Kamen Rider Ryuki

Kamen Rider Ryuki (仮面ライダー龍騎) is a Japanese tokusatsu television series. The twelfth installment in the Kamen Rider Series, it was a joint collaboration between Ishimori Productions and Toei, and it was shown on TV Asahi from February 3, 2002 to January 19, 2003. The series marked the franchise's switch from Columbia Music Entertainment to Avex Group, which continues to produce music for the series today. The series aired along with Ninpu Sentai Hurricanger.

Story
Thirteen Card Decks (カードデッキ) were created for thirteen Kamen Riders. They form contracts with monsters from the mysterious Mirror World (ミラーワールド), a parallel dimension opposite to our own in which only the Kamen Riders can exist. The Riders draw on their monsters' strength in exchange for feeding them the life force of the creatures they destroy. The creator of the Advent Cards (アドベントカード) has only one rule: that there can be only one Kamen Rider. The others must be killed, and the sole victor will be granted a single wish, which leads to a conflict known as the Rider War.

All over the city, innocent people are being mysteriously abducted, never to be seen again. During his investigations of these incidents, Shinji Kido – an intern at the online news service ORE Journal – discovers one of the Advent Card decks at an apartment where every reflective surface has been covered by a newspaper. He is soon sucked into the Mirror World, discovering the terrifying truth behind the disappearances: people are being pulled through mirrors by the monsters of the Mirror World so that they may feed. He is about to be killed by a powerful dragon named Dragreder when he is saved by a Kamen Rider Knight: Ren Akiyama. Ren seeks to win the Rider War at all costs. He works with a young woman named Yui Kanzaki, who seeks her missing brother: the master of the Rider War, Shiro Kanzaki. Seeing Ren's strength, Shinji enters the Rider War, not for the prize, but so that he may protect innocent people from the threat of the Mirror World, and stop the senseless fighting between the Kamen Riders. With Dragreder as his contract monster, he becomes Kamen Rider Ryuki.

He discovers that some people cannot be saved and that he must sometimes fight to stop the fighting. The extent to which he must go if he wants his deepest wish to come true, and the sacrifices that he must make. In the very end, there can be only one Kamen Rider.

13 Riders
was written by Toshiki Inoue and directed by Ryuta Tasaki. It features the debut of the thirteenth Kamen Rider in the continuity of Ryuki: Verde. This special was first broadcast on TV Asahi on September 19, 2002. It was later released on DVD on July 21, 2003. The DVD also featured information on the characters, an interview with actor Arthur Kuroda, and an "interview" with some of the characters.

This television special is an alternate telling of the Kamen Rider Ryuki story. Shinji Kido's life, working as an employee at ORE Journal, takes a sharp turn after being pulled into the Mirror World by a Mispider. Luckily, he was saved by a Kamen Rider, Ryuki (Koichi Sakakibara, portrayed by Keiichi Wada). However, Sakakibara could no longer go on due to the severity of his injuries and passed his Card Deck to Shinji, allowing him to become the next Ryuki and defeat the monster. After meeting Yui Kanzaki and Ren Akiyama (Kamen Rider Knight), Shinji learns about the conditions of the Rider War, as well as of the other Riders participating. Unable to allow such a game of death to exist like his Rider predecessor, Shinji sets out to convince all the Riders to end the senseless fighting and put an end to the War. His pleas fall upon deaf ears as just about every other Rider (except for the already-defeated Riders Raia and Scissors) sets out to hunt down Shinji and his eventual reluctant ally, Ren. Eventually, Shinji's deck is destroyed and Ren dies, after passing on the deck for Kamen Rider Knight to Shinji. The special has two different endings which were voted on by the viewers via phone at the time of the initial airing: the voted-for-air ending (in which Shinji faces the surviving Riders on his own) and the alternate ending (a resetting of the Rider War).

One of them must win and become the last survivor before the sixth surviving Rider reveals himself. Amidst the impending chaos of the fight between the Riders, Shinji discovers an unbelievable truth about the relationship between Yui Kanzaki and the Mirror World, as well as discovering the existence of his Mirror World doppelganger, Kamen Rider Ryuga.
