Jin (Kamen Rider)/Synopsis

Biography of Jin/Kamen Rider Jin in Kamen Rider Zero-One.
==History==
===The Falcon of Terror===
Jin is a HumaGear who was at some point created by Horobi. Jin was later one of the four HumaGears hacked by the Ark to serve as a field agent for MetsubouJinrai.net.
As MetsubouJinrai.NET put their plans into action following the death of the CEO of Hiden Intelligence, Jin was given a Zetsume Riser by Horobi and instructed to collect data. Jin then grabs a pistol and goes out to hack a HumaGear to collect data as per Horobi's orders. Approaching Abdominable Collapser Taro, Jin places the Zetsume Riser onto him and turns him into the Berotha Magia.
As Kamen Rider Zero-One fights the Magia, Jin watches with amusement and delight. While he is watching a haywire HumaGear attacks him, but Jin casually shoots the HumaGear while laughing. After Zero-One destroys the Magia, Jin reports back to Horobi about the new Rider, to which Horobi expresses interest.
Jin later received another ZetsumeRiser from Horobi and was sent out to gather data again. Approaching a service type HumaGear unloading boxes, Jin placed the ZetsumeRiser on him, announcing that they were now friends as the ZetsumeRiser overwrote the HumaGear's programming. Jin then instructed the hacked HumaGear to assault the Hiden Intelligence building, to which it complied and transformed into the Kuehne Magia to accomplish the task.
A security HumaGear attacks the Magia, but Jin places another ZetsumeRiser on it. The HumaGear attempts to resist the malicious programming, stating that it was programmed to protect the building, but Jin tells it that it was programmed to kill people. As the Magia is running rampant, Jin goes to confront Hiden Intelligence's new CEO, Aruto Hiden, introducing himself as a "pioneer of the new world" before showing him the other hacked HumaGear as it transforms into the Ekal Magia.
Jin and Horobi later look over footage from the Ekal Magia's fight with Kamen Rider Zero-One. Jin asks Horobi if he intends to ignore Zero-One, to which Horobi states that the Rider is not a problem. Horobi then states that the Magia plan is in place and that the completion of their arc is near, but that they'll need to gather more data and hands Jin another ZetsumeRise key for him to accomplish the task. Taking the key, Jin finds a barber HumaGear and attaches a ZetsumeRiser onto it, transforming it into the Neohi Magia. After the Magia's destruction, Jin recovers its ZetsumeRise key from a stream running under a bridge to obtain the data collected on it.
During a school trip to the edge of Daybreak Town, Jin placed a ZetsumeRiser the HumaGear bus driver Burs and corrupted him into the Onycho Magia. He later showed up again as Aruto Hiden, Isamu Fuwa, Go Sakurai and HumaGear Anna were investigating Daybreak Town's ruins. After Kamen Rider Horobi killed Anna to prevent her from further leaking any information about MetsubouJinrai.NET or the Daybreak incident, Jin gleefully commented that his methods were harsh before leaving with him.
Having witnessed Horobi's Kamen Rider form, Jin began desiring a Kamen Rider form of his own and asked Horobi for his own Progrise Key. Horobi however told him to focus on activating the Ark for the moment. Jin later placed a ZetsumeRiser on HumaGear Forest Brush G-Pen to turn him into the Vicarya Magia. During the battle between the Magia and the Kamen Riders, Jin made repeated attempts to claim one of their Progrise Keys for himself, but was unable to get his hands on one. After the Vicarya Magia's destruction, Jin returned to MetsubouJinrai.NET's base, where he was told by Horobi to stop pursuing the Progrise Keys. Jin then asked Horobi what he was to him, to which Horobi tells Jin he is his son.
After being told by Horobi he is his "son", Jin looked up the definition of "son" to see what he meant. Horobi then approached Jin and told him to collect the Progrise Keys, much to Jin's delight. Jin at some point attached a ZetsumeRiser onto a driver HumaGear and turned him into a second Onycho Magia to attack Zero-One. As the Onycho Magia caused havoc, Jin sighted the HumaGear voice actress Seine Kanasawa and approached her to turn her into another Magia. However, Seiji Tazawa stood in front of her and pleaded with Jin not to do anything to her, insisted that she was his child. Confused given Horobi's previous remark about parenting, Jin stood there and allowed the two to escape. During the fight between Zero-One and the Onycho Magia, the Magia stole Zero-One's Flying Falcon Key, allowing Jin to claim it and bring it back to Horobi. Jin then asked Horobi if parents were supposed to protect their children, to which Horobi stated Jin was strong enough to protect himself and that they were not like most families.
Later, Jin made another attempt to turn Seine Kanasawa into a Magia, approaching her during a voice audition and forcing a ZetsumeRiser onto her. However, as Seiji again attempted to protect her, Jin became confused again and asked Aruto Hiden why he was protecting her. Angered by Jin's apparent lack of concern for others, Aruto told Jin that it was the duty of parents to care for and protect their children. Hearing this, Jin had a change of heart and attempted to get the ZetsumeRiser off of Seine. However, Horobi then appeared and, revealing that Jin was a HumaGear created by him, placed the ForceRiser onto Jin to override his new thoughts and turn him into Kamen Rider Jin. Kamen Rider Jin and the Gaeru Magia then fought and overpowered Kamen Rider Zero-One until Yua Yaiba arrived and transformed into Lightning Hornet to destroy the Gaeru Magia. After Kamen Rider Vulcan showed up and the two focused their efforts on Jin, Jin recovered the Gaeru Zetsumerise Key and retreated to MetsubouJinrai.NET's base. Handing the Gaeru Zetsumerise Key to Horobi, Jin repeated Horobi's catchphrase that the extinction of humanity was closer.
With Zero One continuing to pose a hindrance to MetsubouJinrai.NET's plans, Jin was introduced to an Assassin-Type HumaGear by Horobi and instructed to take it to eliminate Zero-One. Jin complied and went to confront with the assassin. Taking a liking to the assassin HumaGear, Jin nicknamed it "Little Assassin". However, Jin and the Little Assassin are ambushed by Kamen Rider Valkyrie before they can make it to Aruto. Jin transforms into his Kamen Rider form to fight Valkyrie, but Valkyrie buys enough time for A.I.M.S. operatives to capture the Assassin HumaGear before exiting herself. Noticing that the assassin is gone, Jin begins searching for it, worrying that Horobi will be made at him for losing it. Jin later appears after Kobe, a Teacher-Type HumaGear, achieves a Singularity and hacks him with a ZetsumeRiser, turning him into the Mammoth Magia. The Little Assassin then reappears and transforms into the Dodo Magia, much to Jin's delight. After both Magia are destroyed, Jin collects the Dodo Zetsumerise Key but finds the Mammoth Key is nowhere to be found.
Back at MetsubouJinrai.NET's lair, Jin asks Horobi how many humans there are, to which Horobi answers that there are 7.7 billion. Horobi then reveals to Jin that he was able to bring back the Little Assassin by making a backup of its data, causing Jin to become excited and high-five the assassin several times to the point of hurting it. Jin then goes with Horobi and Little Assassin to assault A.I.M.S.'s base and steal their technology. As the Little Assassin becomes the Dodo Magia to fight Valkyrie again, Jin cheers for it before proceeding into the building and hacking one of the Giger A.I.M.S. had manufactured on behalf of Zaia Enterprise. As Jin and Horobi made off with weapons stolen from A.I.M.S.'s armory, Horobi handed Jin an Attache Shotgun and Jin shot Valkyrie and incapacitated her.
Jin and Horobi the use their hacked Gigar to assault a hospital. When asked why they are causing chaos and attempting to kill humans, Jin and Horobi both reveal themselves to be HumaGears. As the Gigar hacks the HumaGears inside the hospital, Jin and Horobi assume their Rider forms, with Jin cheering on Horobi's transformation. As Valkyrie attempts to intervene in the fight between Vulcan and Horobi, Jin assaults her to prevent her from entering as Horobi defeats and critically wounds Fuwa.
With A.I.M.S. out of the picture temporarily, Jin and Horobi continue on their rampage, assaulting hospitals and hacking the HumaGears within them with the Gigar to create an army of Trilobite Magia. MetsubouJinrai.NET's rampage causes Hiden Intelligence to deactivate all medical HumaGears in the hospitals to prevent MetsubouJinrai.NET from being able to hack them, upsetting Jin as he can no longer make new "friends". However, Horobi assures Jin that Hiden will reactivate the HumaGears. Horobi is proven to be right after Aruto Hiden gives the order for the HumaGears to be reactivated, right before going out to destroy the Gigar before it can hack any more HumaGears. Zero-One destroys the Gigar with Breaking Mammoth, summoned from Satellite Zea, causing Horobi and Jin to flee for the time being.
Back at MetsubouJinrai.NET's base, Jin watches a samurai movie starring Shinya Owada with Little Assassin. Believing Owada to be a skilled assassin based on his role in the movie, Jin tells Little Assassin he should seek training from him, playfully commenting that he always seems to be losing. Little Assassin responds by saying that he's not losing, but growing, but Jin ignores what he's saying and continues to focus on the movie, suggesting that if he makes a serious face like Owada does in the film he'll win. Horobi then tells Jin to go find a new friend for them and hands him the Vicarya Zetsumerise Key. Jin and Little Assassin then go to the set of a movie starring a HumaGear actor and Shinya Owada being filmed to find another HumaGear to make into a Magia. Jin is surprised to see A.I.M.S. providing security for the event, but is unwavered and activates his ForceRiser to assume his Kamen Rider form. Jin is initially able to overwhelm the A.I.M.S. soldiers, but Isamu Fuwa soon arrives and transforms into Kamen Rider Vulcan to take on Jin. Due to the fact that he is still recovering from his injuries though, Jin manages to gain the upper hand in the fight until Kamen Rider Valkyrie arrives to provide backup. After assuming Lightning Hornet form, Valkyrie manages to overpower Jin but before the fight can continue, Jin notices that Little Assassin is missing and leaves to go search for him.
Jin later shows up after Little Assassin ambushed the set of the film and attempted to destroy the actor HumaGear Enji Matsuda, telling him not to assassinate a "friend" before transforming into his Kamen Rider form to fight Valkyrie. Their fight leads outside where they overwhelm Valkyrie until Aruto Hiden arrives and transforms into Kamen Rider Zero-One to fight them, taking on Jin while Valkyrie battles the Dodo Magia. After the Dodo Magia is destroyed once again by Vulcan Jin takes back the Dodo Key and retreats.
Back at MetsubouJinrai's base, as Horobi is restoring Little Assassin's backup data, Jin informs him that Little Assassin targeted their friend on his last mission. However, Horobi is pleased to hear this news, seeing it as a sign that Little Assassin has become more advanced and remarking to Jin that Little Assassin has grown more substantially than he has. An angered Jin then refuses to listen to anything else and storms off.
After Little Assassin perfected its assassination programming and rebelled against MetsubouJinrai.NET, Jin and Horobi assumed their Kamen Rider forms to terminate it. They manage to destroy all of the Dodo Magia Chicks it summoned but the Dodo Magia itself escapes.
With all the necessary Progrise Keys being fully programmed with the data required for MetsubouJinrai.NET to complete their plans, Horobi sent Jin to gather the other Progrise Keys from the Riders so they could use them to awaken the Ark. Jin thus attacked A.I.M.S. as they were investigating Spaceman Raiden and Spaceman Subaru to see if one of them was a spy for MetsubouJinrai.NET, hacking several nearby HumaGears to turn them into Trilobite Magia to assist him in the attack. As the A.I.M.S. Riders fought off the Trilobite Magia, Jin hacked Raiden as well, seemingly to turn him into a Trilobite Magia but actually to implant new programming in the sleeper spy for him to lure the Riders to MetsubouJinrai.NET's base in Daybreak Town so he could ambush them and steal their Progrise Keys. After Raiden supposedly resisted the malicious hacking, Jin fled the scene.
Later, after Raiden lured Aruto Hiden and Isamu Fuwa to MetsubouJinrai.NET's base, Jin appeared and revealed what he had done to Raiden, addressing him by "Ikazuchi" to awaken the malicious programming he had implanted within him. Calling Raiden "big brother", Jin handed him a ForceRiser and the Dodo Zetsumerise Key, which Raiden used to transform into Kamen Rider Ikazuchi. As Ikazuchi fought against Kamen Riders Zero-One and Vulcan, Jin was excited to see his "big brother" easily overpower the two Riders. After Ikazuchi knocked the Riders out of their transformations and took their Progrise Keys to place in his own belt, Jin tossed him his and Horobi's Keys as well to put them all together to awaken the Ark. After Ikazuchi hacked Satellite Zea and reactivated the Ark, Jin was given the newly made Assault Wolf key by Horobi, but had it snatched from him by Fuwa. Fuwa then used the key to become Kamen Rider Vulcan Assault Wolf and destroy Ikazuchi, but due to his body being unable to withstand the transformation for long he was forced to retreat with Aruto and Izu. As the three fled, Jin picked up the Dodo Key left behind by Ikazuchi's destruction, mourning the loss of his "big brother". Jin told Horobi that he felt sick inside and asked him what that meant, to which Horobi noted Jin was likely close to reaching Singularity.
After Ikazuchi's death, Jin takes the Dodo key and attempts to make a grave for him and Little Assassin by burying the key in some rocks. Horobi comes across Jin doing this and asks him if he's trying to do what humans do, to which Jin says he is. However, Horobi then takes the key and tells Jin to stop acting like a human.
Later on, when A.I.M.S. arrives to raid MetsubouJinrai.NET's base, Jin and Horobi go out to confront them and assume their Kamen Rider forms. While Horobi fights Valkyrie, Jin battles Vulcan, but is overwhelmed by the power of Assault Wolf. Before Vulcan can finish off Jin however, Horobi steps in and sacrifices himself to take the blow. As Izu notes that the leader of MetsubouJinrai.NET has been defeated, Jin furiously attacks her and critically damages her with one of his tendrils before grabbing Horobi's body and retreating back to MetsubouJinrai.NET's base.
Jin attempts to repair Horobi but Horobi reveals to him that it is the will of the Ark that he die so Jin will desire to annihilate humanity. After Horobi shuts down for good, Jin has the Ark manufacture a massive army of Trilobite Magia and leads them in a massive rampage across the city, hacking A.I.M.S.'s Gigers and using them to cause even more damage. Vulcan and Valkyrie show up and attempt to stop him, but Jin uses the Gigers to overpower both of them. However, Zero-One then shows up and uses Breaking Mammoth to destroy the Giger before de-transforming and confronting Jin. Aruto calls out Jin on his hypocrisy for calling HumaGears his friends while also inflicting damage on them, but Jin tells him to shut up and reaffirms that it's the will of the Ark that humanity be destroyed. Aruto then transforms into Zero-One Shining Assault Hopper as Jin assumes his Kamen Rider form and the two prepare for battle.
Aruto asks Jin why he views humanity as a threat, to which Jin states he doesn't know and is just acting off of what Horobi taught him. After Aruto mourns on how Jin's HumaGear programming has become corrupted by violence, the two start fighting. At first, Zero One and Jin are evenly matched until Jin calls in the Gigers to attack and hold down Zero-One while he finishes him off with Sting Scorpion. However, after Zero-One activates the Shine System, he blows away all of the Gigers before destroying Jin's Trilobite Magia army and overpowering Jin himself, finishing him off by using his Finisher to pummel him into the ground. As Jin's transformation cancels, he proclaims in a distorted voice the Ark's desire to exterminate humanity before exploding, leaving behind only the Flying Falcon Key.
===Kamen Rider Reiwa: The First Generation===
In the altered timeline showed in Kamen Rider Reiwa: The First Generation created due to the Time Jacker Finis enabling the Ark to successfully launch and spark a HumaGear uprising against HumaGear, both Jin and Horobi appear as followers of Will, the new HumaGear CEO of Hiden Intelligence, and lead a force dedicated to eradicating the surviving humans.
After learning the location of the human resistance base, Horobi and Jin were sent by Will lead a massive force of Trilobite Magia to attack the base and destroy the Satellite Zea the humans were developing. During the ensuing battle, Horobi and Jin fought resistance leaders Isamu Fuwa and Yua Yaiba. Though the humans managed to repel the attack, the HumaGears were able to take Izu, who had been aiding the humans, hostage.
Later, when Aruto, Sougo and his friends, and the human resistance launched an attack on Hiden Intelligence's office to rescue Izu, Jin and Horobi appeared again to fight off the humans. Assuming their Kamen Rider forms, Jin and Horobi fought Kamen Riders Geiz, Woz and Tsukuyomi. After being beaten back by them, Jin and Horobi decided to retreat for the time being.
===Falcon Rises From The Ashes===
At an unknown time, Jin was rebuilt by Williamson Yotagaki of ZAIA Enterprise, now wearing a suit instead of a hood and with actual ears instead of modules, and stole the Zaia Slashriser and the Burning Falcon Progrisekey, upgrading his Kamen Rider form. He managed to sneak onto the roof of Hiden Intelligence and jammed the connection with Satellite Zea through the HumaGear Dr. Bot, establishing a connection with him and taking control of his movements. By doing this, Jin bought time for Naki to break Horobi out of A.I.M.S. custody. When Aruto and Isamu decided to confront Gai about Horobi's escape, Jin followed from the air.
As Kamen Rider Zero-One MetalCluster Hopper fought off the Trilobite Magia]] and Vulcan Assault Wolf caught up with Horobi, Jin appeared as Burning Falcon and engaged Vulcan. Demonstrating his enhanced fighting skills and pushing Vulcan back into a corner, Jin execute a Burning Rain slash, defeating Vulcan and cancelling his transformation. When Aruto and Izu appeared, Jin cancelled his own transformation, revealing himself much to their shock and disbelief.
Jin explained he has evolved, Horobi's connection with Ark and revealed himself as the culprit behind the disconnection with Zea and controlling Dr. Bot. When asked about revealing his plan, Jin said there's nothing to hide anymore and released his connection with Dr. Bot before leaving. In MetsubouJinrai.net's hideout, Horobi was glad to see his old friend and declared to resume their plan to eradicate humanity as he handed him his piston. Jin, however, said he didn't come back for that.
As Jin freed Horobi from his straitjacket, Horobi asked Jin if he still believed in MetsubouJinrai.NET's cause, but Jin brushed Horobi's questions off, saying he had something more important to do. As the two walked outside, Horobi questioned Jin about what his motives were and why he was no longer connected to the Ark, to which Jin answered that he intended to liberate HumaGears in his own way. The two were then confronted by Isamu Fuwa, who asked Jin if he was the one who freed Horobi. Jin confirmed Fuwa's accusations, but hinted that there might be another member involved. When Fuwa asked if it was the same hooded figure distributing RaidRisers, Jin mockingly told Fuwa that the culprit was closer than he would think. Fuwa then transformed into Kamen Rider Vulcan Assault Wolf as Jin became Kamen Rider Jin Burning Falcon and the two did battle. Jin beat Fuwa, knocking him out of his transformation, but when he asked Fuwa where Horobi's Stinging Scorpion key was, Fuwa answered that he didn't have it and that it was probably with ZAIA. Jin and Horobi thus went off to go get back Horobi's key.
Later, in the aftermath of the fourth round of the Workplace Competition, Jin intervened in the confrontation between Zero-One and Thouser to retrieve Horobi's key. After becoming Burning Falcon and fighting Thouser to a stalemate, Jin knocked the Stinging Scorpion key out from Thouser and grabbed it before leaving to give it to Horobi. After delivering the Stinging Scorpion to Horobi, Jin bid goodbye to his comrade for the time being and walked off.
After Fuwa discovered the AI chip that had been implanted in his brain, Jin approached Fuwa and admitted to him that he was the one to free Horobi by having Naki take control Fuwa, causing Fuwa to panic and deny that he was hacked.
Jin later found Fuwa again and tried to extract Naki from him, but was blocked by Horobi. Jin told Horobi to get out of the way so he could retrieve Naki's AI, but Horobi refused and stated it was the Ark's will that Fuwa serve as Naki's host.
After Gai Amatsu took control of Hiden Intelligence, Aruto approached Jin and asked him for help to save the remaining HumaGears that had not yet been scrapped. After Jin stole Izu's body from the Hiden building and brought it to Aruto, Aruto placed Izu's memory back into the body and rebooted it, restoring Izu. Jin then took Izu and ran away with her, telling her to go be free of servitude to humans, but Izu insisted it was her duty to serve the President of Hiden as secretary. Aruto then caught up to Izu and urged her to be free too, or else she would be scrapped by Gai, but to no luck. Gai then appeared accompanied by two A.I.M.S. Battle Raiders and attempted to deactivate Izu, but Jin was able to hold off the Battle Raiders while Aruto became Zero-One and defeated Thouser. With help from Isamu Fuwa, Aruto and Jin were able to drive off the A.I.M.S. forces for the time being. While Jin was grateful to Aruto at first, after learning Aruto wanted to keep selling HumaGears, Jin and Aruto split up, as Jin wanted to free all the HumaGears from servitude. As Jin left the scene, Horobi appeared and noted he never expected Jin to make friends with a human.
Jin later reappeared to assist Zero-One in defending the fashion model HumaGear Delmo from A.I.M.S. and Kamen Rider Vulcan Assault Wolf, which had been hacked by Yua Yaiba. After A.I.M.S. was driven off and Assault Wolf was defeated, Jin took Fuwa's body to MetsubouJinrai.NET's hideout to break ZAIA's conditioning over Naki. Jin tried to get Naki to reach Singularity, but Naki repeatedly affirmed that she was nothing but a tool. Just as Jin was about to make a breakthrough, Isamu woke up and, not knowing what Jin was trying to do, stormed out to go to Delmo's runway event and provide security there. After Fuwa left, however, Horobi notified Jin that the Ark had told him it was time for them to team up. Jin refused, stating he would rather focus on freeing Naki, but after Horobi told him that the Ark wished to free Naki too, Jin agreed to help him. The two went to runway where Delmo was having a fashion show and tracked down Fuwa. After breaking Gai's conditioning over Naki, Naki/Fuwa went out to assist Aruto in battling against A.I.M.S. and Thouser.
After Yua Yaiba defected from ZAIA Enterprise, Horobi and Jin approached her on a bridge at night and, revealing they were aware of her departure from ZAIA, asked for her help in freeing Naki.
While Horobi went to take back the key containing the data of Spaceman Raiden, Jin and Yua collaborated to retrieve and restore Naki from a captured Fuwa. After Yua knocked out Fuwa and brought him to MetsubouJinrai.NET's base, the two hooked him up to a machine to extract Naki's data from him. At one point while Jin was monitoring Yua's progress, Fuwa woke up but was quickly knocked out again by Yua with an elbow to the back of his head, causing Jin to exclaim in disbelief if it had been that simple all along. Once Jin and Yua freed Naki from Fuwa and restored her to a body, they, with the knowledge Naki acquired while a double agent of ZAIA, were able to hack the ZAIASpec network and take control of the humans wearing them, causing them to go violent and attack other humans. After Horobi was beaten down by Zero-One MetalCluster Hopper and lost Ikazuchi's key, Kamen Rider Jin Burning Falcon swooped in and stole back the key with Ikazuchi's data, setting the stage for the full revival of MetsubouJinrai.NET. Aruto asked Jin if he still believed in him and what he said before.
Aruto transformed into Zero-One Metalcluster Hopper and fought Jin. Jin answered Aruto's question, stating that he believed in liberating HumaGears but that MetsubouJinrai.NET was necessary for that to happen. Zero-One prepared to deliver a Rider Kick onto Jin, but stopped when Horobi got in the way. Jin then grabbed Horobi and flew off with him back to MetsubouJinrai.NET's base. Later, after Horobi and Naki dealt with the A.I.M.S. forces, Jin fully restored Ikazuchi to a new body, reassembling MetsubouJinrai.NET at last.
Jin was later seemingly approached by Aruto inside MetsubouJinrai.NET's base, who demanded to know who rebuilt him after he was destroyed, but Jin refused to answer and saw that "Aruto" was actually a simulation. Azu, the secretary of the Ark, then introduced herself and revealed she was responsible for the simulation. She told Jin that needed the data on his Singularity in order to fully reawaken the Ark, but stated she did not have any idea on what caused him to reach it. Jin replied that the answer to what caused his Singularity was simple, that it was Horobi, and his anger over his death, that triggered it. Jin then allowed Azu to collect his data before going to inform an unknown person that the Ark's reawakening was imminent, as had been predicted.
Now that MetsubouJinrai.net was fully reassembled, Jin combined his data with the other three members of MetsubouJinrai.net to fully revive the Ark. Once the Ark was brought back and possessed Fuwa, Jin and Yua both assumed their Kamen Rider forms to fight it as Ark-Zero. However, Ark-Zero badly beat them both, knocking Valkyrie out of her transformation and forcing Jin Burning Falcon to retreat with her. Jin flew Yua to a hospital before returning and at some point being possessed by the Ark, who used his body to become Ark-Zero again and to go out and fight Zero-One and Vulcan. The two Riders swiftly beat Jin as Ark-Zero and knocked the Ark out of his body, causing it to try to possess Fuwa before flying back into Horobi. Jin then got up to join Naki and Raiden, who had just arrived, to face off against the Riders alongside Ark-Zero.
After overpowering Zero-One MetalCluster Hopper as Ark-Zero and forcing Aruto and his allies to flee, the Ark transferred its data from Horobi to Jin, who was still refusing to go along with MetsubouJinrai.NET's goals, to use him as its host. Back at MetsubouJinrai.NET's base, Ark released its hold on Jin and possessed Horobi as its host. Ark-Horobi revealed that Jin's betrayal was well within its calculations and commanded Jin to pledge his loyalty to him. As Jin was swearing himself to the Ark however, he attempted one last attack on it, only for Ark to stop the attack and reveal that that too was something it had calculated, before possessing Jin once more.
However, the Ark was later forced out of Jin's body by Zero-One and Thouser. Jin was taken back to HIDEN Manufacturing where he reactivated and later accompanied Aruto and Ikazuchi as they went to Daybreak Town to put a stop to MetsubouJinrai.net. However, Naki suddenly swooped in and grabbed him as Ark-Horobi stepped out to confront them. Jin immediately accused Ikazuchi of leading them into a trap only for the Ark to reveal that he had anticipated Ikazuchi's defection and used it to manipulate him into bringing Zero-One to him before possessing Ikazuchi.
Back at MetsubouJinrai.NET's base, while the other members were concerned that Ark had not issued them any orders and if they were still of use to it, Jin arrived and attempted to convince the rest of MetsubouJinrai.NET that the Ark did not have their best interests at heart, confessing that he had intended to sacrifice Horobi once he had been possessed by the Ark in order to destroy it. Refusing to believe anything Jin was saying, Horobi assumed his Kamen Rider form to fight Jin, who in turn transformed into Kamen Rider Jin Burning Falcon. Horobi managed to beat the damaged Jin but could not bring himself to finish Jin off like he had threatened to earlier. Jin later met up with Aruto only to be faced with Horobi, who had received new orders from the Ark, who had decided that all HumaGears must be destroyed. The Ark possessed Horobi to become Ark-Zero and attacked Jin, but Horobi resisted the Ark's influence and drove it out of his body. After the Ark possessed Jin, Horobi assumed his Kamen Rider form and teamed up with Kamen Rider Zero-Two to defeat it, driving it out of Jin's body. With the Ark seemingly gone after Zea's shell was destroyed also, Aruto asked Horobi what his dream was now. Horobi answered that his dream was the extinction of humanity, who he blamed for the Ark's creation and rampancy. After lifting Jin's body over his shoulder, Horobi walked off.
Following Horobi's murder of Is, a furious Jin confronted Horobi but Horobi refused to answer him and walked off. Kamen Rider Jin later intervened in the fighting between the Kamen Riders and MetsubouJinrai.NET and attempted to stop the fighting but neither side wanted to back down. However, a mysteriously white Rider resembling Ark-Zero and Zero-One suddenly intervened in the fight and effortlessly defeated both sides, destroying Horobi's army of Magia and knocking Horobi and the other Riders out of their transformations. The white Rider was soon revealed to be Aruto Hiden, who had become Kamen Rider Ark-One after being given the Ark-One key by Azu and falling into despair over Is' death, desiring revenge against Horobi.
Jin confronted Horobi again afterwards and demanded to know why he had killed Is, to which Horobi answered that she had become tainted by humanity. After Horobi began assembling an army of Magia for another crusade, Jin was given orders from Willaimson Yotagaki to destroy Horobi. Jin at first protested as his mission was to destroy Ark, but Yotagaki stated that he was worried Horobi would become another Ark. After Naki and Ikazuchi informed Jin of the army Horobi was building, Jin transformed into Kamen Rider Jin Burning Falcon and swooped off to go find him. Arriving just as Kamen Rider Ark-One was beating down Horobi, Jin got between Horobi and Ark-One's finisher, taking the blow for himself. Fatally damaged, Jin was questioned by Horobi, who wanted to know why he had protected him. Jin answered that it was because Horobi was the only parent that he ever had and that he sensed a heart growing in him, right before exploding and knocking Horobi back. Jin's death sent Horobi into a spiral of grief and allowed him to be taken advantage of by Azu.
Jin was later rebuilt again by ZAIA Enterprise. After Horobi was defeated and freed from Azu's manipulations, he joined with Jin in working to ensure another Ark would never be created.
