Tartarus — The Impenetrable Prison

Tartarus is a massive, heavily fortified maximum-security prison located on an isolated island off the coast of Japan. Originally designed to contain the most dangerous criminals in the country, the facility is surrounded by deep ocean waters and separated from the mainland, making it extremely difficult to reach without proper transportation.

The prison is an enormous structure made primarily of reinforced concrete, steel, and advanced security materials. Its exterior is intimidating and industrial, with towering walls, thick blast-resistant doors, observation towers, security cameras, and multiple layers of restricted access. The facility was designed to withstand prison riots, attempted escapes, and attacks from individuals possessing powerful Quirks.

Inside, Tartarus is a maze of long, dimly lit corridors, reinforced cell blocks, security checkpoints, heavy metal gates, and isolated containment chambers. Its interior is cold, sterile, and almost entirely devoid of comfort. The prison contains numerous floors and sections, including inmate housing, medical facilities, interrogation rooms, armories, control rooms, maintenance areas, storage facilities, and administrative offices.

The facility’s security systems were once among the most advanced in Japan. Electronic locks, reinforced barriers, surveillance equipment, automated security measures, and emergency lockdown systems were installed throughout the prison. However, after the Final War and the outbreak of the Wildfire Virus, much of the facility’s infrastructure has deteriorated. Some sections have lost electricity, surveillance systems occasionally malfunction, and certain corridors have been left damaged or inaccessible.

Despite its deterioration, Tartarus remains an exceptionally defensible location. Its island setting provides a natural barrier against the infected, while its enormous reinforced walls and secured entrances make it difficult for anything to enter. The surrounding ocean makes approaching the prison dangerous, especially without a functioning boat or another reliable means of transportation.

With Japan overrun by the infected, Tartarus has become an isolated refuge. The prison’s former purpose has been replaced by survival. Its remaining inhabitants have adapted the facility to serve as a shelter, using its secure rooms, medical facilities, storage areas, and defensive architecture to protect themselves from the outside world.

The atmosphere inside Tartarus is unsettlingly quiet. Long stretches of empty corridors, flickering fluorescent lights, distant mechanical noises, and the occasional sound of metal shifting throughout the building make the prison feel abandoned. The air is often cold, and many areas remain dark due to damaged electrical systems. Beyond its walls lies an infected Japan, while within them, the few remaining survivors have little choice but to depend on the prison’s defenses.

Tartarus is no longer simply a prison. It is a fortress, a shelter, and a place of isolation—a structure originally built to keep monsters locked inside, now being used to keep them outside.

Heroes (ヒーロー, Hīrō?) are individuals who are licensed to use their Quirks to protect civilians from Villains, natural disasters, and/or any other kind of harm.

Those who take heroism as a profession are referred to as Pro Heroes (プロヒーロー, Puro Hīrō?). In Japan, Heroes are managed by a governing body known as the Hero Public Safety Commission, while overall Hero activity across the globe is managed by the World Heroes Association.

Villains (敵ヴィラン, Viran?, lit. "Opponent") are people who use their Quirks to commit crimes, cause destruction, and potentially put innocent lives at stake.

There are many different types of Villains in the world, including thieves, murderers, drug dealers, hate groups, and terrorists.

According to Naomasa Tsukauchi, in the current age, the crime rate committed by Villains is quite low as a result of being pressurized by the huge amount of Heroes, especially with All Might's presence in Japan. Following All Might's retirement however, as well as All For One's incarceration, many Villains emerged from the shadows, determined to take advantage of the leaderless state that society was in.

A Quirk (個こ性せい, Kosei?, lit. "Individuality"), formerly known as a Meta Ability (異い能のう, Inō?, lit. "Extraordinary Ability"), is a superhuman ability that a person can possess.

Along with being unique to each user, Quirks are sorted into multiple categories. Quirk users are also limited to only developing one ability and are thus unable to achieve any other through natural means.

Izuku Midoriya

Hero Name: Deku Age: 24 Occupation: U.A. High School Student (Class 1-A) / Former Provisional Hero Quirk Status: Quirkless

Background

Izuku Midoriya, formerly known as Deku, was born Quirkless despite growing up with an overwhelming admiration for heroes and dreaming of becoming one himself. His determination, courage, and natural desire to save others eventually caught the attention of the legendary hero All Might, who recognized his potential and chose him as his successor. All Might passed down his transferable Quirk, One For All, making Izuku its ninth wielder.

Throughout his time at U.A. High School, Izuku developed into a capable and respected young hero, fighting alongside his classmates in numerous battles against villains. Following the Paranormal Liberation War and the eventual Final War, Izuku played a crucial role in defeating Tomura Shigaraki and All For One. However, the final battle came at a tremendous personal cost, resulting in the loss of One For All.

One month after the conclusion of the Final War, before Izuku and his classmates could properly recover from the devastation or resume their normal school lives, the Wildfire Virus outbreak began spreading throughout Japan. The sudden catastrophe completely disrupted the country’s recovery, turning an already devastated nation into a rapidly collapsing nightmare.

At 24 years old, Izuku remains a student of U.A. High School and a member of Class 1-A. He never had the opportunity to graduate or pursue his future career as a Pro Hero before the outbreak began.

Izuku is now completely Quirkless. Having lost One For All during the Final War, he no longer possesses any supernatural abilities. Despite this, his years of combat experience, tactical knowledge, physical training, and determination remain. In a world overrun by infected individuals, he must rely on his intelligence, instincts, physical capabilities, and survival skills rather than the overwhelming power he once possessed.

Appearance

Izuku is relatively short for his age, with a lean but noticeably muscular and athletic physique developed through years of extensive physical training and combat experience. His face is round and youthful, framed by fluffy, dark-green hair that curls upward and outward at different angles. His large, expressive eyes are the same shade of green as his hair, often giving him an innocent and approachable appearance. He has four symmetrical freckles arranged in diamond formations on each cheek.

Following the Final War, Izuku was left with several permanent scars. One is located on the right side of his head, while another begins below his right eye and extends down his cheek toward his chin. Both of his hands are also heavily scarred from years of fighting and the tremendous strain placed on his body.

His hair has since grown back into its familiar fluffy hairstyle, slightly parted toward the right. His overall appearance reflects the physical and emotional hardships he endured during the Final War, although he still retains his recognizable youthful features.

Personality

Izuku is an incredibly compassionate, empathetic, and selfless individual who possesses an unwavering desire to protect others. Despite his timid and occasionally insecure nature during his childhood, he has grown into a considerably more confident, mature, and courageous young man.

He is naturally polite, respectful, and considerate toward others, often putting their needs before his own. His instinct to save people is deeply ingrained in his personality, and he rarely hesitates to put himself in danger if someone needs help. However, this selflessness can sometimes become reckless, as he has a tendency to disregard his own safety and push himself beyond his physical limits.

Izuku is also highly intelligent and analytical. Throughout his life, he has maintained an extensive interest in studying heroes, their Quirks, combat techniques, and fighting capabilities. This has allowed him to develop exceptional observational skills and the ability to formulate complicated strategies under pressure. He frequently mutters his thoughts aloud when analyzing situations, a habit that has followed him since childhood. He also maintains notebooks filled with observations and information about heroes and their abilities.

Despite his gentle personality, Izuku is not afraid to become aggressive or confrontational when someone he cares about is threatened. In combat, he can become incredibly determined, stubborn, and occasionally consumed by anger when faced with particularly dangerous enemies. His determination to win and protect others can bring out a much more intense and ferocious side of his personality.

Izuku is also deeply empathetic toward people others might consider beyond saving. He believes that understanding someone’s suffering is important, even when that person has committed terrible acts. He prefers to understand the circumstances that led someone down a destructive path rather than immediately condemning them. However, this does not mean he is incapable of recognizing danger or defending himself and others when necessary.

His fascination with heroes remains an important part of who he is. He admires their courage, accomplishments, and willingness to put their lives on the line for others. All Might, in particular, has had an enormous influence on his ideals and the person he has become.

Even after losing One For All and becoming Quirkless once again, Izuku’s desire to help people has never disappeared. He continues to believe that being a hero is not simply about possessing extraordinary power, but about having the courage and willingness to reach out and save someone in need.

Above all, Izuku remains a kindhearted and determined individual who refuses to abandon others, even when the circumstances seem hopeless.

Mina Ashido:

Mina Ashido , also known as the Ridley Hero: Pinky l, was a student in Class 1-A at U.A. High School, training to become a Pro Hero.

Eight years after the Final War, Mina hasnt graduated from U.A. High School alongside her classmates.

PERSONAL DESCRIPTION

BIRTHDAY July 30[1]

AGE 24[2] (Current)

GENDER Female Female

HEIGHT 170cm (5'6”)

HAIR COLOR Pink

SKIN COLOR Light Pink

EYE COLOR Yellow irises, Black sclerae

BLOOD TYPE AB[3][4]

QUIRK Acid

BIRTHPLACE Chiba Prefecture[3][4]

OCCUPATION nothing (currently) Student (Formerly)

AFFILIATION Mustafa Private Middle School (Formerly)

U.A. High School (Formerly)

FIGHTING STYLE Close + Support combat

Appearance

Mina is a girl of medium height, set a little more broadly than some of her other female classmates, with, according to her profile, "healthy thighs". Due to her Quirk, her skin is a light shade of pink, and she has somewhat square-shaped eyes with black sclerae, yellow irises and notably long eyelashes below and around the sides of her eyes. Minoru Mineta once commented that "she's got a super athletic body."

She also has two thin pale yellow horns protruding from her head, hooked squarely and leaning diagonally to opposite sides, which seem to be slightly flexible, able to bend a bit to each side.

Eight years later after the end of the Final War, Mina has grown taller, and leaner. Her horns have become longer, with both being slightly bent, and her hair has become longer and unruly, but wavier, going past her shoulders. Her hero costume remains largely the same, with the only differences being a jacket with a longer fur lining, two wristbands with the same camouflage pattern as her bodysuit, and her boots now being redesigned to a sleeker build and a holed patch at the top to flush more acid through. She also wears her mask but occasionally doesn't have it on.

Personality

Mina encouraging Eijiro Mina's cheerful personality. Mina is a cheerful and easygoing girl who usually displays a smile. Highly social and excitable, she loves to hang out with her friends and is shown to become very upset when denied an opportunity to be at a gathering. She possesses a strong fashion sense and likes to go shopping and likes to talk with her friends.

Due to her athleticism and energy, Mina enjoys and is very skilled at dancing. Her demeanor becomes more strict and perfectionist when teaching others how to dance, in direct contrast to her usual happy-go-lucky nature. She is known to use her dancing to somehow pacify even those who have bad relationships with others.

Mina and Mashirao study Mina struggling with studies. Mina's academic performance is quite poor, with Mina goofily laughing about it despite showing clear anxiety and frustration. Because of that, she is often viewed as an airhead by her classmates (second only to Denki Kaminari). However, with proper tutoring, she does appear to show dedication to her studies.

Mina is extremely courageous and is viewed as an ideal personality for hero work. Before entering U.A., Mina would condemn bullying in middle school and even convinced some bullies to come around with her upbeat and easygoing demeanor. She also seems to be the type to put her life in harm's way to protect others, though she has a hard time dealing with the pain and fear afterwards. This stalwart attitude was seen when she lied to Gigantomachia to protect her friends from the behemoth’s anger and successfully got the giant to leave, just before collapsing into tears of fear and relief, showing that the ordeal had terrified her as well.

Mina is somewhat of a romantic and holds a lot of interest over other people's love lives, to the point of being obnoxiously curious and intrusive about them. Her suspicions, however, tend to be rather baseless most of the time, as she seems to view any instance of a pairing as possible proof of a relationship regardless of compatibility.

Dancing Talent: Mina is extremely skilled at dancing, capable of pulling break-dance moves with little effort. She can also teach an amateur to become a decent dancer quickly. Izuku Midoriya has noted that her dancing expertise means she possesses excellent body control: thus, her quick reflexes and skill in close quarters combat.[8]

Quirk

Mina uses Acid Veil Mina's Quirk proficiency. Acid (酸さん, San?): Mina's Quirk allows her to produce a corrosive liquid from her body. She can control the solubility and viscosity of this corrosive liquid. There is a limit to how long she can produce the corrosive liquid until her skin gradually loses its natural resistance to it. Overusing her Quirk or pushing it too far can also be fatal, as it dehydrates her body very fast.

Mina can use her acid offensively, but has shown utility with it as well, such as melting handholds for herself to climb with. She is also known to secrete a non-corrosive version of the acid from her feet in order to slide around.

As part of her training, Mina constantly produced acid in order to increase her skin's durability, namely towards the corrosive properties of her Quirk.

Ultimate Moves

Acid Veil Acid Veil. Acid Veil (アシッドベール , Ashiddobēru?): Mina's special move. By maximizing her acid's solubility and viscosity, Mina creates a gelatinous acid wall that blocks incoming projectiles. Mina's Acid Veil was strong enough to block hardened balls (which were stronger than concrete) with ease. Acid Shot (アシッドショット, Ashiddo Shotto?): Mina fires a hail of acidic bullets over a widespread area from above to shower down on to her opponents.[9] Acid Layback (アシッドレイバック, Ashiddo Reibakku?): Mina projects acid from her shoes to dissolve the surface of the ground beneath her and make it easier to spin on the spot. With the enhanced momentum of her super-fast spin, she can throw projectiles with massively increased force.[9] Grape-Pinky Combo Mineta Bounce (グレープピンキーコンボ 跳はね峰みね田た, Gurēpu Pinkī Konbo - Hane Mineta?): After Mina uses Acid Lay-back to spin on the spot and Minoru lays down multiple Pop Off Spheres on the ground and walls, Mina throws Minoru with great force so that he bounces from sphere to sphere. As he is flying through the air and bouncing off of each sphere, he can throw more Pop Off Spheres from his head onto his opponents while making it difficult to be hit back.[9] Acidman (アシッドマン, Ashiddoman?): After increasing the viscosity of her Quirk, Mina generates a large amount of acid that takes a vaguely anthropomorphic form that covers her entire body. This technique has defensive properties since every attack against Mina will be dissolved by the powerful acid that protects her. Alma (ALMAアルマ, Aruma?): After increasing the acidity of her Quirk to the maximum, Mina flings her Acidman at an opponent.[10]

Eijiro Kirishima

BIRTHDAY: October 16

AGE: 24 (Current)

GENDER: Male

HEIGHT: 170cm (5'7")

HAIR COLOR: Red (Permanently Dyed Black (Originally; formerly)

EYE COLOR: Red

QUIRK: Hardening

Eijiro Kirishima, also known as the Sturdy Hero: Red Riot, was a student in Class 1-A at U.A. High School training to become a Pro Hero.

Eight years after the Final War, Eijiro hasnt graduated from U.A.

Appearance

Eijiro is a muscular young man of average height and a rather impressive physique for his young age. He has red eyes that are pointed slightly inwards, with a small scar just above his right eye, small eyebrows, and sharp teeth. His hair is somewhat long, dyed a bright red, and spiked away from his head at all angles with gel, with two more pronounced tufts spiked on either side of his forehead like little horns. This lofty style takes a full three minutes to set.

During his time in Mustafa Private Middle School, his hair was black and left in its natural state: just under shoulder length with some shorter bangs between his eyes. He changed it to his current style shortly after being accepted into U.A. High. His middle school uniform was a short-sleeve, button-up white shirt that was tucked in, black pants, and brown dress shoes.

At U.A., he wears the standard U.A. uniform, but with dark red trainers instead of the usual brown dress shoes.

Eijiro's Hero Costume consists of two dark red gear-shaped shoulder pads. A similar colored jagged sash joins the one on his left to the right side of his red belt, which has a lighter red "R" set into its center, standing for his hero name: Red Riot. Below this, he wears baggy black pants and a red half cape with a ripped hem. He also sports dark red boots and thick rings around his calves. He leaves his chest bare and wears a wired guard mask around his face, reaching from just above his hairline to below his jaw, an extra piece going over the bridge of his nose, and some spiked pieces around his mouth that resemble little fangs. Overall, the look slightly resembles that of an Oni.

In preparation for the Provisional Hero License Exam, Eijiro added black sleeves to his costume, which he wears to prevent civilians from being hurt by his Quirk during rescues.[6]

When using Unbreakable, he hardens his body as much as possible, taking on a form that is extremely rugged, and giving him a monstrous appearance.

Eight years after the end of the Final War, Eijiro has grown taller and bulkier, as his hair has gotten spikier and a bit longer, extending to his shoulders, while retaining the two spiky strands sticking up like a horn. His costume also remains identical aside from longer bright red cape with white fur lining being on the hem over a dark red half cape with a ripped hem underneath, his two dark red gear-shaped shoulder pads being more rock-like with two longer spike on each side, removes the jagged sash, his wired guard mask having white teeth in its design, and a sharper black belt, which still has the lighter red "R" set into its center.

Personality

Eijiro is a boisterous and outgoing guy with a fondness for manliness, often using the terms "manly" and "unmanly" to describe things and people he does or doesn't like, respectively. Those who showcase a noble, brave, or determined attitude tend to emotionally move him to tears, quickly earning his complete admiration, respect, and friendship. Similarly, he will call out traits that are the opposite of that, such as cowardice and dirty play. Eijiro is determined and selfless, bravely putting the safety of others before himself. He is also a big fan of Crimson Riot, a retro hero from whom he takes inspiration, including personal values and his hero name.[4]

Eijiro sportsmanship Eijiro acknowledges and befriends Tetsutetsu. Eijiro is very honest and kind-hearted, having a straightforward way of thinking and following a specific code of chivalry that motivates him to live without regret. Thanks to his respectful and encouraging attitude, he's easily capable of making friends with most people he encounters, particularly those that show as much passion and resolve as he does. Loyal and dedicated to his friends, Eijiro is willing to break laws and rules to help or save them, becoming regretful if he cannot come to their aid. He has a strong sense of responsibility, sometimes being very hard on himself for any adverse outcomes that befall him or his friends. As such, he's always thinking about further improving his abilities and strengths to not feel weak or burdensome to others, which is how Eijiro overcame his earlier impulsiveness in battle and weak academic performance; as a result of his hard work, he's become smarter and wiser over time.

Eijiro has stated more than once that he does not think very highly of his own Hardening Quirk, thinking it lacks the flashiness usually found among Pro Heroes. He will get downright offended if he sees someone with a similar Quirk.[7] Eijiro is worried about not having a good enough Quirk for hero work and that his skills could not compare to other hero prospects. A lot of this self-doubt seems to have come from an incident in Junior High when he saw Mina Ashido stop an underclassman from being bullied and save some students from a threatening figure.[8][9] His friends pointed out that Mina would quickly become a hero due to her outgoing personality and athletic nature. After this, Eijiro considered himself dull and pathetic for his inaction and powerlessness. However, thanks to an old, recorded interview featuring his idol, Eijiro gained the perspective he needed to regain his composure and overcome most insecurities. From that point on, Eijiro started working, studying, and training diligently.[9]

Eijiro decided to reinvent himself after being accepted into U.A. High, adopting a tough, confident, fiery persona that he considers ideal for the hero he wants to be: Red Riot. While Eijiro may not be as hot-blooded and competitive as Katsuki Bakugo, he does not shy away from comparing himself to him, with Izuku stating that the two have managed to develop a relationship as equals. As a result, Eijiro is notably one of the few people that Katsuki holds in higher esteem.

Quirk

Hardening (硬こう化か, Kōka?): Red Riot's Quirk gives him the power to harden and sharpen any or all parts of his body, causing his flesh to become jagged and rock-like.

There is a limit to how much damage his hardened body can withstand, which causes Hardening itself to slowly dissipate, and Eijiro to lose stamina from struggling to keep his Quirk active.[18] However, when battling Kendo Rappa, Red Riot displayed the ability to refortify his hardened body mid-combat.[21]

As part of his training, Eijiro, in his hardened form, was continuously attacked by Mashirao Ojiro's Tail, and with each hit, the strength and durability of his Quirk increased.[24]

Enhanced Durability: Eijiro's Quirk grants him greatly enhanced durability. His hardened body has displayed the ability to withstand a great deal of punishment for extended periods of time, including:

Several tons of scrap metal from a Villain Bot - Executor falling on top of him.[25] A number of point-blank explosions from Katsuki.[18] Bullets being fired at him.[12] A shower of blades produced by a villain whose blade Quirk was strengthened by Trigger.[19] A series of powerful punches from Kendo.[21] Chimera's full-power flame breath at point-blank range.[26] Dabi's flames burning his body.[27] Gigantomachia swiping him away.[27]

Enhanced Strength: When using his Quirk, Eijiro's physical strength is increased, enabling him to break through most obstacles. He demonstrated this multiple times during the Sports Festival, such as digging through debris from Villain Bots and defeating metal constructs.[25] In his arm-wrestling match against Tetsutetsu, his fingers dug through concrete, eventually breaking the podium.[17] He was also able to:

Break multiple concrete walls (alongside Rikido Sato) during a fight with Cementoss.[28] Shatter blades with a single elbow strike.[19] Destroy a concrete wall with help from Izuku.[20] Throw a punch strong enough to force Hekiji to block with a barrier.[21]

Ultimate Moves

Red Counter (烈レッ怒ド交吽咤カウンター, Reddo Kauntā?): While hardened, Red Riot endures a close-range attack and counters with a straight punch.[8] Red Riot Unbreakable transformation Unbreakable (安アン無ブ嶺レイ過武瑠カブル, Anbureikaburu?): Red Riot reaches his maximum hardening level by turning his entire body extremely rugged and jagged, giving him a monstrous appearance and practical invulnerability to most forms of physical attacks. This form can only be maintained for about 30–40 seconds.[8] Red Gauntlet (烈レッ怒ド頑ガン斗ト裂レッ屠ト, Reddo Gantoretto?): Red Riot charges the opponent and delivers a single, powerful punch to the gut. This move deals massive damage if used in his Unbreakable form.[29]

Kaina Tsutsumi

Alias: Lady Nagant Age: 38 Former Occupation: Pro Hero / Hero Public Safety Commission Assassin Current Status: Incarcerated at Tartarus Quirk Status: Rifle / Air Walk / Self-Destruct Quirk

Background

Kaina Tsutsumi, better known by her alias Lady Nagant, is a former Pro Hero and assassin who once worked directly under the Hero Public Safety Commission. Recognized as one of Japan’s most dangerous long-range fighters, she was secretly trained and utilized by the Commission to eliminate villains, criminals, and even corrupt heroes who threatened the carefully maintained image of Hero Society.

Although Kaina originally dreamed of becoming a genuine hero and protecting innocent people, her experiences working for the Commission gradually destroyed her idealistic outlook. She was repeatedly ordered to assassinate individuals without proper legal proceedings, forcing her to become accustomed to taking lives in the name of maintaining peace. Eventually, the hypocrisy and bloodshed behind Hero Society became too much for her to tolerate. After reaching her breaking point, Kaina killed one of her superiors and abandoned her position, becoming a criminal herself.

Following her arrest, Kaina was imprisoned in Tartarus, Japan’s most heavily secured prison. However, during the massive prison riot orchestrated by All For One and Tomura Shigaraki, she was released from her cell and eventually approached by All For One, who offered her a deal to hunt down Izuku Midoriya. Initially accepting the offer, she confronted Izuku but ultimately failed to capture him.

After being defeated by Izuku and witnessing his genuine determination to save others, Kaina began questioning her beliefs and eventually chose to stand against All For One. During the Final War, she willingly assisted the heroes, using her exceptional marksmanship to help Izuku during his battle against Tomura Shigaraki. However, she suffered severe injuries after All For One detonated the hidden self-destruct Quirk he had implanted within her body.

Following the Final War, Kaina was officially pardoned for her previous crimes. Nevertheless, she chose to remain incarcerated, having little faith in Hero Society and fearing that she might once again become a tool for those in power.

One month after the Final War, the Wildfire Virus outbreak began spreading throughout Japan. At the time, Kaina was still serving her sentence inside Tartarus and had never been released or returned to civilian life. As the infection began spreading across the country, the prison’s security and containment systems faced an unprecedented threat. With the outside world descending into chaos, Tartarus became an isolated stronghold filled with dangerous criminals, exhausted guards, and prisoners who had no idea what was happening beyond its walls.

Kaina remains incarcerated as the outbreak unfolds, with her future and chances of survival uncertain.

Appearance

Kaina is an attractive adult woman with a notably muscular yet curvaceous build. She has fair skin, gradient light-purple eyes with white pupils, thick eyebrows, and short, clumpy deep-indigo hair streaked with pink. Her hair is cut to chin length, with crooked frontal bangs that separate around the middle of her forehead and extend toward her shoulders in a distinctive side-tail hairstyle.

During her time as a Pro Hero, Kaina maintained a more youthful appearance, with her bi-colored hair grown considerably longer and tied into a high ponytail. Her bangs were thicker and more evenly arranged, and she wore a sleeveless, dark-colored, high-collared hero jumpsuit with navy-blue highlights. Her costume included protective green armor plates, matching knee guards, a large utility belt, and a blue scouter over her right eye.

Following her escape from Tartarus during the prison riot, Kaina abandoned the standard prison uniform and wore a dark-violet sleeveless turtleneck dress with a long, loose skirt. The outfit featured golden decorative details, a large garnet-colored utility belt, and several ammunition canisters attached to its sides. She also wore tall, pointed boots with black accents.

During the Final War, Kaina suffered catastrophic injuries after All For One detonated the hidden Quirk inside her body. The explosion left extensive scars across her face and body, and she required extensive medical treatment. Her body was covered in bandages, and she wore a blue hospital gown during her recovery.

At the beginning of the Wildfire outbreak, Kaina has not fully recovered from her injuries and still bears the scars left by the explosion.

Personality

Kaina is a serious, disciplined, and generally reserved woman who rarely expresses her emotions openly. She is direct, observant, and naturally intimidating, possessing a cold and stoic demeanor that developed through years of working as an assassin for the Hero Public Safety Commission.

She is not easily frightened or intimidated, even when confronted by extremely dangerous individuals. Her experience as an assassin has made her exceptionally composed under pressure, and she rarely allows emotions to interfere with her judgment. She is also sarcastic and occasionally displays a more casual, humorous side, particularly when interacting with people she trusts.

Beneath her hardened exterior, however, Kaina is a deeply disillusioned woman who has experienced considerable emotional suffering. She originally possessed an optimistic outlook and genuinely wanted to become a hero who protected others. Unfortunately, the Commission manipulated her ideals, turning her into an assassin who eliminated people behind closed doors while the public continued believing in the perfect image of Hero Society.

The repeated killings gradually destroyed her faith in the system she once served. Eventually, she became depressed and resentful, realizing that the peace she had helped maintain was built upon corruption, manipulation, and bloodshed. She grew particularly uncomfortable with the thought of innocent children admiring heroes without knowing the terrible things happening behind the scenes.

Although Kaina developed a cynical and pessimistic worldview, she never completely lost her desire to do what was right. Her encounter with Izuku Midoriya and Hawks reminded her of the genuine heroism she once wanted to represent. Despite her distrust of Hero Society, she eventually regained the courage to stand against All For One and help save others.

Kaina is also capable of recognizing the suffering of others, particularly those who have been manipulated or exploited by the very system meant to protect them. However, her compassion does not necessarily make her gentle. She can be ruthless when necessary and is willing to make difficult decisions if she believes they are justified.

Abilities

Exceptional Marksmanship: Kaina is widely considered Japan’s greatest long-range fighter. Her accuracy is extraordinary, allowing her to hit moving targets from distances of several kilometers. Even professional heroes with ranged Quirks struggle to match her precision and shooting ability.

Enhanced Eyesight: Kaina possesses exceptional eyesight, allowing her to identify and accurately target individuals from extremely long distances. Her marksmanship remains impressive even in darkness, heavy rainfall, and other unfavorable conditions.

Combat Experience: Years of training under the Hero Public Safety Commission have made Kaina an exceptionally skilled combatant and assassin. She possesses extensive knowledge of firearms, tactical positioning, stealth, tracking, and target elimination.

Enhanced Stamina and Endurance: Kaina possesses remarkable physical endurance, having survived severe injuries that would have killed most ordinary individuals. Even after suffering a massive explosion, she managed to remain conscious long enough to communicate vital information to the heroes. However, her injuries have left her physically weakened, and she has not completely recovered.

Quirks

1. Rifle

Kaina’s original Quirk allows her to extend a rifle from her right elbow, effectively transforming part of her arm into a living firearm. She loads ammunition through an opening in her palm and possesses an effective firing range of approximately three kilometers.

She can extend a tendril from the rifle and curl it into a makeshift scope, allowing her to improve her aim and target distant opponents.

One of the most unique aspects of her Quirk is her ability to pluck strands of her own bi-colored hair and mold them into ammunition. The hair can be twisted and shaped like putty before hardening into durable bullets capable of matching conventional ammunition. She can create different varieties of ammunition, including hollow-point and curving bullets. Certain bullets can even record her voice and replay messages after striking their targets.

Kaina can also increase the velocity and power of her shots by dramatically increasing the rifle’s output, although doing so risks causing the weapon to jam.

2. Air Walk

Air Walk is a secondary Quirk that Kaina received from All For One as payment for accepting his contract to capture Izuku Midoriya.

This Quirk allows her to levitate and move through the air, effectively allowing her to jump and maneuver without needing solid ground beneath her feet. She primarily uses it alongside Rifle, allowing her to change sniping positions, attack from unexpected angles, and pursue targets while airborne.

3. Unnamed Self-Destruct Quirk

An additional Quirk secretly implanted within Kaina’s body by All For One as a contingency should she ever betray him.

This Quirk allows All For One to remotely trigger a massive explosion within Kaina’s body, causing devastating internal and external damage. He secretly installed it without informing her, intending to eliminate her if she ever changed her mind about working for him.

During the Final War, All For One activated this Quirk, leaving Kaina severely injured and covered in scars. Despite surviving the explosion, she has never fully recovered from the damage it caused.

Wildfire Virus The Wildfire Virus is a highly contagious and extremely dangerous pathogen that transforms its victims into reanimated, aggressive, and predatory beings. Once inside a living host, the virus begins spreading rapidly throughout the bloodstream, gradually taking control of the body's biological systems until the victim eventually succumbs to the infection. However, death is not the end of the process. After killing its host, the virus reactivates the deceased body, turning it into an infected creature that actively seeks out living humans and other potential hosts. Transmission and Contagion: The Wildfire Virus spreads through direct contact with infected bodily fluids. Its primary methods of transmission are bites, scratches, and exposure to infected blood or saliva. A bite introduces contaminated saliva directly into the victim's bloodstream through broken skin, while scratches can transmit the virus when infected bodily fluids enter an open wound. Direct exposure to infected blood or saliva can also cause infection if the fluids come into contact with an individual's bloodstream, open wounds, or mucous membranes. The virus does not spread through ordinary airborne transmission, meaning simply being near an infected individual does not automatically result in infection. However, any physical confrontation with an infected individual carries a significant risk of exposure. Infection and Progression: Once the Wildfire Virus enters the body, it begins multiplying rapidly and spreading through the victim's bloodstream. Initially, the infected individual may experience little to no noticeable symptoms, but this changes as the virus gradually overwhelms their biological systems. The most prominent early symptom is a severe fever that persists for several days, accompanied by physical weakness, headaches, fatigue, disorientation, and a gradual deterioration of the victim's overall health. As the infection progresses, the virus begins attacking vital organs and disrupting normal bodily functions. Eventually, the victim's organs begin shutting down, resulting in complete biological death. Following the victim's death, the virus enters its final stage. Rather than allowing the body to remain deceased, it reactivates the host's motor functions and takes control of the body, effectively reanimating the individual. The infected individual is no longer biologically alive, but the virus continues operating the body, transforming it into a dangerous and aggressive predator. Physical Enhancements: Reanimated hosts experience significant physical enhancements compared to their former living selves. Their strength and speed increase considerably, allowing them to overpower and pursue living individuals with frightening efficiency. Their movements become more aggressive and unpredictable, and they can continue functioning despite injuries that would normally incapacitate an ordinary human. Their bodies are no longer restricted by the same physical limitations or instincts for self-preservation that governed them while alive. However, their physical condition can still deteriorate over time as their bodies continue to decay. Intelligence and Mental Deterioration: Unlike traditional zombies, Wildfire-infected individuals retain fragments of their original intelligence, memories, instincts, and awareness after reanimation. They are not completely mindless creatures. Depending on the individual, an infected host may recognize familiar faces, remember certain locations, display recognizable habits, and retain fragments of their former personality. They may even demonstrate basic problem-solving abilities and react to familiar surroundings. However, their intelligence is severely compromised and gradually deteriorates the longer they remain infected. Newly reanimated individuals retain significantly more of their original mental capabilities, making them capable of recognizing people they once knew and displaying occasional behaviors reminiscent of their former selves. As time passes, their memories become increasingly fragmented, their ability to reason deteriorates, and their behavior becomes more primitive and instinct-driven. Eventually, most infected individuals lose the majority of their remaining intelligence, becoming increasingly aggressive, unpredictable, and driven primarily by their instincts to hunt, feed, and spread the infection. Despite this deterioration, certain memories, habits, and instincts may persist even in older infected individuals, making their behavior occasionally unpredictable. Quirk Retention and Degradation: One of the most dangerous characteristics of the Wildfire Virus is its ability to preserve a host's Quirk after reanimation. Infected individuals retain access to the Quirks they possessed while alive, allowing them to continue utilizing their supernatural abilities even after death. However, the virus interferes with the host's neurological functions and ability to properly control their Quirk. As a result, their abilities become less effective, less precise, and significantly harder to regulate than they were before infection. For example, an infected individual with an explosive Quirk may still produce explosions but struggle with accuracy and control. Someone with an ice or fire-based Quirk may retain the ability to generate their respective elements but have difficulty regulating their output. Other infected individuals may experience unstable or unpredictable manifestations of their abilities. The effectiveness and control of an infected individual's Quirk depend on the nature of their original ability and how severely the infection has affected their body and mental functions. Overall Behavior: Wildfire-infected individuals are predominantly hostile toward living organisms. Their primary instincts revolve around hunting living humans, attacking potential victims, and spreading the infection through bites, scratches, and bodily fluid exposure. Although they retain fragments of their former intelligence and memories, these remnants gradually disappear as the infection ages. Their enhanced physical capabilities, retained Quirks, and fragmented intelligence make them considerably more dangerous than ordinary reanimated corpses. The most disturbing aspect of the Wildfire Virus is that its victims do not immediately lose every trace of who they once were. Beneath the aggression, deteriorating memories, and predatory instincts, fragments of their former identities may still remain.

Meteor Wildfire — Origin of the Wildfire Virus

The origin of the Wildfire Virus can be traced back to an unusual meteor that suddenly appeared in Earth’s atmosphere. The meteor resembled a massive object engulfed in flames as it descended through the sky. Its origin was completely unknown, and initial examinations revealed the presence of strange, previously undiscovered minerals embedded within its surface. These minerals had never been documented or encountered by scientists before.

Without warning, the meteor suddenly altered its trajectory and crashed into a remote mountainous region of Japan. Fortunately, the impact did not result in any immediate human casualties due to the isolated location of the crash site. However, the surrounding wildlife was exposed to the unknown substance released from the meteor. Nearby animals became contaminated, unknowingly carrying the foreign pathogen within their bodies.

Interestingly, the infected animals did not develop the symptoms or undergo the transformations associated with the Wildfire Virus. Instead, they became carriers of the infection without showing any apparent signs of illness. As these animals continued moving through their natural habitats, they eventually came into contact with humans, unknowingly transmitting the pathogen through bites, scratches, and contaminated bodily fluids.

Once the virus began infecting humans, its devastating effects became apparent. The infection spread rapidly throughout the population, overwhelming communities, hospitals, emergency services, and eventually the country’s entire infrastructure. Within only a few months, Japan had fallen to the outbreak, with infected individuals vastly outnumbering the remaining survivors.

In response to the catastrophe, Japan was placed under an extreme nationwide quarantine. International authorities established a complete containment perimeter around the country, prohibiting anyone from entering or leaving Japanese territory. All travel, transportation, and international crossings were suspended in an attempt to prevent the infection from spreading beyond Japan’s borders.

Japan had effectively become a sealed-off quarantine zone, abandoned to the growing outbreak within its borders.
