Miyuki is psychic and it is a bit of a curse, as in he predicts his own death. He appears after Zolda does. The real chosen one was Yuichi, an excellent pianist, who had lost his ability when a mugger (later revealed to be Ohja) broke his hands and ruined his ability to play. Had Yuichi won, Kanzaki would restore his hands. Yuichi refused, and as such was eaten by a monster and Miyuki became a rider to avenge his friend. While at a square performing Coin Fortune Telling, Tezuka notices Ren and reads his future before revealing himself as a Rider. during fighting, he overpowered Knight but he didn't want to kill him, Raia is shocked with Knight's suicidal counterattack. But after the fight, Tezuka tells Ren that Ren cannot win the Rider War because of the doubt in his heart. After seeing a vision of Knight being defeated by Jun/Gai, Tezuka prompts 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, also helping Shinji retrieve his Dragreder Advent card back, since Jun stole it previously, before Gai is later finished off by Ohja. When Ohja 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. Shinji cares deeply for Miyuki and feels real bad, worse than for others, when he dies at the hands of Ohja. Evildiver was taken by Ohja to be used for a special monster. 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 readings on the corner of the street. In the 13 Riders special, 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.

Alternately, he can use his Copy Vent which can copy an opponents weapon. His Final Vent Hide Venom allows him to ride on Evildiver's back and ram into an opponent.
