- Woz: As it is written in this book, Sougo Tokiwa has encountered true legends, and is now on the verge of ultimate power.
However, his enemy has also obtained a similarly-vast power.
Now, the story of Sougo Tokiwa...
...enters its final chapter.
Somewhere in the city, a sprint runner is suddenly disappearing after his bad performance at an event. The news reported this, and Sougo who watches it, recognizes the victim as Nishimura, his ex-classmate. The news then mentioned that these days, many people also disappeared in mysterious circumstances. Junichiro Tokiwa arrives with their breakfast and said that they're must be spirited away, which gives Geiz idea that the culprit of this disappearance events is an Another Rider. When they're discussing this, a vibration in the time-space is happening, ushering Sougo, Geiz and Woz to investigate.
They arrive in a river, and soon enough a Time Mazine appears inside a distortion in time-space. Geiz recognizes the Time Mazine as an old model, from 2050 to be exact. Inside the mecha, here comes a blue Kamen Rider. As Sougo and Geiz prepare to fight, the Rider undoes his transformation and introduce himself as Michal Minato, Kamen Rider Aqua. He comes to the past to take Geiz and Tsukuyomi back to the future.
At another place in the city, Heure is running from something when his movement, and the world around him, are slowed. Heure knows this as Heavy Acceleration effect, and soon enough, Another Drive appears before him. As the Another Rider prepares to finish him, Heure casts his time power and stops it. He then escapes as Another Drive recovers easily. He ran away to Ora's hiding place, she is confused why Another Riders still exist when Sougo became GrandZi-O and united all the Rider powers. As they feel hunted by Swartz, Heure proposes to seek shelter.
Back in 95 DO, Woz introduces Minato as a Kamen Rider from the future, and he also came to the past before. Minato explains that Geiz and Tsukuyomi's presence in 2019 are ruining the future. He also states that changing the past is unforgivable. So, he ask again the both of them to come with him, back to the future. When Geiz is thinking about this, Junichiro says to Sougo that he has a friend waiting for him. Sougo and co are surprised at knowing his so-called "friends" are Time Jackers, Heure and Ora.
Heure explains that after Swartz took Ora's power, he's hunting them now. So he asks for shelter for the two of them. Geiz of course rejects them as they've been enemies before, but Sougo accepts them instead.
Back to the city, the scenery is darkened for some reason. In it, Nishimura was participating in a running event, and won easily. As he celebrates on his victory, an observing Swartz states that this is Nishimura's world now.
At some place in the city, Tsukuyomi is chasing Tsukasa Kadoya to ask him about herself and Swartz. Tsukasa explains that he and Tsukuyomi are the same, as they came from another world. He always had a suspicion about Swartz, and came to a conclusion that Tsukuyomi and Swartz's presence in this world are responsible in the rise of Oma Zi-O. He also thinks that this world is deemed worthy of destruction because of that. As Tsukuyomi asks how he'd destroy the world, as Decade's power is stolen by Swartz, Tsukasa says the loss of his powers were a minor nuisance. He then says that both of them don’t belong to this world before taking his leave.
In 95 DO, Junichiro forces Ora to cook some okonomiyaki as she wonders in annoyance where Heure goes. Sougo found him beside a river. Heure asks why Sougo accepts them in his house when they're enemies, and wonders if that is his kingly quality. Sougo only answers that the more are the merrier. When they're about to come home, they're alerted that Ora is suddenly missing. Heure then departs because he's worried about her.
Heure arrives in the scene of Another Drive's rampage and instantly attacked, but saved by Faiz Phone-wielding Tsukuyomi. Then Minato, who is looking for Tsukuyomi, arrives. Minato wants to fight but first he needs to gather his courage. He produces an underwear, calling it underwear for tomorrow, and then using water around him, transforms into Aqua. Aqua lay down the beating on Another Drive as Sougo and Geiz arrive to help. They transform into GrandZi-O and GeizRevive Shippu respectively, as Minato shocked at seeing Zi-O with a very different state than he knows. He left the Another Rider to the two of them as he take Tsukuyomi away for a talk.
Minato undoes his transformation and calls Tsukuyomi by her real name: Alpina. He then explain that Geiz's and Tsukuyomi's presence are responsible in the rise of Sougo as the demon king. Tsukuyomi tries to argue that they both are making sure that Sougo won't become Oma Zi-O, but Minato counters that very intention ensures that Sougo will become Oma Zi-O.
Back in the battle, Another Drive fought savagely and troubling both riders with his Heavy Acceleration. Heure helps them with time stop, and they finally defeat the Another Rider. But, in the midst of explosion, Ora stands?! As they watch in confusion, Swartz arrives. He transforms into Another Decade, and with his dimension wall, transport Sougo and Geiz to an unknown place.
Swartz states that this is his world, and summons Kamen Riders G4, Rey, Dark Ghost and Fuma to do his bidding. Swartz blasts Sougo and Geiz, then sics the evil Riders to fight them...
Episode Tropes:
- Apocalypse Maiden: Tsukuyomi is one according to both Tsukasa and Michal. They both think that due to her being a Time Master from the future and another dimension messing with the past is causing time-space distortions. Tsukasa also thinks that Sougo is one and believes that he's the direct cause of the distortions.
- Both Sides Have a Point: Geiz and Michal argue over whether it was right to change the past ends with both sides having merit. Geiz is right that Michal doesn't understand the situation and Oma Zi-O is an invincible but deluded madman that rules over the world with an iron-fist so there really wasn't any other option left. But Michal is right that their actions are wrong as they have created massive time-space distortions as seen in the story.
- Break the Haughty: Heure states that he used to see himself as above time and looked down on Sougo only to now depend on him for safety and calls himself pathetic as a result.
- Escort Mission: The reason why Michal is present in 2019 is so that he can bring Geiz and Tsukuyomi back to the future.
- Given Name Reveal: Michal reveals to Tsukuyomi that her real name is Alpina.
- Mythology Gag: Before battling Another Drive, Minato pulls out the pair of underwear that he received from Eiji in MegaMax to give himself courage. A guitar riff of the TaToBa jingle and the sound of a Core Medal reinforce the connection.
- Red Herring: At first, Another Drive seems to be the missing athlete that was kidnapped by Swartz. But when GrandZi-O and GeizRevive defeated "him", Ora emerges from the explosion instead.
- Samus Is a Girl: Another Drive turns out to be Ora.
- Security Blanket: Minato has been keeping the underpants Eiji gave him in Movie War MegaMax on his person to act as one of these.
- Self-Fulfilling Prophecy: Michal says that Tsukuyomi and Geiz's presence in Sougo's life ensures that he will become Oma Zi-O because they come from a future where Oma Zi-O exists.
- Wham Shot:
- It turns out the host of Another Drive is none other than Ora herself.
- Swartz, as Another Decade, summons G4, Fuuma, Dark Ghost, and Rey to fight for him.
