Design
Akechi has shaggy, chin-length brown hair with bangs and reddish-brown eyes. He wears a tan peacoat with black buttons, striped black and white tie, black pants and black gloves.

As Crow, Akechi wears a princely pure white royal outfit with red accents and a red, long-nosed mask. The artbook states his mask motif resembles that of a medieval western plague doctor, but in keeping with Akechi being as proud as a tengu, it's also got a long nose. His image is a combination of a noble's attire and a uniform worn by cavalry or guards of honor. As with his Robin Hood Persona, it's meant to give the feeling of putting on the air of a champion of justice, with nothing to do with being a Phantom Thief, robber or burglar of any sort, invoking the image of being at the front of a stage to contrast the protagonist's image of being more of a backstage actor.

Once he reveals his true intentions, Akechi swaps his princely garb for a body-covering, black and purple striped outfit. In this form, he has several black belts strapped around his legs and arms. He also wears a dark enclosed knight helmet, with a deep crimson mask resembling a sharp beak. Much like with Loki's design, it alludes to a lack of agency, is meant to give a chaotic feeling and invoke the question "what's the real you?"

Personality
Akechi is a high school student who conducts a detective business. His abilities as a detective have been widely acclaimed, since he not only has solved numerous cases, but is also able to deal with people from the investigation agency smoothly. His handsome features draw him public attention, and people comment on him as “The Second Advent of the Detective Prince.”

Behind his popularity, however, he is quite lonely and yearns to be loved. He was abandoned by his father, subsequently lost his mother to suicide and never had close friends. He was passed around the foster care system as an orphan and has developed a far more jaded worldview than he initially lets on, even calling himself an unwanted child. He has a desperate desire to be acknowledged, which he is forthright about being the primary drive for his actions as a detective. He also has a narcissistic element to his personality, wishing for others to see him as a hero and those who oppose him as the villains. Akechi claims that he has carefully crafted his public image in the hopes that it would make people accept him. He has the public's support only if he upholds the pretense of being a charismatic idol detective, and his fans are quick to turn on him if he makes mistakes, such as when the Phantom Thieves triumphed over Kaneshiro and Medjed.

In reality, he is actually a subordinate of Masayoshi Shido and his illegitimate son, who carries the killings for him. He also blames his killings on the Phantom Thieves to taint their reputation, and his wish to be acknowledged by Shido pushes him to do both.

Shido both praises and threatens Akechi to manipulate him, and their conversations are always mission-based with no signs of affection. However, despite being a very effective hitman and subordinate for Shido, Akechi secretly resents the corrupt politician for abandoning him and causing his mother to commit suicide. He has sworn revenge on Shido, and his role as Shido's hitman and right-hand man are nothing but a pursuit to fulfill his goal to ruin him when he is at the apex of his power.

After meeting and joining the party, he experiences how it feels to be happy together with friends for the first time in his life, particularly the protagonist. Akechi both admires and envies him, since no matter his social standing and how others see him, the protagonist does not let anything stop him from making his own path. Near the final act of the game, his obsession with getting revenge on his father and desire to be the hero of his own story overshadows his true feelings for the protagonist and the party. In that regard, he has become a traitor for both the Phantom Thieves and Shido.

Before fighting the Phantom Thieves, Akechi reveals his plans for revenge and dismisses the concept of friends and true justice, claiming they are both meaningless and sickening. However, after learning the truth of how Shido sees him from the cognitive version of himself, his goals change to align with the party's, and he sacrifices himself to protect the protagonist.

He usually speaks in a calm and polite, yet unsettling fashion, but when he drops his guise and uses his powers to become berserk as a last ditch attempt to defeat the thieves, his dialogues become wildly aggressive and profane. This is apparent in the Japanese script in that the usual self-referring-pronoun that Akechi often uses is "boku;" when his guise is dropped and he drives himself berserk with his powers, it changes to "ore" instead.

Persona 5 Maniax states that Akechi is endowed with the same wild card power as the protagonist and is the other "chosen one." Despite being overwhelmed with jealousy and contempt for Joker who was surrounded by friends, Akechi says he would have wanted to meet Joker earlier, and doesn't deny what Mona said about him taking a liking to Joker. In the end, he seems to hold complicated feelings toward Joker.

The official Persona 5 Artbook reveals that Akechi lives alone in a city apartment. His main skill is reasoning, and he has a habit of getting lost in thought during conversations. His hobbies include cycling (specifically, with a hybrid bicycle for easy turning in Tokyo), bouldering and playing fashionable games like darts. His guidebook profile also states that Akechi always makes sure to try out the latest popular dishes in order to use food as a conversation piece. Waiting in long lines for this doesn't bother him. He uses his cycling hobby to ride around town, gathering stories to utilize in conversation with adults. Since he spends a lot of time with adults, he has a reputation among Tokyo’s famous hidden stores and high class restaurants, although in truth he has little interest in the food’s flavor.

Persona 5
Akechi is the adopted illegitimate son of Masayoshi Shido, the same man responsible for the protagonist's probation period. His mother, publicly shamed for giving birth out of wedlock, ultimately committed suicide. Akechi grew up resentful of his father and swore revenge, plotting to gain Shido's trust and then publicly disgracing him by revealing their relation to the world. At some point in the past, Akechi acquired the ability to use the Wild Card, manifesting as a Persona and became knowledgeable of the Metaverse. Using his power, Akechi approached his father, posing as an upcoming detective and used his abilities in the Metaverse to be a personal assassin for his father's enemies. Under the belief that his father would soon grow to trust him, Akechi became one of Shido's most powerful allies. In addition, Akechi learned that he could turn Shadows berserk, causing real world incidents which he would turn into cases for him to solve, and soon gained widespread fame with his charismatic personality and good looks, gaining him the title of "The Second Coming of the Detective Prince" and gaining celebrity status as a result.

Prior to meeting the party, Akechi is mentioned by Shadow Madarame as a figure in a black mask, which alarms the Phantom Thieves. He first physically appears in the game watching Madarame's press conference along with Makoto Niijima and is known as "pleasant boy" there, and the reformation of Madarame himself draws the attention of the Phantom Thieves to him. Akechi's first interaction with the group is during a Shujin Academy school trip to a TV station where he was scheduled to appear as a guest. In there, he greets the protagonist when he overhears him talking with Ryuji Sakamoto, Ann Takamaki, and Morgana backstage about pancakes.

Akechi first takes a stance on most public talk shows where he disapproves of the Phantom Thieves actions, but he takes particular interest in the protagonist who defended the Phantom Thieves actions. He approaches the protagonist after the show and expresses that he enjoyed their conversation on the show and hopes to speak again sometime. This causes the Justice Confidant to form between the two. Akechi continues to maintain his stance of his disapproval of the Phantom Thieves, but as the Phantom Thieves continue to change the hearts of corrupted individuals such as Junya Kaneshiro and eventually stop a massive hacking attack by Medjed, the Phantom Thieves popularity explodes while Akechi's popularity takes a sharp dive due to his disapproval.

With the Phantom Thieves popularity at its peak, the Conspiracy uses the opportunity to manipulate their next target by using several accounts to force Kunikazu Okumura to the top of the heist request. The Phantom Thieves accept it due to the inhumane treatment of the Okumura Food's workers and Kunikazu's own daughter, Haru Okumura, wanting to rebel against her political marriage by her father to Sugimura. At the climax of the heist, the Phantom Thieves manage to defeat Kunikazu and force a change of heart. However, as his Palace collapses, Akechi takes the opportunity to assassinate Kunikazu. As a result, during Kunikazu's press conference, he suffers a mental breakdown on camera, leading to many believing that his death was the Phantom Thieves's doing, causing many to throw suspicion on their motives and instantly support Akechi due to his staunch disapproval of their methods.

Sixth Heist: Sae Niijima
Later, Shujin Academy is searching for a guest celebrity to speak at their cultural festival. In a landslide vote by the entire student body, Akechi is unanimously chosen. Makoto invites Akechi to speak at the school and he accepts the invitation. Knowing that she can no longer pull information from her sister, she decides that having Akechi to inquire would be the next best thing. During his speech, he boldly announces that he knows of the Phantom Thieves' identities, but stops before revealing it in order to pull the Phantom Thieves aside to talk. He produces photos taken of the Phantom Thieves escaping Okumura Foods in their Phantom Thief gear and strikes a deal with them. They are to pull off a heist in Sae Niijima's Palace, which Makoto reveals that she is already aware of her sister's palace existence. The Phantom Thieves tell him that they did not murder Kunikazu, which he believes and even states that he had discovered the Metaverse a month prior and had encountered a man in black mask which lead to his awakening. Akechi requests that he accompany them on their heist to catch the real culprit and clear the Phantom Thieves' name while using the photos as blackmail if they refuse. He also requests that they disband after the heist in exchange for destroying the photo evidence.

Left without alternatives, the Thieves agree to Akechi's deal. After everyone leaves the room, Morgana talks to the protagonist asking if he caught on to Akechi, which the protagonist affirms as they first met Akechi on June 10th, more than four months prior and could only have known that the group was talking about pancakes if he could hear Morgana, the only person to mention it. Realizing that Akechi was going to betray them, the Phantom Thieves plan an escape for Akechi's trap.

During the heist, Akechi helped the thieves solve numerous puzzles in the Palace such as providing clues to solving its rigging mechanisms and even gives them permission to attend one of Sae's court cases in order to allow her cognition for them to access the Palace's Member's Floor so they could infiltrate it, as the floor is left for reservation and is inaccessible until Sae's cognition grants them access, even if the party holds the key card to enter it. When Shadow Sae impedes the party's progress by increasing the number of coins required to enter the Manager's Floor of the casino, he secretly used the loan card that Futaba told him to get rid of to loan as many coins from it as possible, allowing the party access to the Treasure.

The heist was successful, with Shadow Sae defeated and the Phantom Thieves convincing her to stop her biased views on the jurisdiction system. However, the victory is cut short when a large police force appears outside of Sae's Palace, having entered the Metaverse. The protagonist decides to act as a decoy so the rest of the Phantom Thieves can escape, Akechi follows the others while the protagonist catches the police's attention and is ultimately caught.

With the protagonist's capture, he is given time to be interrogated with Sae, allowing him to recount the events of the Phantom Thieves' heist and ultimately turns her into an ally. Before she leaves his room, he hands her a cellphone and tells her to show it to Akechi when she sees him. Akechi heads to the protagonist's interrogation room under the pretense of interrogating the protagonist himself. On his way there, he encounters Sae, who had just left the room. She shows him the phone, but Akechi is unaware of its purpose. After Sae leaves, Akechi requests that the guard outside of the interrogation room join him as he interrogates the protagonist, only to immediately take the man's gun and kill him. After shooting the protagonist in the head, Akechi plants the gun into the his hand to give the impression that he committed suicide after killing the guard, and walks away. When he reports to Shido of his success in assassinating the protagonist, Shido considers killing the remaining Phantom Thieves, but Akechi suggests for them to wait to avoid rousing suspicion and assures Shido that they won't seek to avenge their leader as they are nothing without his guidance.

In reality, when Sae showed Akechi the phone, he was transported back into the Metaverse and the security guard and the protagonist he shot were no more than cognitions, so both escaped death. To help Sae believe the Phantom Thieves, Futaba planted a bug onto Akechi's phone to extract a conversation between Akechi and Shido. The protagonist is rescued, but to the rest of the world, the protagonist committed suicide while in custody; the conspiracy was so confident that their plan would succeed that they didn't bother to check for a body afterward, simply releasing a false death certificate.

Alternatively, the protagonist can also reveal the identity of the Phantom Thieves and their accomplices to Sae. If he does and is sure that he has made the right choices, Sae will leave the interrogation room and she runs into Akechi, who she tells him that she got the protagonist to talk about his teammates before leaving, not knowing he came to assassinate the protagonist. Due to Sae not showing him the cellphone, he kills the police guard then kills the protagonist in the real world, and the cops still believe it's a suicide, despite that Akechi didn't leave the gun in the the protagonist's hand in that ending. The protagonist is found to be imprisoned in the Velvet Room, where Igor states that his rehabilitation was not carried through. Caroline angrily calls him an incompetent prisoner due to him being unable to grasp the truth that would prevent him the brink of ruin (In other words, selling out his teammates and Confidants) and Justine laments that the assistance the Velvet Room provided was for naught. Igor then declares the game has ended and ruin is coming to the protagonist's world, and sentences him to spend the rest of his life imprisoned in the Velvet Room. The credits then roll with "Freedom and Security" playing in the background.

Seventh Heist: Masayoshi Shido
Akechi makes a public appearance where he addresses the protagonist's "suicide" at a talk show. The public now gives Akechi their full support for capturing the Phantom Thief, but he states internally that they would not support him if they knew of his origins. He explains that he felt somewhat dizzy, most likely due to his mind being worked up by the task he had undertaken. At that moment, an audience member's phone rings, causing Akechi to recall how Sae showed him the protagonist's phone before he carried out the latter's murder. A while later, Akechi receives sudden orders from Shido to kill the people involved in their schemes earlier than expected, which confuses Akechi who thought everything would settle until after the election. When he expresses some doubt about the matter, Shido immediately threatens him and asks Akechi if he knows what it means to disobey him. At this point, Akechi realizes that there is a high chance the protagonist is still alive and encroaching upon Shido's Palace.

After the Phantom Thieves secure all the necessary letters to enter Shido's Treasure Room, Akechi confronts the Phantom Thieves in the boiler room where he expresses his surprise that the protagonist is alive. He reveals his plan to expose his status as Shido's adopted illegitimate son when Shido wins the election and reveal his crimes, thereby shattering his father's career and credibility. He battles the Phantom Thieves, revealing his ability to make Shadows berserk and that he can use multiple Personas like the protagonist. After his first defeat, he laments that he could not have met the protagonist sooner and prevented the horrible things he has done. While the Phantom Thieves extend their hands to let him back into their groups, he quickly refuses, stating that he hates the protagonist for being everything he could not be and having all the things he doesn't have. He uses his own berserk ability on himself in a last ditch effort to defeat the Phantom Thieves, but ultimately fails. Upon his second and final defeat, the heavily wounded Akechi surrenders and expresses his envy of the protagonist for being surrounded by such loyal friends and that once they expose Shido, they will be hailed as heroes, while all his achievements will be exposed as fraud which will cost him his recognition. Having lost the will to go on, Akechi laments being unable to become someone special; but to his absolute shock, the protagonist and the others point out how he is already special to them and still allow him rejoin them if he desires it, much to his utter disbelief in their sympathy and acceptance.

Before anything else can be said or happen, the attention of everyone present is drawn to the arrival of "Cognitive Akechi," the manifestation of how Shido always viewed him; an obedient puppet. His cognitive self, also having the power to summon and control Shadows, taunts and mocks Akechi's wish for wanting to be accepted, even declaring him the true puppet. The cognition reveals that Shido was planning to kill Akechi all along as soon as the election was over, as well as planning to pin all the murders and incidents on Akechi, and then tells him to take his death as a punishment. Revolted by this revelation and given the choice to either betray the Phantom Thieves once more or die, Akechi chooses to shoot his cognitive self in the stomach before shooting the locking switch on the wall, sealing himself off from the Phantom Thieves. Knowing that they would die if they tried to save him, he puts his trust in the Phantom Thieves to stop Shido for him. As Akechi faces off against his now equally wounded Cognition, the last sound to be heard are two gunshots followed by complete silence. Futaba states that she can no longer sense any presence coming from the other side of the wall, inferring Akechi's death. Later, Sae affirms that Akechi is reported missing.

Shido is very insecure of the exposure of his connection to Akechi as well as the fact that Akechi is his adopted illegitimate son. When the party confronts Shadow Shido after Akechi's apparent death, he says that he would have eliminated Akechi in the end because Akechi knew too much about him, and because Akechi's birth is a taint to his political power (not to mention Akechi reminded him too much of the mother). Shadow Shido gloats about how he used praise to make Akechi dance in the palm of his hand, and says that he was the reason Akechi used his powers in such an effective way, taking the credit for being the one who taught Akechi about mental shutdowns. The party reacts with disgust and condemns Shido for twisting Akechi in such a way and making a teenager commit murders for him.

Failing to complete any of the first six palaces before the deadline causes Akechi to enter the interrogation room after Sae leaves it to give the protagonist time to recuperate. Alone, Akechi shoots the protagonist in the head and leaves. Failure to complete Shido's palace on time leads to Akechi discovering that the protagonist is alive and he appears in the protagonist's room where he arrests him for murdering a guard and deceiving the police, stating that "This game is over." Even if the protagonist fails to complete the heist after Akechi's supposed death, he still appears anyway, however. The hazy filter from the other bad endings is used in this scene as well, leaving whether the scene is truly happening or not ambiguous.

Final Heist: Mementos
It is later revealed that the person who gave Akechi the Wild Card is in fact "Igor," or actually, Yaldabaoth, who pitted him and the protagonist against each other to see if Akechi's desire to destroy and recreate everything is stronger, or the protagonist's desire for rebellion is stronger. He would then remove both sides in an attempt to prove that humanity indeed wants his "salvation," which comes in the form of him controlling the people of Tokyo and stagnating their thoughts. It was also revealed that Akechi is being controlled by Yaldabaoth.

Confidant
Akechi's Confidant is automatically established on June 10th. This Confidant progresses along with the story, and can only progress past Rank 7 if the protagonist answers Sae's questions correctly during the interrogation in November. Because Akechi's stay in the party is only temporary, his battle abilities are all activated when he joins the party. This Confidant will automatically reach Max rank during the main storyline. Maxing this Confidant unlocks the fusion of Metatron. Akechi's Confidant is one of two that does not have a farewell gift to the protagonist, a result of his sacrifice for him.

Persona 5 The Animation The Day Breakers
Akechi makes an appearance on TV, where he is asked his opinion on the Phantom Thieves of Hearts. His response is that whether or not they truly exist, they are criminals who should be brought to justice; he goes on to denounce their actions, and believes that forcing people to change what's in their hearts is wrong.

He is later present at the arrest of Kazuya Makigami and his gang, noticing the protagonist when Kazuya saw him.

Persona 5 The Animation
Akechi's anime counterpart in his Crow appearance, was seen helping Joker escape from the Casino momentarily. Throughout the series, Akechi is seen in interviews on various media devices. Akechi makes his physical appearance during the tenth episode and like before, voices his disapproval of The Phantom Thieves' methods. His dark appearance appears during the battle with Kaneshiro, observing the fight through the security monitors.

Unlike in the game, Ren's interactions with Akechi are shown in detail, such as having him help investigate Futaba's uncle in his blackmail against Sojiro Sakura.

Later on, he fulfills the same role as in the game trying to assassinate Ren during Sae's interrogation during the final episode of the anime. He assassinates Ren after Sae shows him his phone. Judging from the purple flash and the blue butterfly that appears before he enters the interrogation room to assassinate Ren, he had just assassinated Ren's cognitive copy.

In the Dark Sun special, Akechi's role in it is similar to the events of the game, meeting up with Shido and reminiscing on how they met, to him lamenting during the talk show and eventual fight against the Phantom Thieves in the boiler room. Though in this, he is implied to have assassinated the SWAT team responsible for capturing Joker as well, most likely to clean up loose ends.

During the boiler room fight, he fights solo against Joker and is pushed back due to hits from the leader's gunfire. Enraged, he transforms into his true form as the "Black Mask" and summons Loki to attack, a move that leads to Joker's initial persona, Arsene, to clash with his own. He clashes with Ren in a melee battle, being wrathful and baffled as to how despite Ren has what he doesn't: friends.

In the end, Arsene bests Loki and Akechi is defeated. Like in the game, cognitive Akechi appears and summons Shadows to deal with the Phantom Thieves and Akechi himself. However, in the animation's version of events, Akechi is able to kill the cognitive version of himself and returns the black king piece that Joker gave to him before (signifying how Ren finally outplayed Akechi) before closing the boiler's doors. With this version of events, the last we see of Akechi is him staring down a horde of shadows before the point of view switches to the side of the Phantom Thieves. They hear rounds of gunfire go off on the other end, while Futaba confirms that his signal is gone. With the implication of Akechi's fate, the Thieves are saddened by their loss, with Ren, in particular, slamming his fist against the door, but are forced to press on in order to get to change Shido's heart in his stead.

Persona Q2: New Cinema Labyrinth
As the game takes place during the Sixth Heist, Akechi is included as a party member as Crow. He is in the party's default team and is one of the brains of the cast, helping in solving the puzzles and riddles throughout the labyrinths. While he can be seen as distant, he is much easier to interact with by other Persona users in this game and does not display obvious signs of his darker personalities at all, although the Phantom Thieves generally still do not hold him in a high regard.

When meeting P4 cast, he is interested in Naoto Shirogane who is the first Detective Prince before him. Their sharp wit and positions as detectives made Akechi get along fairly well with Naoto. There is a side-quest in which both of them must work together to find the culprit who steals popcorn from the theater (later revealed to be Caroline and Justine disguised as Teddie.)

Akechi also finds his insecurity growing while adventuring the labyrinths from watching the rest of the cast who are able to accept each other for who they truly are. Joker noticed the change in Akechi's behavior, though Akechi denies this. Koromaru, who also sensed this, is being unusually close to Akechi. Ken starts to think that Akechi is different from the rest of Phantom Thieves after seeing Koromaru's behavior towards Akechi, stating that Koromaru only acts that way for people who have deep problems. Akechi once again assures Ken that there's nothing wrong with him, but later quietly reveals his astonishment at Koromaru's sharp instinct.

At the end of the game, he stutters for a bit before returning back to reality alongside the Phantom Thieves, and unlike the other members of the group, he is also non-existent in the post-credits events, indicating that he is still the traitor. However, according to the official artbook, it is actually because that the experience has made him aware of how unfavorable his personality is, and he does not wish to leave as he fears of reverting back to his old self.

Strategy


"I'LL KILL YOU!"

- Akechi to the Phantom Thieves during his boss fight

In the first phase, Akechi is shielded by Guard Dog of Hades and Spear-wielding General. He will cause them to use Desperation which greatly raises their offense at the cost of defense. As these two heavily favor physical attacks, throwing up Physical Ointments or Tetrakarn will speed up this part of the fight.

Once his two minions are down, Akechi enters the fight himself, attacking the protagonist exclusively in this order: Kougaon, Eigaon, Megaton Raid. This makes Akechi easily exploitable by putting up Tetrakarn and Makarakarn on the protagonist in the right order. This pattern will repeat until Akechi's health is halved, in which he will use his next turn to cast Megidolaon. If the battle continues past that turn, Akechi will use his next two turns to Charge then Megaton Raid towards the protagonist.

In the second phase, Akechi focuses on Physical attacks. He will use Tetrakarn to repel Physical attacks and use Brave Blade afterward. Occasionally, he may use Negative Pile which is dangerous if the target is the protagonist and if he is afflicted with Despair. It's best for the protagonist to use a Persona which nullifies the damage of Physical attacks.

After a portion of his HP is down, he'll begin focusing on Magic-based skills. Like the previous phase, he'll use Makarakarn to repel Magic attacks and use a Magic skill. It is recommended not to have Yusuke in the party since Akechi can easily gain One More if Maragion lands on him. The protagonist should be wary of using Personas that are vulnerable to Fire or Curse skills.

When his HP is reduced to at least a third, Akechi will begin to routinely switch patterns, but he doesn't use a Physical skill along with a Magic skill in his turns. Occasionally, and on the first turn of this phase, Akechi will use Laevatein, an powerful Almighty skill, to the protagonist which cannot be deflected. It is wise to have the protagonist guard to reduce the damage, and have his allies recover his HP or also reduce Akechi's offensive damage and increase the protagonist's defense.

Whenever Akechi successfully downs an enemy, he'll use the follow-up to apply Desperation on himself. Otherwise, he'll perform a different action, mainly Dekaja if the protagonist's party has buffs, or Heat Riser to apply buffs to himself, if Desperation is already active.

Persona Q2: New Cinema Labyrinth=

Etymology
"Go" (吾) of Gorō is the archaic form of the first person pronoun "I" in Chinese which carries no meaning in formal Japanese language and is merely borrowed for Chinese translation or naming. Akechi (明智) literally means "wisdom" in Chinese, the same meaning in Japanese would be "kenmei" (賢明).

It could also be a reference to (明智 小五郎), a fictional private detective created by Japanese mystery writer  (a pseudonym for Tarō Hirai) from the story "The Case of the Murder on D. Hill" in January 1925 and continued to appear in stories for a quarter of a century. Edogawa Rampo is considered the father of the Japanese detective story and was a great admirer of Sir. Akechi is the first recurring detective character in Japanese fiction and is clearly inspired by Doyle's. It also makes sense for Akechi to be the rival of the team as in the introduction to the translated version of "The Early Cases of Kogoro Akechi," The Fiend with Twenty Faces (Akechi's main rival) is referred to as "more of an Arsene Lupin than a Moriarty."

It may also be a reference to, a retainer of the notorious daimyo and conqueror Oda Nobunaga who rebelled against him for reasons that are often interpreted as disgust for Nobunaga's flaunting of bushido. This ties to aside of betraying the Phantom Thieves, he is also a traitor to Shido as well, as Shido has ambitions that can be compared to Nobunaga.

Trivia

 * Subsequently, his name could be referencing Detective Kogoro Mori from the Manga Detective Conan written by Gosho Aoyama.
 * Ordinarly, Akechi’s name is written in kanji in the Japanese version. It's used for all of his text boxes, as well as the boss title card for his first fight. However, during the fight against his black masked form, his name is displayed on his boss title card in katakana as "アケチ ゴロウ." This is the only time Akechi’s name is written this way, as the kanji is still used for his dialogue boxes during this same fight.
 * Akechi's outfit when he uses Loki has a pattern blue and black in contrast to his outfit when he uses Robin hood which has a theme of red and white.
 * While Akechi is a Wild Card user just like the protagonist, unlike him, he can only use two Personas. The data mining of the Persona status reveals that his other Persona, Loki, belongs to the Justice Arcana like Robin Hood, Akechi's signature Arcana. That means there is no indication of him being able to possess Personas of other Arcanas, another defining trait of a Wild Card Persona User.
 * In Persona Q2, Caroline and Justine never recognizes Akechi as an "inmate" or "guest," indicating that he does not have access to the Velvet Room in spite of possessing the Wild Card, another trait that most of them have. This further solidifies that he is unable to possess any Personas other than Robin Hood and Loki.
 * As a Wild Card Persona user, Akechi has the ability of being able to change his outfit to better match the Persona he is using. He takes advantage of this to don the regal prince outfit used while he is a party member.
 * Despite being a short term party member, Akechi won first place in Sega Festival 2016 fans polling for favorite party member question.
 * According to an episode of Persona Stalker Club, Akechi's attaché case contains a laptop and documents about cases. The A mark means Akechi and is his own craftsmanship, because he likes to show off. And apparently, the period after the A indicates an abbreviation for "Answer."
 * Within the Metaverse, Akechi's stance mirrors Joker's, but lacks the natural sway that Joker has, instead standing completely still.
 * Many of Akechi's DLC outfits hint at his status as the traitor: he is dressed as a major antagonist for three sets (Boss from Catherine, Ideo Hazama from Shin Megami Tensei: if... and General Munakata from Devil Summoner: Raidou Kuzunoha vs. The Soulless Army) and as a major enemy-turned-ally for the Persona 2 set, as he's the only one wearing the Kasugayama uniform: the same worn by Jun Kurosu and Eikichi Mishina, though the latter being a party member since the start.
 * Just like with Makoto Niijima before, the official twitter account for the Persona series posted a "Happy Birthday" message for Akechi on June 2, 2017 JST.
 * Goro Akechi is left-handed.
 * According to Akechi's Maniax profile, his ideal type of lover is someone who keeps a reasonable amount of distance. Also, if he won 700 million yen, he would travel and see the world after his entrance exams.
 * In Maniax, Akechi's message for someone in the PT reads:  To the leader: "You don’t seem to excel particularly in areas of looks, intelligence, or athletics. Yet I wonder why people tend to gather around you... it makes me very curious."
 * It is impossible to view Akechi's confidant description at rank 9 during the game, as the confidant goes to rank 9 before confronting him and to rank 10 instantly after he is defeated, in which the protagonist is not allowed to act freely during that time.
 * Akechi's confidant was originally planned to be optional. Because he became an enemy later on, it was difficult to incorporate into the plot, so his confidant became automatic.
 * All characters within Joker's party will learn Protect upon reaching Rank 9 Confidant, which has the member sacrifice themselves in order to protect Joker from a fatal attack. Upon reaching Rank 9 for Akechi in the story, Akechi sacrifices himself to protect Joker and his party against Shido's cognitive Akechi and Shadows.
