Face Claim/Appearance:
“My name is Yoshikage Kira. I'm 33 years old. My house is in the northeast section of Morioh, where all the villas are, and I am not married. I work as an employee for the Kame Yu department stores, and I get home every day by 8 PM at the latest. I don't smoke, but I occasionally drink. I'm in bed by 11 PM, and make sure I get eight hours of sleep, no matter what. After having a glass of warm milk and doing about twenty minutes of stretches before going to bed, I usually have no problems sleeping until morning. Just like a baby, I wake up without any fatigue or stress in the morning. I was told there were no issues at my last check-up. I'm trying to explain that I'm a person who wishes to live a very quiet life. I take care not to trouble myself with any enemies, like winning and losing, that would cause me to lose sleep at night. That is how I deal with society, and I know that is what brings me happiness. Although, if I were to fight I wouldn't lose to anyone.”Canon:

Personality: Kira is a serial killer, characterized as highly egocentric and psychopathic, with a few obsessive-compulsive tendencies. He is also a hand fetishist.
Kira longs for a peaceful and quiet life, safe from any worry, and does not wish for it to be interrupted. Whenever that life seems assured, Kira adopts a jolly and confident demeanor. Although he is highly intelligent and possesses many talents, this yearning shows in his dislike of coming in first, and Jotaro theorizes from his many trophies that he even made it a point to never rank better than 3rd in any competition so as not to stand out. Since his youth, Kira has been avoiding standing out, living a healthy life and following a strict regimen. He becomes bothered when someone disrupts his habits and goes to extreme lengths to get them back. As his father pointed out, this will to stay in the background was so bad that if bullied, or denied his favorite toy, Kira would bite his nails until they bled, being the only way he's found to express his frustration.
However, beneath his façade of a simple, humble salaryman, Kira is very abnormal. The most abnormal characteristic of Kira is his frequent and periodic murderous impulses. Kira targets women, or, more specifically, women with beautiful hands. Kira possesses a hand fetish, which he discovered when he found himself aroused by the Mona Lisa's hands. However, his desire has never extended to the rest of the female person and he otherwise shuns their presence. This results in murdering random women, not caring in the least how they look like or behave, in order to acquire their (severed) hands as "girlfriends", acting as if the severed hands were actually sentient and conversing with them, even offering them various gifts. When one "girlfriend" begins to decay, he disposes of it and goes off in search of a replacement. Kira is an opportunistic killer, his modus operandi being spotting a potential victim, following her to her house, and murdering her when both are isolated. His Stand erasing any proof, these murders are actually reported as missing persons. Moreover, Kira has expressed various other similarly violent impulses such as the desire to choke his victims to death and has horribly scarred at least Reimi Sugimoto.
Apart from his murders, Kira is particularly violent when someone threatens his way of life or publicly humiliates him. Since Kira doesn't want to be noticed, he will try everything to solve his problems without facing anyone directly. However, if he doesn't have any other choice, he will instantly try to kill whoever discovers his true nature. Kira is quick to drop his polite demeanor, rudely insulting his foes or violently beating them before killing them. After Koichi's Echoes ACT 3 results in Kira making a fool of himself in public and attracting unwanted attention, Kira went on his way to torture and humiliate Koichi, putting his shoe into his mouth and slamming his face against the ground. Kira has a hard time controlling these impulses, as seen when Hayato Kawajiri threatened to blackmail him. Kira lost his calm attitude and murdered him despite knowing he couldn't afford such a mistake.
Kira is also afflicted with a number of other quirks. Apart from his wish for a monotonous and tranquil life, Kira's OCD also makes him very meticulous and thorough. Kira has sophisticated tastes, notably buying his lunch at the best store in town as well as wearing Valentino suits. He doesn't tolerate any imperfection and is even willing to lose time fixing Koichi's socks, becoming agitated when he sees them being worn inside-out. Furthermore, during his time as Kosaku Kawajiri, Kira made sure to perfectly mimic his new identity in every way, notably Kosaku's hand-writing, which he trained himself to do conscientiously. Kira's solitary nature is partially stemmed from his disgust of people who don't behave as properly as he does.
Kira is also an egocentric and selfish man, akin to a spoiled child. He doesn't care that his lifestyle involves murder, nor the suffering of his victim's relatives. He only seeks to satisfy his basic instincts. In addition, Kira is determined to preserve his lifestyle, and being set back only increases his determination. Kira is also quick to shift the blame to someone else for his troubles, notably the Joestar group, for ruining his life. Kira possesses a twisted pride in having managed to mix his tranquil lifestyle and his serial murders for so long, and categorically refused to flee the town and live in fear, preferring to maintain a shaky façade of normal life with the Kawajiri's.
In addition, while normally a very cautious meticulous man who ensures he leaves no evidence behind, there are a few occasions where he becomes overconfident and lets his guard down, and each time has led him to a confrontation with the Joestar group or defeat at their hands. He once put his "girlfriend hand" in a sandwich bag and failed to notice Shigechi's presence as he came to take the sandwich bag, thinking it was his. This would lead him to his first confrontation with the Joestar group. In addition, he left his jacket to a tailor at Centipede shoes and left his real name, forcing him to confront them. He was overconfident in his Sheer Heart Attack, believing it was invincible and leaving the scene, but was forced to return to the scene of his crime when Koichi managed to subdue Sheer Heart Attack. In addition, he let his guard down near a wounded Jotaro, allowing Jotaro the opportunity to beat him. Finally, when he was overconfident he had beaten Hayato Kawajiri in his attempt to stop him, he blurted out his real name in front of Josuke by mistake, which Hayato had planned.
Kira believes that he has luck and fate on his side, exposing a superstitious façade, claiming that whenever faced with an obstacle he will be able to make it through with a combination of hard work and opportunity. He measures and collects his own fingernail clippings, using them to predict his murdering luck off of their length.
When Kira was pierced with the Arrow, his demeanor became much more relaxed and prone to elation due to his new-found power, which guaranteed that anyone approaching Hayato would be killed. Ecstatic to possess a power which would dispose of anyone who investigated him, Kira allowed himself one loud boast, which caused his downfall as Josuke overheard him claiming to be "Yoshikage Kira".
During his confrontation with the Stand Stray Cat, Kira expressed a desire to protect his "wife", Shinobu Kawajiri, and even showed relief at her safety. A feeling that confused him, and Kira rationalized it as him merely not wanting to arouse suspicion. Whether these feelings were genuine or not is left unanswered.
Equipment: Yoshikage Kira himself rarely engages in combat, relying on his Stand for most engagements. As a result, he does not carry much equipment on his person.
Attributes: Yoshikage Kira wields the Stand
Killer Queen.
Killer Queen is a short-range humanoid Stand of average to above-average speed and melee attacking power. Although it is undeniably physically powerful, it is overshadowed by other close-range Stands like Crazy Diamond and Star Platinum, and thus Kira relies more on evading his enemies or using Killer Queen's set of powers to prevail.
Killer Queen's powers revolve around setting up different kinds of bombs that can annihilate Kira's enemies in one blast, making it a very dangerous Stand to face. Not only are the bombs powerful, but Kira is also able to deploy two initially, then eventually three kinds of bombs with different strengths, giving the serial-killer a large array of options when dealing with his foes.
Bomb TransmutationKiller Queen may charge any object, inanimate or not, as a bomb simply by touching it.
Once a target has touched the object, Killer Queen can detonate the target by pressing its right thumb onto a trigger located on its index fingers middle phalanx, imitating the action of pressing down on a handheld detonator; the charge immediately travels through the target's body before exploding. Additionally, Killer Queen can blow up the charged target itself, as demonstrated with Stray Cat's air bullets during the final battle with Josuke Higashikata; however, if someone else touches the charged target before Kira can detonate it, they will automatically be blown up instead, consuming the charge. This can also be done through direct contact with Killer Queen or Kira himself, skipping the charging process. The charge is so powerful that it is capable of destroying a unit of Harvest, a Colony Stand capable of dividing itself upon taking damage, that greatly injured Shigechi.
Matching Kira's desire to keep his murderous life a secret, anyone detonated by Killer Queen is completely incinerated with their body, their clothes and any personal belongings they were carrying being completely vaporized at the atomic level, leaving no trace; however, it is possible for a victim to survive an explosion if it comes from a nearby object instead of their own body, though this is a rare occurrence. Kira can also control the size and strength of Killer Queen's explosions as well as what parts of a victim's body are vaporized, usually resulting in Kira destroying his victim's body except for their right hand to keep. The effects of Kira's explosions on their surroundings vary; they generally do not damage nearby walls and floors, but during Kira's battle with Josuke, they could potentially affect nearby objects and Kira himself, though this may be due to Stray Cat's own Stand power being combined with Kira's.
There are several limitations to this ability. First, if Kira or Killer Queen cannot press their thumb against their index finger's middle phalanx to trigger the bomb's detonation, the target cannot blow up. In addition, since this power is similar to incendiary bombs, it also cannot induce their explosions if there is no air, as demonstrated by Stray Cat disabling a bomb by creating a vacuum around it. Finally, Killer Queen can only charge one object at a time.
It is unknown if non-Stand users can see or feel the explosions, but they can see a victim of an explosion die. Additionally, the explosion does not seem to generate much sound to anyone other than the victim, as Josuke and Okuyasu heard Shigechi call out to Josuke just outside of their classroom, but neither of them were aware of the ensuing explosion. Additionally, there were at least two other students in the same hallway as Shigechi when he was killed, but neither seemed to be aware of his demise as their backs were turned to him when he was killed and all evidence of an explosion dissipated within less than a few seconds.
Air Bomb TransmutationDuring the final battle, Kira places Stray Cat in Killer Queen's hollow abdomen. With Killer Queen's Primary Bomb charging Stray Cat's condensed air bubbles, Kira may create virtually invisible air bombs to use as projectiles. These can be detonated automatically through contact or manually through Killer Queen's switch. Although he also cannot see these bombs, Kira is skilled in determining their trajectory using basic mathematical skills; additionally, Yoshihiro Kira can verbally help him direct his aim by flitting about the battlefield in his photograph form. Due to Stray Cat not being readily available in this setting, Kira will very likely have no way to employ this ability.
Sheer Heart AttackSheer Heart Attack is Killer Queen's second type of bomb, featured primarily in the arc Sheer Heart Attack.
This treaded automatic bomb detaches from Killer Queen's left hand, so any Stand abilities activated upon it are reflected onto Kira's left hand. Because Sheer Heart Attack is attached to Kira's left hand, the primary bomb can still be used when Sheer Heart Attack is active.
It is completely autonomous and has a great range, so Kira can safely engage Sheer Heart Attack and move a great distance away while it carries out its duties. It seeks out whatever the warmest object in the vicinity is, even changing targets the second a warmer object appears; upon reaching its target, it automatically induces an explosion with power and blast size equivalent to the heat of the target. If Sheer Heart Attack's explosion was set off by a non-human source, it will continue to seek out targets until it explodes from a human. Like Killer Queen's first bomb, Sheer Heart Attack's explosions remove all physical evidence of the target.
The body of Sheer Heart Attack is nigh-indestructible, withstanding countless blows from Jotaro's Star Platinum, but can still be affected by non-damaging Stand powers and cracked if pulled apart at the mouth with tremendous force.
Its main drawback lies in its autonomous nature, which will sometimes prevent Sheer Heart Attack from prioritizing killing Kira's intended human target(s). Secondly, since it needs to explode from making contact with a human target to fully dissipate, should Sheer Heart Attack need to be deactivated while actively seeking a target, the user must physically return in the range of Sheer Heart Attack to deactivate and retrieve it. Furthermore, Sheer Heart Attack can continue to be active even after Kira's hand has been cut off, seen when he uses this to escape Josuke and company. Cutting off his hand even gives Sheer Heart Attack more power, as well as the ability to withstand even Echoes ACT 3's 3 Freeze.
Killer Queen Bites the Dust Killer Queen Bites the Dust is Killer Queen's third type of bomb, featured primarily in the arc Another One Bites the Dust.
Kira is granted this ability when Yoshihiro Kira's Stand-creating Arrow pierces him a second time. It is born from Kira's desire to prevent anyone from knowing his true identity, as well as his desperation following his impulsive murder of Hayato Kawajiri. Many fans debate if Bites The Dust is considered a Requiem Stand, as it shares the same characteristics.
This bomb appears as a miniaturized form of Killer Queen that hides inside whoever it is planted in; it acts independently of Kira's will, manifesting only when the bomb is triggered. When planted in Hayato, it activates when Kira's identity is revealed audibly or through writing, as well as when other Stand users see the miniature Killer Queen. When this happens, a miniature Killer Queen enters the eye of the person and causes an explosion, killing them. The bomb can detonate multiple people simultaneously. After killing someone with its power, Bites the Dust creates a temporal loop, rewinding time to roughly one hour prior to the detonation. Because Bites the Dust is completely independent and autonomous, Kira is not aware of who is killed by it, nor is he directly aware of whether a time loop has taken place. In fact, the only person who retains the memory of each time loop is the person harboring Bites the Dust. All actions performed in the previous time loop are destined to occur as they had happened. Slight deviations may happen, but any person killed by Bites the Dust in a previous time loop is destined to explode at the exact time that they were previously killed, even if they did not re-activate Bites the Dust in the current timeline.
Because the person in whom the bomb is planted must be alive in order to activate the trigger, Bites the Dust will never harm the person with its explosions nor let them be harmed by other forces, demonstrated when the miniature Killer Queen prevented Hayato from slitting his own throat with a knife to prevent anyone else from dying. Ironically, Bites the Dust also prevents the Stand User themselves from harming the bomb's carrier, with the miniature Killer Queen intercepting Kira's fist when he tries to punch Hayato. It also appears to be able to revive that person if they are dead when it is activated, as Hayato was alive once more when Kira planted it in him after impulsively killing him, implying that time was looped to prevent Hayato from dying again the same way.
The only way to stop Bites the Dust's effects is to outright kill Kira or otherwise force him to withdraw it; should this occur, all timelines created using Bites the Dust are erased. Additionally, using Bites the Dust forcibly prevents Kira from activating any of Killer Queen's other abilities because Killer Queen is planted in the body of the third party; thus, he must deactivate Bites the Dust and withdraw Killer Queen if he needs to defend himself. Hayato also deduces that Bites the Dust only works on non-Stand users, as Kira can only tell a non-Stand user his secrets to enable the ability.
