Kamen Rider Kiva (Earth-71)
KR-Kiva Poster (Climax Scramble).jpg

Kojou Akatsuki (暁 古城 Kojou Akatsuki?) is a shy 16 year old college student who teams up with Kivat-Bat the 3rd to fight against the Fangire race and protect humanity as Kamen Rider Kiva (仮面ライダーキバ Kamen Raidā Kiba?, Masked Rider Kiva), initially because the Bloody Rose told him to "fight". He was conceived the half-human/half-Fangire child of Otoya Akatsuki and the Fangire Queen Maya, inheriting the mantle of Kiva from his mother. But in time, Kojou learns of his family legacy and nature as a Fangire, as well as desiring to become someone strong like his father.


A college student who loves music greatly, Kojou Akatsuki was initially a shut-in whose only friends were Kivat-Bat the 3rd and Yukina Himeragi. Having had little interaction with others, Kojou could easily become emotional, something that Kivat-Bat the 3rd constantly warned against.

Although at first glance Kojou seemed weak, he is actually quite tough in his own right, managing to live on his own as a small child without any parents to take care of him. Partly due to not having a guardian though, Kojou had a slight lack of common sense, which only worsened his unpopularity. His tendency to bring odd ingredients for violin making has been the subject of ridicule by many, with even Yukina feeling disturbed by it. 

Being a pacifist, Kojou would rather not use violence to resolve a situation, opting to instead talk things out with his foes. However, this stance also caused Kojou to become something of a pushover, having difficulty turning down requests. Worse, it also made Kojou not have the courage to tell others what they need to hear, fearing they will become disheartened.

While initially distraught once learning of his true heritage, Kojou eventually learned to accept himself for who he truly is and realized that not all Fangires are evil. This also convinced him that humans and Fangires can co-exist, so long as they will it.

He also learned how to socialize more with others, being accepted by his neighbors when he faced them in a mature manner. Though he felt disheartened many times in the series, Kojou ultimately learned to believe in himself, as his father Otoya had believed in him.

  • Punching Power: 6 t.
  • Kicking Power: 8 t.
    • Darkness Moon Break: 30 t.

  • Maximum Running Speed: 100 m. per 6.5 sec.

Kiva Form (キバフォーム Kiba Fōmu?) is Kiva's base form accessed with Kivat alone.

Kamen Rider Kiva is composed of the following parts:

  • Kiva Persona (キバ・ペルソナ Kiba Perusona?) - The head.
    • Demon Emperor Stone (Blue Stone) (魔皇石 (碧石) Ma Ō Seki (Ao Seki)?) - The blue-green jewel on the forehead. It amplifies Kiva's Demon Emperor Power (魔皇力 Maou Ri~yoku?) by several to tens of times. In this world, a blue Demon Emperor Stone is much more valuable than a crimson/red Demon Emperor Stone (such as those found in Kiva's Arms Weapons). It can accumulate and amplify demonic energy and serves as a restraint to prevent the demon energy from exploding.
    • Guardian Crown (ガーディアンクラウン Gādian Kuraun?) - The red 'bat head'/guard plate section on the forehead that houses the Demon Emperor Stone. It serves to protect the Demon Emperor Stone. Its red coloration is due to the Demon Emperor Stone's influence.
    • Crown Sonar (クラウンソナー Kuraun Sonā?) - The red sections on top of the Omni Lens. Its coloring is due to the influence of the Demon Emperor Stone. This crimson crown can emit ultrasonic waves to utilize echolocation to grasp surroundings if Kiva's view is obstructed. In can collect information such as enemy position up to 5000 meters away.
    • Coolant Silver (クーラントシルヴァ Kūranto Shiruvu~a?) - Silver sections embedded behind the Crown Sonar. They are cooling boards that prevent the user's brain from being destroyed due to the vast amounts of demonic power amplified by the Demon Emperor Stone. It is made of Trysilvania Silver (トライシルバニア銀 Toraishirubania Gin?), which has the power of silver (銀の力 gin no chikara?) to suppress demonic power from exploding. It has five heat-dissipating ducts on each side of the head to cool down heat energy swirling within the hemet.
    • Omni Lens (オムニレンズ Omuni Renzu?) - The eyes. They are visual amplification devices that can obtain visual information at a distance of 500 meters forward and at a 220° angle. It also has an X-ray function that allows Kiva to see through 10 meter-thick steel plating. A nanoscope function is also incorporated, allowing Kiva to detect extremely small objects such as bacteria.
    • Wild Nose (ワイルドノーズ Wairudo Nōzu?) - An olfactory amplification device located between the eyes. It gives Kiva detection abilities equivalent to a dog's, allowing Kiva to obtain a sense of smell one million more times than a human. The Wild Nose can track a Fangire's location by sniffing out their odor and footprints.
    • Omni Phone (オムニフォン Omuni Fon?) - Hearing amplifiers. Its sensitivity can be raised according to the wearer's will, and if sensitivity is raised to the maximum, Kiva can discern the sound of a needle falling up to 3km away.
    • Gau Crusher (ガウ・クラッシャー Gau Kurasshā?) - The silver mouth plate. It is actually a set of metal tusks crafted out of sharpened Lucifer Metal (ルシファーメタル Rushifā Metaru?). It has a jaw force of 1.2t and can chew through a metal ball that is about 8cm in diameter. An air purifier is installed inside to decompose and purify toxins. It also takes in and purifies all substances necessary for breathing from the surrounding air; this function even works within a vacuum state.
  • Darkness Choker (ダークネス・チョーカー Dākunesu Chōkā?) - The black choker device on the base of the neck area. Among monsters, a necklace that imitates a demon's face is a favorite decoration of those with power. Among lower monsters, it is said that they simply look at this ornament, meaning that it serves no real functional purpose and is just for decorative purposes.
  • Bloody Lung (ブラッディラング Buraddi Rangu?) - The red chest segment. It is where Kiva's power is stored. its red coloring is due to the fact that this is where the most demonic power is accumulated. It sends power to the whole body via its black blood vessels that have been branched in layers.
  • King Singlet (キングシングレット Kingu Shinguretto?) - The chest armor. It is a strong auxiliary armor that protects Kiva's body, and at the same time functions as a restraint to suppress potential explosion of demonic power. It is made out of Lucifer Metal and has been coated in Trysilvania Silver to further suppress demonic power.
  • Ptera Plate (Shoulders) (プテラ・プレート (肩) Putera Purēto (Kata)?) - The shoulder armor. They are restraints that suppress Kiva's power amplification. Kiva's power, which has been activated by Kivat and amplified by the Demon Emperor Stone, is immeasurable and could potentially cause Kiva to self-destruct. Hence the need for restraints.
  • Catena (カテナ Katena?) - Chains wrapped around the shoulders and the right leg. It is crafted out of Lucifer Metal and is coated with Trysilvania Silver. Furthermore, a seal has been engraved on its surface to prevent an explosion from demonic power overload. (Note: 'Catena' is Italian for 'chain'.)
  • Doran Mail (ドランメイル Doran Meiru?) - Kiva's bodysuit. It is a tough inner suit made from the leather of the Black Dragon Gaora Doran (ガオーラ・ドラン Gaōra Doran?), and has been processed by using the same dragon's fangs. It protects the wearer from extreme weather conditions, whether it be burning hot or freezing cold. It is extremely difficult to pierce with currently existing bullets and knives.
  • King's Breath (キングブレス Kingu Buresu?) - Demonic power amplification bracelets located on the wrists. Red Demon Emperor Stones are embedded. The power of the stones amplifies Kiva's power several times giving Kiva superhuman strength. It has been coated with Trysilvania Silver for easier control.
  • Blood Vessel (ブラッドベッセル Buraddo Besseru?) - An energy flow path used to distribute Kiva's power across the whole body. By using Kivat's body as the 'core', it has the function of efficiently circulating the power of the demon throughout the whole body.
  • Sylvania Knee Guards (シルバニア・ニーガード Shirubania nī Gādo?) - The kneecaps. Not only do they protect Kiva's knees, but they also serve as a resistor to control the demonic power flowing into the feet.
  • Hell's Gate (ヘルズゲート Heruzu Gēto?) - The metal right leg restrainer. It is forged out of Trysilvania (トライシルバニア Toraishirubania?). This restraint, dubbed the Gates of Hell (地獄の門 Jigoku no Mon?), opens up when Kiva utilizes the Wake Up Fuestle, allowing the Catena chains to open up, fully opening Hell's Gate. When opened, it resembles bat wings, and serve to ensure that kicks from a high altitude land on targets. Its tip is made of Lucifer Metal and is as sharp as a diamond. Its insides have been dyed crimson due to the influence of the Demon Emperor Stones. It also plays the role of power release plates, diffusing and emitting any power that rebounds during impact.
    • Demon's Mount (デモンズ・マウント Demonzu Maunto?) - The red parts encasing the right leg. They are fixtures that hold the demon stones in place while keeping the right leg from exploding. Originally, it had a silver coloration due to it being crafted out of Trysilvania, but has been dyed red due to the influence and power of the stones. it has been designed to invoke the face of the legendary Demon King's face, which has been handed down between monsters.
    • Goldie Vessel (ゴルディ・ベッセル Gorudi Besseru?) - A golden Blood Vessel that flows demonic power through the Demon Emperor Stones of the air, sea, and land via bottleneck effect.
    • Demon Emperor Stone of the Air (Blue Stone) (宙の魔皇石(碧石) Sora no Ma Ō Seki (Ao Seki)?) - The top stone located on the upper right leg. It amplifies demonic power with the power of the cosmic spirit (宇宙の精霊 uchū no seirei?). After passing through the Blood Vessel, the first area where demonic power is accumulated, demonic power is sent through the Demon Emperor Stones. From there onwards, power is amplified twice more than usual, allowing Kiva to utilize great power.
    • Demon Emperor Stone of the Water (Blue Stone) (水の魔皇石(碧石) Mizu no Ma Ō Seki (Ao Seki)?) - The middle stone located on the lower right leg. It receives demonic power from the Demon Emperor Stone of the Air and further amplifies it. It is said that the water spirit (水の精霊 mizu no seirei?) resides in here, and with its power, the demonic energy is twice amplified. At this point, demonic energy has been amplified four times.
    • Demon Emperor Stone of the Land (Blue Stone) (地の魔皇石(碧石) Chi no Ma Ō Seki (Ao Seki)?) - The lowest stone located on the right foot. With the help of the land spirit (地の精霊 ji no seirei?), amplified energy is amplified to the maximum. The reason for dividing the amplification process into three stages is a precaution against the possible destruction of Kiva during the process. At this point, demonic energy has been amplified by a factor of eight, giving Kiva enough energy to execute the Darkness Moon Break.
    • Devil's Mouth (魔斬口 Mazankō?) - The right foot. A red Demon Emperor Stone is fitted on the sole, where demonic energy flows out of during the Darkness Moon Break. By releasing energy amplified by all three Demon Emperor Stones at once, tremendous destructive power is unleashed.
  • Balancer Anklets (バランサー・アンクレット Baransā Ankuretto?) - The ankle armor. The right leg's Balancer Anklet is hidden within Hell's Gate. The power contained within is far greater than ordinary people. While keeping the power balance with the right leg evenly, it can deliver an explosive destructive power of about 8 tons even with a regular kick in a restrained state.

Kamen Rider Kiva has the following finishers:

  • Darkness Moon Break (ダークネスムーンブレイク Dākunesu Mūn Bureiku?) - By having Kivat blow the Wake Up Fuestle, the Catena chains binding the Hell's Gate (ヘルズゲート Heruzu Gēto?) on Kiva's right leg break open. Kiva then performs a powerful kick with an impact of 30,000 kg, enough to leave a crater in the shape of a bat's wings (Kiva's insignia) on any surface upon contact; the glass body of a Fangire shatters almost instantly. Kiva can also perform a stronger variation of the Darkness Moon Break when engulfed in Castle Doran's fire. When the Darkness Moon Break is performed, day turns into night and a crescent moon appears in the sky.
  • Bloody Punch (ブラッディーパンチ Buraddī Panchi?) Kiva jumps into the air and strike the opponent with a strengthened punch.

  • Kicking Power: 32 t.
    • Emperor Moon Break: 150 t.

  • Maximum Running Speed: 100 m. per 3 sec.

Emperor Form (エンペラーフォーム Enperā Fōmu?), also referred to as the Golden Kiva (黄金のキバ Ōgon no Kiba?), is the true form of Kiva accessed with Tatsulot. By pulling the switch on Tatsulot's head, Kojou can activate Tatsulot's Imperial Slot (インペリアルスロット Inperiaru Surotto?) and activate one of several "Fever" finishing attacks through a roulette system. With this form, Kiva can destroy both the body and the soul of a Fangire. Because of its ability to destroy Fangire souls, Kojou has gradually abandoned using his other forms in favor of Emperor Form.

In episode 39 this form went into Emperor Form (Rampage) (エンペラーフォーム(暴走) Enperā Fōmu (Bōsō)?), the Fangire influenced version of Emperor Form. When Kojou's Fangire blood is awakened by the Swallowtail Fangire he temporarily became a Fangire version of Emperor Form gaining the Fangire's signature stained glass appearance and becoming a berserker attacking friend or foe. This caused Kojou to go into isolation until encouraged to fight again.

Kamen Rider Kiva Emperor Form is composed of the following parts:

  • Emperor Persona (エンペラー・ペルソナ Enperā Perusona?) - The helmet. With a huge crescent-shaped tiara on his forehead and a mask with Kiva's original ominous face, Fangire who sees the mask will fear Kiva and lose the will to fight.
  • Hell's Breast (ヘルズブレスト Heruzu Buresuto?) - The chest plate. The three exposed Demon Emperor Stones are fixed onto an enlarged Demon's Mount. It has a Goldie Vessel in the center that efficiently amplifies the demonic power throughout Kiva's armor. The Demon's Mount, which is larger than it was when it was on the right leg, is used to safely control the power of Kiva. It is always open and is colored red by the mighty power of the Demon Emperor.
  • Imperial Armor (インペリアルアーマー Inperiaru Āmā?) - The golden armor. Lucifer metal on Kiva's body shines gold under the influence of the Demonic Power, and its defense is increased to be 5 times than normal. The material is Lucifer Metal, which is different from Lucifer Gold (a metal used for decoration that efficiently circulates the power of the Demon Emperor, which is used in Kiva Persona and Garulu Saber). Lucifer metal, which forms the Kiva armor, has the property of discoloring in response to the release of the wearer's immense Demonic Power. The armor of Kiva's armor is truly an iron wall, so robust that it can't be hurt even being in the center of a nuclear explosion.
  • Bloody Wing (ブラッディウイング Buraddi Uingu?) - The cape. It allows Kiva to fly high into the sky by becoming a wing when executing the "Emperor Moon Break". The amplified Demonic Power is circulated around here, causing it to be dyed bright red. The strength is comparable to Lucifer Metal due to being made of fiber that has been processed from the great dragon Castle Doran.
  • Demon Emperor Stone (魔皇石 Ma Ō Seki?) - The three Demon Emperor Stones: air, water, and earth which were sealed on the right leg of Kiva form, have been unsealed and moved to the center of the body. With the power of Kiva's armor that has been finally awoken, it has become possible to control the immense power of the emperor dwelling in the three monument stones that had been dangerous to open all the time. By placing it in the center of the body, it is possible to spread the enormous power of amplified Demonic Power throughout the body and even with a normal kick, it is possible to produce destructive power exceeding that of Darkness Moon Break.
  • Doran Mail (ドランメイル Doran Meiru?) - The undersuit that holds the power of Kiva Emperor Form is the same Doran Mail as Kiva Kiva Form, but in response to the final awakening, the blood vessel patterns fluctuate and changes into a pattern that is convenient for the flow of the amplified Demon Power.
  • Goldie Shoulder (ゴルディショルダー Gorudi Shorudā?) - The shoulder armor made of Lucifer's Metal, the shoulder pad has a sharp tip and has a hardness that is strong enough to cause fatal injury to the opponent just by ramming them.
  • Silver Knee Claw (シルヴァ・ニークロー Shiruvu~a Nī Kurō?) - A knee pad made of Lucifer Metal that protects the knee, and claw can be deployed to knee enemies.
  • Lucifer's Knife (ルシファーズナイフ Rushifāzu Naifu?) - The Lucifer Metal spikes on the heels that are polished to the utmost so that the steel can cut effortlessly upon touch. The finisher Emperor Moon Break is activated by pouring the Demonic Power into them and moving them to the soles. The destructive power of the finishing attack is 150t.

Bloody Rose

Bloody Rose

Main article: Bloody Rose

A unique violin, the Bloody Rose (ブラッディ・ローズ Buraddi Rōzu?) was created by Otoya and Maya as the "ultimate violin", later rumored to be a product of Otoya selling his soul to the devil himself, which is not entirely false, in a sense. The Bloody Rose only sounds whenever a violent Fangire is detected in the area, its music only heard by Kivat and Kojou, who hears it as a voice commanding him to "Fight", as it pinpoints the exact location the Fangire could be found. When played, the Bloody Rose can also disrupt a Fangire's activity. However, the Bloody Rose is sympathetic to Wataru's mentality as it cracked when he fell into a deep depression. However, after repairing it, Kojou learns the Bloody Rose holds the desires of his father, placing in it his own desire which allowed him to assume Flight Style.
