Miyuki Tezuka

"When I made that prediction, the next Rider to go was actually you. But fate has changed."

- Tazuka revealing to Shinji that he was supposedly to die in his place according to his prediction.

Miyuki Tezuka (手塚 海之) is Kamen Rider Raia (仮面ライダーライア), a fictional character in the tokusatsu production Kamen Rider Ryuki. He is one of the 13 Kamen Riders the series revolves around.

Fictional character biography
He is a very accurate fortune-teller that believes in. He fights to stop the Rider war and change their fates, similar to Shinji, Kamen Rider Ryuki. Tezuka is among the few honorable and noble Riders in the series. Though he was given the left Survive card, he gave it to Kamen Rider Knight, even though that could have made him stronger. Tezuka was not the original deck holder that was chosen to become a Rider. The real chosen one was Yuichi Saito, an excellent pianist and dear friend to Tezuka, who had lost his ability to play when a mugger (later revealed to be Takeshi Asakura) broke his hands and ruined his ability to play. Kanzaki later appeared before Yuichi to offer the restoration of his hands if he becomes a Rider, but Yuichi refused and was eaten by the monster GuldThunder as a result. Taking the Card Deck, Tezuka later contracted Evildiver and became a Rider to avenge his friend by ending the Rider War.

While at a square performing Coin Fortune Telling, Tezuka notices Ren and reads his future before revealing himself as a Rider. Though he overpowered Knight but not intent on dealing the deathblow, Raia is shocked with Knight's suicidal counterattack. But after the fight, Tezuka tells Ren that he cannot win the Rider War because of the doubt in his heart. After seeing a vision of Knight being defeated by Kamen Rider Gai, Tezuka prods at Ren to know the truth behind him when he meets Shinji, who also intends to stop the fighting among the Riders. Tezuka aids Ryuki and Knight in dealing with Gai before he (Gai) is killed off by Ouja.

Raia died in the TV series during a fight against Ouja. When Ouja performed his Final Vent against Ryuki, Raia pushed him out of the way and took the attack instead. He died shortly afterwards due to his wounds. Being a very accurate fortune teller, he knew Ryuki was the one to be killed and let himself take the blow as he probably knew that Ryuki's better off being the one to stop the Rider war while Knight was better off with the Survive card. Before he was about to die, he sensed something off with Yui but he never got the chance to tell Shinji before dying in his arms. After Shiro restored time to its proper course after Yui's death, Tezuka was given a second chance in life with no memory of being a Rider and was seen doing tarot card readings on the corner of the street.

13 Riders
Tezuka's role in the 13 Riders special was slightly altered from the TV series. He was friends with Ren and had once loved Eri Aikawa, Ren's girlfriend. Though he became a Rider to help Aikawa, he still felt that the war between the Riders should be stopped. During the special, Raia was killed by Kamen Rider Verde and was the first Rider expelled from the Rider War.

OOO, Den-O, All Riders: Let's Go Kamen Riders
Kamen Rider Raia was part of a group of reinforcement riders led by Akira Date/Kamen Rider Birth to aid the primary riders in defeating the Rock Great Leader. All the Kamen Riders got on their bikes and performed the All Rider Break attack which destroyed the Great Leader.

Rider Time Ryuki
On the fourth day, Tezuka wakes Shinji and prepares the group to face off against Jun's team. Tezuka gathered Shinji and the new Kamen Rider Imperer and Verde. In the middle of their face off, they are interfered by Mirror Monsters. After they managed to survive, Tezuka met Jun's team and told his team that Jun's willing to co-operate and gives their Advent deck to him as a proof.

On the fifth day, Tezuka led the group to meet up with Jun's group to co-operate. But it was a ruse as he backstabbed the team by throwing Jun's team their Advent Decks, killing the new Imperer after he and Jun's team transformed. The reason why he betrayed his team is because he is in love with Jun and appears to be in a relationship together.
