Saigiku Jōno/Synopsis

Hunting Dogs Arc
One month ago, Jōno is seen forcing a bank robber criminal into stabbing himself with Jōno's sword, with the condition of them being set free if the sword cuts through them. Out of fear, the criminal picks up the sword but instead tries to attack Jōno but was however counterattacked by Jōno. Jōno is later seen killing the last one of them when an old woman approached him, giving her thanks for saving her from the robbers.

At the present, Jōno appears at the horse race Dazai attends. At first, he calmly asks Dazai which horse is winning, to which Dazai happily answers. Quick to change gears, Jōno handcuffs and arrests him for the former Port Mafia executive's crimes.

After the Decay of the Angel frames the Armed Detective Agency for the political hostage situation and Nikolai Gogol's alleged murder, the Hunting Dogs are summoned by the government to aid in chasing down the runaway Agency members. Upon landing from his capsule, Jōno disrupts a military man's attempt to shoot Fukuchi by catching a bullet without fail. He subtly scolds his commander for raising the troop's heartbeats for no reason, then he threatens to shoot him from behind.

As Tetchō arrives, Jōno takes a harsh approach from the get-go, telling him to leave as soon as he came. He is quick to change gears when the vice-commander lands, worried about her anger extending to all of them. Jōno tries briefing her on the situation, only to be told to shut up, to which Jōno obliges. When Teruko starts acting cheerful around Fukuchi only, Jōno is distraught at how he cannot read her emotions whatsoever.

Elaborating their plan of attack against the Armed Detective Agency, Jōno lists the two possible routes the Agency will take: a southern highway, where the Agency could hijack a getaway car; and a northern train station, where they could blend in among the passengers. Claiming the southern route would be the most logical outcome, he hypothesises that they shall take the northern station to throw them off. Faced with a dilemma of whether to take the northern or the southern paths, the Hunting Dogs split into two teams: Jōno and Tetchō are assigned to the southern road, while Fukuchi and Teruko take the northern station.

Tetchō slashes through the trees along their way and eventually reaches their destination. Jōno voices his dislike for him and humors Tetchō to stop breathing and his heartbeat given Jōno's keen listening senses, compelling Tetchō to hold his breath in. Jōno then detects the Agency near their spot, to which Tetchō prepares for their encounter.

Eventually, Jōno infiltrates their vehicle, pulling out Kenji Miyazawa and Jun'ichirō Tanizaki from inside. Tetchō then prepares his attack on the two detectives, until Doppo Kunikida rams the vehicle into Tetchō to retrieve his comrades. In the Agency's attempt to escape from the Hunting Dogs, Tetchō activates Plum Blossoms in Snow and severs their vehicle into two with his sword.

With the Agency injured, Jōno asks Tetchō to kill Akiko Yosano, whom he calls as the "Angel of Death". Kunikida surrenders, but Jōno is intrigued with his 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. To their shock, Chūya Nakahara arrives and attacks the Hunting Dogs from a chopper with his ability to rescue the Agency, leaving Jōno to wonder how the Agency still has remaining allies.

Despite their high altitude, the Hunting Dogs continue pursuing their targets, with Tetchō using his ability to hang on the chopper. In the end, Kunikida sacrifices himself to let his allies escape by detonating a hand grenade on himself and Tetchō mid-air. After Kunikida is hospitalized and put on watch, Jōno and his fellow Hunting Dogs are requested for dispatch having found the Agency, with Michizō Tachihara rejoining them as the undercover fifth Hunting Dog and cornering Yosano that leads to her arrest.

Sky Casino Arc
As Tachihara returns to the Hunting Dogs' headquarters, Jōno congratulates his successful mafia infiltration and hands him back the task of watching over Tetchō and Teruko. During their meeting, Tachihara reports that the Agency has been last sighted two days ago at the bank, after which eyewitness reports have stopped coming. As Jōno reprimands Tetchō for muscle training during the meeting, Teruko thinks that the criminals are still within the country and may have conveniently found a base and a leader. To investigate, Jōno and Tetchō head to Café Uzumaki.

They bicker with each other over the title of the "strongest Hunting Dog"; Jōno thinks that such title should belong to someone with impressive investigation and capturing skills, unlike Tetchō's physical strength that earned him such feat. Jōno then challenges him that whichever of them can find the Agency first shall grab hold of the title. Jōno begins questioning the café manager about their waitress Lucy, whom the manager dismisses as a negligible employee, possibly quite insignificant to their investigation. Jōno then lauds the manager's coffee and holds him in admiration, though Jōno confesses that he can see through his lie.

As the manager becomes evidently suspicious, Tetchō stabs Jōno's foot for tormenting the manager during interrogation. Tetchō then takes over the questioning, promising him not to charge Lucy with a single crime if he were to confess her location. Aside from her safety, the manager quips that he also wishes the Agency to be saved, so Tetchō vows on his sword that they shall receive a fair trial.

Though Jōno is disappointed that Tetchō resorts to granting the criminals a just treatment with their authority, the manager asks them to save Lucy and tells them that she headed to the Sky Casino. With their acquired intel, Jōno feels that Tetchō might have won their earlier bet.

Later, Jōno visits Kunikida in hospital in the wake of the coin bomb incidents overseas and praises his talent after surviving his own detonation from before. 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.

Before taking his leave, Jōno gives Kunikida time to reconsider his offer and informs him that the Agency doctor shall be executed later that day. He quips how Kunikida's "ideal" of protecting his comrades has now been reduced to nothing, before tossing him his notebook cut in half. He walks outside the hospital, listening to Kunikida's distraught screams.

Vampire Infection Outbreak Arc
Two weeks after Fukuchi's return from Standard Island aboard the Boswellian, Tachihara reports to his fellow Hunting Dogs about the bizarre infection-like incident within the Mafia, specifically with an inhuman Ichiyō Higuchi turning Gin Akutagawa and Ryūrō Hirotsu into her kind, as well as witnessing an undead horde of mafiosi. Though Teruko insults how idiotic he reacted, she believes his story, as it coincides with recent disappearances of various mafiosi. Jōno conjectures it might be terrorism using an ability, which Tetchō thinks is the Agency's next terrorist act. Jōno notices Tetchō's seriousness about the matter, which he jests will earn a mark on his calendar.

Tachihara subtly implies that the Agency cannot possibly be terrorists after recalling how the detectives kept on mentioning being falsely accused numerous times. Hence, he requests them to allow him to reinvestigate the case. Jōno turns to their commander for his approval, though Fukuchi rejects it, claiming that Tachihara's ability is needed in addressing the infection case. Nevertheless, after Tachihara opens his alternative plan using the flash drive he previously broke at the Sky Casino, Fukuchi reluctantly allows him to investigate. Jōno reminds Fukuchi that the flash drive may be another fake planted by the Agency, but Tetchō remarks that Fukuchi nonetheless believes in the possibility that the Agency may not truly be terrorists as he previously said to the UN delegates.

Later at an airport, Jōno bumps into and brushes past Aya Koda to regroup with Teruko and Tetchō. They soon review their operation: One Order shall be brought to the airport, while 18 fake transport operations are to be deployed, with their commander having claimed that Ranpo shall see through the counterfeits and deduce the real weapon. Seeing it as quite bothersome, Jōno recommends taking someone close to the Agency as a hostage to threaten them with, much to the eavesdropping Aya's shock.

Jōno soon detects her heartbeat, thinking how the Agency would come save her no matter what if they use her as bait. As Aya repulses over his thinking, Jōno admits that he merely wishes to hear the voice of the anguished and listen to their destruction regardless whether they are innocent or guilty. He further antagonizes her, until Tetchō stabs Jōno from behind to stop threatening the girl. Jōno annoyingly asks Tetchō not to stab him every single time and challenges him to a swordfight, but Fukuchi arrives and stops them. He issues his final preparation orders to the Hunting Dogs then invites Jōno to come with him.

Along the way, Fukuchi asks Jōno about his thoughts on the Agency's modus operandi, to which Jōno reluctantly answers that the Agency's plot is quite refined whose sadism, he admits, even earns his sympathy, jesting that he does not mind transferring to the terrorists' side in case they lose the battle.

They soon arrive at their destination, where Fukuchi shows Bram Stoker in his coffin to Jōno. Bram reports to Fukuchi that half of the guards have now been turned into vampires, much to Jōno's confusion. Per Tachihara's previous words about how the Agency believes that a mastermind framed them, Fukuchi reveals to Jōno that he is the mastermind. He then invites Jōno to join him in carrying out his plans.

Jōno hears Fukuchi's revelations in inviting him to carry out his plan. Fukuchi then reveals his thoughts about Jōno and his true intention when he recruited Jōno to the Hunting Dogs, in order to ask for his participation in order to obtain his goal. Jōno asks what he needs to do to which Fukuchi reveals his plan to assassinate the Armed Detective Agency and having One Order being a competition among others. He further tells Jōno about the plan the agency may be having - to kill Bram in order to prevent the delivery of One Order. With this in mind, Fukuchi orders Jōno to guard Bram and kill the agency members to which the latter accepts the duty and becoming part of the Decay of the Angel. Fukuchi then leads Jōno to a site where he intended to assault the agency. While walking, Jōno attacks him from behind and slices through his neck much to his surprise.

Fukuchi asks Jōno behind his betrayal, to which the Hunting Dog claims that he prefers the pleasure of helping the people to hearing their despair. With no other choice, Fukuchi summons Shintō Amenogozen and counters Jōno's attack. The latter activates his ability and atomizes himself to escape Fukuchi, planning on exposing him to the Vice Commander and Tetchō. However, Jōno gets trapped and is unable to slip through the door because of the undead Ryunosuke Akutagawa's Spatial Distortion, forcing him to resort passing through the air conditioner.

However, Jōno's particles back at the room are burned by Shintō Amenogozen enflamed with Fukuchi's favorite and the flame enhanced using his ability. Pushed to a disadvantage, Jōno is forced to revert back to his body, during which Fukuchi stabs him multiple times from multiple futures. Akutagawa then bites and infects Jōno, while Fukuchi apologizes having to make Jōno suffer such ordeal. Jōno accepts his possible end, but he quips that the commander's suffering is far from over.

As Akutagawa takes him away, Jōno muses to the time he first suspected Fukuchi: when he previously detected a lie in Tachihara's heartbeat while speaking of the flash drive about the Decay of the Angel. Planning a contingency plan since then despite his partial assurance, he later discreetly handed Aya a memo to come follow him in the airport if she believes the Agency's innocence. This act then implies how he has chosen the individual whom he claims Fukuchi is least wary of, anticipating to hear his commander's distress sooner or later.
