Doppo Kunikida/Synopsis

Azure Apostle Arc
Kunikida was preparing for work, as he arrived a few seconds earlier, he waited before entering, but as he entered Atsushi asked for his help and explained that Dazai had eaten some weird mushrooms. Dazai was acting crazy, but Kunikida decided first to do his paperwork. The moment he was done with it, he knocked Dazai as he was annoying him.

Later they went to check an anonymous tip and first went to the hideout of Rokuzō Taguchi, a hacker informant working for the agency. They work on a serial kidnappings case, and Kunikida enlists Rokuzo's technological skill to find solid leads. Kunikida and Dazai later rescues Nobuko Sasaki from drowning in a tank. Unfortunately, several other kidnapped victims, locked in a gas chamber, perish. Security cameras recording the incident were leaked, an image of Kunikida failing to save the victims published in the newspaper.

On the next day, while Dazai was messing with Kunikida about his ideal woman and having glasses, Kunikida realized something and they called their taxi informant again. In the taxi, Kunikida revealed that the informant was the kidnapper and that he was selling the kidnapped people's organs to the black market. The taxi driver revealed he was being forced into doing this and asked for protection as accidentally he had kidnapped someone from the Port Mafia.

At that moment the Port Mafia started gunning them and Kunikida used his ability to help them get out of the car. Akutagawa then came and started fighting Kunikida, but while fighting police sirens were heard and Akutagawa decided to retreat. Later the taxi driver had given them the place his deals were happening and as they went there, they received a request from their anonymous tipper about a bomb they need to disarm.

At the agency office, the group was discussing the bomb situation and how to deal with it. Ranpo wasn't available at the moment, so they had to start working on solving the situation without him. Kunikida called Rokuzō asking him to try digging up some information on the bomb equipment they found. Later he went into a cafe were Dazai was speaking with Nobuko. As they discussed the bomb, Dazai asked Nobuko about her opinion and she suggested the culprit was related to Azure King. Dazai then tried hooking Kunikida with Nobuko as he was her type and even revealed Kunikida's type to Nobuko, but she thought it was too much.

They received news from Ranpo, as he as done with his case and he told them where the bomb was. Heading towards it, the bomb squad had already found it but weren't able to disarm it. The three of them received calls from Ranpo, Rokuzō and the president. With the new information, they went towards a former defense facility, where they got attacked. Kunikida ended up fighting a man who could put a number on Kunikida and freely control him. As he was no match for him, he saw Dazai struggling with a large man and managed to switch places with him, taking out the man, while Dazai neutralized the other man's ability. Kunikida then recreated the key needed to stop the bomb and they managed to disarm it.

On the next day, Kunikida visited the graveyard, where Nobuko visited him and explained she lied to him, saying that her previous boyfriend had died. As she left, Kunikida was called to the abandoned hospital by Dazai. Unbeknownst to Kunikida, Dazai later has Rokuzo look into Sasaki's claims, leading himself and Kunikida to an abandoned building. When Rokuzo arrives, Kunikida denies the thought of him the Azure Messenger, which Dazai confirms, however, before either he or Rokuzo can clarify the situation, Sasaki appears, shooting and killing the boy.

Sasaki confesses to the kidnappings and murders being her doing. She tells Kunikida she and the Azure King were lovers, and now she takes his place to follow through with his ideals, but with this confrontation, she's tired of killing and living all together, unable to reach those ideals in the first place. Before Kunikida can react, Rokuzo shoots and kills her.

Rokuzo and Sasaki's deaths greatly impacted Kunikida and his view of his ideals. Although he remains true to them, he is constantly haunted by the deaths of those he cannot save, a weight that remains heavy on his shoulders.

Port Mafia Arc
While at a mission, Dazai jumped in the river to commit suicide and then met Atsushi. Kunikida then came yelling at him, but Dazai made him pay for their dinner. While eating, they introduced themselves and Kunikida explained their mission was to capture a man-eating tiger. Upon hearing that Atsushi attempted to run, but Kunikida stopped him. Atsushi explained that the tiger attacked the orphanage he was in and he then got kicked out of it, and now the tiger followed him in the city. Dazai then gave Kunikida a note and went with Atsushi to capture the tiger.

Later that night, Kunikida came to the warehouse where Dazai had mentioned the tiger will appear and had brought some more agency members with him. There Dazai explained the tiger was Atsushi and wanted to welcome him in their organization, which shocked Kunikida as it wasn't Dazai's decision at who joins them.

On the next day, Kunikida found Dazai and Atsushi and again got angry at Dazai. He then explained there was a bomber at their agency office and they all went there. As they were wondering what to do, Kunikida lost to Dazai on rock-paper-scissors and had to confront the bomber, but as the bomber knew who he was, he made Kunikida keep his distance and was careful about his ability. Dazai then made Atsushi face the bomber and act as worthless human and as Atsushi did, Kunikida saw an opening and using his ability took out the bomber detonating device and then knocked the bomber.

Kunikida then got in an argument with Dazai, which gave a chance for the bomber to escape and activate the bomb. As Kunikida was struggling with the bomber, Atsushi decided to sacrifice himself and cover the bomb with his body. But as the bomb didn't explode, it was revealed all to be an act and test for Atsushi, who was then accepted into the agency by Dazai's recommendation.

At a bar, the group was talking and Atsushi ended up guessing each person's previous jobs. He guessed that Kunikida was an office worker and Dazai corrected him being a math teacher. Then they got a call for a client and went back to the office. As Dazai made a move on the client, Kunikida took him in the other room and beat him up. After listening to the client's job, Kunikida gave it to Atsushi and Junichirou and then warned him that if he sees a man named Akutagawa, to run away.

When Atsushi woke up after Akutagawa's attack, Kunikida was next to him reading his notebook. Kunikida explained that Naomi and Junichirou were fine. Kunikida looked calm, but Atsushi noticed his notebook was upside down and as he told him, Kunikida stood up in shock explaining that in the worst-case scenario they get attacked, he will take down the mafia with variety of techniques. Atsushi realized Kunikida was nervous and thought the situation was serious. He decided to leave the agency, so it doesn't get attacked, but the agency still got attacked.

As they were gunned down, Atsushi arrived to see how Kunikida took down the last member of the attackers. The agency had easily dealt with the attack and Kunikida was angry at how much money that will cost them to fix all the damages. Another member reminded him it was his turn to go around with gifts and apologize to their neighbors, which annoyed Kunikida as that was the worst-case scenario he imagined.

While cleaning up their office, Kunikida receives a client request of a murder case, which Ranpo Edogawa accepts. Kunikida and the other Agency members shower him with some praise for his highly dependable deduction skill, upon which Kunikida tasks Atsushi to accompany Ranpo for the case.

The following morning, Atsushi is worried that Dazai has gone missing, but Kunikida, Ranpo, and Kenji Miyazawa all think that he has merely gone off on his usual excursions. Tanizaki, having fully recovered thanks to Akiko Yosano's "treatment", volunteers to help him search for Dazai. Kunikida inquires about his treatment, to which Tanizaki relives the experience in horror. As Ranpo advises Atsushi to have a keen sense for danger, Yosano arrives and spots Atsushi alone in the office, indicating that Kunikida and the others have left the room.

Later, Kunikida reprimands Atsushi for bringing to the Agency Kyōka Izumi, a mafia assassin wanted for 35 murder cases. Atsushi thinks that she is merely being exploited for her ability to commit such atrocities, but Kunikida tells him that abilities do not necessarily bring happiness to their users, much like Atsushi himself. They soon visit Kyōka in her room, and Kunikida immediately interrogates her regarding the mafia. Kyōka tells them that she shall spill information if they treat her to Tachibana Temple for tofu.

Kunikida leaves the expenses to Atsushi, who ends up having his money thinned out due to Kyōka's appetite. She then explains that she was taken in by the mafia after getting orphaned and has since used her ability for assassination missions. Moreover, they find out that the voice giving instructions through her phone is Akutagawa.

Outside, Kunikida asks Atsushi to hand her to the military police despite Atsushi's disapproval, knowing that she shall get capital punishment for killing 35 people. Kunikida advises him not to let someone else beyond saving into his boat lest they drown together, after which he heads back to the Agency to file his report.

While the Agency is busy working with a request from a ministry officer, Tanizaki informs Kunikida that Atsushi has been kidnapped by the mafia. Though Tanizaki suggests they save him, Ranpo reasons out that the Agency is not Atsushi's bodyguards nor did he go to the Agency for protection, logic which Kunikida thinks is right. Tanizaki argues with Kunikida, upon which Naomi Tanizaki brings in Yukichi Fukuzawa himself to make a decision. In the end, the President puts all work on hold and orders the Agency to help bring back Atsushi within three hours.

Eventually, they find a lead on the vehicle that abducted Atsushi, only to learn soon after that the suspects have been killed. Fukuzawa and Kunikida then turn to Ranpo's help; though initially reluctant, the detective deduces that Atsushi has been taken at sea. The President tasks Kunikida to retrieve Atsushi as soon as possible.

Kunikida soon arrives at the sinking cargo ship and demands Atsushi to jump to his boat. However, Atsushi is hesitant to leave Kyōka behind. Noticing this, Kunikida tells Atsushi that failing to save others is a grim reality that they sometimes have to face, admitting himself that he, too, has failed numerous times in his profession. Nonetheless, Atsushi turns back to save Kyōka. Later, after Atsushi defeats Akutagawa, he and Kyōka jump off to the boat, upon which Kunikida commends Atsushi for a job well done.

In the aftermath, Kunikida leaves his fellow members to play with Kyōka at the office, though he has tried to stop them. He soon reports to Fukuzawa about the girl's criminal activities and identity. Kyōka asks Fukuzawa to let her stay in the Agency, but Kunikida tries to reject her request. In the end, the President allows her to stay, much to their surprise.

Minoura and his subordinate later arrive to hand them a request, and he suspiciously notices the girl in kimono. As Atsushi improvises a story about her origins, Fukuzawa tells the officer that Kyōka is his granddaughter, at which Kunikida and the others get dumbfounded. As the police officers leave, Kunikida and Atsushi learn of Kenji's hometown and their rural systems.

As Kunikida skims through the police's request, he tasks Atsushi to give the case a try himself together with another Agency member. Later, he unwittingly learns from Tanizaki that Atsushi went with Kenji and worries that someone simple-minded like Atsushi might not pick up how too peculiar Kenji's methods are. In the end, Kunikida is relieved that Atsushi realizes how Kenji cannot be used as a model to learn from. He then tells Atsushi about Kenji's ability and how it works.

He later expounds to Atsushi that Kenji's ability is akin to untamed nature and that he substitutes this inner fury with hunger, leading to an unspoken rule in Yokohama to never make Kenji angry. Kunikida narrates how Kenji once barehandedly crushed the foot of a mountain to divert a great flood from washing out Kenji's village, leading Atsushi to think what would happen if he were to get enraged. Kunikida merely rhetorically asks if there is anyone in the world who can stop eruptions.

The Guild Arc
Dazai informs his fellow Agency members that the bounty on Atsushi was assigned by the North American gifted organization known as the Guild, which Kunikida perceives to be an urban legend. However, Tanizaki rushes in and tells them that the Guild has arrived at their office. Their leader, Francis Scott Key Fitzgerald, wishes to buy the Agency to acquire their skilled business permit, but Fukuzawa refuses.

The following day, Kunikida and the others learn that the Guild has most likely made their move, including the vanishing of a Port Mafia-affiliated building overnight and the disappearance of Kenji, who saw the visitors out the previous day. Kunikida tasks Tanizaki and Atsushi to locate Kenji, while he and Dazai head out to discuss the issue with the President.

Later, Kyōka is given a mission by the Agency, during which mafia executive Kōyō Ozaki arrives to eliminate Atsushi and retrieve Kyōka. Kunikida and Kenji later arrive to flush out the mafia reinforcements, revealing that they have been notified through Kyōka's phone after it rang. As the Agency gets in a standoff with the mafia, two Guild members arrive along with four more other members. In the end, the Guild members overwhelm all the forces, including Kunikida and his subordinates.

Yosano later treats Kunikida and Atsushi. As Fukuzawa arrives to inquire about their conditions, Kunikida apologizes for failing to prevent the mishap, after which the President heads out. Not long after, Kunikida updates Fukuzawa on the situation, upon which the President has Kunikida relay the message that they are to assemble at the Bankoudou Hall. He soon hears that Fukuzawa may be under attack, and Atsushi, who passes by, suggests they help him at once. To appease his worry, Kunikida demonstrates to Atsushi how he knows the President can easily defeat his attackers.

The Agency convenes at the Bankoudou Hall, where Dazai explains their strategy. To make up for their numbers, they shall split into various teams: one defense team and two offense teams. Kunikida is partnered with Tanizaki as one offense team; Dazai is paired with Atsushi as another offense team; and Fukuzawa, Ranpo, Yosano, and Kenji comprise the defense team. Dazai then finishes with their main objective which is to keep their base hidden as possible, after which Fukuzawa declares that they must survive the three-way ability war.

The mafia eventually comes up with a strategy of using the Agency clerks as bait for the Guild, particularly for Steinbeck and Lovecraft. Upon learning of their tactic from Chūya Nakahara, Fukuzawa tasks Kunikida and Tanizaki to attend to the clerks immediately. Upon the President's advice, Kunikida informs Tanizaki that open conflict with the Guild is imminent, heading out afterwards to save the clerks on time.

As they encounter the two Guild members on the road having trapped the clerks' escape vehicle, Kunikida emerges from Tanizaki's snowfall behind Lovecraft and shoots the two Guild members. As Steinbeck inadvertently loosens his grapevines' grip on the clerks' vehicle, Tanizaki rescues the clerks and directs them to flee to a nearby passenger train. Kunikida holds Steinbeck at gunpoint to stall some time for the clerks to escape. However, Steinbeck anticipates this line of thinking and uses his grapevines to rid him of his pistol. He advises Kunikida on the predictability of oversimplifying situations, which the detective says he shall take note of.

Using the same advice to his advantage, Kunikida pulls out a notebook page from his pocket pre-written with "pistol" and manifests it to shoot at his restraints. He then attacks Steinbeck and hurts his grapevines – which also harms Steinbeck in the process – and quips that oversimplifying situations indeed make one's actions predictable. Kunikida chides the Guild for committing atrocities in foreign countries, though Steinbeck quotes Fitzgerald that such actions simply must be done.

In that moment, Kunikida notices Lovecraft stand up behind him, seemingly unscathed from his earlier gunshots. He asks Tanizaki to activate Light Snow for cover, but Lovecraft's tentacles immediately capture the two detectives. While they are restrained, Steinbeck locates the two clerks through his grapevines, successfully preventing their escape. Kunikida lashes out and questions their means, to which Steinbeck responds how moralists like them would never understand their work.

Provoked with how the Guild puts Naomi in harm's way, Tanizaki uses Light Snow on an oncoming truck driver to have it crash onto Steinbeck and Lovecraft. Upon doing so, Kunikida and Tanizaki are released from their restraints and successfully retreat to the woods.

Later, after Atsushi gets abducted by the Guild, Kunikida approaches Dazai at the Agency balcony and shows a handprint blotch on his neck, asking Dazai what the situation is all about. Soon after, Kunikida is restrained by the Agency members. As he begins to weep bloody tears, Kunikida sees a woman in white kimono and tells Dazai and the others that the curse has begun.

After the incident, Kunikida tries to cheer the unenthusiastic Dazai, wondering why he keeps complaining despite recently saving Yokohama together with Atsushi. Dazai explains how he feels off with the next assignment given to him by the President regarding Atsushi's plan on their next course of action. Fukuzawa enters, and Dazai updates him about the arrangement of the secret meeting with Mori.

As Fukuzawa leaves, Kunikida gets surprised on Dazai's assignment, more so because he is the one planning the meeting. Dazai informs him that he has been tasked with such mission because he is formerly from the mafia, causing Kunikida to collapse out of shock. Later, Kunikida accompanies Fukuzawa to the secret meeting, which ends with the two parties declining to form an alliance.

Later, Kunikida is among the other Agency members who proudly witness Kyōka pass her entrance exam. Eventually, Kunikida and the other Agency members welcome Kyōka as their newest member. He later approaches Atsushi and Kyōka and scoldingly imparts them with various pieces of advice as their superior, especially not to tarnish the Agency's reputation and not to do anything they will regret. Yosano soon grabs and urges him to tell them what he truly wished to say, to which Kunikida complements them for a job well done in saving Yokohama. Yosano then drags him away, asking him to drink with her.

The Guild Aftermath Arc
Following the battle with the Guild, Kunikida fiercely performs his work unlike his drained Agency co-members. The next day, he and the others locate a gang that ransacked Café Uzumaki, in which Kunikida and Atsushi take out the armed guards in their supposedly secure hideout.

Later, Kunikida finishes his day's perfect schedule and sets out to the subway, ignoring everyone else's requests that might deter him from catching his train. Though Dazai is bent on obstructing him, Kunikida chooses to board the train for the sake of work. He spots a man handing a briefcase to a young girl and recalls Tanizaki's earlier report of someone handing a bomb-rigged case to others and detonating it. Kunikida immediately retrieves the briefcase, lets it detonate outside, and contacts the police at once. He assures the girl that help is coming, but she insists that they catch the culprit.

Though initially at odds with each other, they end up going along the tracks, where Kunikida notices bombs along the tracks and recognizes such modus operandi, upon which he soon finds Aya strapped with bombs. From behind, the culprit attacks him, ties him up, and rids him of his notebook, later revealing himself as Shōsaku Katsura, whom Kunikida arrested two years ago. As Katsura spouts his grudge towards him, Kunikida remotely materializes a stun grenade and pins him down.

Kunikida finds out that the signal for disarming the bombs on the tracks sets off the bombs on Aya; in the end, he chooses to disarm the bombs on the train tracks. He embraces Aya as the bombs go off, but Katsura finds them unscathed later on. Knowing that Yosano is at the site at such time, Kunikida reveals detonating the earlier grenade to notify her. As Katsura is arrested, Aya implies that she fancies Kunikida, but, since she does not pass his criteria for a spouse, he rejects her.

Later on, Kunikida and Atsushi visit Katai Tayama to have him look into Moby Dick's control terminal that was previously hacked, but Katai confesses that he is unable to use his ability due to a feeling of unrequited love with a woman he "encountered" recently. Atsushi suggests they find the woman so Katai can confess to her, but Kunikida and Katai are against it; nonetheless, Katai seeks their help into finding the woman. The next day, Kunikida catches Higuchi spying on them amidst the ongoing ceasefire between the Agency and the mafia. To their surprise, Higuchi asks to tell her everything about the woman on the photo they are looking for.

The three search for the woman, and Katai soon catches up to them. They eventually find the woman coming out of a laundromat, after which Katai and Higuchi chase her. In the end, they learn that the woman is Gin, Akutagawa's younger sister. As Katai gets rejected, Kunikida and Atsushi give him some time to recover, as Kunikida knows that he will get back to work after he resolves the turmoil in himself. Kunikida also remarks how beneficial it will be if Katai ever returns to the Agency.

Cannibalism Arc
Kunikida and the rest of the Agency discover that a masked assassin has been recently attacking ability users at night, including Fukuzawa. Later, he and Atsushi search for and find Dazai shot by Fyodor's sniper. With Dazai undergoing medical operation, Kunikida and the others think of their strategy as the mafia arrives at the hospital where the President is taken. Though Tanizaki wishes to kill Mori, the other host of the mutually-destructive virus, Kunikida anxiously ponders on the best possible course of action to avoid an all-out conflict. Ranpo encourages them, especially asking Kunikida as their interim director to issue his comrades with his orders. As such, Kunikida sends out himself and the rest of the Agency to guard Fukuzawa's room.

As they face off with the mafia's main forces led by Chūya, Kunikida and the others begin to dissipate, revealing it as Tanizaki's illusion. In truth, Kenji had blasted through the wall and carried the President out to safety with the others, rethinking their strategy in their escape.

Kunikida and Atsushi search for Alexander Pushkin, the suspected virus ability user, in a criminal den. When they are spotted, they chase the man down an underground tunnel. As they face five armed children, Kunikida subtly subdues them with a tear gas bomb, but he inadvertently grazes a child after aiming to shoot them. Feeling the oddity of the situation, Kunikida and Atsushi soon find a child strapped with grenades. Kunikida asks Atsushi to chase down Pushkin and to leave the child to him instead. Kunikida tries to distract the child and takes out his notebook. However, the child detonates the grenades, leaving Kunikida horrified as he sees the child beneath the rubble afterwards.

While restrained by the Black Lizard, Tanizaki manifests a switchblade through a page from Kunikida's notebook. He and the others soon fetch Kyōka and Tanizaki after escaping from the mafia. Despite their new order from Fukuzawa himself not to fight the mafia, Ranpo persuades them that it is inevitable to fight them after they tried and failed to catch the virus ability user. The Agency members agree to launch a frontal assault at the mafia, except for Kunikida and Atsushi. Ranpo asks Kunikida whether he is willing to bend the rules. Distraught that he let a child die in front of him, thereby refusing to disobey the order to prevent further casualties, Ranpo advises Kunikida that he is the Agency's strongest and noblest, which is the reason why the enemy aimed to break him first.

Kunikida and Atsushi head to Katai's apartment, where they find him missing. Kunikida smashes through the wall and retrieves a hidden camera to watch the footage, which Kunikida claims is Katai's recording in case of emergency. It shows Katai apparently finding the Rats' hideout, only for Fyodor to shoot him from behind. To their surprise, they uncover Katai's bloodied futon beneath them.

Nevertheless, Katai is revealed to have been helped by Sōseki Natsume, who later intercepts Fukuzawa's and Mori's battle and urges the two leaders to flush out their mutual opponent. As a result, Kunikida drives Dazai, Atsushi, and Akutagawa to the Rats' hideout, in which Dazai makes the latter two collaborate in catching the virus ability user. When they soon arrive at the Rats' hideout, Kunikida and Dazai head out for their own mission after Atsushi and Akutagawa enter the hideout covertly.

Eventually, Kunikida, the Agency, and the mafia confront Pushkin altogether at the end of the coal mine, leading the Russian to deactivate the virus. Kunikida is contacted by Atsushi, who tells him that Fyodor is still missing. To Kunikida's confusion, Fyodor is also not found among the ground vehicles exiting the mine, to which they soon find out through Goncharov that Fyodor is not in the hideout in the first place. Nonetheless, Fyodor later gets caught by Dazai in collaboration with Fitzgerald's Eyes of God, leading to the Russian's arrest.

In the anime, Kunikida attends a banquet held by the Agency at a luxury liner given to them by Fitzgerald. He apologizes to Fukuzawa on the Agency's behalf, willing to accept their punishment for disobeying his order not to fight the mafia. Nonetheless, the President smiles at them and is grateful for their efforts.

Perfect Crime Arc
Kunikida gets imprisoned and charged with murder of the child who detonated the grenades at the slums, as the grenades match the models being used by the Agency. Ranpo, helping out a salesman in a shopping district as penalty for disobeying Fukuzawa during the events of Cannibalism, visits him in his cell and promises to break him out of detainment. Kunikida apparently feels helpless, but Ranpo assures him that he will prove his innocence. After all, Ranpo believes that the child would not have died if he read through Fyodor's scheme.

Later on, after Ranpo confronts Mushitaro Oguri – an ability user who colluded with Fyodor during Cannibalism – the latter revokes his evidence-erasing ability, causing various evidence to surface that prove Kunikida's innocence. To note, it is discovered that the grenades used on the child match the Agency's grenades after being stolen during shipping. Thus, Kunikida is released from imprisonment.

Hunting Dogs Arc
One month later, the Agency is awarded by the Ministry of Justice for their contributions in public safety. Kunikida also trains Atsushi in physical combat, in which he urges Atsushi not to let his tiger ability overpower him. He further advises him that the tiger is strong, but he himself is weak. Afterwards, they head back to convene with the others.

Kunikida briefs the Agency on an urgent request by the government about four gruesome murders of government officials, which allude to the five signs that indicate the imminent death of an "angel" in Buddhist scriptures. Fukuzawa orders the Agency to prevent a fifth murder from happening, but Ranpo objects. As he storms out the office, Kunikida tries to stop him, but Fukuzawa lets him be.

Nikolai Gogol contacts the Agency holding government officials hostage. As a test solely for them, he challenges them to save the hostages being tied to chainsaw chairs before they activate within 30 minutes or before any external parties interfere. Kunikida contacts Ranpo, who asks them to be careful of the situation, while he follows down a lead. They head to the hostage site, where Kunikida asks Kenji to stop the incoming military police from interfering their operation.

Outside the hostages' room, Kunikida briefs the others with his plan. In that moment, the hostages scream inside with the chainsaws activating one minute before the supposed time limit. As Kunikida announces that they shall go in, they instantly find themselves clad in the hostage takers' robes having just "removed" their hoods. Amidst their confusion, they find Gogol tied up on a chainsaw chair, who later gets bisected along with the hostages. Justice Vice Minister Tonan, who is contacted by the military police, names the Armed Detective Agency as the Decay of Angels.

A sniper tries to shoot Kunikida, but Yosano quickly saves him. Kunikida immediately asks Tanizaki to use Light Snow to help them escape. They regroup with Kenji and blockade themselves in a room, where they are contacted by Ranpo who warns them about the Book's power spurring the current events. He asks them to avoid capture at all costs despite their innocence, but their conversation is cut short as Ranpo jumps off a building to escape from the police at his end.

The military police fires sleeping gas at them, forcing them to commit suicide as the operatives barge in the room. To their surprise, Yosano resuscitates her four comrades using her ability to take out the police altogether. Kunikida reveals having reproduced a military-encrypted comms device to listen in on the military police. They soon change into the operatives' riot gear and escape from the building.

With enough distance covered from the hostage situation site, Kunikida and the others take a respite in the woods. He tells them that the military police must have dispatched a hunting squad at such time, admitting that the five of them might not be able to do anything against their pursuers. As each of them grasps their situation, Kenji gives them some rice balls and encourages them to push through their crisis and keep living, relating it to a similar experience that occurred in his hometown. Motivated, Kunikida announces that they must first escape in order to rebuild the Agency.

In order to outrun the military's expansion rate, Kunikida lists two options: either they take the northern train or hijack a car down the southern road. After deliberating, Kunikida suggests they go by car, so as not to affect other citizens on the train if the military were to catch up to them. Yosano and the others agree with him and set out southward.

Kunikida soon carjacks a theft-insured vehicle, driving to a secure location where they can hide and gather information. He soon hears three people at the backseat and finds Saigiku Jōno seated between Tanizaki and Kenji. The two try to overwhelm the Hunting Dog, only to get pulled out of the car and left behind. When Tetchō Suehiro prepares to attack them, Kunikida runs him over with the car and retrieves his comrades. They drive away from the Hunting Dogs, but Tetchō easily cleaves their vehicle in half from afar.

As Tetchō prepares to kill Yosano, Kunikida surrenders to the Hunting Dogs. Jōno is intrigued with Kunikida's heartbeat and notes how he feels relief with how his ideals shall run out, further remarking that his lofty ideals are bound to collapse very soon. From a chopper, Chūya arrives and attacks the Hunting Dogs with his ability and rescues the Agency; the payment, however, is to exchange an Agency member to the mafia. As Kunikida ponders that mere ideals shall not help them from that moment on, they find Kenji stabbed with Tetchō's sword, who continues his pursuit. Holding on to his ideals, Kunikida tasks Tanizaki to find the true criminal; he jumps off the chopper to land on Tetchō mid-air and detonates a hand grenade on the two of them.

Kamui Revelation Arc
Upon grabbing Tetchō, Kunikida uses him as a shield to protect him from the grenade's blast, resulting to his hands' amputation. Kunikida is then placed under the Hunting Dogs' custody and brought to a hospital while under surveillance.

Later, Jōno visits him in hospital in the wake of the coin bomb incidents overseas and praises his talent. In exchange for his sole acquittal, Jōno invites Kunikida to join the Hunting Dogs. Despite being told of the perks of working for the government, Kunikida staunchly refuses the offer. Jōno nonetheless expects his answer, though he wonders how Kunikida can now use his ability and write without his hands.

As Jōno leaves to give Kunikida time to reconsider his offer, he informs him that Yosano shall be executed later that day. Jōno quips how his "ideal" of protecting his comrades has now been reduced to nothing, before tossing him his notebook cut in half. Alone in his hospital room, Kunikida screams out of distress and remorse. Kunikida soon senses a sniper aiming at him, after which the shooter destroys his hospital room's lock. A hooded person wearing a gas mask enters his room, proclaims themself as "Kamui", and releases sleeping gas.

In truth, the masked man turns out to be Ranpo, in collaboration with Edgar Allan Poe who sniped down his room's lock, and rescues Kunikida out of the hospital. Kunikida is then sheltered in one of Poe's safe novels together with Yosano and Katai. Afterwards, the four regroup with their allies in Anne's Room.

Upon reuniting, Ranpo tells Kunikida to let Atsushi be, upon which Atsushi embraces Kunikida after knowing he is alive, much to the Kunikida's surprise. Atsushi worries for Kunikida's amputation, but he assures him that Yosano will heal him in no time. With the Agency partially complete, Ranpo instructs Kunikida and the others to search for Kenji and Tanizaki, while he announces that he shall do the "most interesting" task of contacting a certain person.

Vampire Infection Outbreak Arc
Sometime later after Fukuchi's true identity and motive have been revealed, Kunikida convenes with the rest of the rescued Agency members in Poe's novel-recreated Agency office at Ranpo's behest to discuss the erstwhile global conditions caused by the Decay of Angels. When Kyōka soon detects some intruders with them, Demon Snow stabs through the table, under which Tanizaki and Kenji are hiding. Having invited back to rejoin the Agency by Mori himself, they are apparently planning to surprise them, which Kunikida has straightforwardly suggested against.

Fukuzawa soon initiates the meeting, and Ranpo briefs them how 16 armies have fallen due to Bram Stoker's ability, driving the remaining nations to panic and disorder. He informs them that the enemy aims not to ultimately stir the world into chaos but to acquire the mind-controlling ability weapon "One Order". When asked how Fukuchi would possibly use One Order to his advantage, Kunikida realizes in horror who his subordinates would be, to which Ranpo states that he can control the Humankind Army. Ranpo deduces that the Decay aims for world domination, so he prepares the Agency to stop Fukuchi from acquiring One Order within 20 hours and readies to tell his strategy, which is to steal and destroy One Order in a fake passenger plane before it can be given to Fukuchi.

At the airport, Kunikida contacts Ranpo of successfully having bombed the fuel transport vehicle in attempts to obtain One Order. However, the plane carrying One Order starts to swfitly descend. As Kunikida spots it, he then sees Teruko driving a vehicle with Tetchō atop it. Brandishing his blade, Tetchō then activates his ability and tears down the descending plane, then catches One Order's crate for Fukuchi to retrieve. As the two Hunting Dogs regroup with Fukuchi, Kunikida updates Ranpo that the Hunting Dogs have crashed the plane and retrieved One Order, lamenting that they have now lost to their enemy. With Fukuchi successfully obtaining the One Order, Kunikida asks Ranpo what should their next move be.

Kunikida and Tanizaki later pair up in looking for Aya in the airport, holding their own against airport vampires. Kunikida muses why Aya is in the airport in the first place and plans on lecturing her for three hours afterwards, especially for her carrying the source of the vampire outbreak on her back. As he hears a clang behind him, Kunikida soon finds Tanizaki gone, with only one of his sneakers left behind, and calls out to the missing detective. He ultimately gets captured by Fukuchi and, together with Tanizaki, restrained unconsciously on a biochemical device that keeps them alive under its influence.
