- - Miyuki Yukimura to Minami Katamizu and Tetsuo Omoriki in "A Talk about Your Quirk"

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. She's the protagonist of my fanfiction.

Appearance
Looking physically like a child, Miyuki is a girl of average height with a very flexible body, quite thin and toned due to her gym trainings. All those trainings highed up her physical condition, possessing now a small musculature. She has a small, childlike and round luminous face, always wearing a cute smile that emphasizes her happy personality.

She own shoulder-length white hair, slightly curly 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 crystal-shaped, inherited from her mother. Her skin is very pale and slightly frozen, due to an overuse of her quirk at her hands, feet, ears, waist and face. Her surgery left, in the middle of her chest, a big scar which is rarely seen, being covered by her clothes.

In the aftermath of her fight with Yeti, Miyuki got a long scar on her forehead and some on her arms and legs.

During school hours, she wears the U.A.’s feminine uniform and, unlike her classmates, 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 makes her hot.

Apart from her uniform, Miyuki wears outfits in the girly/feminine style, all her clothes being handmade by her. She, practically always, wears short clothes (like shorts, tank tops...) because she gets hot easily when too much covered but she can wear longer ones too.

Miyuki is seen by people, like her neighborhood, as a very beautiful and lovely girl, which makes her quite uncomfortable.

Miyuki’s hero costume is composed of a blue sleeveless gymnastic-like leotard, decorated with small crystals (which are hidden by her coat and skirt) and a fine white line that follows the outline of her leotard. Over it, she added a dark blue-ish hooded coat with fur that can be attached with a big crystal. Around her waist, she carries a belt with all her first aid kit. She wears a pair of long fingerless furred gloves which are blue-colored also decorated by small crystals on each finger, with a hole on each palm to let by her icicles easily. On each of her wrists, she has two blue thermometer bracelets. Miyuki added a skirt that looks exactly like her coat (dark blue color and furred), that covers her butt and attached on each sides by crystals, leaving the front uncovered. She sports a pair of blue thigh boot with the top diamond-shaped adorned with two big crystals, with ice-like soles and icicle-like heels that helps her to walk easily on her ice/snow. Around each ankle, there’s a small sparkly cloth, again, attached by a small crystal. On her head, to make her costume more beautiful, she wears a blue crown of fake icicles.

The winter version of her costume changed differently compared to the other characters because now her gloves are smaller and start at her wrist. She took off her skirt but kept her coat (though she often takes it off). Since she’s more strong in winter and because the air is colder, she’ll be able to strengthen her quirk thanks to it.

When Miyuki takes her yeti’s form, her facial expression is more aggressive as she gains four big canines and her eyes becomes triangular-like, likewise with her irises. Her nails transform into long frozen and sharp claws on both, hands and feet. She can literally stab anything with them and kill anyone. Miyuki can change her height, become more tall, but she doesn’t use this skill often because of its disadvantages. Her body becomes more muscly and hairy (white hair), people sometimes mistake her for a man.

Personality
Miyuki is usually extremely cheerful and smiley, she's a girl who's capable of getting along with everybody and befriend anyone who comes across her, actually loving to meet new people. She's very outgoing and sociable, some already told her that she inherited her parents' heartwarming smile and will not encounter problems in her future Pro Hero career. Regardless of that she has been bullied during all her middle school years, she remained optimistic since then, and tries to keep and spread only positive vibes. She always look on the bright side of things/people. While being optimistic, Miyuki is an easygoing person, it’s very rare for her to argue with someone as her bright personality allows her to gain the confidence of everyone. Plus, she hates being on bad terms with people and any other type of conflict, she always tries to do her best to not disappoint anyone and so, avoid those kind of situations.

Miyuki, despite being a teen, is overly acting and talking like a four-year-old child. Her immaturity can also be seen by her having temper tantrums when she doesn't get her way, being very impish to the extent that she already got caught - or sometimes others - in trouble and being excessively stubborn. Her childish behavior is not always bad, as Miyuki is not the kind of person who acts in a bad way every single time. Generally, it doesn't bothers her peers, family or anyone else. They find such an attitude quite adorable and tend to laugh at it - however, there's time when people around her are fed up and get angry at Miyuki - Although she has a quite immature personality, in serious or critical situations, like fights or trainings, she behaves with more maturity and seriousness.

She's as well, a person far too hyperactive and talkative. She can talk about everything and anything while moving or fidgeting, whenever and wherever she wants. Her restlessness can turn into a boisterous attitude, then doing sometimes sudden impulses. 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 to do so. But she has proved to be absolutely generous and selfless, basically, kindness itself. Sometimes a bit too much that she'll neglect her own well-being by privileging whoever needs to confide in her or just to talk about anyone's troubles and help them. She states that her friends and family are the most important to her, being afraid to loose them stupidly.

A trait of her that she recently started developing, Miyuki is very very 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, she stubbornly ignores them. Since they live 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. And if not, they will not allow her certain things but instead, do extra homework.

Her childish 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 still does it and continue until she gets scolded, even in class. Speaking of class, she also annoys a lot her teachers, being now considered as “dunce girl” by them, because of her bad attitude and grades in class. Miyuki is a bad student but manages to get at least the average grade, mostly by cheating. She rarely listens in class, preferring to play with her stuff or sometimes disturbing the class. Not only she gets told off a lot because of that but also she was sent multiple times to the principal. Her parents are also worried and irritated at the same time about their daughter’s grades and behavior, as they’re always telling off Miyuki for this but she rarely obeys to them. Her mother is less indulgent than her father, who prefers to encourage and help her with humor and patience instead of pressuring and yelling at her like her mother does.

Everyone first thought she just wasn't doing efforts because she didn't had the motivation to work. Furthermore, Miyuki, to hide the truth, kept finding excuses like "school is boring", "it's useless" or "it's not a big deal" whenever someone asks why her grades are too low, therefore nobody will find out about her difficulties in learning. She experiences, since she entered middle school, big difficulties in reading and writing. Her homeroom teacher, Shota Aizawa, was the first one to notice that his student only writes in hiragana and only knows a few kanjis, as for her, this writing style is quite hard to learn but manages to retain some by remembering the hiraganas written above them. Miyuki didn't tell anyone about this learning trouble because she found herself very pathetic and was ashamed of it, deciding to deal with it by her own but it only got worser. Nevertheless, Eraser Head and her classmates decided to help her in order to improve her grades and make her a better student, something that Miyuki has trouble to do seriously but tries to not forgot the importance of her grades and how cheating is bad for her. As she go along, she started to really get into it and got better grades.

She can be, sometimes, very insolent and can answer her teachers or parents back. Moreover, Miyuki is disobedient and doesn’t hesitate to refuse everything people tell her to do, preferring doing what SHE wants only, hence her extreme stubborness. Miyuki is, generally, very easygoing and not bitter (as she never held grudges), but when someone gets on her nerves, she can loose her temper and say swearwords or glare but people rarely takes her seriously with her child-like apperance and this has the knack of annoying Miyuki. Taking her yeti form to threaten them works better. And the only time she ever held a grudge was when her grandfather and 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 will kill him.

She has the sensitive heart of a young child that can be hurt easily if someone harms her. She's also emotional, you'll easily see and understand her feelings by only looking at her face. However, it doesn't help her a lot when trying to hide her feelings, being forced to explain what she feels. That's why people are very prudent when they talk to her. Owing to her sensitivity and fragility, when something very dreadful happens to Miyuki, she looses all her merriment while staying in her (abnormally) dark and quiet room. She also skips all her meals, water being the only thing that keeps her on her feet, with difficulty. She behaves like this for several weeks, leading to put her health in danger. With such a worrying frame of mind, those close to her will tend to try making her smile again but when Miyuki is harmed, she’s completely different from usual, she adopts a more rude and curt attitude, showing nastiness towards people. But, deep down, she would never hurt anybody, not at all. Miyuki bottles up her emotions when in front of somebody but will vent everything at some point as her feelings are strong. Most of the time, people forgive her without being mad, knowing it isn’t her fault. But she already wounded a lot of people and when it happens, she apologies right after. Miyuki feels the necessity to stay away from her loved ones while this period of time, as she doesn't want to bother them with her problems.

Other traits of her personality that she hides very well, it’s her fearfulness and stress, which caused her habit of biting her lips and fingers. It could be in a fight, before a competition or an important exam, on Halloween, or even a small object falling. Ironically, she quite enjoys horror movies and scaring people, but will take it badly if it turns against her.

In the end, we can see that Miyuki is quite good at hiding her deepest feelings, and that being too much cheerful and optimistic is just a “veil” for her to hide her lack of self-confidence. Ideed, she started loosing her self-esteem after what happened in middle school. Being an oversensitive girl, all the criticism and teasing she received during those years made her hate herself and her yeti side. It took her some time to regain all her self-confidence and fully appreciate her other half, but still managed to.

Concerning heroism, when fighting, her attitude doesn't change a lot. 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. 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, albeit she's also good in combat. Known as an overly active girl, she sometimes do things with impulsiveness, resulting in ruining plans. Miyuki remains very talkative, she has the habit of insulting and belittling her opponents in order to deconcentrate them, even though she's not usually very mean, villains are the only persons she doesn't like.

Abilities
Overall Abilities: Miyuki, who got into U.A. through official recommendations from All Might who was amazed by her, possessing an amazing strength and good mastery over her quirk, is an impressive fighter despite her childish nature. 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 decreasing the temperature of her surroundings with her energy. 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 quite good at any ranged combat thanks to her quirk which can be use in both attack and defense, in different ways. She can also use her 2 quirks at once or combine them in one attack. Her acrobatic fighting style combined with her incredible physical condition makes her amazingly skilled at melee combat.

Her sociability allows her to work with anyone. Being alone is not a problem for her but she still prefers cooperating with someone, as Miyuki states that she needs a person to work with so that her weaknesses can be made up. Her rapidity reduced a lot because of her disability, disadvantaging her far more, so she mostly uses her ice to move and avoids running for a long time and distance. Academically talking, she very bad but when fighting, she can be very brainy and come up with very cunning plans easily that'll turn the situation around at her advantage.

Miyuki already has some special moves that she invented (except Avalanche) before entering U.A. such as Icicle Rain, Ice Punch, Siberian Fog and Avalanche. Sometimes, when doing gymnastic skills, Miyuki loves to name them afterward. Her biggest weak point is her sensitivity. Miyuki will easily get disturbed if someone tugs at her heartstrings. Mostly people who know her enough would offend her on purpose in order to attack her afterwards.

Miyuki's capabilities impressed many Pro Heroes, including the No.5 Pro Hero, Mirko. The latter actually heard of 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, something that happens when her peers are hurt or when she feels provoked by someone. But she can also easily awaken it by her own. 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 unknown ability which allows Miyuki to switch between a tall or her normal height but this ability has some consequences like the trouble of controlling her other side every 50min during 5 days or keeping her yeti form for an hour. The more she gains in height, the more hard it will be to control herself. Being born with this mutation helps her greatly when fighting, as it allows her things that normal people can't have naturally.

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 and already has appeared on TV. She drew attention of many recruiters, became a great role model for young gymnasts. Now, her aim is to compete as an Olympian in any country. Miyuki included those 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).
 * Enhanced Flexibility: Besides her powerful quirk, Miyuki is very skillful. One of her incredible skills is her flexibility. She is flexible by birth, being a talented gymnast increased this skill. 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 even in stealth missions. Miyuki is considered as the most flexible student in her class.
 * Enhanced Agility: She became agile thanks to her gymnastics trainings and her other half. She gives the impression of a cat, she lands almost always on her feet, therefore, the skill makes her attacks more unpredictable, precise and quick. Miyuki is also able to dominate the combat easily by climbing on her opponent to confuse them, or trees to attack at a certain height, and this with an incredible simplicity.
 * Enhanced Reflexes: Miyuki has also 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 kicks or punches are also very hurtful that, when used, can lead to a destroyed building or several bones broken (in the case of a living being). It's for this reason that she prefers to use her quirk in training combats rather than hand-to-hand fights because she doesn't want to use her strength over innocent people and hurt them. Miyuki is able to awaken her strength locally or on her whole body without awakening her yeti side completely, just the strength. It makes her extremely good at hand-to-hand combat.
 * Enhanced Durability/Stamina: Miyuki is able to endure any type of attack, however strong or hurtful they are. Even injured, she never gives up and tries her best to last till the end of the fight. She, of course, has her limits and can be seriously harmed if she resists for a long time. Her yeti side or physical condition can be the reason of her strong durability.
 * Cold Resistance: Miyuki has a natural resistance to low temperatures, even to absolute zero. That's why her own temperature doesn't put her in danger. The reason why Miyuki has this natural resistance is still unknown, therefore, doctors and scientists came to the conclusion that it would be the fault of her other half. 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. Nevertheless, if her temperature drops below 5°C, her skin may be full of frost. It doesn't happened to her before so we don't know if it's true and dangerous or not.

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, but also a bit of english and french.

Cooking Skills: Due to her parents being very busy with work, Miyuki had to cook for herself plus her siblings. Her mother and grandmother are the one who teached her. Miyuki knows how to cook different dishes, like russian traditional dishes.

Fashion Designing Talent: Miyuki can create/design, sew and fix anything she wants easily like clothes, plushies, pillows and more. She learned it when she was young, with, again, her mother and grandma. It's one of the rare time of Miyuki showing a great sense of creativity. She uses her designing talent to solve problems in mathematics.

Singing/Musical Talent: Following a show that took place when she was in first year of middle school, Miyuki is also known for her "cute voice" and everyone agreed with the fact that she's a good singer but Miyuki doesn't believe them and claims that her voice is horrible. She's absolutely not interested in singing but though, she loves to mumble some songs while doing something or sing lullabies to her siblings. Miyuki can also play a bit of 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 or to grow it on any surface. Her ice can be shaped into any desired object useful for fights or random ones. Living beings can be created, however, she cannot give them life. Miyuki can also eject, from the palm of her hands or feet, icicles. They’re already made in her body so, when she ejects them, they’re really fast.

With snow, she can make different type of snow (the form of the snowflake varies) by controlling the temperature of it, make snowballs, snow heaps or hails and also generate snowstorms, blizzards and snowfalls. Miyuki has another ability which is being capable of freezing anything she touches with both her hands or feet or with her breath. Her quirk is sometimes called “Winter” as she can produce everything that happens in this season.


 * Her emotions can play a little role when using her quirk but only if it’s a very deep feeling. Like if she feels very angry, her ice will be more resistant, hard and her icicles more spiky. For her snow, it’s only the storms that will be more unrenlenting. Another example, when she’s sad or hurt, it becomes more soft and weak.
 * The frost she uses for freezing people/objects, is her own oxygen. Since her body’s temperature varies between 5°C and 10°C, her oxygen frosts inside her and she exhales normally through her mouth or, if she wants to, through her hands and feet.
 * Miyuki can control the size, thickness, resistance and density of her 2 quirks but she has to consume her energy. So the more her ice/snow is efficient, the more her energy will be drained. She can also control the abundance of her snow.
 * We can say that her quirk’s source is her frozen oxygen but it’s not really that. Miyuki can also store up cold air in her body or just eat/drink something very cold to strengthen her quirk (as snow is made of ice and air).
 * To grow ice/snow on a surface, it has to be at least damp or cold and of a certain radius (1 mile radius max.)
 * Miyuki can also freeze water to create ice. She’s able to control/manipulate ice and snow that doesn’t come from her body (like Shoto’s ice).


 * Later, Miyuki’ll learn that she’s able to control her quirk through telekinesis but she’ll use it only when really needed.

Her quirk hasn’t a lot of drawbacks when it comes to create/control/manipulate her 2 quirks. Her biggest drawback is heat and high temperatures. Miyuki cannot use her quirk in a hot place (like a fire) because it’ll melt easily but also because the high temperature will cause her unconsciousness for a couple of hours or even death if she’s not evacuated in time.

Then, we have the small drawbacks, her control over her ice and snow. First of all, Miyuki rarely managed to create big objects with her ice, only small ones. To be more precise, when she creates objects with ice, the process consumes her energy. So if it’s a small creation, Miyuki will keep her energy stored. Otherwise, if the object gets bigger, it’ll start drain up her energy until she becomes totally exhausted. But with the help of Shoto and intense trainings, she’ll learn how to create big creations without consuming a lot of energy. Same with her icicles, if she ejects a lot of icicles, her hands/feet are going to hurt her, even worse, she can bleed from her palms.

When she generates a blizzard, Miyuki has trouble controlling its strength as it’s her most powerful snow attack. Since snowstorms and snowfalls are less powerful, it’s easier for her to control them. So she prefers generating those small storms rather than the big one.

Another drawback is that because of her illness, breathing is more difficult for her as she lives with only one lung so she can only freeze within a certain radius or a small area of a flat surface (that actually looks like a big frostbite) and controlling her quirk through telekinesis causes her severe migraines and vomiting.

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.

Super 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 if she wants to block the doors, windows and any other type of opening or weakening her opponents with cold.
 * Ice Punch (アイス・パンチ Aisu Panchi) : Her forearm totally frozen and strengthened thanks to her supernatural strength, she knocks out her opponent by sending an abrupt punch toward him/her. Miyuki came up with this special attack when she was in hospital. She usually used Ice Punch as her last attack, before it evolved.
 * Double Ice Punch (ダブル・アイス・パンチ Daburu Aisu Panchi) : Here is the evolution of her Ice Punch. Now, she uses her 2 forearms to attack the opponent so, obviously, it has more power and efficacy as her 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 surrounds her. By raising her arm, all the icicles head towards the target. They are quite sharp so they can stab anything or anyone.
 * Iceberg (氷山 Hyōzan) : A special move that works for both, defense and attack ! Iceberg is her biggest object created so, after that, she looses enough energy to suffer from little unconsciousness (30min max.). The giant piece of ice can prevent the opponents from reaching Miyuki while throwing them far up to a quite long distance, depending on the opponents' speed. The name of this attack is the same as her father's hero name, as Miyuki said that Iceberg represents a lot her dad, defending and protecting her from anything bad. First used during the Hero Work Recommendation Project on Nabu Island, against Nine.
 * Snow Canon (スノーキヤノン Sunōkiyanon): By concentrating her snow quirk in one part of her body (hand or feet), Miyuki releases a considerable amount of snow that buries her opponents. At worst, it can cause them hypothermia if they stay for too long covered of snow.
 * Triple Storm (トリプルストーム Toripurusutōmu): 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 while obstructing their sight.
 * Miyeti (ミエティー Mietī): While awakening her yeti half, Miyuki's body turns into ice. It looks like Ice Punch but this time, her whole body gets frozen. An unbreakable defense and powerful attack, she gains even more power and durability than she already has.
 * Ice Board (アイスボード Aisubōdo): Miyuki creates a wide board of ice, and stands on it (thanks to her agility, she doesn't fall). Its utility is mostly for moving quickly in long distances, sometimes serving as a shield. Miyuki surfs with it like a snowboard, often using some snow as she moves forward.
 * Avalanche (雪崩 Nadare): Having access to this move only when she takes her yeti form, it's not only her most powerful attack 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. If anyone gets carried by it, they'll die instantaneously. As for Miyuki, it is very likely for her to die because it empties all her energy and several muscles and nerves get seriously damadged.

Equipment
Hero Costume: Her costume is made of both opaque and cooling materials, also quite revealing. 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) as she’s very flexible and her fighting style, acrobatic. But also because she can loose control in a fight and then, tear up her clothes.

Since Miyuki doesn’t like when her clothes are made by other people (because it never fits what she wants), she created her own costume by herself. Her parents contacted some acquaintances of theirs, costume designers, to get some special fabrics (heat resistant/stretchy materials…) and they kindly accepted. Then Miyuki made her costume when she was hospitalized.


 * Crys-Tard (クリスタード Kurisutādo): As a gymnast, her fighting style is very acrobatic and she’s very flexible, so it was obvious for her to make her leotard like a gymnastics one. Made of stretch and thin matter, it’s easier for her to move and execute her figures efficiently. And in case she loses control, it won’t tear up. 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 sun rays and heatwaves reaching her body since they weaken her quirk and herself. We can say that it’s also for beauty purpose because she didn’t take it off in her winter version.
 * 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 cold 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 sun rays and heatwaves reaching her body. It covers only her butt because it is more simple for her to move and put her skills into practice.
 * 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. As said above, Miyuki is able to freeze anything with her feet but she noticed that her boots prevented the frosted oxygen to pass. So she asked Mei Hatsume, from the Support Dept, if she could solve this little problem. Mei added some holes on the soles to let the frosted oxygen pass and thus freeze freely.
 * Crys-Crown (クリスクラウン Kurisukuraun): Miyuki wanted something on her head to look more pretty, but she thought that it will be better if this headgear had a utility. So actually, her crown is made of fake icicles and work 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.
 * 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 and popsicles. 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): When she’s fighting, Miyuki doesn’t have any idea of her body’s temperature and can faint at any moment. So Mei made her 4 bracelets that also act like a thermometer but this time, they detect Miyuki’s temperature by triggering an alarm system with a voice that tells her her temperature. The more her temperature rises, the more the alarm will be loud.

Trivia

 * Miyuki's base body temperature varies between 5°C and 10°C. If it rises between 10°C and 20°C, she'll be tired. Between 20°C and 30°C, it'll make her dizzy or sick. Finally, when it exceeds 30°C, she'll faint. Nobody knows the reason why her temperature is that low and why she can't resist to high ones, so a hypotesis has been made that it's all because of her other half.
 * 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.

 * For fashion designing, the way how she got into it is a bit weird. When Miyuki was young and had to choose clothes at the store, she refused to wear all the clothes that her mother offered to her and was driving her to despair. But Yukino didn’t gave up and found an idea: she started creating her handmade clothes by asking her daughter what kind of cut, color, item of clothing… she wanted. From then on, as she grew up, Miyuki started to create herself her own clothes and now all her wardrobe is full of handmade clothes. She spents a lot of time in designing, even in class. Now Miyuki never buys clothes at the store and wear only handmade clothes. Very economical !

Quotes

 * (To her classmates) "Since I was a little girl, I've always dreamed of being a hero after seeing my parents in action. But when my other classmates knew that I wanted to become a Pro Hero and that I planned to go to U.A., they just laughed, saying that I couldn't even help myself so why do it with others.. I thought they were right, but after some time and thanks to someone, I totally ignored all those teasing. Now, I'm gonna be a hero and will defend myself while defending others, so everyone will stop thinking about me as a coward and defenseless person ! I'm gonna prove them that I can do it."
