Oyumi Jinsoku

Oyumi Jinsoku, also known as Midnight Rider: Shadowshot Ōyumi (ミッドナイトライダ: シャドウショット) is a student in Class 1-B at U.A. High School who is training to become a Pro-Hero. She is the daughter of Ginsen and Hashiru, granddaughter of Isogi, and the half-sister of Soreya. She is also the best friend of Zazaki and Suki.

Appearance
Oyumi is a fairly tall, athletic woman, set at around 172 cm, or roughly 5’8,” with a slightly muscled, but slim, hourglass-shaped frame. One of her notable physical features is her thin hair braid, extremely long almost without competition, which begins with a hairband of any chosen color, after her hair that is styled to part to her right. It then ends near the bushy bicolored tip with another hair hairband, which may or may not change color, depending on how she uses her Quirk or how she moves, or simply depending on the day for aesthetics. It’s a wonder to how she managed to maneuver around in crowds so conveniently with such an extensive braid without tripping or getting it caught somewhere.

She has long sidebangs purposefully fashioned to be uneven with one longer on one side and shorter on the other side, done with the intent to present an unsatisfying and uncomfortable vibe to onlookers with this lack of symmetry of her hair and to surprisingly contrast to the rest of her organized look. This intended choice obviously makes it appear as if she made an “error” on “accident.” Her long pointed ears poke out from behind her sidebangs and can move, tilt, and curl akin to a cat or dog based on her response and emotions or if she feels like it.

Sometimes she wears fake diamond stud earrings, although they are hardly noticeable due to the sidebangs being in the way, especially in the frontal view. Another notable detail is her pinkish-white ruffled collar, which she wears to stand out and provide an air of fanciness in her presence, although some would see this as something that makes her look more “clownish” or “harlequin-like” than anything. Her collar is studded with a large diamond-shaped gem, including one round smaller gem each on both the left and right sides.

Oyumi wears a white bandage on her nose from time to time, which some would say she wears either after getting injured or to improve her breathing through the nose, especially during allergy season. In reality, no one knows why she wears them. On her hip, she wears a long pinkish-white feather keychain that is attached to the belt on her skirt as a “good luck” charm and a reminder of her loved ones, both living and passed on. Or maybe she just likes birds. Or both? Oyumi is well-known for her playful and flirty smiles and her somewhat narrow, archer (no pun intended) and impish eyes with long eyelashes. Strangely, while her eyes are in fact silverish-grey, they were rumored to be multicolored, with “marble mixed” or “pearlescent” shades of pink, purple, green, and blue, although this may have been the result of reflections of colored lights like a mirror somehow and other objects in her surroundings.

Personality
Mostly, Oyumi is a bold archer who had a tongue for stern criticism and asocial tendencies, preferring isolation and pointing out flaws like hitting home when she feels so, showing her to be insensitive to others’ feelings. She prefers logic over emotions when deciding on what she wants to do. Oyumi can be condescending and sarcastic, which can annoy others around her. She is serious about her goal in surpassing her family as an archer and combatant and focuses on mainly what she is interested in and usually ignores not what she sees as “unworthy of her time,” which also reveals her to appear arrogant and self-centered. Oyumi is insecure about her place in her family and afraid of being forgotten and lost by history, which explains her determination to push to great lengths in becoming a strong fighter. She has a longing to disprove those that doubt her potential as a Jinsoku family member and Hero. She is strict with instructing, as most displayed when she trains melee combat with Zazaki due to her upbringing and her fondness of Shouta Aizawa’s way of teaching.

She is usually reserved and calm, despite being a critical cynic. But she can be very vindictive and emotional when she loses her composure in rare moments, as revealed when she encounters Orokai Ishokko again and talks to Zazaki about her history with him, where she was driven to tears and is prone to lashing out, yelling and was willing to unleash hell upon him. After her history with him and his manipulation, she became distrustful to those near her age. She is easily jealous and envies anyone who has a quirk relating to speed like O’Clock’s Acceleration, Hawks’ Fierce Wings, or the Shihai’s Kuroiro’s Black Quirk, due to not being born with the Acceleration Quirk her family was known to have. She can also get jealous of those who have the ability to have a wider arsenal of what to use with their Quirk like Tamaki Amajiki’s Manifest. Oyumi is competitive, especially in battles, and desires to one-up against her opponents in power and speed, and her competitiveness can be hinted when she sees Class 1-A as her rivals. The negative traits lessen down over the years in U.A. due to her interactions with the teachers and her best Zazaki, who the latter gave her the most positive reinforcements and encouragement.

While having unlikeable traits, she is not blind to kindness and is far from heartless deep down. After spending time with Zazaki, she undergoes a slow change of approach and personality, revealing a softer side, despite being stern with her the younger student. However, she panics whenever Zazaki passes out from using pushing too hard with her Steam Quirk and desperately carries her to a body of water as fast as she can to revive her. She is susceptible to feel guilt due to how she was looked at by her family over the years. Over time, she becomes more considerate towards others after discussions with teachers like Aizawa and Kan, as shown when she finally suggests helpful ideas to Class 1-B without showing snideness or glares. Despite not caring much for other students, she is quick to notice little traits she found unique to her like Ibara’s pure intentions with religious vibes, Jurota’s way of speech, and Reiko’s ghostly depiction in her demeanor.

Over the years, she develops a polyamorous heart towards a few people such as her crush on Aizawa, her slow-growing affection towards Hitoshi Shinsou, and a soft sympathy and admiration towards Tamaki Amajiki. Oyumi even has a guilty interest in Hawks, as she is not above looking photos Zazaki took for him, and blushing profusely from them, although she would often try to ignore him in person when he attempts to get her attention. She was not proud of this fact, however. It is possible that she may have feelings for Zazaki, or just values her more than anything in general, lover or not, due to her growing appreciation for her involvement in her life. This revealed that Oyumi, with enough trust built with her, values those who stand with her and those she cared about, regardless of what happens, like they’re her own family or more than that. With a strong bond with her, she can be grateful to have those she believed deserve to be called her “friends,” she speaks about said people in higher regard compared to initially (Depending on the length of the friendship) and will be adamant on protecting and caring for them whenever possible. This was proven from her entry in a diary she had, where she showed deep mutual affection and appreciation for her friend Zazaki. She does not expect to be repaid for whatever she does for an individual, mainly because she never was for helping her family in different tasks, both simple or complicated for her alike. But for those she loves, she is willing to repay them for whatever if they did her a favor. When she helps Zazaki heal her bruises and cuts after training, she rejects the latter’s offer to do something in return, but was inclined to buy her ice cream or whatever she likes to do like going to play volleyball. Despite using words to express her feelings in vocal form or in written form, she has shown to be a woman who prefers to use actions to reflect her views, especially if she values the person a huge deal, as proven when she left behind a box filled with objects on Zazaki’s desk that represent them, such as birthstones and flowers associated with their birth months and keychains that symbolize their constellation zodiacs signs before her absence.

When having a softer heart to open up with, she can be soft-spoken and gentle to anxious people like Tamaki and pessimists like Shinsou. She can be willing to respect those with intellect and traits that remind her of her own, whether it’s based on her own personality, like her straightforwardness and strict approach or her circumstances like being looked down at for not having a socially ideal Quirk.

When she grows a lot of respect for someone with heroic achievements and skill or gained enough trust with her, Oyumi is honest and unafraid to give them encouragement and express how she feels about them. Oyumi, with a new heart, was able to connect and relate to people who have a heroic heart and want to finally move on like Eijirou Kirishima. Her years in U.A. made her wise and helped her open up, so she is bound to give advice to those who need it, but with a small hint of rigidness, as seen when she tells Eijirou Kirishima and Zazaki that “flashiness does not determine one’s usefulness.”  She can see potential in others very quickly, but likely because of her newfound hope in her heart.

She has a slightly verbose way of speech and sometimes she lays out metaphors and uncommonly used words, which can be a little confusing to some. Although Oyumi is typically emotionless or grumpy, she can be easily embarrassed when singing is involved and would avoid participating in that particular topic, as a result of receiving negative feedback from strangers for her aimless humming and singing in public. She is easy to be inspired if she likes certain traits of something or someone, which can be seen when she takes on a somewhat “fancier” or formal look in clothing and her flirty and slightly impish demeanor, implying that she was motivated by Neito Monoma’s visual style and Setsuna Tokage’s playfulness and provocativeness. She had few Heroes that she admired such as Snipe, Eraserhead, and a retro Hero from 2 centuries before named “Bloody Marilyn,” which boosted her inspiration to train harder and hoping to surpass one day. She aspires to be like those she holds in high regard in skill and combat, such as her admiration towards Aizawa’s heroic competence.

As a child, she was loved dearly by the only person who cared about her, Ginsen, but was constantly neglected and emotionally abused by her mother, Hashiru to the point that she isolates herself from him and her half-brother, Soreya and found it difficult to form a close bond with either emotionally. While Ginsen tries his best to get the two half-siblings to interact, Oyumi had no interest in forging friendships or family bonds and preferred to train and study instead. She developed a negative outlook towards her family once the abuse expanded with her cousins ostracizing her, which greatly affected her ability to get along with her peers and co-operate with them in school. When Hawks first met her via Ginsen’s introduction, Oyumi was suspicious and avoided him, assuming that he was trying to trick her into another situation involving being bullied by her cousins. Although, she deeply craves a genuine friendship outside her family, she was unable to due to her distrust. She looked up to Lady Nagant and expressed this at some point, wanting to be as great as her with her similar quirk, and this fact became a topic of concern about Oyumi by her peers after the pro-hero was arrested. Despite her negative attitude, she still held on her ambitions to be not only as great as her, but to be greater than her, alongside her dream to be noticed by her family.

During middle school, Oyumi was nervous about how people would think of her after being left out constantly by her family and her classmates in elementary school. Her confidence and determination to get better and train to be stronger were a little bit regained when given a few compliments by her middle school classmates for her ability to transform her arms or hair into different kinds of bows. But it didn’t stop her from becoming a pessimistic “soldier” when starting out in U.A. High. She is a very rough person and maybe unlikeable, but her views when she writes them down or thinks in her mind appear to be more lighthearted and calm. Though she spoke harshly about her class, she still sees it as the better class compared to Class 1-A and still wrote mostly positive about her classmates in one of her diaries.

Alongside her nature of intelligence on the battlefield, partially her negative traits, and thanks to Zazaki's occasional mischievous antics, Oyumi has grown a somewhat impish side with the lightening of her heart, periodically joining her blue-haired friend in pulling a few pranks just to get a giggle out of them. She kisses Kirishima's forehead while he was asleep and places a white feather on him before slinking off to the distance and hiding before he had a chance to wake up. Her stealth-related experiences by her cousin Dokuya’s jumpscares became something she uses to mess with unsuspecting targets, such as Zazaki by slowly walking up to her without making a sound and shaking her as she grabs her shoulders, triggering a startled response. She relies on her intellect of trickery to deceive her target by using sounds to lure. She became a habitual teaser, cracking a few jokes with a few classmates with a small sly smirk and a sensual glare, even if the comedy fell flat or came off dry. Sometimes she would joke about how Kirishima and Tetsutetsu could have long lost brothers. During her moments with Shinsou after school, Oyumi would try to lighten up the mood with a bit of teasing of how his hair "looks like his head on purple fire" among other comments. She purrs when he's nearby just to get a reaction to him, knowing that he likes cats.

She is also a playful flirter, thanks to Zazaki, as seen when she is poking at Shinsou about his Quirk, telling him with a low and suggestive tone, "Don't go mind controlling me to like you now~" and may make suggestive comments in the same tone like “you could do so much with a Quirk like this… even for personal things~”  The latter side of her flirty aspect is hard to spot since she usually makes statements, complimenting certain people for their looks or personality, along with expressing her honest views. It is possible that she would play with the person’s hair as a way of affection and teasingly pamper, as when Oyumi plays with Tamaki’s hair, which results in Tamaki to stammer much more and blush profusely, much to her amusement.

Abilities
Enhanced Speed: She is incredibly fast, which is something her Quirk family, the Jinsoku, is renowned for. As a result of personal training and parkour, Oyumi can run as much high speed her body could allow her, a huge change from when she first started. Some, such as Zazaki, for instance, may say assume she has two Quirks or a “Combo-Quirk” because of this, although this possibility is debatable, even when being in the Jinsoku family. She is able to reach her friends, allies, or civilians and bring them to safety as quickly as how much short time it took her to arrive. She was fast to get her friend Zazaki to safety and a place where she will regain consciousness quickly whenever she passes out. Due to having more experience and her slim and flexible frame over time, she can escape most of Zazaki’s ongoing attacks during training and the latter would have to learn how to counter-attack and block her weak points on her body efficiently and fast enough instead of being bounced back.

Thanks to her rapidity, it gives her extra force to jump over gaps from ledges more cleanly and hop up certain vertical surfaces like walls of different textures. With her swiftness, she can use her developed reflexes to evade oncoming onslaught very easily, giving her enough to shoot precisely once more, but in a different pose. As she dodges, she is able to swiftly swerve and “slide” through open spaces that allow her to move to the next spot before striking again. She is quick to block offensive approaches and to grab arms of those who attempt to punch or slap her, sometimes later responding with flipping the person over if they would not compromise. With enough speed, Oyumi can use her bows to whack like blunt weapons, as well as grab and toss or slam enemies to the ground when possible, thanks to the open space between the bowstring and the bow’s limbs, but she rarely applies the latter method in combat, unless as a last-ditch use. Oddly, her ability to run so fast causes her to look like afterimages when she passes by people when in the process of using her Archer Quirk. She narrowly ties with Pony Tsunotori as one of the fastest in Class 1-B, thanks to her dedication to improving her body to be capable enough to move speedily.

Flexibility: Oyumi is slender and lithe, therefore having a somewhat graceful or fluid approach and her physique aids her in dodging efficiently in multiple poses that would be difficult to do in combat without thorough practice. Through being able to dodge strikes in various kinds of positions, she can land counterattacks in return as easily and speedily as her reflexes. In uncomfortable and cramped spaces, she is capable of slide through various openings in the clustered crowds without bumping into that many students or teachers nearby. She is also able to freerun parkour and use her flexibility and speed to her advantage to make her way around the city of Musutafu, along with an eye of precision of where to land and how to move her body. In several exams, Oyumi is proficient in quickly flipping or bending her body backward and twist her body like a wrung towel rag or a cat.

Strength: Most of her training helped her gain some muscle, despite remaining thin. She relies on weapons made from her Quirk or manufactured to land hits on opponents, such as her bows with mixed kinds of ammunition ranging from simple rocks to explosive arrows. If she had to, whether by choice or if she had to rest from using her Quirk too much, she may use melee-related combat techniques and weapons to compensate. If bare-handed, she would likely punch, scratch, or block with her guarded arms. Because of her slender and flexible, but sturdy body, Oyumi can move around to evade or block attacks and use her own as a swift counterattack since she built enough muscle to do so. If she wanted to, she could utilize her long braid of hair as a whip or a rope to traverse areas with gaps too large to jump over or areas too high to bounce to, something to use like a zipline, or restrain someone or something from movement like Shouta Aizawa's bandages. However, she rarely uses her hair like that, since it hurts her scalp and can damage her hair into breaking anyway. Her refined balance allows her to either stand on one leg or one singular arm as she swung her body around, shooting her opponent as she knocked them off their feet. Overall, Oyumi is naturally a ranged attacker and close combat is something even now she needs to work on.

Keen Intellect: Though among the students accepted into U.A. via recommendation for her academic success, Oyumi displayed a case of fine strategic intellect more on the practical side or “street-smarts,” being quick to adapt to different environments, therefore making her versatile. Thanks to her fast-thinking and versatile creativity, she observes the situation before thinking of ways she and her teammates can use objects around them to their advantage, such as using ice or rocks as ammunition and shields, wires and vines like ropes, and even using her hair as a whip and using her crossbows to grab, swing, and slam down opponents or a tool for acts similar to a zipline make way across great lengths instead of running along. She may use other strategies like using her surroundings to her advantage, such as using trees and rocks or boulders as walls for hiding and protection, kicking dirt or sand to distract and obstruct her opponent’s vision, or use objects like branches or rocks as melee weapons or ranged ammunition. While she is more inclined towards using bows, she is not afraid to use firearms like handguns and sniper rifles as Quirkless substitutes should her bows and arrows prove to be futile tools in the situation.

Oyumi has an eye for precision, being quick to spot weak points to strike and know when to do so. She managed to catch her cousin Dokuya off guard for the first time by sensing vibrations in the ground and intuition to find out how close by she is without having to turn around and see, then spun to kick up sand to surprise her right when Dokuya was about to “strike.”  Her practices on parkour helped build her understanding of where exactly to land, how to jump, and her fast-thinking with timing. She depends on her sense of timing to know when to shoot and dodge attacks, such as evading and countering Zazaki’s approaches.

She has a preference for utilizing stealth in her strategies. She trains to be a master in stealth, so she can deliver the deadly blow before the individual would get a chance to hear her come their way. Sometimes she finds it more beneficial to rely on running along buildings and other high structures like trees to jump opponents and from the dark in a sneak attack, rather than running head-on. If she doesn’t plan on going up and personal, she would use poisoned darts or arrows and shoot from her hiding spot before treading carefully.

Oyumi uses her intellect of trickery to mess around with villains by making them think she's in one place but is actually in another that is much farther away in the opposite direction by using sounds like bang snaps or smoke bombs. She also used whistles to lure in opponents before escaping off, then attacking from a different area.

Quirk
Bow: With this kind of Transformation-typed Quirk, a portion of Oyumi’s long braid of hair or a body part like an arm or leg can turn into any type of bow of her choice, ranging from conventional or ancient but strengthened or enhanced bows types to modern pistols crossbows. Thanks to her extensive training in archery-related combat, she became a force not to be taken lightly when using dual pistol crossbows. She can use any kind of object usable as a weapon, from darts, rocks, and knives to regular, poisoned, and explosive projectiles. But arrows are her preferred medium of ammunition. As her quirk evolves, Oyumi is able to shoot up to five arrows at once, then elemental shots such as fire arrows later on.

Her power does not last eternally, however, for she can only use her Quirk various sets of minutes at a time before tiring out, depending on how much she shoots from her Quirk-created bows with a seemingly “unlimited” capacity of arrows. This urges Oyumi to retreat to a potential hiding spot to rest until she is able to shoot again. The amount of time it takes for her to restore energy varies. Thus, she may use this Quirk for situations where the required time of use or minimal possible, or when the need for it is most, while using a supply of ammo, both Quirkless types and Quirk-made. She would resort to melee combat and other alternatives of ranged ammunition that don’t use up her Quirk for the time being, had her powers ever run dry. The string and the structure on her Quirk-made bows do not snap off, but feature dents as a sign of injury, depending on the severity of impact. With enough hits to her arms used as crossbows, for instance, the pain that comes after will force the bows to quickly revert back to her regular arms.

Equipment
Bows: Whether it's a temporary part of her body from her Emitter-typed Quirk or a manual one she carries in a holster or latched onto a back strap, Oyumi often possesses some kind of bow ranging from a traditional to modern bow or a crossbow in combat or training. She uses "Quirkless" variants as an alternative when needing to conserve and restore energy in her Quirk for a certain amount of time or out of preference. Most of them that she uses are made specifically to be very sturdy, but light and foldable to fit in a modest-sized holster, while few others are physical replicas of her Quirk-made bows, such as her Quirkless “Scorpion” crossbow replica.

Quiver: When using bows, a plentiful supply of various arrows is kept in a leather quiver with vine etching on it of high caliber nearby Oyumi’s bow holster or strap. Oyumi's first quiver was given to her by her father Ginsen as a gift on the first day in U.A. High School.

Darts, Knives, and Arrows: The arrows Oyumi uses have different types of arrowheads of her choice. The same is said for her darts and knives in unique shapes and sizes. They can be laced with chemicals suitable for sedating, poisoning, or causing hallucinations to enemies besides inflicting a bit of damage. While they can be used as an alternative to darts, her knives are typically used as a cutting utensil and a melee weapon.

Name

 * Oyumi’s first name contains the characters “大弓,” where “大” that can mean “great” or “large” and “弓” means “bow.” It can also mean “longbow.” Her surname is comprised of “迅速,” which can be translated to “fast, swift” or “streamlined.” Her name can be a reference to the “oyumi,” a nearly forgotten ancient Japanese artillery piece that first appeared in the seventh century, thought to be a type of complicated crossbow.
 * Ginsen originally planned Oyumi's name to contain the kanji that directly means "crossbow" (弩 or 弮) with the reading of "Ishiyumi" or "Ooyumi," and it makes sense, given her Quirk's theme (Although her powers were discovered much later), but decided on "大弓" with the reading of "Ooyumi" because he wanted the name to be convenient to write and have a simple, but more positive and "bigger than themselves" meaning, or a notable but memorable one.
 * Oyumi prototype name used to be either “Yuna” or “Touma” with surnames like “Kishimoto” and “Kawayashi,” the latter being a mashup of Japanese surnames, but were all scrapped upon her Miss Ryuza’s realization that parts of canon characters' names usually have meanings that are associated with their Quirks.  "Yumi" was also planned and was the name most likely to be used, but was also scrapped for "Oyumi" instead due to her learning of already existing fan characters of the same name.
 * The alias "Royal Sniper" was inspired by Monoma's Hero outfit.
 * Monoma also became Oyumi's motivation to dress up a tad fancier in public after seeing his outfit.
 * Oyumi uses more than one Hero name out of personal indecision of which name she would want to be referred to. Regardless, all of her Hero aliases refer to her ability of stealth, the dark themes of her appearance and attires, her capability of speed, and her choice of weapon.  This indecision is directly based on her creator's own because she could not pick one for her.
 * Her prototype name (Or Hero Name) in her concept sketch was “Swift Striker” before her name process began. Other names like “Black Arrow,” “Royal Sniper,” ”Shadowshot,” and ”Sharpshooter” were also considered.
 * “Night Rider” was a title used for a small group of Zelda OCs her creator developed, a group born and selected to guard certain areas of the Surface/Hyrule with their own chosen powers associated with said regions. It turns out to be the name of a blackish grey color. Miss Ryuza thought it would be cool to revive that old idea from 2011/2012. The names were associated with the color of armor the characters wore, such as “Crimson/Scarlet Night Rider/Nightrider,” and “Silver Night Rider/Nightrider.”
 * Despite the negative racial history of the term, Oyumi states that she is determined to "reinvent the meaning and transform it into a positive term to associate with good-hearted guardians chosen by the heart of nature to protect their respective homelands in the dead of night, rather than perpetuating its past's power, fear, and injustice."
 * Oyumi changed her Hero Name from “Black Arrow Night Rider” to “Midnight Rider” or “Midnight Sniper” to honor Midnight after the Paranormal Liberation War.

Family

 * Some of her family members have names relating to their profession and their speed-related Quirk. On Oyumi’s side, the "archery family," her father Ginsen (銀箭) means “silver arrow,” hinting that he is an archer and fast bowyer. One of her cousins Dokuya (毒矢) means “poisoned dart,” signifying her occupation in training as a speedy assassin, and her distant half-brother Soreya (逸れ矢) means “Stray arrow,” implying his issue about what he wants to truly do in life, although he works with his father in arrow-smithing. Some other relatives have names simply relating to their Quirks and not their job. Oyumi’s mother Hashiru (走る) means “to run” and her past third cousin Sousha (走者) means “runner,” and her grandmother Isogi (急ぎ) means “haste.”
 * The only person in her family who is supposedly indifferent about her existence is her half-brother Soreya, and the only one who tried to develop some form of bond was her father Ginsen.
 * Oyumi was said to have many cousins, but there are currently five known cousins in her story, along with unnamed ones from the Sogekihei, Funryu, Kasoku, Sokudoku, and Sumiyaka families.
 * Oyumi is afraid of being forgotten in time, which is also why she wants to surpass to be the best of the Jinsoku family.
 * Zazaki is the only person Oyumi found closest to family, despite both unrelated and coming from different environments.

Quirk

 * Oyumi was planned to have an Acceleration Quirk, but a "Bow" Quirk was chosen due to Miss Ryuza’s lack of knowledge about Quirks at the time.
 * Kirishima's Hardening, Bakugou's Explosion, and Kaminari's Electrification have been major influences to the Bow Quirk for Oyumi.
 * In regards to non-BNHA content, other inspirations include Linkle in Hyrule Warriors or the protagonists from the Assassin's Creed series, such as Edward Kenway in fighting styles and weapons.

Character and Relationships

 * Most of the compliments Oyumi got were about her sly and “flirty” eyes and expressions, as well as how her eyes sometimes looked like they were pearlescent or can change color because of the reflections in her environment and light.
 * Most of the select few people she finds interest in appear to her like reflections of her own character and life, with Amajiki’s timidness and shyness ringing familiar to how Oyumi was in middle school, Vlad’s intellect and caring for others seeming similar to her own intelligence and how she cared about her friends like Zazaki, Shinsou’s reserved and straightforward approach sounding familiar to her own, and Aizawa’s stern and strict attitude looking like reflections of how she expresses criticism as examples.
 * Visually, Oyumi was loosely influenced by Hitoshi Shinsou and Tamaki Amajiki in design, hence her fondness towards the two. While she was also inspired by Momo Yaoyorozu in design and partially in personality, she had little to no specific interaction with her.
 * Oyumi hated being talked to about the topic of her vocal talent like singing due to being discouraged from time to time for humming and singing in public. This ended up sprouting the repeated mentions by Neito Monoma about her hobby whenever they're in close proximity with each other and no one is nearby to hear him.
 * Oyumi thinks Eijirou Kirishima is “quite cute,” but she never expressed this opinion openly to prevent Zazaki from teasing her and pressuring her to get to know him more. This is also the case for other boys in her school such as Monoma and Tenya Ida and Pro Heroes, regardless of gender, like Eraser Head and Midnight.
 * Oyumi loves archery and prefers using crossbows over any other Quirkless ranged weapon. She nicknames one of her crossbows “Scorpion” another “Aculeus,” and another named “Nitros” for their usefulness with arrows, regular, poisoned, and explosive alike. The names given to her crossbows are three references to some of the fastest and most powerful crossbows, “Scorpyd Aculeus” and “TenPoint Nitro X.” A little too much on the nose there.
 * Some of her favorite foods are pies, any kind of savory stew on rice, and pineapple pizza.
 * Despite holding the belief of “actions speak louder than words” or “show-don’t-tell,” Oyumi writes in a collection of personal diaries she kept for years, which is why she has a thing for hard-covered journals
 * Speaking of diaries, she once expressed in one of her entries that she kept so many that the amount could have filled a small library.
 * One of the concept arts of one of her Hero Costumes references the symbol of her homeland, the Okayama Prefecture.
 * In the first concept art of Oyumi, the feather that hangs on her belt was much larger than the official drawing made for the profiles. The braid was noted to be “twice as thin, if not 3x” whenever she was drawn again. The face had paint that stretches across, like smeared blood or dirt or barbaric war paint. In her concept Hero Costume, she had brown boots black pants with a bright red stripe on both legs, white gloves, and a “blazer-like” top with long silk sleeves that droop like a robe to a point.
 * It's possible that either Oyumi collected the feather from somewhere or was given to her by Hawks.
 * Zazaki and Oyumi are like BNHA counterparts of their Miss Ryuza’s Beyblade OCs, Varuna and Yatsuma. Unintended, but ended up being so. Both Oyumi and Varuna are jaded and cynical women with troubling pasts or shortcomings while Yatsuma and Zazaki are the visually younger teens being major objects of support for them in improving as people, while in turn becoming stronger themselves. Varuna is taken care of by Yatsuma and her family, while Zazaki does so somewhat, although Oyumi does more of that. Oyumi and Varuna slowly warm up to their "sidekicks" and their relationship result from roommates or fan to an idol into pairs that equate to an unbreakable sisterly love, like Anna and Elsa from Disney's "Frozen." Zazaki and Yatsuma end up being part of the roles of "Guardian Angels" or the very people that become the major key to Oyumi and Varuna's recovery or improvement of character.
 * One contrast between Zazaki and Oyumi is that Zazaki had a rich family with an initially strong bond that grew strained as she got older, but she did not care since she was happy with her life, so she lived leisurely. However, Oyumi had her own rich family, but they had egotistical expectations looming over her head, so she was looked down at the moment she was born. That led to her being hard on herself, pushing so far in exercise and training to even find some validation in the family.
 * Oyumi and Vidia from Disney's "Fairies" have very close similarities. They are both speed-based (Oyumi is born in a Speed Quirk family and specializes it in her Archer Quirk; Vidia is one of the fastest-flying Wind-talent fairies), both have prickly shells and come off as rude, prideful and selfish until they slowly warm up to the other character(s) (Oyumi to Zazaki; Vidia to Tinkerbell or Prilla), they have long black hair fashioned like a tail, they have outfits that have similar shapes like their tops, and both have pointed ears behind their side bangs, and they both possessed something relating to feathers (Oyumi has a large feather attached to her belt; Vidia plucked feathers from Mother Dove to ground up into extra pixie dust).
 * Oyumi coincidentally share similarities with Ryuza’s Zelda OC, Stella, with a long and tall frame, thin, long tails of hair, narrow eyes, and a reputation of being very fast in combat and speed (Running; Flying), along with being born as part of a renowned family (The Jinsoku family; The Killer Stripes), and having seemingly cold personalities.
