2007: DenLiner Crash! (2007:デンライナー・クラッシュ! Nisen-nana: Denrainā Kurasshu!) is the thirty-ninth episode of Kamen Rider Zi-O. It is the first part of the Kamen Rider Den-O tribute arc. Thus, it features the return of Yuto Sakurai, portrayed by Yuichi Nakamura, the four Taros and Deneb voiced by Toshihiko Seki, Kōji Yusa, Masaki Terasoma, Kenichi Suzumura, and Hōchū Ōtsuka respectively, and the full debut of the Den-O Ridewatch. It also features the first look of GrandZi-O and the GrandZi-O Ridewatch.


The train that travels through time, the DenLiner, suddenly makes an emergency stop! The Imagin that reside within all exit the train too! They have come to 9 5 Do to have Junichiro fix their broken DenLiner. "But, I just fix home appliances..." he replies. Furthermore, Ora has created Another Den-O after finding a suitable target: a man who is jealous of his sister's lover...

Continuity and Placement


In a field, Sougo as GrandZi-O is facing Another Den-O. He utilizes the final form's ability to summon Kamen Riders: Build, Kuuga, OOO and Gaim to attack the Another Rider as Woz exclaims that Sougo is now finally inheriting all Heisei Riders' power. In the meantime, two mysterious persons are observing the battle, noting that finally, the Demon King is here.

"Apologies, it seems I may have spoiled a future of what's to come. Please forget what you saw. However two individuals seems to have their eyes set on Sougo Tokiwa from the shadows. Just who would they might be? Let us return to the story, to when two Watches remained have yet been collected..."

Meanwhile, the train of time DenLiner is crashing at 2019 Japan, with the Imagins bickering...

"They are the ones who lent their power to Kamen Rider Den-O. The next power that Sougo Tokiwa must obtain is... Kamen Rider Den-O."
Black Woz[src]

The Imagins are crashing at 9 5 DO when they request Junichiro Tokiwa's aid at repairing the DenLiner. It seems that the uncle is considered the best repairman of this era. Junichiro said that he only repairs clocks, but Urataros explains that the DenLiner is just like a giant clock, inciting his curiosity. Junichiro is still hesitating, however, but Ryutaros possesses him and alongside the other Imagins, they go to DenLiner, with a concerned Sougo in tow.

Somewhere in the city, Ora meets Heure to discuss the situation regarding Sougo now, as he only needs 2 more Ridewatches to ascend as Ohma Zi-O, foiling Time Jackers' plan. Ora claims that she has a way to deter this, however.

At a cemetery, Takuya Endo is seen mourning at his sister's gravestone. He is then approached by Yukihiro Osumi, but Takuya lashes at him, saying that Yukihiro is the one responsible for his sister's death. Suddenly, Ora appears and offers Takuya a chance to change the past, but for that, he must help her steal the DenLiner. Takuya is transformed into Another Den-O and escapes with Ora as Yukihiro can only cower in despair. Then, a Mole Imagin appears before him. The Imagin asks what Yukihiro's wish, and he answers that he wants to help Takuya. With that, the contract is forged.

At the DenLiner, Junichiro notes that it indeed operates just like a giant clock. So, he will endeavor to repair it. Suddenly they're attacked by Another Den-O. Sougo, Geiz and Woz transform into Zi-OTrinity... only to intercepted by ZeroLiner, driven by Yuto Sakurai and Deneb. Sougo confuses Yuto as Kyosuke Kiriya, but he transforms into Kamen Rider Zeronos to defeat Sougo, that he proclaims as Demon King. After a brief scuffle, they find that Another Den-O is still attacking the DenLiner, so they combine their attack to defeat him. The Another Rider reverts back into Takuya and Ora helps him escape.

Back in 9 5 DO, Yuto explains that he and Deneb are from the future. They seen the rise of Ohma Zi-O after Sougo collects all 20 Ridewatches, so they travel back in time to stop him. After that, Yuuto and Deneb leave the shop. As Sougo is confused, Momotaros possesses Geiz because he wants to defeat Another Den-O by himself. He went outside with a panicked Tsukuyomi chasing him.

Meanwhile, Sougo is still brooding. He initially wanted to collect all Ridewatches to defeat Ohma Zi-O himself, but as Yuuto said, he will become the Demon King instead in that event. He asks Woz if obtaining that power will help him defeat Ohma Zi-O. Woz states that the only power that can match Ohma Zi-O is Ohma Zi-O itself, and assures him that he will surely obtain it after the ultimate power. Sougo is left confused, but soon had to leave with Woz for aiding Geiz.

Another Den-O is on a rampage to find the DenLiner. Momotaros, in Geiz's body, arrives to fight, but he doesn't know how to transform using Ziku Driver. Tsukuyomi helps him, and he transforms into GeizRevive Goretsu. He fights Another Den-O valiantly, but the Mole Imagin disrupts him as he wanted to fulfill Yukihiro's wish. Then, Sougo and Woz arrive, wondering about the Imagin. Yuto also arrives and challenges Sougo once again, but the future Demon King states that he still wants to ascend no matter what, as he wants to become the nicest Demon King. Sougo transforms into Zi-OTrinity, dragging Momotaros inside the Fusion Rider as he had possessed Geiz.

Sensing Momotaros inside Zi-O, Yuto transforms into Zeronos Vega form and a free-for-all battle begins. In the end, Zi-OTrinity defeats Zeronos, but as he moves to Another Den-O, the repaired DenLiner arrives. In the midst of confusion, Another Den-O hijacks the train of time and he escapes into another point of time. The Mole Imagin, realizing that Yukihiro's wish is fulfilled, then goes inside of his contractor.

Zi-OTrinity cancels the transformation and Geiz immediately grapples with Momotaros in annoyance. Sougo notes that they don't know the arriving point of DenLiner, as Woz answers that they need the Den-O Ridewatch for that. Momotaros gives him said Ridewatch as he and his fellow Imagin had already created it, and it resonates with other 19 Heisei Ridewatches to form the GrandZi-O Ridewatch, as the others (except Woz and Momotaros) witness in horror...

  • This episode concludes the movie Kamen Rider Heisei Generations FOREVER is non-canon for the following reasons below:
    • Geiz and Tsukuyomi not recognizing the DenLiner during the start of the episode. However, in the movie, the DenLiner rescued them when the two were riding in damaged Time Mazines.
    • Sougo and his friends don't remember the Taros and vice-versa. After the DenLiner crashed, Urataros spotted Geiz & Tsukuyomi, referring them both as "local folk", not recognizing Geiz who was there during Ryotaro's cameo.
    • When Zi-O & Geiz fight the 2019 version of Another Den-O, they don't seem to recognize the Another Rider as they previously fought a previous version from 2007. Zi-O was able to figure the Another Rider's name by reading "DEN-O" labeled on his suit.
    • However, this leaves the mystery of how the Kuuga & W Ridewatches was achieved, which both appear in the series in episode 21, nearly one month after the film's release.
  • As with Fourze, Wizard, Hibiki, Kiva and Kabuto tribute arcs, Takeru Satoh does not return as Ryotaro Nogami, though he previously had made an appearance in Kamen Rider Heisei Generations FOREVER.
  • Another Den-O makes his first televised appearance as the 2019 version created by Ora since his previous appearance in Heisei Generations FOREVER.
  • This episode marks Yuichi Nakamura’s second appearance in a tribute arc, though he is reprising an entirely different character.

Kamen Rider OOO suspending in the air.

  • At the start of the episode, when Yuto watches the battle far away, OOO is seen to be strangely suspended midair in the middle of his finisher as Gaim moves in to attack Another Den-O, even though OOO's attack was completed moments ago before Gaim was even summoned.
    • In the following episode, this is later revealed to be one of GrandZi-O's abilities, to allow him to reverse Riders and suspend them in midair until he reactivates them. However in said episode, GrandZi-O reverses OOO's finisher then allows it to resume after using Build's Fullbottle Buster finisher then summons Gaim after said both finishers were complete, proving that this shot is indeed still an error. 
  • The Riders summoned by GrandZi-O are likely coming from their original timeline, as the background during the Legend Riders battle are briefly shown while being summoned.
  • Despite Sougo collected most of the Ridewatches, he has yet to obtain the Drive Watch and is using the Ridewatch that was previously in Ohma Zi-O's possession.
  • The Riders summoned by GrandZi-O relate to two aspects that have happened in the show.
    • Kuuga and Build - Riders whose respective Ridewatches were first used by Zi-O.
      • Kuuga - First First Phase Heisei Era Rider whose powers were used by Zi-O.
      • Build - First Second Phase Heisei Era Rider whose powers were used by Zi-O.
    • OOO and Gaim - Ride Gadgets based on an aspect of their's appeared.
      • OOO - Taka Ridewatch.
      • Gaim - Kodama Ridewatch.
