**Miyuki Yukimura** (雪村 美雪 *Yukimura Miyuki*), also known as the **Frozen Hero: Crystal** (凍ったヒーロー クリスタル *Kōtta Hīrō Kurisutaru*), is a student in Class 1-A at U.A. High School, where she got in through official recommendations and is training to become a Pro Hero.

She's the eldest daughter of The Frozen Heroes, a well-known duo of Pro Heroes as well as the granddaughter of the dangerous villain, Yeti. She's the protagonist of my fanfiction.

## Appearance

Looking physically like a child, Miyuki is a short girl with a very flexible body, quite thin and toned due to her gym trainings. She has a small, childlike and round luminous face, always wearing a cute smile that emphasizes her happy personality. Miyuki is described as a very cute and lovely girl, compliments that makes her quite uncomfortable.

She own shoulder-length white curly hair, which are divided in 5 blue strands; their color being due to her quirk. She has big beautiful shining eyes, they’re ice blue colored and her pupils are diamond-shaped, a trait inherited from her mother. Her skin is very pale and slightly frozen due to her body temperature at her hands, feet, ears, waist and face. Her surgery left a big scar in the middle of her chest which is rarely seen, being covered by her clothes.

During school hours, she wears the U.A.’s feminine uniform and when wearing it, she has the habit to roll up her sleeves, tie up her jacket around her waist and slightly loosen her tie and collar as it warms her up.

Miyuki’s hero costume consists of a light blue shoulderless leotard and over it, she added a small dark blue, furred and hooded mantle binded at the base of her neck with a big diamond. Miyuki also wears a pair of fingerless gloves covering her forearms, with furred cuffs and edges. They are also light blue-colored, with each finger beautified with very small diamonds and cut off on her palms to let by her icicles. On each of her wrists, she has two blue thermometer bracelets. Around her waist, she carries a belt with four pouches on the front and two larger ones behind. Her belt clip is diamond-shaped. Miyuki added a skirt looking exactly like her coat (dark blue color and furred) which she attaches on each sides by diamonds, covering only the butt and leaving the front uncovered. She sports a pair of light blue thigh boots with pointed tops adorned with two big diamonds, with ice-like soles and icicle-like heels that helps her walk easily on her ice/snow. Around each ankle, there’s a small sparkly cloth, attached by a tiny diamond. On her head, she wears a blue crown of fake icicles which is also a thermometer.

The winter version of her costume changed differently compared to the other characters because now her gloves are smaller, starting at her wrists, and she took off her skirt but kept her coat (though she sometimes takes it off).

When Miyuki takes her yeti form, her whole body is covered in white long hair, only baring her feet, hands, face and ears. We can also still see her curves like her breasts and her skin turns mauve. She gains four fangs (the lower ones being bigger than the upper ones), her eyes are sharper and smaller than usual with the irises adopting the same shape as the pupils, and wrinkles all around the eyes. Those features gives her a more aggressive facial expression. Her nails and toenails transform into long, frozen and sharp claws. The tallest Miyuki grows, the bulkiest she gets.

In the aftermath of her fight with Yeti during the Shie Hassaikai Arc, Miyuki got a long thin scar on her forehead and some on her arms and thighs. And due to her suicide attempt, her neck and both forearms are covered with scars.

## Personality

Overall, Miyuki has the exact same personality as that of a young child, both on the good and bad side. Usually, she is an extremely cheerful and smiley little girl, yet excessively childish, always looking on the bright side of life and possessing a youthful mind. Also very sociable and outgoing, she easily befriends and leaves her mark on people; as a result, many of them stated that her contagious gaiety and childlike charm makes them easily forget their issues whenever she crosses their path and that it’s also too hard to get mad after her. Furthermore they are sure Miyuki will not encounter problems in her future Pro Hero career thanks to her bright personality. However, people like Eraser Head and Katsuki Bakugo, who find her too much carefree, still thinks that her actual mentality will make it hard for her to progress as a hero.

Regardless of her hard past, she remained optimistic since then and tries to keep and spread only positive vibes, determined to move on as shown when she really wanted to befriend her new classmates after entering U.A. even if she was afraid of being abandoned. While having an upbeat demeanor, Miyuki is as well an easygoing person, it’s very rare for her to argue with someone as her merriment allows her to gain the confidence of everyone. But above all, she hates having problems with whoever because she's afraid of losing them, she always tries her best to not disappoint anyone and so, stay friendly with them. Also, she is a person who hates very few things unless they’ve traumatized her. As now, due to her sad experience in middle school, she hates discrimination and will not hesitate to stand up against it. And because of her grandfather, she shows lot of hatred towards villains. Though, after getting to know him more, she tries to understand their ideologies before passing hasty judgment. She will eventually give her all to help and save them.

Like said above, she is someone who has lot of childish manners, overly and always acting like a four-year-old child. Due to this, people (mostly those who are close to her) automatically call her by her first name, treat her like their own sister/daughter and always worry about her. Her classmates even nicknamed her "1-A’s Lil' Sister". Her immaturity can be seen in many different ways too, such as her having temper tantrums when she doesn’t get her way, being very impish to the point where she already got caught - or sometimes others - in trouble, being excessively stubborn, impulsive, messy, dependent and sensitive. It never really bothered her peers, family or anyone else; because her puerility is generally expressed through her cheerfulness and hyperactivity, also by the way she speaks, they find such an attitude quite adorable and tend to laugh at it. Nonetheless, there’s times where her flaws emerge, making people around her fed up and get angry at Miyuki. We can also notice that personality with her liking for cartoons, her plushy Mr. Shirokuma or when she makes drawings as gifts to thank someone.

As a result of her puerility, she’s as well a person far too hyperactive and talkative, yet also being very open-minded. She will show interest in anything and will talk about it without stopping while moving around or fidgeting. Additionally, she kept the innocent side of her inner child and therefore, people try not to talk about "adult things" when she’s near or cover her eyes whenever she might see that. If we take the example of Love, it generally don’t bother Miyuki as her mind doesn’t really understand this topic and she has never been into a relationship, but she will start blushing and stammering after realizing everything.

Miyuki also has a real sense of humor, she is a very funny person who is always ready to joke and laugh, just to put people in a good mood. Because of that, people often have the impression that Miyuki is a person who rarely pays attention to those who need something, that she never takes the time to listen to someone, being too much agitated and absentminded to do so. But she has proven multiple times to be absolutely generous and selfless, basically, kindness itself. Sometimes a bit too much to the point where she'll neglect her own well-being by privileging whoever needs to confide in her to help them. She states that her friends and family are the most important to her, being afraid to lose them stupidly. Though, it’s not the same when it comes to her own issues. Miyuki will keep it to herself because she fears of being a burden towards people. Unfortunately, she is someone who’s very emotional. Her emotions are quickly displayed on her face whenever she feels any kind of feeling because she is just incapable of hiding them.

Miyuki, as another result of her childish personality, is quite messy and disorganized. In her room, clothes are scattered everywhere and stuffs aren’t at their place, though she always has been told off by her parents about this, she stubbornly ignores them. Since she lives in Heights Alliance, she’s forced to clean up her room because Mezo and Eraser Head often check it to see if it’s tidy or not. It happens sometimes that Miyuki demonstrates impudence towards others. She will defy people when they tell her to do something she doesn't want, showing extreme stubborness.

Her immature behavior contributes to Miyuki being a little scamp; always trying to tease and annoy people by pranking them, although she knows and sees that it irritates them, she continues until she gets scolded. Her teachers started referring to her as "dunce girl" because of her non-appropriated attitude in class. Miyuki seldom listens during classes, she's mostly seen playing with her stuff, daydreaming or at times, unintentionally disturbing the class. U.A.'s faculty members and her parents alike relentlessly warns her against that type of behavior but she kinda has some trouble acting properly. Because nobody could understand such attitude, they just thought she didn’t have any motivation to work. And to hide the reality, Miyuki kept finding excuses like "school is boring", "it’s useless" or "it’s not a big deal" whenever someone asks her the question. It’s only after a long period that Miyuki decided to tell them the truth while Eraser Head noticed it for a while now. In fact, Miyuki long copes with high difficulties in learning, but didn't tell anyone about it because she nervously thought people would only laugh at her and so decided to deal with it by her own, vainly. Her homeroom teacher noticed it after checking deeply into her homework and tests, as she mainly writes in hiragana it was easy to notice. Nevertheless, Eraser Head and her classmates promised to help her in order to improve her grades and make her a better student, something that Miyuki struggles to do seriously but tries to not forget the importance of her grades. As she go along, she started to really get into it and got better grades.

Miyuki is, generally, very easygoing and chill with anyone. Even so, she can lose her temper if we get on her nerves. But people rarely takes her seriously with her child-like apperance and this has the knack of annoying her. Although Miyuki seems harmless, she states that anybody really ought to avoid provoking her as they'll only make things worse, in other words her enraged other half may awaken. And sadly, when it happens, she will hold a grudge against those who harmed her or anyone she cares about as shown when her grandfather, also known as the villain Yeti, badly injured her parents during their fight in the Shie Hassaikai Arc. Miyuki swore that their next fight will be his last one, meaning she planned to kill him.

She has the same sensitive heart as that of a young child which can be hurt easily. That's why people are very prudent when they talk to her but, however, those who are down on Miyuki honestly don’t care about her feelings and will purposely harm her. She even totally lost her self-confidence after being left facing years of bullying. Owing to her sensitivity and fragility, when Miyuki faces a dreadful event she loses all her merriment and completely shies away from people. She remains all day inside her darkened room while skipping every meal, leading to a poor health. With such an upsetting frame of mind, those around her would try to help her but in vain as Miyuki just ignores them. Furthermore, being haunted by an overwhelming pain, she sometimes replies in a unkind way and unwittingly hurts her peers. Miyuki feels the necessity to stay away from her loved ones while this period of time as she doesn’t want them to see her like that. Since it already happened once before, during middle school, Miyuki had numerous counseling sessions with her psychologist, Tomoko Shinri, and still has to this day. She was diagnosed with depression when she was still 13 years old but has somehow recovered from it by receiving the proper treatment. However, her psychologist still takes care of Miyuki because Tomoko’s afraid she will sink back into depression due to her fragile mental health, but also fears the worst like suicide. Miyuki is also a very fearful girl who fears lots of things but ironically, loves to watch horror movies and scare her friends. Nonetheless, she’ll take it badly if it turns against her. Whenever she experiences those moments of fearfulness, she becomes stressed out and starts biting her lips, a bad habit she possesses for a long time now.

As said previously, Miyuki lost all her self-esteem due to years of bullying. But she manages to hide it under her joyful smile and optimism. What she hated the most about herself was her yeti half, as people avoided her all because of it. That’s why she preferred not to tell her U.A. classmates about it. Nevertheless, when they finally got to know the truth, everyone was praising her for having such a powerful gift which made Miyuki gain more in confidence. She’s still, to this day, trying to love herself with the help of her friends, teachers and family.

Concerning heroism, when training she does it with lot of efforts, energy and merriment. When fighting she gets more focused as she knows that it’s a serious situation but still some of her childish manners remains in her. During both moments, the only thing that doesn’t change is her sociability. Miyuki can either work with a comrade or alone, but she still prefers cooperating with someone as she needs a peer to work with so that her weaknesses can be made up. She can be quite clever and analytic, though it doesn’t last for too long due to her sensitivity and insecurities gaining the upper hand in her mind. Her opponent’s unkind words can easily trigger Miyuki, making her less focused and hurt. Miyuki’s not the type of person who’s overly confident regarding her skills, knowing that she has a lot to do before becoming a Pro Hero but also because of the lack of self-confidence she has. Her aim of being everyone’s savior combined with her bright attitude makes her very good at rescuing. Known as an overly active girl, she sometimes do things with impulsiveness, resulting in ruined plans. Miyuki remains as well very talkative, she has the habit of insulting and belittling her opponents in order to deconcentrate them, demonstrating her childlike insolence.

## Abilities

**Overall Abilities**: Miyuki, who got into U.A. through official recommendations from All Might who was amazed by her amazing strength and good mastery over her quirk, is a highly impressive fighter despite her childish nature. Despite acting like a kid, Miyuki has lots of skills which comes off as really surprising, astonishing people from her friends to Pro Heroes. Indeed, when she was hospitalized, Miyuki trained a lot outside the hospital in order to know at least how to use correctly her quirk before getting into her new high school. She also considers her trainings as a sort of rehabilitation from her surgery. Her parents, from The Frozen Heroes team, Iceberg and Snow White, trained her as well by letting her participate in villains arrests, which increased her fighting capabilities a lot. Now, Miyuki has a great control over her quirk and knows how to and when to use it efficiently but didn't became aware of all her potential. She will discover new things she can do with her quirk like producing ice and snow through her feet or using telekinesis to control it. According to Eraser Head, if Miyuki is not yet conscious of all her abilities, it's because she doesn't have the required mentality for it. So, she's still improving her skills, wanting her parents and homeroom teacher to be proud of her progress.

Miyuki is amazingly good at any ranged combat thanks to her versatile quirk. She uses her cryokinetic abilities for everything by molding it into barriers, pillars, weapons and shields as well for mobility purposes by skating on her ice in different ways, but also by creating wide boards to stand on it and move forward while stacking snow, like a snowboard. Her frigokinetic abilities are mainly used for obstruction purposes and weakening opponents with cold, as well as building walls of snow to block opposing attacks. She can also immobilize by burying with snow. Her acrobatic fighting style combined with her other half abilities makes her amazingly skilled at melee combat.

Miyuki's capabilities impressed many Pro Heroes, including the No.5 Pro Hero, Mirko. The latter watched her fight against Yeti and was amazed by Crystal's talent and so decided to employ her alongside Yuri and Satomi. Her situation also saddened the Rabbit Hero.

**Yeti Abilities**: Miyuki’s other half awakens most of the time when she loses control of her negative emotions. But she can also easily awaken it by her own. She can as well activate it only on a specific part (arm, leg, torso, teeth...). So about the other half’s abilities, it grants her a superhuman strength, an enhanced agility and a plus, height control. About her height, it's an ability which allows Miyuki to switch between a tall (2800cm max.) or her normal height (153cm) but this ability has a drawback: the trouble of controlling her other side. The more she gains in height, the more hard it will be to control herself afterwards. Being born with this mutation helps her greatly when fighting, as it allows her things that normal people can't have naturally. Lack of training prevented her from using the full potential of her yeti abilities, but after accepting her other half she started working on it and now relies more on her mutation.

* **Enhanced Flexibility**: Besides her powerful quirk, Miyuki is very skillful. One of her incredible skills is her flexibility. She can bend herself in so many ways, do a split in any position with ease. This skill is very helpful when it comes to dodge attacks or when she wants to hide her presence.
* **Enhanced Agility**: Thanks to her gymnastics trainings and her other half, Miyuki demonstrates good agility. She almost always lands on her feet, therefore, making her attacks more unpredictable and quick. Miyuki is also able to dominate the combat easily by mounting on her opponent to confuse them, or trees to attack at a certain height, and this with an incredible simplicity.
* **Enhanced Reflexes**: Miyuki also has very good reflexes. For instance, when she's located in a elevated place and suddenly falls, she immediately creates a big post of ice or a big snow mattress so she'll not hurt herself in the landing. She can dodge easily any type of attack (weapons, quirks...) with her high jumps and suppleness.
* **Superhuman Strength**: Miyuki's other half granted her a supernatural strength that allows her to lift things that largely exceed her own weight. Simple but forceful kicks or punches can lead to a destroyed building, several bones broken, or as well to creations of powerful tremors. Miyuki is able to awaken her strength locally or on her whole body without awakening her yeti side entirely. However, when doing this she cannot use the entirety of her force. It makes her extremely good at hand-to-hand combat.
* **Enhanced Durability**: Despite her frail look, Miyuki is surprisingly tough and can weather multiple attacks without suffering significant injuries or collapsing. Moreover, by activating her yeti form on the aimed part, she prevents the attack from getting too deep as her body becomes thicker and harder. Therefore, she saves herself serious even lethal wounds.
* **Cold Resistance**: Passed on by her ancestors, it’s an unknown mutation possessed by all her family members and caused by their quirks. Miyuki has a natural resistance to low temperatures, even to absolute zero. That's why her own temperature doesn't put her in danger. Thanks to this, she never catches cold or gets frostbites (she can have some but it's really rare and does not affect her), and finally, she can't die of hypothermia.

**Artistic Gymnastics Talent**: Since she's 3, Miyuki practices artistic gymnastics. Thanks to her years of training, she became the Junior National Champion of Japan. Being one of the most talented gymnast of Asia, Miyuki is very famous internationally. She drew attention of many recruiters, became a great role model for young gymnasts. Nevertheless, because of her hero studies she has no free time anymore, her schedule being very busy. So she decided to stop competing as she wants to devote herself to her main goal: being a great hero. Miyuki included those gymnastic skills in her fighting style, being even more dangerous in close ranged combat. She often uses her surroundings as gymnastic apparatuses (cylindrical objects: uneven bars, horizontal wide posts: beam, slightly highed objects: vault).

**Dance Talent**: She dances a bit, as a simple hobby but also to include some moves in her gymnastic routines. She's very graceful.

**Trilingualism**: Miyuki can speak fluently russian, since it's her paternal language, and knows few words of english and french.

**Cooking Skills**: Miyuki is able to cook some russian traditional dishes, something her grandmother taught her. However since her parents are very busy, there's a servant in their house, so Miyuki rarely cooks for herself or her family. A skill that still surprises people as it doesn't match her usual kiddie attitude.

**Fashion Designing Talent**: Her mother and grandmother also teached her, when she was younger, fashion designing. Miyuki can create/design, sew and fix anything she wants easily like clothes, plushies, pillows and more. It's one of the rare time of Miyuki showing a great sense of creativity. Another unexpected skill that doesn't fit her personality.

**Musical Talent**: Miyuki can play a bit of piano and guitar.

### Quirk

**Ice and Snow** (氷雪 *Hyōsetsu*) also called **Winter** (冬 *Fuyu*): Miyuki’s quirk gives her the ability to create, manipulate and control ice and snow through any parts of her body, grow it on any surface -preferably damp or cold- or directly manipulate and control nearby ice/snow (Shoto's ice, for instance). Her ice can be shaped into any desired object, useful for fights or random ones. If it's a complex structure, Miyuki will have to consume lot of energy and the process, usually quite long, can raise her temperature. She can create only lifeless living beings. Miyuki can also eject, from the palm of her hands or feet, sharp icicles that can be controlled using telekinesis. They’re automatically made in her body so they’re really fast when ejected, furthermore, they are enough sharp to stab thick matters. With snow, she can make different type of snow by varying the snowflakes’ form. She then molds it into snowballs or hails for attack and snow heaps or walls to defend. She can also generate snowstorms, blizzards and snowfalls to reduce the temperature of her surroundings or obstructing the sight/moves of opponents. Her body's low temperature results in frozen oxygen, leading to the ability of freezing anything she touches with either her hands, feet or her breath. Miyuki can as well lower her surroundings' temperature thanks to it. Her quirk is sometimes called “Winter” as she can produce everything that happens in this season.

Negative emotions will make her ice almost unbreakable, the icicles will become spikier and snowstorms, blizzards plus snowfalls even more unrenlenting. When injured, her quirk will become softer and weaker. Miyuki can as well control the temperature of her 2 quirks to make it solid and long-lasting. When fighting against living beings, she adjust the temperature of her ice and snow so it won't harm her foes. She can control her icicles using her mind without experiencing drawbacks. Likewise with basic ice and snow but this time, she’s prone to disadvantages like vomiting and severe migraines. Shooting lot of icicles without disruption will make her hands/feet bleed.

When using her quirk, her body temperature stabilize at 0°C in order to increase her quirk's durability. That's why she has to be very prudent and avoid places or quirks that could drastically raise her temperature otherwise her power will lose force and her body will weaken. And moreover, there's no cold present in her surroundings that can strengthen her. A higher temperature will eventually cause her unconsciousness for a couple of hours or even death if she’s not evacuated/healed in time. By contrast, if she’s located somewhere with a very low temperature, she’ll kept getting stronger and stronger as her abilities are highly enhanced until her body becomes uncontrollable, even aggressive.

As said above, using excessively her quirk will raise her temperature and drain up all her energy until she becomes totally exhausted, and finally faints. To avoid this, Miyuki has to eat cold food and drinks regularly, at each meal in order to have a low temperature. To be sure her body stays in good form, she sleeps with the air-conditioning on so her body can recharge itself.

As part of her training, Miyuki would try to minimize her quirk's ineffectiveness in summer by creating numerous objects with ice continuously - increasing the objects' size gradually - while heaping up snow. As for herself, she would eat a lot of different cold food/drink and keep her temperature as low as possible, for a better control over it.

### Ultimate Moves

* **Siberian Fog** (シベリアン・フォグ *Shiberian Fogu*): By reaching her breathing limit, she expels a sizable puff of oxygen which freezes an entire room, depending on its size. Miyuki uses this attack when she wants to block the doors, windows and any other type of opening or weakening her opponents with cold.
* **Icy Punch** (アイシーパンチ *Aishī Panchi*): When using this attack, Miyuki's whole forearm is covered in numerous layers of ice and strengthened thanks to her superhuman force. She then sends a blunt hook to her opponent, knocking them out. Miyuki came up with this special attack when she was in hospital.
* **Double Icy Punch** (ダブル アイシー パンチ *Daburu Aishī Panchi*): This is the evolution of her Icy Punch. In this version, she uses her 2 forearms to attack the opponent, thus granting Miyuki more power and efficacy as the previous version. This was first used against Yeti during their fight in the Shie Hassaikai Arc.
* **Icicle Rain** (つららの雨 *Tsurara no Ame*): High up or on ground, Miyuki creates plenty of icicles that surround her in mid-air thanks to their telekinetic ability. By raising then lowering her arm, all the icicles head towards the target.
* **Iceberg** (氷山 *Hyōzan*): A special move that works for both, defense and attack. She summons a huge iceberg that bursts out of the ground. The giant piece of ice can prevent the opponents from reaching Miyuki while launching them far afield, depending on the opponents' speed. Iceberg is her biggest object created so, after that, she loses enough energy and body temperature to suffer from little unconsciousness (30min max.). This move is named after her father to pay tribute. First used during the Hero Work Recommendation Project on Nabu Island to protect the Shimano siblings from Nine.
* **Snow Canon** (スノーキヤノン *Sunōkiyanon*): By concentrating her snow quirk in one part of her body, either hand or feet, Miyuki releases a considerable amount of snow that buries her foes. Against human opponents, she adjusts the temperature so they don't suffer from hypothermia.
* **Eternal Winter** (永遠の冬 *Eien no Fuyu*): She generates a blizzard, snowstorm and snowfall at the same time. The three having a different force, when combined, it provokes a great raging storm practically unstoppable and quite hard to control. Miyuki uses Triple Storm when she wants to reduce her opponents movements with cold while obstructing their sight. The temperature drops so drastically that it completely freezes a large area.
* **Miyeti** (ミエティー *Mietī*): While awakening her yeti half, Miyuki's body turns into thick ice. It’s the same principle as Icy Punch but this time, her whole body gets frozen. An unbreakable defense and powerful attack, she gains even more force and durability than she already has.
	+ **Miyeti: Cooling Rage** (ミエティー 冷却レイジ *Mietī Reikyaku Reiji*): **///WIP\\\**
* **Avalanche** (雪崩 *Nadare*): This is Miyuki's most powerful ultimate move but also a lethal one. Miyuki raises her arm and collects an enormous amount of snow. Then, she lowers it and all the snow heads towards her opponent. Anyone who gets carried by it will die instantaneously. As for Miyuki, it is very likely for her to die because it empties all her energy, her body temperature goes over 30°C and several muscles and nerves get seriously damadged.

## Equipment

**Hero Costume**: Her costume is made of both opaque and cooling materials. Her body mustn’t increase in temperature otherwise her quirk and herself will be weak or even useless so that’s why she did her best to reduce the chance of overheating. Most of her clothes are stretchy and thin (actually the same material as Mt. Lady's costume) due to her acrobatic fighting style, but also because she can lose control of her yeti half in a fight. Since Miyuki doesn’t like when her clothes are made by other people (because it never fits what she wants), she created her costume by herself. Her parents contacted some acquaintances of theirs who work as costume designers to get some special fabrics (heat resistant/stretchy materials…) and they kindly accepted. Miyuki made her costume when she was hospitalized.

The diamonds on her hero costume are in reference to her Hero name, **Crystal**.

* **Crys-Tard** (クリスタード *Kurisutādo*): Having a very acrobatic fighting style and being very flexible, this leotard allows her to move without restrictions. Made of stretch and thin matter, if her yeti half awakens it will gigantify as she does. The leotard also releases cold air to avoid Miyuki heating up.
* **Crys-Coat** (クリスコート *Kurisukōto*): She can resist to very low temperatures, but not to high ones. So this coat is made of a matter that prevents the sunrays and heatwaves reaching her body since they weaken her quirk and herself.
* **Crys-Gloves** (クリスグローブ *Kurisugurōbu*): Made of the exact same material as her leotard, her gloves are super stretchy and release cold air. She shortened them in the winter version of her costume for the sole purpose of storing up the surroundings' air to strengthen her quirk.
* **Crys-Skirt** (クリススカート *Kurisusukāto*): Her skirt has the same purpose as her coat: preventing the sunrays and heatwaves reaching her body. It covers only her butt in order for her to move and put her skills into practice easily.
* **Crys-Boots** (クリスブーツ *Kurisubūtsu*): They’re also of the same matter as her leotard and gloves except that they’re not stretchy. They only release some cold air, to avoid Miyuki heating up. In order to avoid hindering her ability to freeze with her feet, her boots' soles have got some holes to let Miyuki freeze freely.
* **Crys-Crown** (クリスクラウン *Kurisukuraun*): During battle, she's unaware of the area's temperature which can be very problematic for Miyuki. So actually, her crown is made of fake icicles working as a thermometer. It shines when the air is cold. The light intensity will vary depending on her surroundings temperature, very bright if cold and light off if hot. The crown is made of a material that melts in presence of heat, which means that if she's somewhere with a very high temperature, her crown will start melting. It was made by Mei Hatsume, after the Hideout Raid Arc.
* **Crys-Belt** (クリスベルト *Kurisuberuto*): Her belt has pouches of different sizes where she carries some bags of ice cubes, cold water bottles, popsicles and her phone. It’s her customized first aid kit, in case her temperature rises. Her belt works as a fridge and generates some cool air to avoid her kit to melt/heat and keep them at a cold state.
* **Crys-Celets** (クリスセレーツ *Kurisuserētsu*): She received them alongside her Crys-Crown to deal with the same problem. Mei Hatsume made her 4 bracelets that act like a thermometer too but this time they detect Miyuki’s temperature by triggering an alarm system with a voice that tells her temperature. The more her temperature rises, the more the alarm will be loud.

## Trivia

* Miyuki's base body temperature varies between 0°C and 10°C. If it rises between 10°C and 20°C, she'll be tired. Between 20°C and 30°C, she will get dizzy or sick. Finally, when it exceeds 30°C, she'll faint. Passed on by her ancestors, it’s an unknown mutation possessed by all her family members and caused by their quirks.
	+ In fact, Miyuki will feel the heat around her only if she's exposed for too long at it, if the source of heat is very high/close, or when she's sick. Other than that, she doesn't feel heat because her body is constantly producing cold for her well-being.
* Her surname contains the kanji for "snow" (雪 *yuki*) and "town, village" (村 *mura*), and her first name contains the kanji for "beautiful" (美 *mi*) and "snow" (雪 *yuki*).
	+ Her name can also mean "beautiful happiness" if written with those kanjis: (美幸 *miyuki*), reffering her cheerfulness.
