- "(Fangire!) Please return that life to God!"
- ―Ixa's pre-battle catchphrase[src]
Keisuke Nago (名護 啓介 Nago Keisuke) is a 22-year-old elite member of the Wonderful Blue Sky Organization and the main user of Kamen Rider Ixa (仮面ライダーイクサ Kamen Raidā Ikusa), the secondary rider of Kamen Rider Kiva.
Kamen Rider Kiva
Keisuke encounters Wataru when he is after a German fugitive, gaining the young man's praise for his confident exterior. When he learns Kiva has returned and that Shima had known all along, he demands permission to take Kiva out with the Ixa System. However, Shima assigns him the task of keeping Megumi safe, deciding to use that to have Kiva come to him and kill him. However, when Megumi threatens to file a restraining order, Keisuke uses Wataru to do the job for him instead. When he finally faces Kiva, Keisuke is about to become Ixa without permission until the Sheep Fangire kidnaps Megumi in the confusion. He is currently unaware that the person he is mentoring, Wataru, is the individual he is trying to kill. When encountering Kiva, Wataru manages to evade him, not engaging in any form of combat against the person he looks up to. However, when he was ultimately left with no choice, Wataru reluctantly transforms into Kiva and soundly defeats Ixa. Since then, Keisuke becomes mentally unstable to the point of attacking criminals without mercy while proclaiming that the Ixa System lost, not himself. Attempting to snap Keisuke back to his usual self, Shima presents him the Powerd Ixer, which is completed by the time the Rook fully reawakens. Unfortunately, Keisuke's encounter with the Seastar Fangire only drove Keisuke even more insane as he became obsessed with obtaining one of the Fangire's buttons as a memento of defeating him. Keisuke eventually got the button and added it to his collection, seemingly snapping back to reality.
After unsuccessfully trying to find out who Kiva really is by way of a fortune teller Kengo Eritate knew, Keisuke scolds Kengo for calling him 'old man' repeatedly (even though there is only a year's difference between them in age) and fights with Megumi against the Ladybug Fangire, with him and Kengo being kidnapped in the process before he shatters the Ladybug Fangire, forced to work with Kiva to destroy the Six Pillars Sabbath born from the remains. Since the Ladybug Fangire incident, Keisuke gains the admiration of Kengo who desires to be his apprentice to perfect his musical skills. While eavesdropping on a conversation between Megumi and Shima regarding his erratic behavior, Keisuke finds out that a new upgrade being developed for the Ixa System, and is even more pleased that he will retain the Ixa System even after losing it briefly to Ryo Itoya, the Spider Fangire. Though he came close to being removed as Ixa's user, Keisuke succeeds in fooling Shima to let him stay as the user by pretending to admit he was flawed, becoming the first to use the upgraded Ixa System and its stronger form, Rising Ixa.
However, a man named Tanahashi uses his connections with the police to arrest all Wonderful Blue Sky organization members for the previous Ixa disregarding him in a Fangire attack and put him in the hospital, leaving him in a coma and unable to finish a painting of Maya he was working on. With Keisuke forced to run on the lamb, he encounters Jiro who him shows to Castle Doran's Time Door to give him the means to travel back in time. In 1986, he encounters Otoya and Yuri, learning that Otoya is the previous user of the Ixa System and tries to get the Ixa Knuckle from him. Keisuke then encounters Maya and quickly falls in love with her, though denies it, though he failed to her question about human love and gives her his good luck charm, his very first button as a bounty hunter, with a diamond-encrusted crown on one side. After learning that she was actually a Fangire, Keisuke manages to steal the Ixa Knuckle from Otoya and alter time by allowing Tanahashi to get away from the Cicada Fangire without injury. Once back in his time, after aiding Kiva in his fight against the Crab and Cicaida Fangires, Keisuke learns that the button he handed to Maya in the past now belongs to Wataru, who informs him that his mother gave it to him as a child. The revelation ultimately led Keisuke to learn that Wataru and Kiva are one and the same, seeing Kiva is not as much of a threat as he was told and deciding to take Wataru as an apprentice to ensure that while not caring about Kengo's feelings. Since then, Keisuke has been making regular visits to Wataru's house and joining him in his baths to advise the "right course" to take. However, Keisuke soon sees the consequences of his past actions when Kengo returns, trained by Shima to be a more suited user of the Ixa System when Keisuke gets injured in his fight against the Horsefly Fangire. Since losing the Ixa System, Keisuke made various attempts to either spite Kengo for taking over as Ixa or to help him, with Kengo thwarting each attempt at every turn.
Keisuke helps Wataru formally reveal his identity as Kiva to the rest of the organization, but also informs them that he is not a threat. However, he becomes stunned when Wataru reveals that he is half-Fangire. When Shima orders the members to eliminate Kiva, Keisuke pretends to follow orders and shoots near Kengo's (as Ixa) feet instead to delay his battle with Kiva. However, the battle becomes more intense when Taiga has Bishop awaken Wataru's Fangire nature until Keisuke calms him down. Although he was attacked by Kiva, he still trusts him, especially when he defends Kiva in front of Shima. After hearing that Wataru has become a recluse again, Keisuke desperately tries to get Wataru out, from coaxing him at the gate to even breaking into his house. However, when he calls Wataru to help Kengo, who is fighting the Seamoon Fangire and losing when Bishop arrives, Wataru informs him that this is his last battle. Realizing that Wataru is serious, Keisuke takes the Ixa Knuckle to decides to fight the Seamoon Fangire in Wataru's place until he is simultaneously attacked by both the Swallowtail Fangire and Saga. After being saved by Kengo, Keisuke manages to defeat the Swallowtail Fangire before Wataru returned as Kiva.
After Shima's death, Keisuke attempts to succeed his leader as the president of the Wonderful Blue Sky Organization, wishing to become stronger as a manifestation of Shima's will. He manages to defeat the Swallowtail Fangire again as a display of his newfound strength. However, while trying to protect Megumi from the revived Fangire, Bishop manages to seriously injure him. The blow was severe enough to cause Keisuke to gradually lose his eyesight. Due to this handicap, Keisuke considered quitting the Blue Sky Organization if not for Megumi intervening and encouraging him to continue as Ixa. He realizes his true feelings for Megumi as he finally defeats the Swallowtail Fangire for good and regains his eyesight. Days after the final battle, Keisuke marries Megumi prior to joining Wataru in a battle against a mysterious evil from the future.

Ixa's primary gimmick is a "heat gauge" that builds up as long as Burst Mode is active; he can still transform from Save Mode to Burst Mode when the "heat gauge" was still decreasing; if it fills up completely, the suit overheats, leaving Ixa immobilized and vulnerable temporarily and can't transform back to Burst Mode until the heat gauge finally reaches 0 for Ixa to transform back to Burst Mode. To prevent this, the player must periodically change to Save Mode, which has lower stats but gradually vents the built-up heat. Ixa's final form is Rising Ixa, and his Super Move is the Final Rising Blast.

Keisuke is known to be an elite member of the Wonderful Blue Sky Organization and the current user of the Ixa System, working as a bounty hunter by capturing criminals and taking a button from them as a memento. He originally had an intense hatred towards Kiva due to what he heard of the previous one, intending to kill him until he learns of Kiva's true identity and sees him as an ally to mankind.
He also has a belief in "humanity's full potential", which gives him the impression of a superiority complex to some people with the ideal that he's always right. He has a prejudice for certain people like Wataru, as he believes they are everything his ideology of "humanity's full potential" is against. Because of this ideology, he has a distaste for music, as he feels it is a waste of that potential. It was due to his intolerance for sinners that Keisuke played a part in the suicide of his father years ago, exposing him to the media for taking a bribe. However, though he has a sense of righteousness, Keisuke's perspective on it is warped in his desire to purge the world of evil, refusing to accept the world in grey and going berserk whenever he loses a fight or is denied his quarry.
Over time, most of these personality traits would eventually wane, although his sense of justice has not changed. When Keisuke transforms to Ixa, he usually says, "Fangire… Please, return that life to God!" (ファンガイア…その命、神に返しなさい Fangaia… Sono inochi, Kami ni kaeshinasai!).
Kamen Rider Ixa
The IXA system, an acronym for Intercept X Attacker, is a Rider System developed for fighting Fangire. It has been continuously updated since 1986, with Keisuke using Version X for the majority of the series until it is upgraded to Version XI, allowing access to Rising Mode.
Both Ver.X and Ver.XI have a golden projection of the Ixa System instead of the original's bronze color. A total of six Fuestles are available to the user as well as a new weapon: Ixa Calibur. It does not exhaust the user's body like the prototype, though any other side effects are still unknown.

- Ability Parameters:
Burst Mode (バーストモード Bāsuto Mōdo) is Ixa's attack mode, where Save Mode's visor opens up to reveal Ixa's eyes. A wave of intense heat is produced when Ixa transforms into Burst Mode from Save Mode. Ixa can use Fake Fuestles to gain access to Kiva's Arms Monsters, although unlike Kiva, they do not grant him a new form.
Kamen Rider Ixa is composed of the following parts:
- Ixa Met (イクサメット Ikusa Metto) - The helmet. It is composed of Ixa Platinum (イクサプラチナ Ikusa Purachina), a diamond-hard material made exclusively for Kamen Rider Ixa. Ixa Platinum was developed from 8AL-7V Titanium (8AL‐7Vチタニウム 8AL‐7V Chitaniumu), one of the strongest current alloys on Earth, and is considered as the material that next-generation weapons and armor would be made out of. The metal was obtained via special routes. All information is transferred to the user within via internal pads that mount through electrical contact.
- Hunting Glass (ハンティング・グラス Hantingu Gurasu) - The eyes. They are ultra-wide lens that possess a 180° field of view in front, and video information captured is transmitted to the wearer inside via an in-helmet terminal. It also contains a type of night vision scope function that can even see in darkness with zero visibility, and a Super X-Ray (スーパーXレイ Sūpā X Rei) function that allows Ixa to see through a 5 meter thick iron plate. The Hunting Glass can record images via a digital camera lens and save it onto a built-in disk.
- Access Signal (アクセスシグナル Akusesu Shigunaru) - A blue light on the forehead. It blinks when a computer within the Ixa System accesses internal disks.
- Cross Shield (クロスシールド Kurosu Shīrudo) - The golden cross-like visor. In Save Mode, it closes down to cover the Hunting Glass. Immediately after transformation, the Cross Shield closes to prevent the suit from self-destructing and to protect the face where high precision instruments are located. In Burst Mode, all energy is concentrated in one point (the weapons) to enable devastating special moves. Since Burst Mode not only consumes considerable energy but also puts a high load on the suit and the built-in computer, continuous operation in Burst Mode for more than 30 minutes is highly dangerous.
- GPS Bit (GPSビット GPS Bitto) - The blue tips on top of the Cross Shield. They are antennae that lets Ixa know the location of an optical beacon as if they were using a satellite.
- Poisona Filter (ポワゾナフィルター Powazona Firutā) - The white section between the eyes. It is a device that decomposes and purifies all toxins to supply safe air to the wearer.
- Masker Regulator (マスカーレギュレーター Masukā Regyurētā) - The mouthplate. An ultra-small oxygen cylinder in installed, enabling approximately 360 minutes (6 hours) of underwater activity and in low oxygen conditions.
- Sol Mirror (ソルミラー Soru Mirā) - Chest-mounted power unit. It is a next-generation power engine that increases stored power by hundreds of times. This energy converted by the Ixa Engine (イクサエンジン Ikusa Enjin), a black boxed device, transcends human intelligence. In order to efficiently cool down the heat, which is produced as a by-product of the tremendous energy, an opening around the central mirror is used as a heat dissipation block. Small indicator lights arranged around the centre in a cross-like pattern indicate the flow of energy. The indicator placed in the middle top is red, and the indicators to the left and right are green, and are said to be the ideal indicators of energy.
- Delta Earth (デルタアース Deruta Āsu) - Aerial discharge-type grounding systems provided on the shoulders, hips and back. Discharges high voltage that flows excessively through the suit into the air, reducing the burden on the body.
- Sol Flasher (ソルフラッシャー Soru Furasshā) - The light bars on the shoulders. Energy can be concentrated here to be used as a flash grenade. The amount of light is 3 million candela. The intensity of the flash can lead to blindness in ordinary people with a single shot, making it even more effective against Fangires, who dislike light. Therefore, it can be said that this is specifically anti-Fangire equipment. Additionally, during normal operation, it plays the role of a condition signal that flashes red when a yelow light pops up, a malfunction occurs, or when battery level is significantly reduced.
- Black Armor Suit (ブラックアーマースーツ Burakku Āmā Sūtsu) - The bodysuit. It is an inner suit that wraps around the wearer and protcts them from external impact. It is made from Carbotech Linen (カーボテックリネン Kābotekku Rinen), one of the strongest synthetic fibres ever made. Theoretically, it can withstand temperatures of 2000°C, and boasts an intense tear strength of 200t.
- USM (Ultimate Servo Motor System) (USM（ウルティメットサーボモーターシステム） USM (Urutimetto Sābo Mōtā Shisutemu)) - The servomechanisms. It is an ultra-compact high-power motor that produces power equivalent to a 5000cc-class industrial combustion engine. By connecting both upper and lower arms with a strong ultra-thin inner frame, and assisting the arm with artificial muscle fibre (マッスルファイバー massuru faibā) which operates via electrical signals, the user is given tremendous extraordinary strength. A similar system is installed within the legs.
- Ixa Armor (イクサアーマー Ikusa Āmā) - The arm armor. Has a hardness of 8.522. It is made of Ixa Platinum. It also contains sterling silver (スターリングシルバー sutāringu shirubā), a material that dislikes Fangires, and 87 Titanium (87チタン 87 chitan).
- Hunting Grabs (ハンティング・グラブ Hantingu Gurabu) - The hands. An ultra-thin inner frame is built into the USMand the fingertips, providing 20 times the grip strength of ordinary people. Electrical contacts are built into the palm to connect to the Ixa Knuckle.
- Emergency Battery (エマージェンシーバッテリー Emājenshī Batterī) - Spare power packs contained in the legs for when Ixa runs out of power. The power transition is automatic and can always be carried as a backup power source. The main power unit can operate up to 12 hours while an Emergency Battery can operate up to 6 hours.
- Power Knee Unit (パワーニーユニット Pawā Nī Yunitto) - The knees. It incorporates an assisted artificial knee joint with USM, creating superhuman leg strength. Since a large amount of electricity flows through it, a bunch of Delta Earths are provided to efficiently discharge excess voltage to reduce burden.
- Super Absorber (スーパーアブソーバ Sūpā Abusōba) - The ankles. The ankles are wrapped in multiple layers of muscle fibre, providing tremendous leg strength. In order to reduce burden to the legs, air shock absorbers (エアショックアブソーバ ea shokku abusōba) are incorporated on both sides of the ankles and on the soles of the feet.
Kamen Rider Ixa has the following finishers:
- Broken Fang (ブロウクン・ファング Burōkun Fangu) - By inserting the Knuckle Fuestle into the Ixa Belt and pressing the Ixa Knuckle, Ixa can execute a devastating punch with the Ixa Knuckle.
- Ixa Judgement (イクサ・ジャッジメント Ikusa Jajjimento) - By inserting the Calibur Fuestle into the Ixa Belt and pressing the Ixa Knuckle, Ixa can use the Ixa Calibur to perform a powerful slash. When performing the Ixa Judgement, a vision of the sun appears behind Ixa.

Ixa Ridewatch (イクサライドウォッチ Ikusa Raidowotchi): Based on Kamen Rider Ixa Burst Mode, this Ridewatch would provide access to the IxaArmor. It is dated 2008.
- Wataru Kurenai: Keisuke initially took Wataru as his pupil blindly because Wataru admired him. Before he knew Wataru is Kiva, he viewed Wataru as Kiva an enemy. He even went far saying to Wataru that he always right and didn't believe that Wataru is Kiva. However, after learning that Wataru is indeed Kiva, he devoted himself to the fullest on aiding Wataru, even goes far on teaching him to be a strong bounty hunter. After discovering Wataru might be the child of his first love, Maya, who was a Fangire, the truth was eventually confirmed by Wataru himself. Although conflicted, he couldn't carry his Shima's orders to eliminate Wataru, accepting him regardless of his Fangire blood.
- Megumi Aso - Keisuke's wife. At first he was at odds with Megumi because she disliked and was indeed jealous of Keisuke's overconfidence. But after she aided Keisuke's final battle against Bishop, when he suffered near blindness. Megumi was the person he first saw after his blindness disappeared and the two became closer, eventually getting married.
- Kengo Eritate: Keisuke's first encounter with Kengo didn't go well due Kengo's distaste in music. When Kengo decided to be his pupil, Keisuke still didn't fully accept him as he had planned to throw him away. This resulted in Kengo resenting Keisuke and his resolve to grow stronger until Keisuke's temporary fall and permission to use IXA got revoked in a karmic twist. Their odds would eventually end when Keisuke got his IXA back and asked Kengo for help to have Wataru to be relieved from his issue of his half Fangire blood.
- Mamoru Shima: Keisuke initially viewed Mamoru as nothing but a stone step for his justice and took the power of IXA. Although Keisuke still accepted Mamoru as his mentor, he still acted selfishly until the incident of W.A.O. framing which later changed Keisuke.
- Maya: During the incident of W.A.O. framing, Keisuke went to the past and accidentally met Maya. Maya was responsible to change Keisuke into better, including understanding music. Unfortunately for Keisuke, despite Maya became his first love, he was shocked to discover Maya is in fact, a Fangire.
