The 13th Rider (13号ライダー, Jūsangō Raidā) is the twenty-seventh episode of Kamen Rider Ryuki. This episode marks the first appearance of Kamen Rider Odin, and a shocking revelation about Shiro Kanzaki's fate.


  • A young boy learns about the Rider War and steals Shinji's Deck before coming to realize that it is not all it is cracked up to be.
  • Yui, after a confrontation with Shiro in the Kanzaki Household learns that her brother is dead
  • The 4 remaining Riders meet a new Rider, claiming himself to be the "13th" Rider.


Yui feels even worse then previously now that Eri has begun to deteriorate. Ren tells her that he thought that hanging around Yui would give him an advantage in the Rider War. Ren hears and then chases a Mirror Monster who is trying to attack a young boy, Takuya. Takuya witnesses Ren change into Knight. A battle commences but the Mirror Monster escapes. Yui returns to the Kanzaki Household and runs into Shiro. He questions her interfering in the Rider Battle while she becomes upset that he does not seem to care whether Eri dies or not. She fears for Ren if Eri were to die. She goes into a frenzied rage and begins to rip the newspaper off all of the mirrors revealing hordes of Monsters. She then starts smashing all the mirrors yelling an empty threat to Shiro that she will become a Rider herself. Feathers appear around the two and one cuts Yui on the arm. Shiro threatens to erase Yui if she continues to get in his way and Yui declares that she no longer considers them siblings. She then runs out of the building holding a Shiro who appears to be fine with that and holds up a dark gold Card Deck. Ren hears from the hospital that the earlier deterioration of Eri has ceased before being faced by Takuya who witnessed his transformation. Takuya blackmails Ren into admitting that he can transform while also realizing that the Mirror Monster from before is still after Takuya. Ren brings Takuya back to the café where he meets Shinji. Ren leaves Takuya with Shinji and in the process reminds him about his debt. The next morning, Takuya questions Shinji about becoming a Rider and asking him to prove that he is one. Shinji reveals his deck and then proceeds and leaves it on the table. Goro interrupts the conversation and Takuya takes his opportunity and flees with Shinji's Deck. Ren, Goro and Shinji proceed to chase after Takuya. Takuya finds a mirror and attempts to transform after hearing the ringing sound in his ears. He is then intercepted by Darkwing and stopped by Ren. Ren takes back the Deck but after a conversation, Ren gives Takuya back the Deck, transforms into Knight and enters Mirror World. Although initially beating the Monster, Just as Takuya is about to transform, Knight begins to get beaten by the monster and Takuya learns how dangerous it actually is to be a rider. Shuichi enters Mirror World and attacks Knight who then changes his Survive form and uses a Final Vent on the monster while Zolda continues to fire on him. Takeshi also enters the world and knocks Knight off of his Rideshooter after destroying the monster. Watching the battle between the three, Shinji explains to Takuya the true nature of the Riders and that the Rider Battle cannot be simply switched off when he started to feel scared. Takuya returns the Deck to Shinji and he enters Mirror World. Ouja calls Genocider and proceeds to use a Final Vent before being interrupted by a New Rider. Reiko enters the café and tells her that Shiro is, in fact, dead and passed away in America about a year ago much to the horror of Yui. The new Rider tells the four other Riders to continue fighting and that the winner will fight him. He tells them that he is the 13th Rider to the mild enjoyment of Ouja and to the shock of Knight, Zolda & Ryuki.
