual conversations. In general, she is nice to most people and has the habit of seeing the good side of people rather than focusing on the bad. This tendency causes her to be a very trusting and trustworthy person. However, Tsuki has another side to her, a side that mirrors her element of ice perfectly.

Itsuki
Tsuki has been shown to be very loyal and have great respect for the demon lord known as Itsuki. Her most known trait is her trust in Itsuki's judgement to the point that she would anything Itsuki says no matter how immoral or dangerous it is. However, since Itsuki would never ask Tsuki or any of the other demons following him to do something immoral or life-threatening, this trust that Tsuki has with him as never been tested to its limits. This fact about Itsuki is one of the main reasons she trusts him so much in the first place, if he does ever ask something like that Tsuki would know that Itsuki probably spent days thinking about and that this was his only option.

This is just the surface of her relationship with the demon lord and their relationship is a bit more complicated than that. When they are by themselves she talks to him as if she has a very deep friendship with him. Some demons in the guild suspect they may even have a romantic relationship, but as of right now this rumor is still unconfirmed. This deep friendship occasionally reveals itself to the public whenever Tsuki accidentally addresses the demon lord by his real name instead of Nurarihyon.

During battle their teamwork is flawless, suggesting that they have been through a lot together. This teamwork seems to be directly linked to Tsuki's ability to read Itsuki's emotions and her knowledge of what he likes to do during battle. It is said the only team that has better teamwork, then Tsuki Uintā and Itsuki is Otohime Dragonborn and Gyūki.

History
Like most members of her family, Tsuki was born and raised in the Antarctica. When Tsuki was born, her parents discovered that she was born with cryokinesis and since she was still a baby her powers would often get out of control. This was shown constantly as a baby because every time she was upset she would subconsciously create a mini ice storm around her.

As she got older, Tsuki's anger grew more dangerous. When she reached the age of four her temper tantrums stopped creating mini ice storms and started creating very sharp icicles that would pop out at random spots around her. Once when she was five, she created icicles so big that it stuck out in random places in the house. On that day her parents nearly died and they decided to quickly teach her Winter Magic and Ice-Make.

When her parents started teaching her Winter Magic and Ice-Make, they discovered that she was a natural at it. By the time she was seven years old, her skill level with Winter Magic and Ice-Make was on par with mages twice her age.

When she reached the age of seven, her father started teaching her Winter Fist and Teleportation Magic. However, her skill didn't come without a cost. Due to her talent, most of the demons outside of her immediate family family was scared of her.

Just like Tsuki, there was a boy who also was shunned, but for a different reason. He was shunned for his weakness to the cold. Tsuki and this boy quickly became friends. Tsuki would help him get used to the cold while the boy helped Tsuki blend in so she wouldn't be shunned as much.

Equipment
Frostbite is a small dagger with a blade that is a footlong. The blade of frostbite stays at a constant tempature of zero degrees fahrenheit. No one outside the Uintā family knows of the secert to keeping the blade at that tempature so it is assumed it is some kind of family heirloom. Senbon are foot long metal needles that Tsuki uses for assassination missions. These neddles are often used for medical purposes. However, in Tsuki's hands they is very deadly. It is unknown how many senbon she has because she uses Requip magic to summon them.

Winter Magic
Winter Magic is a very secretive type of magic that is practiced only among the Uintā Family. This magic allows the user to create and manipulate different aspects of winter. When mages think of Winter Magic they assume it is limited to hail, ice, snow, blizzards, etc. While mages of Winter Magic are able to create, produce, and manipulate it on both a small and large scale, they are not limited to only these things. Winter is associated with lot more than that. For example: darkness, hibernation, cold water, migration, sadness, loneliness, pain, sickness, and winter weather.

This means users of Winter Magic are able to put an opponent to sleep for long periods of time, manipulate darkness, force animal souls out of mages, inflict feelings of sadness or loneliness through touch, inflict sensations of pain though touch, manipulate the weather to create winter-like weather, and inflict sicknesses usually seen during the winter.
 * Ice Blade: Seven Slice Dance
 * Iced Shell
 * Breath of the Yuki-Onna: Breath of the Yuki-Onna is Tsuki's signature spell. This spell is very much like Roar of Darkness, it is said that Tsuki based this spell off of  Roar of Darkness. The user releases a large quantity of cold energy and expels it out of their mouth. Upon impact the foe will either be frozen in a block of ice or propelled back. The potential power of this spell is capable of pushing back Roar of Darkness.
 * Blizzard Breath: Blizzard Breath is a fast acting spell derived from Breath of the Yuki-Onna and Blizzard that is known as Tsuki's most used spell. It allows Tsuki to release a powerful blizzard from her mouth. Unlike its parent spells, this spell can be used for offensive, defensive, supplementary, and recreational uses. Tsuki is able to use this spell to freeze the floor beneath her in the same way Ice-Make: Floor can. She is also emit a concentrated blizzard beam from her mouth causing minor frostbite with any living thing it touches. Tsuki is able to redirect solid attacks by releasing the blizzard and manipulating it around the desired object, allowing her to move the object by simply turning her head. Occasionally Tsuki can use this spell to expel thousands of tiny pellets of dry ice instead of expelling a blizzard.
 * Hammer of Winter: The user coats their fist in cold energy and punches the foe with it. Upon impact the foe is propelled back and then becomes frozen in a block of ice. Similar to Roar of Winter, this spell was created by Tsuki and was based of a Dark Regulus spell. In this case, it was Hammer of Darkness.

 * Blast of Winter Wind: The user holds their hand in front of them and unleashes a blast of freezing wind.
 * Cold Flight: By flowing cold air under the user, the user gains the ability to fly with amazing maneuverability.
 * Fimbulwinter: Fimbulwinter is a spell that is somewhat similar to the spell, Terrain Effect: Cold Zone. Fimbulwinter is a very harsh and unforgiving Winter Magic spell that takes a lot of skill and magical power to perform. Fimbulwinter is a spell that allows the user to instantly freeze the landscape around them and cause the temperature to drop to negative five degrees. The secret behind this spell is the user thinly disputes their magic power over the desired area.
 * Cold Wave: Cold Wave is a very powerful, long range attack that is created in the hands. The user cups their hands and brings the cupped hands to their right side and then starts to gather a large amount of cold energy and shape it into a sphere. One the desired amount of cold energy has been created and turned into a sphere, the user thrusts their hands forward and fires the sphere in the form of a giant blue blast. This blast is capable of freezing even regular fire and it can cause a lot of damage.
 * Cryosphere: Cryosphere is the weaker version of the advanced spell known as Cold Wave. The user cups their hands and brings their cupped hands to their side. The user then begins to channel concentrated cold energy between their cupped hands and then shapes it into a sphere. Then by thrusting their hands forward, the user can fire the sphere at the opponent at high speeds, upon contact it can propel the opponent back with great force as well as cause minor frostbite

Ice-Make
Ice-Make is the molding magic version of Ice Magic. It allows the Tsuki to create and then mold ice for offensive, defensive, and even supplementary purposes. The supplementary purposes include creating a field of ice, covering the ice with ground, freezing a wound. There are two types of Ice-Make, Static and Dynamic, Tsuki is shown using both verisions expertly. Static Ice-Make allows the user to create inanimate objects while the other allows the Tsuki create animated creations.

 * Ice-Make: Slide
 * Ice-Make: Knuckle
 * Ice-Make: Kite
 * Ice-Make: Rocket: Ice-Make: Rocket, is just like Ice-Make: Gungnir except in the form of a rocket.
 * Ice-Make: Multiple Ice Clones: As the name suggests this spell is similar to the spell "Ice-Make: Clone" except it is on a larger scale. Instead of making merely one clone the user creates hundreds of clones. However, this spell consumes a large amount of magical power so it usually leaves Tsuki extremely tired.
 * Ice-Make: Blacksmith: Ice-Make Blacksmith is a spell that allows the user to create weapons. These weapons vary greatly in size and shape.
 * Ice-Make: Ice Knight:
 * Ice-Make: Knights of the Round Table:
 * Dry Ice Art: Dry Ice-Make is an extension of Ice-Make which allows Tsuki to create, manipulate, shape, and pressurize dry ice. Since Tsuki's ability to control her Frigiokinesis is rare, so is this magic. Which is fortunate for her opponents because Dry Ice-Make is on a completely different level than normal Ice-Make. This is art is separated into two sections: the molding magic half known as "Dry Ice-Make and the normal version which is known as "Dry Ice Art". The only difference between the two is one is more like a molding magic while the other acts more like Winter Magic, which means the dry ice is produced from Tsuki's body.
 * ​Dry Ice-Make: Burning Sword: Dry Ice-Make: Sword is very similar to its Ice-Make variant except that it not only cuts but also upon contact with skin it causes a chemical burn and the longer the blade is touching the skin the greater the severity of the chemical burn will be.
 * Dry Ice-Make: Burning Wall: This spell allows Tsuki to create a thick wall that is made of dry ice. Since the wall is made of dry ice anyone that touches the wall suffers from a chemical burn. The temperature of the wall his cold enough to freeze the water from a dragon instantly, this is shown during a light spar Tsuki had against Otohime.
 * Dry Ice-Make: Burning Fortress:
 * Dry Ice-Make: Floor:
 * Dry Ice-Make: Prison: This spell allows Tsuki to create a large rectangular prison made entirely of dry ice. The durability of this cage is enough to restrain Gyūki, despite his incredible physical prowess.
 * Dry Ice-Make: Clone: A somewhat simple spell that allows Tsuki to make a copy of herself made out of dry ice. The clone is able to move independently from Tsuki.
 * Dry Ice-Make: Multiple Dry Ice Clones: This spell is a larger scale version of Dry Ice-Make: Clone, instead of simply making one clone, the user can make hundreds of clones that are made out of dry ice. The clones are able to move independently from Tsuki.
 * Dry Ice Art: Dry Ice Bomb: Dry Ice Art: Dry Ice Bomb is perhaps the strongest Dry Ice Art spell. Tsuki brings her hands above her head and creates a giant sphere made of dry ice inbetween her hands. Once the sphere is created she highly pressurizes the dry ice making it an explosive substance. Once pressurized Tsuki throws the dry ice sphere at the opponent and upon impact it causes a very dangerous explosion. The sound of the explosion alone is capable of causing severe hearing damage to anyone nearby, including Tsuki herself. The temperature emitted from the explosion is around negative 109 degrees Fahrenheit. The explosion also emits a powerful shockwave as well as thousands of tiny shards of dry ice that can impale anyone within a 20 foot radius of the explosion.
 * Dry Ice-Make: Clone Bomb: This is spell is the exactly the same as Dry Ice Art: Dry Ice Bomb, except Tsuki's shapes the bomb into a clone. The clone is able to move independently from Tsuki.
 * Dry Ice Art: Dry Ice Aura:
 * Dry Ice Art: Dry Ice Twister:
 * Dry Ice Breath: Dry Ice Breath is less of a spell and more of an ability Tsuki possesses due to her ability to produce dry ice. Unlike other dry ice related abilities and spells, Tsuki is able to use this skill whenever she wants. This ability allows Tsuki to release the fog created from dry ice when it is sublimed. The fog can vary in thickness depending on how Tsuki wants to use it. This ability is generally used as a way for Tsuki to prevent herself from being seen. However, since dry ice is composed of carbon dioxide instead of water, the fog is composed of a highly concentrated carbon dioxide gas, which can cause an opponent could develop carbon dioxide poisoning if they are exposed to it for an extended period of time. Tsuki is able to control the concentration and density of the fog allowing her to control how slowly or quickly the opponent can develop carbon dioxide poisoning. The thicker and denser the fog, the easier it is for Tsuki to cause an opponent to suffer from carbon dioxide poisoning. Occasionally, Tsuki is able to incorporate her Frigiokinesis to freeze the fog, allowing her to freeze any one within the cloud of fog inside a sheet of ice or if Tsuki is lucky she is able to freeze them in a sheet of dry ice by supercooling the carbon dioxide. The latter is a lot more dangerous to the opponent due to the properties of dry ice, if one their body will be subjected to very painful chemical burns.
 * Dry Ice Art: Armor: This spell allows Tsuki to coat her body in a somewhat thick layer of dry ice. This allows her to be protected from most forms of physical attacks as well as cause the opponent to suffer from chemical burns if they make contact with it.

Teleportation Magic
Teleportation Magic is a type of spell that allows Tsuki to teleport herself, an object, or person to another spot instantaneously.

Requip
Requip allows her Tsuki to store items in a pocket dimension so that she can easily summon them at any given moment. It is beleieved that the only thing she stores in her pocket dimension is senbon and the Winter Sword.

Imperial Embodiment
Imperial Embodiment is a spell that takes a lot of magical energy, but in return it allows Tsuki infuse her body with Winter Magic which allows her to increase her physical and magical abilities. Just like everything, this has a couple of weaknesses that can put the user's body in danger. The first form of Imperial Embodiment is the easiest form to enter. When Tsuki enters this form her appearance changes dramatically to the point that she almost looks like an entirely different person. Upon entering this form Tsuki's hair lengthens and  turns the completely white while, her eyes turn the color of ice, and she grows five inches taller. Tsuki gains a noticeable increase in both physical and magical abilities when she is in this form. However, if Tsuki doesn't understand her magic then she can cause great harm to her body. In this form Tsuki has complete control over her Frigiokinesis ability and the power of her Arctic Presence increases greatly.
 * First Form

Winter Fist
Winter Fist is an open palm fighting style that is practiced among the Uintā Family. The attacks from Winter Fist consist of quick and accurate strikes that cannot inflict that much damage on their own. However, what makes this fighting style feared isn't the attacks, but how users incorporate Winter Magic to cause a lot of pain. Upon impact, users channel Winter Magic into the foe which can cause an intense physical pain. This pain can vary from a paper cut to phantom pains.

The weakness of this fighting style is how easy it is to predict the strikes. Users of this fighting style focus on trying to hit the head, neck, spine, and torso because it is easy to spread the pain from those places to the entire body.

Uintā Assassin Art
The Uintā Assassin Art is the name of the assassination style that is practiced among the Uintā Family. The Uintā Assassin Art focuses on killing their victims quickly and with little to no struggle. Due to this fact, practitioners focus on stealth, knowing how to quickly deal with obstacles, hand-to-hand combat, pressure points, and speed.

Uintā Family Mutation
Due to the magic they practice and the environment they live in, members of the Uintā family has developed a unique mutation. This mutation is usually marked with extremely cold skin, a low body temperature, very pale skin, and magic power with a cold feel to it. Their life in the extreme cold has caused her bodies to have the inborn ability to be complete immunity over the cold. In fact, Tsuki has the ability to grow stronger when she is in a cold environment or during the winter season. She also has the ability to absorb cold temperatures through her body.

As a member of the Uintā family Tsuki has the innate ability to masterfully control and produce the elements of their homeland which are: snow, ice, and the cold. Her ability to control and produce ice and snow is so great that she is capable of creating small ice storms. However, her ability to manipulate the cold is a rare trait and has such it isn't as easy to control as the others, this is shown by Tsuki's Arctic Presence.

Arcticus is a winter wasteland meaning that food is often scarce. Tsuki has the ability to go days or even months without having any food, water, or sleep still have the strength to fight at full power. Her families life of constantly fighting off predators has given her a significant increase in physical prowess as well the ability to safely go without sleep for two weeks. When you combine these two things you get a mage who, is able to fight for four days straight.
 * Enhanced Assassination: Due to Tsuki's assassination training with her family and the many assassination jobs she has been sent one, her skill with assassination has surpassed the normal level of skill to the point that is at supernatural levels.
 * Cryokinesis and Frigokinesis: As a member of the Uintā, Tsuki was born with the ability to create, produce, and have complete control over all forms of ice and snow with her mind. She is also able to control ice and snow produced from most opponents, allowing her to perform feats such as redirecting an act or using their ice to perform spells allowing her to use ice or snow related spells with the use of magic power. Tsuki is also able to increase or decrease the temperature of ice, allowing her to dramatically decrease the temperature of ice or increase it to turn it into cold water which she is able to manipulate due to her Winter Magic. As a child it seemed her abilities were exponentially strong so it usually got out of control, but this weakness disappeared as Tsuki grew older. Normal ice isn't the only type of ice she can manipulate, during the few times she has her Frigiokinesis under control she has shown the ability to manipulate dry ice once it is created using her Frigiokinesis.
 * Winter Storm Generation
 * Frigiokinesis: Tsuki is able to create and manipulate the cold. She doesn't have full control over this ability which means that she subconciously tends to drop the tempature around her to below zero 90% of the time, this effect is known as Tsuki's Arctic Presence.  During the few times she has control of this ability she has shown the ability to supercool things. By using the ability to supercool things she can turn the regular ice she creates with Winter Magic and Ice-Make into dry ice.

Blood Consumption
Blood Consumption is one of Tsuki's less known abilities. In fact, the only one who knows that she can drink blood is Itsuki. It is currently unknown why she keeps this ability hidden. Itsuki has said that due to Tsuki's unstable frigiokinesis, her prey often freezes from the inside out while she is biting them.

Magic Power
Noted by mages who have fought Tsuki, her magic power has a cold feel and when it is released as a magical aura it often reminds people of a cold winter night. Similarly to Kanami's electric magic power, it isn't a good idea to absorb Tsuki's magic power because when it absorbed it can cause the mage who absorbed it to suffer from minor hypothermia.

When Tsuki releases her S-Class Aura it causes the temperature to quickly drop, Itsuki has stated that if it is released long enough Tsuki's magical aura can create a small scale snow storm large enough to cause four feet worth of snow to accumulate on the ground. This is possible due to her mastery over Winter Magic.
