Yoshikage Kira VS Tohru Adachi (JoJo's VS Persona)

"Some of the biggest serial killers are among the nicest people you will ever meet."
-Steven Magee


Yoshikage Kira, Morioh's Secretly Explosive Serial Killer

Tohru Adachi, Inaba's Secret Serial Killer of the Police Force

Serial killers are some of society's most intimidating people on the planet. And while it may not look it sometimes they even manage to appear mundane. And today I'm putting two of the most notable serial killers up against each other. Will Kira's desire for a quiet life trump Adachi's want for chaos. Or will The Jester's chaos overwhelm the quiet life of the Killer Queen? That's why I'm here to find out who I think would win a DEATH BATTLE!

Before I Start

For Kira, the main focus will be on the JoJo's Bizarre Adventure Manga as well as the anime adaptation. With primary focus on Part 4 but I'll also include other parts for scaling purposes.

For Adachi, I'll be analyzing him from Persona 4/Golden, The Arena Games, as well as the anime and manga adaptations of the games. He'll also be getting scaling from Personas 1 through 4, SMT If..., Devil Summoner and Soul Hackers. But no mainline SMT scaling.

And as usual here are all the sources I used to make this blog:


Background
Kira

In the town of Morioh, nothing is out of the ordinary. That included the childhood of one Yoshikage Kira. In fact Kira would make sure that nothing of his life would ever be out of the ordinary. In school he would only get mediocre grades, and he made sure to never to place higher than third in any competitions. Though as much as he wanted his life to stay mundane and ordinary, his desires were anything but that. When he first gazed upon the Mona Lisa and noticed her soft delicate hands, something within Kira had awoke and he cut off the hands of the picture to admire them in secret from then on. And Kira's fascination with hands would continue to grow stronger and stronger. With this obsession even giving him the desire to kill, with him deciding on the day August 13, 1983 to murder an entire family, simply because he could. And with this decision, Kira's urge to kill grew stronger and stronger throughout the years. On top of all of this, he was even supported during this time by his father who had managed to get his hands on a Stand Arrow. Kira's father then used this Stand Arrow to pierce through his son and grant him his Stand, Killer Queen.

With his new Stand came the perfect power to compliment Kira's murderous nature. The power to completely explode anything without leaving a single trace left. And with this Kira would continue his murder spree for years and years, collecting hands from women until he found a new target. All while working a completely normal job as a salaryman without any hints of suspicion towards him until he turned 33 years old. And on what was supposed to be a normal day for him where he planned out a "date" with his new "girlfriend." With his girlfriend being one of the hands of his most recent victim. But all that happiness for him would start to crumble when he accidentally swapped lunches with the middle schooler Shigekiyo Yangu, who when he tried to return the lunch back to Kira discovered a hand within the packaging. And seeing this Kira had no choice but to silence this child forever and after Shigekiyo tries to find his friend Josuke Higashikata, he sadly loses his life in his struggle with Kira. But Shigekiyo's life wasn't in vain, as he manage to deliver a button from Kira's suit to Josuke and his allies, which turned out to be just the thing they needed. 

With the button, Kira was able to be tracked down to his favorite tailor and was confronted by Josuke's relative, the famous Jotaro Kujo and another one of Josuke's friends and ally Koichi Hirose. After an intense fight with the duo that left him on death's door, Kira fled to find another Stand User that has the power to change the voice and appearance of people. Which Kira used to take the appearance of Kosaku Kawajiri and take over his life. During this brief period of time as another man he would accidentally make his marriage better by being an actually good husband. But Kosaku's son Hayato realized that the man all of a sudden not being abusive wasn't his father. And after discovering this, in a moment of weakness, Kira killed him. And due to his sheer desperation to hide this from his fake wife to not get discovered, the Stand arrow pierced him again which resulting in his stand developing just the ability he needed. 

With Killer Queen: Bites the Dust, anyone who discovers Kira's identity through any means will then explode and die, before resetting time itself by one hour. And the only way to stop him was to get Kira to reveal himself, which Hayato and Josuke managed. And after an extensive battle Josuke and all of his allies corner Kira until fate itself decides to finally punish him. And he dies in one of the most gruesome manners being ran over by an ambulance and even that wasn't enough punishment. As when he went to hell his spirit was completely torn to pieces by all of the spirits of his victims. Putting an end to the monster known as Yoshikage Kira forever.


Adachi

Tohru Adachi desperately wanted some excitement in his life. Growing up he was exceptionally bored throughout most if not all his life. During school he would get the highest grades and score the highest on his exams and even then he'd still be bored. And after graduating he applied to the police force simply so he could legally carry a gun. And while at the police academy he did pretty well. But one day it would come crashing down for him as he made some type of mistake. And due to this mistake, rather than being stationed in a city with any kind of major crime or excitement, he was stationed in the small town of Inaba to be the partner of the detective, Ryutaro Dojima. And Inaba is a town where nothing happens and the most exciting part of the town is it's version of Walmart called Junes. Though due to the fact that practically nothing happens in this town, Dojima and Adachi wouldn't really have many assignments and that resulted in a lack of money and boredom for Adachi. 

But all this would change when a cheating scandal broke out between the idol Misuzu Hiiragi, TV announcer Mayumi Yamano and the politician Taro Namatame, Adachi was assigned to protect Yamano to make sure no harm came to her. But Adachi also discovered the rumor of the Midnight Channel, where allegedly if you looked at the TV at Midnight it would show your soulmate and when Adachi looked at it he saw the silhouette of Mayumi Yamano. So when the two were alone he tried to make advances on her but she rejected him which sent Adachi into a state of rage and he pushed her against the TV in the room and learned that he could enter it, as he pushed Yamuno into the TV. And the next day Mayumi Yamuno was discovered hanging from telephone polls, killed as a result of Adachi's actions. Which finally gave Adachi some much needed excitement. And the very next day a similar thing happened where he saw someone in the midnight channel and attempted to make an davance on her. Only to ultimately be rejected, a good thing since she was a high schooler. But Adachi didn't take being rejected too kindly and this time he deliberately pushed the girl in the TV to kill her. And when she came up dead in Inaba the next day Adachi acted none the wiser. And he would get even more excitement when another person showed up on the Midnight Channel, and he would receive a call from none other than Namatame. And in order to finally spice up the town he convinced him to find the people on the Midnight Channel and throw them into the TV in order to "save" them.

This led to an almost year long cycle of people being thrown into the TV world but being saved by a group of teenagers, led by the nephew of his partner, Yu Narukami. And Adachi loved this game of cat and mouse, to the point where he would "accidentally" leak information about the ongoing investigation to Yu and his allies. But one day Adachi got kinda tired of no one dying. So he sent a letter to the Dojima residence that threatened Yu to stop saving people or else someone he cared about would be killed. Which actually ended up with Yu being brought down to the police station as Dojima saw Yu open this letter and wanted to protect his nephew. Though this surprised Adachi, but his plan ended up working given that Yu's younger cousin Nanako ended up being kidnapped by Namatame and taken into the TV world. And this turn of events even had Namatame become the primary suspect of the serial murders as well as the kidnappings. But when Yu's group thought things through and came to the conclusion that Namatamae couldn't have been the murderer.

And with this, the three brain cells of the group Yu, Yosuke and Naoto came to the conclusion that only Adachi could've been the murderer. Since only Adachi would be able to deliver an unstamped letter directly to the Dojima residence without suspicion. So shortly after the Investigation Team, Adachi accidentally confesses to knowing about the TV world, after which he flees into the TV world to find some solace. But even he couldn't escape the seekers of truth for long and the final confrontation began. With Adachi revealing that he too is a Persona user with his Persona, Magatsu Izanagi. And after a long battle Yu and his crew were able to take down Adachi and even convince him that there's actual meaning to living life. And with this new outlook and being utterly exhausted, he immediately confessed to the murders at the start of the year and willingly went to prison to try and become a better person. 

Skill & Experience

Kira

While Kira has one of the most impressive stands in JoJo's, his skill with using it isn't the greatest. As Kira typically relies on Killer Queen's ability to blow things up instead of trying to master fighting with it. But he isn't completely without skill, he was able to personally kill Shegechi who had previously given both Josuke and Okayusu trouble during their Stand battles. And Kira has plenty of experience with using Killer Queen to murder women for over 15 years. Kira also has great battle IQ with him encountering the Stand Stray Cat which had the power to shoot condensed bubbles, he combined it with Killer Queen's bomb transmutation. Which resulted in Kira being able to shoot long range bombs at his enemies.

Adachi


Adachi surprisingly is one of the most skilled combatants within Persona. Which given that he had only used his Magatsu-Izanagi to fight once during Persona 4. Which was the fight against the Investigation Team, and even with the numbers disadvantage, he was able to put them on the backfoot. His skill gets even crazier as during Persona 4 Arena Ultimax, Adachi could keep pace with the former members of S.E.E.S., now called the Shadow Operatives. The reason this is particularly impressive is that S.E.E.S./ Shadow Operatives have the Persona users Mitsuru Kirijo and Akihiko Sanada. Who have been fighting against shadows dating back to their middle school years. 

Arsenal & Equipment

Kira
Stray Cat

One of the strangest pieces of an arsenal that I've covered. Stray Cat is a plant Stand that has the ability to shoot out condensed air bubbles, and since the bubbles are made of air you obviously can't see them. It can also use this to shield itself from attacks. After befriending the plant cat in his own way Kira stored it within Killer Queen's chest. And with it he combined both it's ability to blow things up with Stray Cats air bubbles in order to make exploding air bubbles.

Adachi

Revolver

Given his status as a police officer, Adachi carries the standard Nambu M60 which is the standard sidearm given to Japanese police officers. It holds 5 bullets in its chamber each being .38 caliber. While most people would choose to shoot their enemies with a gun, Adachi isn't most people and normally uses it as a melee weapon. But should he so choose to he can also just shoot people with it and even use it to summon his Persona for more powerful attacks.


Abilities

Kira
Bomb Transmutation

Killer Queen's main ability is that simply by touching any object, whether they be inanimate or not, they are then turned into a bomb. And Killer Queen's bombs are incredibly deadly being able to completely shred the person affected by them from the inside out. And due to Kira's desires to keep his killing private, Killer Queen developed the ability for its bombs to completely incinerate the body and belongings of his target. Which helped him keep his life as a serial killer secret for almost two decades. Though Kira's bombs can only detonate when either Kira or Killer Queen push their thumb into their index fingers middle phalanx. And if for some reason he or his Stand can't do that then the target won't detonate.

Sheer Heart Attack


Another application of Killer Queen's bomb transmutation ability is that it has more than one bomb. It's secondary bomb, Sheer heart Attack is a long range mini stand that rolls around like an RC car. It can continuously explode itself and is so durable that it can withstand multiple Stand rushes from Jotaro's Star Platinum. It's also heat seeking, constantly moving towards the largest heat signatures before detonating itself. This bomb is tied to Kira's as it's a detachable bomb from Killer Queen's left hand.

Bites The Dust


Killer Queen's third and final bomb as well as being one of the most convoluted things in JoJo (that's not saying much tbh). With Bites the Dust, Kira plants a mini version of Killer Queen on to someone else and that Killer Queen becomes completely autonomous from Kira himself. But it still acts to protect Kira as anyone who discovers Kira's identity as a serial killer is then blown up and killed before time itself is rewound by one hour. And this continues until all of Kira's enemies are destroyed. As each person killed by Bites The Dust during one loop becomes fated to die during the next one. The only way to stop this is for Kira himself to expose his identity or through a direct physical confrontation.

Adachi

Physical Skills

Given that Adachi's a Persona user, his gun isn't his only way to dish out physical damage. With his Persona he even deals out more damage than he would do with his guns and even lessens the risk of he himself taking damage as he can send out his Persona to get in close. Though in order to cast physical skills he has to sacrifice a portion of his HP rather than his SP which is used for magic.

Elec Skills


Adachi has the ability to use his Persona's magic to call down lightning on his enemies. This has a chance to inflict the shock status condition which leaves the person paralyzed and unable to move for a brief period of time. 

Wind Skills


Another element that Adachi can use his Persona to use its magic for. He can summon incredible gales and even miniature hurricanes.

Heat Riser


Adachi has access to the skill Heat Riser which buffs his strength, speed and durability at the same time for a few minutes.

Mudoon


Adachi has the skill Mudoon of the Dark element which has a 60% chance to just straight up instantly kill his enemy.

Status Ailments


Adachi also has the ability to inflict certain status ailments on his enemies. The most common one being Evil Smile which inflicts them with Fear. Which he can then follow up on with the skill Ghastly Wail, which instantly kills anyone with the Fear ailment. He also has the skill Foolish Whisper, which Silences the target, preventing them from summoning their Persona.

Space-Time Manipulation


Within the world of Persona the Shadows have the ability to manipulate the very fabric of time and space. And given that Personas are just Shadows that have been tamed and controlled, Persona users have the same ability. The casts of Persona 3 and 4 even show this further as they were completely unaffected by time itself being reversed.


Guardian Spirits
Kira
Killer Queen

Kira's manifestation of his fighting spirit, that stands by his side is his Stand, Killer Queen. Killer Queen is the source of all Kira's abilities as well as being a pretty damn strong Stand on top of that. It's a short range Stand that has immense speed as well as powerful punches. So it's a pretty good thing for Kira to have and a nightmare for his enemies to face.

Adachi

Magatsu-Izanagi

Adachi's inner manifestation of his heart and soul, is his Persona, Magatsu-Izanagi. Magatsu-Izanagi is the catalyst for most of his skills and abilities. But Adachi can also fight side by side with it to dish out high speed combos, as well as sending it out to fight against other Personas and Shadows without risk to himself for the most part.

Feats

  • Befriended a Stand using plant
  • Was the first known person to get pierced by a Stand arrow twice

Durability

Scaling

Kira
Joestar Family
-Credit to Yuletehdoof of the G1 Team

With Kira's status as the main villain of Diamond is Unbreakable, he was obviously able to face off against it's main protagonist Josuke Higashikata. He's also able to contend with Jotaro's Star Platinum whenever time isn't stopped. And Jotaro's repeatedly stated to have the strongest Stand/ability ever. So Kira should be able to scale to the main family.

Villains

-Credit to Yulethedoof of the G1Team

Kira is the main villain of Part 4 and the strongest one up to that point in the series so he should scale to the previous villains.

Stand Users
-Credit to Yuletehdoof of the G1 Team

Kira's Killer Queen is one of the most impressive Stands in all of JoJo's and constantly threatend the Morioh gang who had some of the strongest Stand Users. So Kira should scale to the random minor threats and allies.

Adachi

The Investigation Team

Adachi has constantly been shown to be on par with the members of The Investigation Team. Especially when it comes to their leader, Yu Narukami. And he even teamed up with Yu to take down a god before. So he should scale to any feats performed by them.

S.E.E.S.


Adachi was able to show relativity to the members of the Shadow Operatives during Persona 4 Arena Ultimax. And given the Shadow Operatives are the former members of S.E.E.S. he should scale to most feats performed by them.

The Phantom Thieves


While it seems odd at first that Adachi could scale to the Phantom Thieves, allow me to explain. Given that he's able to show relativity to the members of both S..E.E.S. and the Investigation Team he can scale to them. But this is further supporting evidence that he should scale to the Thieves too given that during Persona Q2, The Phantom Thieves showed relativity to the prior groups mentioned. And since Adachi scales to them he should scale to the Thieves too.

Weaknesses

Kira

As impressive as he is, Kira does have his faults. He can get incredibly cocky during fights and usually just relies on Killer Queen's ability and never bothered to actually train with his Stand to get better at fighting. Especially since he views his Killer Queen's ability as unbeatable so he even brags during fights. This mindset has even left him getting the piss beat out of him by better Stand users like Jotaro. And on top of all that any damage his Killer Queen sustains, he will also and vice-versa. And this extends to fatal damage as if his Stand dies, he will too.

Adachi


Even with his numerous strengths, Adachi does have his fair share of weaknesses. His sense of pride is incredibly dumb with him intentionally leaking information to the Investigation Team, only to get pissed that people weren't dying anymore. And if his Persona takes enough damage he will undergo a Persona Break and won't be able to summon it for some time.

My Verdict

Stats

When it comes to their stats it's not a contest. Adachi is infinitely stronger and faster than Kira. With the stuff that Kira can do and scale to only maxing out at about city level. With a possible highball of Universal given the nature of Bites The Dust blowing away an hour of time itself. Compared to that of Adachi who himself has a feat of killing a god that was going to destroy the Sea of Souls, an at minimum 7-D plane. If you want an explanation for why it gets that high, here are links to G1's Joker VS Giorno blog, my Joker VS Ben 10 blog and my Joker VS Legionis Blog. Just scroll the cosmology sections. On top of all that the fastest feat Kira can scale to comes out to 1,500 times faster than light. Comparing that with Adachi's best, he can scale to Makoto Yuki who travelled directly from the Physical Reality to the deepest part of the Sea of Souls. And given that he could do that, that's immeasurable. So Adachi takes stats hands down.

Skill & Experience

This is a bit closer but also fairly easy to explain so expect a short summary. Kira has more direct experience as a killer but has also never fought another Stand user prior to part 4. While Adachi lacks the killing experience but has fought a number of different Persona users. So this should result in a tie.

Abilities

Now for the bread and butter of this discussion, how Kira and Adachi's abilities play off each other. To get it out of the way early Adachi wouldn't be affected by either Sheer Heart attack or Killer Queen's main bombs. He's just way too powerful for them to matter. This whole discussion is surrounded on Bites The Dust and if Adachi has a way around it. And I believe he does for two main reasons. The first reason is that simply Adachi would not care to try and find out Kira's identity as a serial killer and would mainly just try and kill him. And the second is that by their nature Persona users are immune to time manipulation and have explicitly showed their immunity to time being reversed which is what Bites The Dust does.

Conclusion

Kira
Advantages:
  • Has more experience as a killer
  • Bites The Dust is tricky to counter...
Disadvantages:
  • Loses the stat trinity by a margin of multiple infinities
  • Less direct fighting experience
  • ...But Adachi's power as a Persona user means it still wouldn't work

Adachi

Advantages:
  • Eclipses Kira in the Stat trinity by a realm of multiple infinities
  • Has more direct fighting experience
  • More than likely resists Bites The Dust
Disadvantages:
  • Less experienced killer

All in all this matchup is pretty clear cut. Adachi just has all he needs to win. With the garguantuan stat gap, more direct fighting experience and a more than likely resistence to Bites The Dust. So with all of that accounted for, the winner is Tohru Adachi.
