Koichi Kurenai

Koichi Kurenai is Kamen Rider Emperor King. He is the younger brother of Wataru Kurenai and the half-brother of Taiga Nobori.

Fictional character biography
Left by Maya as a child to protect him from the retribution she would face, Koichi and Wataru lived in the European-style manor that his father lived in. His brother is allergy to the "world".

Forms
Emperor King has multiple forms that provide him with different weapons and abilities. Emperor King's motif is that of a vampire, with his final attacks inherited from Maya. However, unlike his predecessor, Koichi's nature as a human-fangire hybrid leaves him unable to fully utilize Emperor King's full power with the Catena Chains. Additionally, Tatsulot and Zanbat serve as restraints to keep the power of Emperor King from taking complete control of Koichi.

Emperor King Form is Emperor King's default form, accessed through a bite from Kivat, who status determines Emperor King's ability in a battle. He is able to see in the dark with his visor called the Omnilens. In this form, Emperor King can use any of the Fuestles, with the Wake Up Fuestle to open up the Catena Chains on his right leg known as the Hell's Gate made of Lucifer Metal so Emperor King can use his Darkness Moon Break attack. The kick has 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.

Emperor King 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.

In Kamen Rider Battle: Ganbaride, Kiva is able to perform the Bloody Punch, which involves Kiva jumping into the air and striking the opponent with a superman punch.

Emperor King Form's ending theme is entitled "Destiny's Play". Arms Monster Forms=

DoGaBaKi Form, shortened from "Dogga/Garulu/Basshaa/Kiva Form", is Emperor King's rarely seen form, accessed by the summoning of all three Arms Monsters. In this form, Emperor King's left arm turns into the Garulu Arm, his right arm turns into theBasshaa Arm, and his upper body turns into the Dogga Breast. In this form, Emperor King can use all three Arms Monster weapons at once and the Darkness Moon Break. However, due to the danger it presents to Emperor King and the Arms Monsters, Emperor King can only assume this form for five minutes before its power becomes lethal to him.

In Kamen Rider Battle: Ganbaride, Kiva in DoGaBaKi Form is able to perform the Gate Crasher - A powerful slash with the Garulu Saber enforced from the brute strength of DoGaBaKi Form.

Resulting from infusing his own desire into the Bloody Rose, Hayato's Fangire nature is triggered as Emperor King transforms from Emperor Form into Flight Style, a dragon-like form called the Emperor Bat which is similar to the Fangires' ability to become Sabbats.

In Kamen Rider Kiva: King of the Castle in the Demon World, Arc uses his Legendorga baptism to turn Wataru form a Human/Fangire hybrid into a full Legendorga by forcing him to assume the form in an attempt to kill his father, Otoya Kurenai, though his father managed to bring him back with Wataru reverts back to his Human/Fangire hybrid. Wataru later re-accesses Flight Style to defeat the giant Rider. Ironically, the Legendorga version of Flight Style has a darker colour scheme as it's golden accent turns brown and the red on his wing becomes maroon.

Flight Style uses the blades on his wings called the Sonic Claws to perform the Demon Pliers attack and breathes the Hell's Flame from his Big Jaw. These abilities come into play for its finishing attack, the Bloody Strike.

Bloody Rose


A unique violin, the Bloody Rose 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 Wataru, 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 sympathic to Wataru's mentality as it cracked when he fell into a deep depression. However, after repairing it, Wataru learns the Bloody Rose holds the desires of his father, placing in it his own desire to assume Flight-Style.
