## Story

The story begins in 2008 as the Antlion Fangire begins to feed at an exhibit room until Megumi intervened as Nago arrives to slay the monster. However, during their struggle, the Mummy Legendorga suddenly resurrects and feeds on the humans before using his power to turn the Antlion Fangire into his slave to aid him in overwhelming Nago with the Arms Monsters watching the fight. While this occurred, Wataru Kurenai starts attending a local high school at Shizuka's suggestion after a welfare officer visited him and quickly befriends Natsuki Tsukue, who tries to get Wataru to join several clubs where he fails in each one while trying to ask her if she would like to start a violin club after hearing her play, she refuses out right.
Later that night, death row inmate Takashi Sugimura escaped from prison and the pursuing police officers by means of a dark power possessing him, with Nago going after him under advisement from Mamoru Shima to capture the fugitive with caution as he may be a Fangire. When Nago finds Sugimura, he chases the fugitive all the way to Wataru's high school and takes Natsuki hostage, but she is freed by the joint efforts of Wataru and Nago. However, the Medusa and Mummy Legendorgas appear to Sugimura's aid when he was being escorted back to jail, overpowering Ixa as Kiva arrives. They overpower the riders until another figure named Takato Shiramine appears, transforming into Kamen Rider Rey and driving the two Legendorgas off as they take Sugimura with them, waking him as their Lord.
At the cafe, as Shiramine explains the Legendorgas, Wataru finds that the current crisis started when Sugimura attempted to break out of jail by using the famous violinist Towa Sakakibara as a hostage in 1986 and broke the Legendorgas' seal. With this knowledge, Wataru asks the Arm Monsters permission to use Castle Doran's Time Door to go back in time to prevent Sugimura's actions. While trying to get Sakakibara to cancel her concert, he is stopped by Otoya, who was convinced he was a Fangire and tries to beat him. After another attempt to talk to her, Wataru is attacked by Yuri after Otoya tells her about him as the police arrive to arrest Otoya on the impression he is the criminal. Forced to take Wataru in a stolen police car, Otoya is shocked when Wataru recognized him as his father. Wataru attempts to prove himself with his cellphone and money before he and his father are both sent to Kanto West Prison where Towa is to perform as Sugimura takes her hostage to escape. But Otoya knocks out a guard named Sanjou so he and Wataru can get out of their cell to save Towa and restrain Sugimura.
After Wataru returns to his time under the impression he succeeded, Sanjou turns out to be Zebra Fangire that attacks Otoya before trying to kill Towa. But Yuri arrives to allow Otoya to kill the Fangire as Ixa, causing the chain of events where Sugimura escapes and uncovers the tomb of the Legendorga Lord, invoking the spirit within it. When Wataru returns to his time, he is targeted by people under the control of the Mummy and Medusa Legendorgas, with the Gargolye Legendorga overseeing their attack. Luckily, Otoya and Yuri arrive to aid their future children, later bonding with them before Otoya reveals that Towa Sakakibara is the stage name of Natsumi Tsukue, Natsuki's mother. Otoya is enjoying the present and its perks after disguising Wataru so he wouldn't be attacked, meeting up with Shiramine before he is distracted by a young woman named Sayaka as Shiramine tells Wataru that Kiva's destruction will soon come as Sayaka reveals herself as the Medusa Legendorga.
Becoming Kiva to fight the Legendorgas, he summons Buroon Booster which he uses to destroys the Mandrake Legendorga as the Arm Monsters arrive to aid Kiva in fighting the remaining three in both their true forms and in their weapon forms. However, as his friends drive the monsters off, Kiva is attacked by Rey who reveals that he is on the Legendorgas' side as he then takes the Aso girls hostage. Later at the cafe, after Otoya plays Natsumi's song to help Natsuki finally accept her mother, Rey-kivat arrives with orders to take Wataru to the Legendorgas' castle. After knocking his father out, Wataru arrives at the castle and is brought before Sugimura, who reveals himself to be the vessel of the Legendorga Lord Arc who was defeated by the original Kiva and uses his power to force Wataru's Fangire blood to manifest into Kiva's Flight Style. Under Arc's control, Wataru is forced to have Otoya relinquish his Ixa Knuckle as Nago arrives to help. But once he loses his Ixa Knuckle, Yuri and Megumi arrive after freeing themselves and use their time-respective Ixa Knuckles to fight the Legendorgas with Otoya managing to snap his son out of Arc's spell as the Aso girls kill the Medusa Legendorga.
Enraged, Sugimura decides to kill Wataru as they both assume their Rider Forms as the Ixa Knuckles are returned to Otoya and Nago who fight the Mummy Legendorga and Rey, respectively. Nago eventually gets the best of Rey, destroying him with the Ixa Judgement, while Otoya eventually destroys the Mummy Legendorga, even though his Save Mode helmet is heavily damaged in the process. While this occurred, Kiva is forced to assume Emperor Form to deal with the larger opponent, weakening him enough so he can be defeated by both of the Kurenai family Riders. However, Arc absorbs the power of the Legendorga race by sucking the eye on the moon into himself to become Legend Arc to kill them. Kiva then transforms into Emperor Form's Flight Style to fight Legend Arc in a battle across the city, until Castle Doran comes to Kiva's aid, finally allowing Kiva to perform a Rider Kick with enough force to slam Arc into the moon, leaving a gigantic crater and destroying him for good. After everything returns to normal, Otoya performs alongside his son on their violins at Wataru's school before he and Yuri return to their time. Once they left, Wataru is joined by Natsuki as the two perform a duet.

Rey's name comes from a Japanese word for "cold" (冷, rei).

#### Kamen Rider Arc

Takashi Sugimura (杉村 隆, Sugimura Takashi) is a death row inmate of the Kato West Prison (関東西刑務所, Katō Nishi Keimusho) in the year 1986, who becomes the host of the original Arc, whose original body was destroyed by the very first Kiva before his soul is sealed within a stone coffin enshrined in the prison that Sugimura broke while attempting his escape in 1986. As a result of being possessed, Sugimura remained youthful and unable to die after being executed before he made his escape in present-day before being taken by the Legendorga. Once taking full control over Sugimura's body, proceeds to get his revenge by killing the current Kiva. With the assistance of the mechanical monster Arc Kivat (アークキバット, Āku Kibatto), he can transform into Kamen Rider Arc (仮面ライダーアーク, Kamen Raidā Āku), the King of the Castle in the Demon World. As Arc, he wields the 4m long Arc Trident (アークトライデント, Āku Toraidento) and is the largest Kamen Rider to date at 3.2m tall (unless you count Kamen Rider J's jumbo formation). He can shoot a light bullet from the forehead. Through the use of the Wake Up Fuestle (which resembles Rey's Key Fuestle in the movie), Arc transforms into Legend Arc (レジェンドアーク, Rejendo Āku) by assimulating the demon-eye of the moon to obtain the full power of his race, growing wings and a second set of arms. In the process, Arc Kivat assumes Mecha Kivat (メカキバット, Meka Kibatto) mode as his persona cast comes off and yells, "Go to Hell." As Legend Arc, he can open up the giant mouth/eye in his chest known as the Dead Crusher (デッドクラッシャー, Deddo Kurasshā) and create the Ultima Black Hole (ウルティマブラックホール, Urutima Burakku Hōru) to perform the Ultima Dead End (ウルティマデッドエンド, Urutima Deddo Endo) finisher with the destructive power of 120t. Arc's name comes from a Japanese word for "evil" (悪, aku).

The Legendorga (レジェンドルガ, Rejendoruga) are the monsters of King of the Castle in the Demon World who serve the Legendorga Lord Arc in his attempt to take over the world. But their plan failed because of Fangire Race and the first Kiva who destroyed Arc's original body. But once their master's spirit is released into a new body in 1986, the Legendorga are revived in present-day to take their revenge on the current Kiva. One of the thirteen Demon Races (魔族, Mazoku) that also are composed of the Human, Kivat, Fangire, Wolfen, Merman, Franken, Doran, and Sagarc Races, the Legendorga all themed after legendary creatures and can convert other Demon Races into their kind.

The Mummy Legendorga is able to use his wraps to bind opponents. He can control an opponent using the Control Death Mask (コントロールデスマスク, Kontorōru Desu Masuku), the attack also serving as a means to feed on human victims. He is also able to enslave humans en masse with the aid of the demon-eye of the moon. He was destroyed by Otoya using the Ixa System.
* Medusa Legendorga (メドゥーサレジェンドルガ, Medūsa Rejendoruga): A Legendorga who assumes the human form named Sayaka (サヤカ). Armed with a gun and able to use the snakes on her head as weapons, also able to enslave humans like the Mummy Legendorga.

* Mandrake Legendorga (マンドレイクレジェンドルガ, Mandoreiku Rejendoruga): Able to turn any surface area to foliage, transforming any area into territory more suitable to him. Able to move faster and more agile in a plant-controlled environment, this ability was unable to keep him from being destroyed by a direct impact from Buroon Booster.
* Gargoyle Legendorga (ガーゴイルレジェンドルガ, Gāgoiru Rejendoruga): He battles Megumi in the Ixa gear as Rey arrives and freezes their legs so he could kill the girl with the Legendorga destroyed in the process. Furious at being used, the Gargoyle Legendorga tries to kill Rey only to die at his hand.
