Unnoticed in Morioh for years and undisturbed all his life, Yoshikage Kira is an abnormal and paraphilic serial killer whose murderous routine is shaken when the ghost of his first victim, Reimi Sugimoto, begs the living to look for him. Upon attracting unwanted attention by killing Shigekiyo Yangu, Josuke and the others sets their sights on Kira in order to put an end to his killing spree.
Kira is a Stand user and wields the powerful Killer Queen to create deadly bombs.
Yoshikage Kira has a medium build and average height.[3] He has light hair, loosely combed with a few strands out of place. He wears a light Valentino[8] suit and a dark tie patterned with a column of skull emblems featuring upright, cat-like ears, similar to those on his Stand, Killer Queen, as well as on Sheer Heart Attack. As a salaryman by profession, he wears a similar suit throughout the series, though he usually takes off his jacket at home.
Kira adopts one face other than his original one in Part 4, and a ghostly body resembling his original, with a unique outfit, after this. He remains a man of average height and slim to athletic build.
When Kosaku Kawajiri is killed, Kira assumes his facial features, including his spiky black hair, thin, large dark irises, and higher cheekbones. He retains his suit, changing only his tie to his normal Skull tie.
After being hit by the Arrow and receiving Killer Queen's third bomb, Kira's hairstyle spontaneously changes, becoming perfectly combed back, light, and striped by black strands.
Shortly after he dies, as a ghost, he retains Kosaku's features for a few moments before reverting to his original appearance, which he retains in Deadman's Questions. Henceforth, he adopts an elaborate outfit consisting of a dark bowler hat with an upturned brim and a tie, both patterned by concentric squares, and a shirtless, dark, lapelless suit.

Personality
“
I really want to reveal Yoshikage Kira's true nature to that girl on the right. I'd like to reveal my deep desires to her. I really want to touch her thin neck with my hands... and strangle her to death.
Kira is a serial killer, characterized as highly egocentric and psychopathic, with a few obsessive-compulsive tendencies. He dislikes any changes in his daily physical condition or routine. He takes the same route every day, puts on his clothes in the same order, and eats at the same time and in the same sequence. He is also a hand fetishist.[3]
Kira enjoying his lunch time and appreciating Morioh's beauty
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.[9][10] 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.[5] Since his youth, Kira has been avoiding standing out, living a healthy life, and following a strict regimen.[7] He becomes bothered when someone disrupts his habits and goes to extreme lengths to get them back. As his father pointed out, his obsession with staying in the background was so intense that if bullied or denied his favorite toy, Kira would bite his nails until they bled, being the only way he could express his frustration.[11]
Beneath his facade of a simple, humble salaryman, Kira is very abnormal; his most abnormal characteristic being his frequent and periodic murderous impulses. Kira targets women, or, more specifically, women with beautiful hands. He possesses a hand fetish, which he discovered when he found himself aroused by the Mona Lisa's hands.[12] However, his desire has never extended to the rest of the female person and he otherwise shuns their presence.[9] This results in murdering random women, not caring in the least how they look or behave, to acquire their severed hands as "girlfriends". He acts as if the severed hands are sentient and converses with them, even offering them various gifts.[13] When one "girlfriend" begins to decay, he disposes of it and goes off in search of a replacement.[9] 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.[14][15] Due to his Stand leaving no trace of their victim behind, these murders are reported as missing persons. Moreover, Kira has expressed various other similarly violent impulses such as the desire to choke his victims to death[16] and has scarred at least Reimi Sugimoto.[17]
Kira slamming Koichi's face into the pavement
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.[7] Kira is quick to drop his polite demeanor, rudely insulting his foes or violently beating them before killing them. After Koichi's Echoes ACT3 results in Kira making a fool of himself in public and attracting unwanted attention, Kira goes on his way to torture and humiliate Koichi, putting his shoe into his mouth and slamming his face against the ground.[18] Kira has a hard time controlling these violent impulses, as seen when Hayato Kawajiri threatened to blackmail him. Kira lost his calm attitude and murdered Hayato in an enormous lapse in judgment.[11]
Kira is also afflicted with several 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[9] as well as wearing Valentino suits.[8] He doesn't tolerate any imperfection and is even willing to waste time fixing Koichi's socks instead of fleeing the scene, as he could not stand seeing them being worn inside-out.[18] Furthermore, during his time as Kosaku Kawajiri, Kira made sure to perfectly mimic his new identity in every way, notably Kosaku's hand-writing,[16] which he trained himself to do conscientiously. Kira's solitary nature is partially stemmed from his disgust with people who don't behave as properly as he does. Kira's favorite fashion brand is Gianfranco Ferré.[2]
Kira utterly determined to preserve his "peaceful life"
Kira is also an egocentric and selfish man, akin to a spoiled child. He doesn't care that his crimes involve murder and make his victim's relatives suffer. 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 Josuke and his allies, for ruining his life.[16] 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.[11]
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 Josuke and the others or defeat at their hands. He puts his "girlfriend's" hand in a sandwich bag and fails to notice Shigechi's presence as Shigechi comes to take the sandwich bag, thinking it is his,[9] which eventually leads to Kira being found out. In addition, Kira leaves his jacket with a tailor at Centipede Shoes alongside his real name, forcing Kira to confront Jotaro and Koichi.[19] He is overconfident in his Sheer Heart Attack by believing it is invincible and leaves,[20] but is forced to return to the scene of his crime when Koichi manages to subdue Sheer Heart Attack. In addition, he lets his guard down near a wounded Jotaro, allowing Jotaro the opportunity to beat him.
After getting Bites the Dust, Kira becomes extremely confident
After being pierced with the Arrow a second time, Kira's demeanor becomes much more relaxed and prone to elation due to his new-found power, which guarantees that anyone approaching Hayato Kawajiri would be killed. When he is overconfident he has beaten Hayato in his attempt to stop him, Kira blurts out his real name in front of Josuke by mistake, which Hayato had planned.[21]
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 fingernail clippings, using them to predict his murdering luck off on their length.[5]
During his confrontation with the Stand Stray Cat, Kira expresses a desire to protect his "wife," Shinobu Kawajiri, and even shows relief at her safety. The feeling confuses him, but Kira rationalizes it as simply not wanting to arouse suspicion.[22]
As a ghost, Kira loses all memory of his previous life, including his temptation to kill. However, his desire for a peaceful existence and his latent brutality remains.[23]
Kira's Stand, Killer Queen, is a humanoid, short-range Stand with the unique ability to cleanly, and completely, wipe out objects and people alike with targeted explosions. This ability manifests itself as three distinct forms, or 'bombs'.
Bomb Transmutation (Primary Bomb): Killer Queen can charge any object into a bomb simply by touching it. The Stand can then manually detonate the charged object, causing powerful explosions.
Sheer Heart Attack (Secondary Bomb): Sheer Heart Attack is an autonomous entity that detaches from Killer Queen's left hand. It is a mobile, heat-seeking bomb that is extremely durable and leaves massive explosions in its wake.
Killer Queen Bites the Dust (Tertiary Bomb): Created by a second pierce of the Arrow, Bites the Dust is an independent bomb that implants Killer Queen into a host body. If the host reveals Kira's true identity in any way, willingly or unwillingly, Bites the Dust will trigger, and any investigators will be blown up before a time loop commences that sends everyone back an hour. Kira is unable to use this ability on himself, however.
Killer Queen changes an air bubble into a primary bomb
After gaining Bites the Dust, Kira keeps Stray Cat in a hollow space within Killer Queen's abdomen. With Killer Queen's Primary Bomb charging Stray Cat's condensed air bubbles, Kira may create invisible, speedy air bombs (空気弾, Kūki-dan) to use as projectiles. Although no one, not even Kira, can see these bombs, the latter is skilled in determining their trajectory using basic mathematical skills.
Despite the power of his Stand, Killer Queen, Kira's passivity led to an over-reliance on its powers to the detriment of actual mastery.
Up until his appearance, Kira has avoided fighting at all, leading to a laissez-faire approach to Stand battles. Although he did personally kill Shigekiyo Yangu and knows a great deal about the subtleties of Killer Queen, he then let Sheer Heart Attack take care of two Stand Users, leading to an unexpected defeat and almost leading to his capture. He then became overconfident in Bites the Dust's invincibility, again leaving ample opportunity for Hayato to seek a loophole. Kira's tendency to hide and avoid instead of confronting his foes has left him no time to show any imagination in using his Stand.
However, thanks to his intellect and "lucky" meeting with Stray Cat, Kira could sublimate Killer Queen's power to create a deadly long-range combination of Stand abilities.
Relationships
Family
Yoshihiro Kira: Yoshihiro is protective of his son, enough so that he was willing to support his son's murderous streak without a care as long as it made him happy. However, Yoshikage thought little of his father, ignoring his advice of leaving Morioh and sparing no thought for him when he died. In the end, Yoshihiro died in the most ironic way possible, being blown up by his son's bomb after he was tricked by Josuke into doing so.
Mother: While little is known about their relationship and Kira's opinions of her, Araki points out that her overall appearance, as presented in their family portrait, suggests she may have been a bit overprotective of Kira to a point of abusive coddling.[1]
Kawajiri Family
Shinobu Kawajiri: While Kira impersonated Kosaku, his failed attempts at acting ordinary were mistaken by Shinobu for a change toward a bolder demeanor from her husband. Charmed, Shinobu became attracted to her husband, not knowing that it was Kira. Kira on the other hand first struggled not to act on his murderous impulses on Shinobu and tried his best not to attract attention, thus acting gently with her. As time passed, notably after protecting her from Stray Cat, Kira noted a burgeoning affection for her.
Hayato Kawajiri: Hayato and Kira lived in mutual suspicion, with Hayato noting everything his "father" did that was out of the ordinary, while Kira disliked the company of such a nosy child. When Hayato hears Kira plotting to kill him and then sees him use Killer Queen to kill a couple, their relationship turns antagonistic, culminating in Kira killing Hayato in a fit of rage. When Hayato becomes the catalyst for Kira gaining the sub-bomb Bites the Dust, Kira underestimates Hayato's resourcefulness, dismissing him as harmless at first, which Hayato exploits to lure Kira into the hands of his enemies. Hayato had come to know Kira well and proved a useful source of information during the climactic fight between Josuke and Kira.
Tama: Kira and the cat Tama were initially enemies due to Kira's interference in Stray Cat's revenge against Shinobu. Kira wanted to get rid of the conscious plant as it was likely to attract attention, but after distracting it, he decided to keep Stray Cat in the attic, planning to use it later. During his confrontation with Josuke, Kira made the most of Stray Cat's power by combining it with Killer Queen's detonation ability to produce air bombs.
Enemies
Josuke Higashikata: After Shigechi had been killed, Josuke developed a grudge against Kira and swore to avenge Shigechi. While Josuke loathed Kira, the latter didn't think much of Josuke and as an enemy, preferred to avoid any confrontation with him. However, Kira noticed that Josuke's healing power and resourcefulness countered his Killer Queen's bomb power and was precautious against him during their fight.
Rohan Kishibe: Rohan was at first only curious about the local murderer, but after learning that he almost died by his hand and that Reimi protected him, his efforts for finding Kira became more personal. As an enemy, Kira preferred to avoid any confrontation with him. He was also aware of Rohan's status as a famous mangaka. When Rohan fell victim to Bites the Dust, Kira took great joy in his death.
Koichi Hirose: Koichi, after learning of Kira's crimes, came to deeply loathe him to the point he would attack him on sight. Kira, on the other hand, came to somewhat praise Koichi's ability for being able to track him and then indirectly humiliate him in public, which he made sure to pay back with a beating. When Koichi humiliated Kira a second time, demonstrating how careless the serial killer could be, Kira was enraged and came to detest Koichi, being happy at the prospect of Koichi dying.
Okuyasu Nijimura: Okuyasu, after learning that Kira killed Shigechi, developed a deep grudge against the murderer. As an enemy, Kira preferred to avoid any confrontation with him. During Josuke and Okuyasu's fight with him, Kira used Stray Cat to incapacitate Okuyasu and turned him into a bomb to trick Josuke into healing him. In the midst of attempting to kill Josuke with an air bomb, Kira was surprised when Okuyasu suddenly came back to life and not only saved Josuke, but separated Stray Cat from Killer Queen.
Jotaro Kujo: The first time Jotaro would encounter Kira was near the Centipede shoe shop after Jotaro was heavily wounded by Sheer Heart Attack. Kira underestimated Jotaro due to the poor state he was in, only to get pummeled by Star Platinum for his trouble. Kira noted how dangerous Jotaro was and took care to avoid confronting him again. While confronting Hayato in the second Bites the Dust loop, Kira mentions to him that he would be very happy if Jotaro were to die in particular.
Victims
Reimi Sugimoto: Reimi was the first victim of Yoshikage Kira fifteen years prior to the start of Part 4 along with the rest of her family, including her pet dog Arnold. As a ghost, Reimi remained in Morioh, looking for someone to help her put a stop to Kira's murders in order to restore Morioh's peace and dignity. While Kira managed to remember her name when Shigekiyo mentioned her, he couldn't recognise her at first when they met fifteen years later, which Reimi theorizes as Kira not having the occasion to remember her since he didn't take her hand as a "girlfriend". After her archenemy was dragged away by the ghost hands of the alleys, Reimi was able to peacefully ascend to heaven.
Arnold: Arnold's throat was slashed by Kira fifteen years prior to the start of Part 4. Kira then hung the dog's body on a clothes hook in the wall. Upon Kira's death, Arnold took his revenge by forcing Kira to look behind him, condemning the killer to be dragged away by the ghost hands. Now at peace, his soul ascends to Heaven along with his owner Reimi.
Shigekiyo Yangu: When Shigechi unwittingly took Kira's "girlfriend", Kira saw Shigechi as a potential threat to his peaceful lifestyle. When both confronted each other, Shigechi realized that Kira was a serial killer after finding his "girlfriend" and immediately prepared to kill him. On the other hand, Kira thought little of Shigechi, seeing him as a hindrance to his quiet life and wanting to dispose of him as soon as possible. Learning that Kira will kill his family too after being seriously injured, Shigechi tried to warn his friends Josuke and Okuyasu to protect them, only to be caught and killed by Kira. Shigechi's death alerted the Stand users of the serial killer, and thus became the source of Josuke and Okuyasu's grudge towards Kira.
Mukade Shopkeeper: While the two never interacted onscreen, Kira and the shopkeeper knew each other well as the former is a customer at the latter's store. Despite this, Kira had no compunction silencing the shopkeeper with Sheer Heart Attack once Jotaro and Koichi entered the store to find the killer's identity.
Aya Tsuji: The two had little interaction, but Kira was aware of her occupation and abilities, which allowed him to escape the protagonists and change his identity. Before being killed by Kira, Aya described him as truly terrifying and hated him for using her powers for evil.
Kosaku Kawajiri: The two had no onscreen interaction and Kira only accosted him because they were of similar height and build. He kidnapped Kosaku, dragged him to Salon Cinderella, killed him, and took his identity including his face, fingerprints, and hair. Kira, however, was annoyed by Kosaku's willingness to have a promotion, forcing Kira to stress himself by bootlicking Kosaku's superior while having to impersonate him in order to maintain his masquerade.
Minako Okura and Satoru Nakae: Initially, Kira, as Kosaku, had no interest in the couple, only to be insulted by them for moving Minako's bag away from his leg, and then for his nail clippers after bumping into them. Incensed, Kira stalked the two and barged into their apartment, greeting Satoru by detonating him and intimidating Minako into giving him her name and cutting his fingernails. After giving her Satoru's ears as earrings to wear, Kira vaporized Minako besides her hand to keep as his "girlfriend". Ironically, this act caught the attention of his "son" Hayato, who filmed the scene on tape.
Post-mortem
Female Monk: In Deadman's Question, Kira's ghost works as a hitman for a female monk. Their relation is strictly professional and he only kills whoever the monk points him to in order to earn money. Kira is shown to be a bit suspicious and dismissive of the monk, calling his job doing her dirty work, while the monk is neutral with Kira. After Kira escapes the Cleansers of the mansion ghost, Kira suspects she was trying to eliminate him and thus he goes to investigate her claims about the mansion ghost to make sure she was not leading him into a trap, planning to kill her if it turns out she was lying.
In over 15 years, I, Yoshikage Kira, have never left behind even a single scrap of evidence. And now some kid's mistake is carrying that ring away... Like I'll let him.
I'm always thinking this, but damn, Yoshikage Kira, you're one lucky guy... With your friendly demeanor and bold drive, there's no way you won't be happy in life.
My name is Yoshikage Kira. I am 33 years old. I live in northeast Morioh, where there are many villas... I am not married... I'm an office worker for the Kameyu Department Store. Each evening, I return home no later than 8 PM. I don't smoke. I drink, but only occasionally. I go to bed by 11 PM and always get at least 8 hours of sleep... Before I lie down, I drink a cup of warm milk and do 20 minutes of stretching to relax my body... With that routine, I find that I sleep soundly all the way until morning. Like a baby, I awake with no fatigue or stress. And at my last checkup, I was given a clean bill of health... I'm explaining so that you'll understand that I'm a person who wants to live his life feeling at peace. I refuse to create dilemmas—or enemies—that will disturb my thoughts and keep me up at night worrying if I'll win or lose... And by maintaining that approach toward society, I have found that I can attain happiness. Of course, if I were to fight someone, I would never lose.

You ants really think you can find Yoshikage Kira? I'll destroy you. My Stand Killer Queen's Sheer Heart Attack will kill anything it aims for, guaranteed.
For me, it's not really about winning or losing. I just want to survive. I want a peaceful life. It's just that it's in my nature to kill. I will have my happy life!
I really want to show Yoshikage Kira's true nature to the girl on the right... I want to reveal my deep desires to her... I'm dying to touch her thin neck with my hands... and choke her to death.
You want me to leave Morioh!? To live in fear of pursuers, constantly looking over my back without any tranquility or peace?! You should know better than to suggest that to me! I will never leave this town!
Lately, with everything going on, the waves of my life have grown rough and violent...But from now on, I'll be able to live my life with a peaceful mood. I matured last night, all because you cornered me...rather, I felt a truly powerful will radiating from you last night... You even managed to threaten me, Yoshikage Kira. Hahaha oh dear did I let my name slip...?
Even the fact that Rohan Kishibe met you has been erased! That is Killer Queen Bites the Dust! There's nobody you can talk to! Nobody who can investigate you!
For your information... I turned myself into Kosaku Kawajiri not because I was fleeing from you. If I had wanted to get rid of you all, I could have killed you at any time. I didn't simply because I don't have a taste for battle. I dislike combat because it runs counter to the tranquil life that I desire. Winning a single battle is simple, but stress builds up in anticipation for the following battle... It is a foolish act. [...] That was the only reason I didn't get you out of the picture.... Right now you three are the only ones disturbing my tranquility. Those who know my identity are the only ones I have no choice but to fight!
Phewwww~ Back when I was a kid... you know Leonardo da Vinci's Mona Lisa, right? I saw it in an artbook. When I saw Mona Lisa's hands, folded by her knee... How do I say this? It's a bit crude, but... hehe... I got...a BONER. I cut out just the hands... and put them up in my room for a while. I'd like to... cut yours off... too. My name is Yoshikage Kira... I've killed 48 women with pretty hands. You shall be the only one! The only one to know my secret!
What am I supposed to do from here? I don't have the answer for that. But if time continues forever, I may find some sort of happiness by making my 'job' my 'purpose' for living.
I don't carry the tickets with me, but what's important is that I got the seats... And what's most important is to gaze at the brilliant blue sky and enjoy the view. Is there anything more important than that in the world?...
Part 4 didn't start with a clear final boss in mind. Hirohiko Araki envisioned Josuke facing off against various creepy entities in town, and through battles with characters like Angelo and Keicho Nijimura, Yoshikage Kira eventually emerged as a further evolution of those foes. Serial killer stories were popular at the time, such as The Silence of the Lambs film, featuring the sadistic killer Hannibal Lecter, and Encyclopaedia of Murder by Colin Wilson and Patricia Pitman, which documented true murder cases. Kira was inspired by those stories where ordinary-looking unremarkable individuals turn out to be killers.[3]
When creating Kira, Araki didn't just consider how Kira would contrast with Josuke, but also with DIO. Japan's bubble economy had just ended and Araki felt that flashy and larger-than-life characters like DIO who were typical of that era would no longer feel appropriate. Rather than being an ultimate evil charismatic villain, he made Kira a subtle, lurking terror who blends into ordinary life. Araki stated that someone like DIO wouldn't exist in real life, but Kira can, which makes him terrifying.[3]
Araki thought of a backstory for Kira which would portray Kira's abusive relationship with his mother and neglect from his father. Kira's backstory wasn't included in the manga both because it was serialized in a magazine for a younger audience and Araki felt Kira would end up being a very sad villain so readers wouldn't see him as the enemy.[1][25] However, Araki stated that if he were to depict Kira in the modern era, he would likely delve deeper into what made him so evil and gave him a twisted personality, including more of his upbringing and family relationships.[26]
According to an interview with Araki, the idea to have Kira take over Kosaku's life while Hayato suspects his "father" of being replaced was inspired by the Philip K. Dick novel, The Father-thing.[1]
Araki approached David Production during the start of Part 4's anime, suggesting that they should include Kira in several background foreshadowings early on in the part, mainly because he initially didn't know who would end up being the main villain of the story until later on when Kira was introduced.[27]
Trivia
According to a Top 10 List published in JOJO A-GO!GO!, released in 2000, Kira is Araki's favorite antagonist and second favorite character overall.
The character of Yoshikage Kira was the focus of a collaborative photoshoot with the fashion magazine UOMO featuring Japanese model Dean Fujioka, who made an impression of the character.
↑ 1.01.11.21.31.41.5Information from the Character Profile sheets may or may not be considered canon if they didn't appear in the manga. According to Araki in Hirohiko Araki's New Manga Techniques - Chapter 1: What Can Be Changed and What Should Stay Consistent, "the Character Profile is like a sketch—a rough outline of the character. Characters grow and evolve as they live out their lives within the manga. As the story progresses, certain aspects of the profile may no longer align."
Yoshikage Kira (吉良 吉影, Kira Yoshikage) is the main antagonist of Diamond is Unbreakable.
Kira is a paraphilic serial killer who has been lurking unnoticed in Morioh for years. Having lived undisturbed all his life, Kira's routine is shaken when the ghost of his first victim Reimi Sugimoto begs the Joestar Group to look for him and he attracts unwanted attention by murdering Shigekiyo Yangu. Kira is a Stand User and wields Killer Queen to create deadly bombs.
My name is Yoshikage Kira. I'm 3 years old. My house is in the northeast section of Morioh, where all the villas are, and I am not married. I live with mommy and pappy and today I heard them talking about a mistake and something breaking. I am a student for the Kame Yu Preschool for the mentally challenged, and I get home every day by 2 PM at the latest. Today in art class we learned about the Mona Lisa and I got a funny feeling when I looked at it. I don't smoke, but I occasionally drink, milk that is. I'm in bed by 6 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 crying before going to bed, I usually have no problems sleeping until morning. Just like the big boy I am, I wake up without any fatigue or stress in the morning. I was told there were no boo-boos 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, then mommy would give me ouchies. That is how I deal with society, and I know that is what brings me happiness, also car keys. Although, if I were to fight I wouldn't lose to anyone, expect for chad, I don’t like chad.
