All spoilers for Kamen Rider Zero-One will be unmarked. You Have Been Warned!

Kamen Rider Zero-One: REAL×TIME is the winter film for Kamen Rider Zero-One, double-billed with Kamen Rider Saber's own winter film, Kamen Rider Saber: The Phoenix Swordsman and the Book of Ruin.

Set three months following the end of the series and the Stage Show, Kamen Rider Zero-One: Final Stage, large-scale terrorist attacks occur worldwide simultaneously, heralded by the appearance of a man calling himself S who, aided by his group of believers, proclaims that he will destroy the world in order to build a paradise. Now, as turmoil, death and destruction consume the world, Aruto, Is, Fuwa and many others must find the truth behind the ongoing attacks while defending humans and Humagears alike from S's clutches in 60 minutes' time.

Tropes featured in the film

• And You Thought It Was a Game: S manages to get so many Abaddon goons to follow him around by disguising the central network they operate on as an MMO. And sure enough, all the typical tropes about digital avatars vs. reality (except for that one) are revealed to ensue as a result.
• Back from the Dead: The original Is comes back, thanks to the memory she stored in the Zero-Two Driver.
• Back-to-Back Badasses: Aruto and Is engage S' forces side by side as Kamen Rider Zero-One and Zero-Two respectively.
• Big Damn Heroes: Is as Kamen Rider Zero-Two dashes between Aruto and S, right as the former is about to deliver a Hellrising Impact on the untransformed S and stopping Aruto's attack.
• Breather Episode: This film is quite a breather before all goes downhill in the Zero-One Others movies.
• Bike Fu: Valkyrie gets a scene where she takes on several enemies on a motorbike.
• Chekhov's Gun: In the opening Zero-Two is beaten and has the Driver taken away so S can use it's Zea connection to start his plan then he simply tosses it off to the side. When Aruto returns to fight him again as Zero-One the driver is very prominently shown still laying there right where S left it and goes flying when he destroys the stadium. A short while later Is finds it in the rubble and connects to Zea through it to try to find Aruto at which point it's revealed there was a backup of her in it the whole time that restores her memories and emotions and allows her to transform with it to go rescue Aruto and fight alongside him.
• Climax Boss: S is the greatest threat Aruto has to deal with, but he is not the last enemy. That honor goes to Bell, who takes S' belt and driver to carry out the plan in S' stead.
• Cruel and Unusual Death: Akane, S's wife, died during the Daybreak Town Accident when the Ark hacked the nanomachines inside of her and used them to tear her insides apart.
• Curb-Stomp Battle: Even though Bell betrays S to become Kamen Rider Lucifer, he's met with what is possibly the quickest case of The Worf Effect in the entire franchise as Aruto and Is immediately gang up on and beat the tar out of him in their final forms. Lucifer isn't even able to start up any of his finishers.
• Dark Is Not Evil:
  • Kamen Rider Eden's suit is almost entirely black, save for bits of blue and red and purple that make up the armor, and while he is willing to destroy the world in his pursuit to create a paradise, S is an Anti-Villain who is desperate to see his fiancé again.
  • Played with in regards to Hellrising Hopper. The form itself is dark and menacing, with the movie's creators stating it to be a Rider that could potentially end the world. In the hands of Aruto, however, it's a Godzilla Threshold that must be passed if he wants any chance of defeating S.
• Demoted to Extra: Ikazuchi and Naki appear but do not transform during the movie, due to the script largely having been written before the hiatus and originally intended to have been set during the series rather than after it in continuity. Ikazuchi gets it the worst because he's only in one scene, but Naki also plays a very minor supporting role throughout the film.
• Easily Forgiven: Both Horobi and Gai Amatsu don't have their atrocities from Zero-One acknowledged at all, even when they're relevant. Horobi doesn't get called out when Is shows up for murdering her original self in cold blood, even though it's acknowledged the original Is is still dead. Gai gets let off slightly less easily, given how the other Riders are shown to view him as The Friend Nobody Likes, but still no one calls him out for causing the Daybreak Town Incident, aka the event that killed S's wife and drove S to enact his Evil Plan in the film.
• Elite Four: Thinknet has four executives who act as S's lieutenants and transform into custom versions of Kamen Rider Abaddon — Moore, Buga, Lugo and Bell.
• The End of the World as We Know It: The first part of S' plans, as he intends to Restart the World. Just as he stated to As in his brief appearance in The Stinger.
• Final Boss: The last enemy Aruto and the others face is Kamen Rider Lucifer AKA Bell, who betrayed S and took the Eden Driver and Zetsumerisekey and activated the Driver's hidden function to assume his Rider form.
• Foil: Despite being described as a Rider Form capable of ending the world, Hellrising Hopper is a total contrast to Aruto's other berserker form, Ark-One. Whereas Ark-One was driven by Aruto being consumed by vengeance, Hellrising Hopper is the result of Aruto willing to risk his own life by using a power that could easily kill him and countless others if he wasn't careful. In terms of Aesthetics, Ark-One resembles Rising Hopper and is primarily colored white, while Hellrising Hopper looks more like a demonic version of Shining Assault Hopper, Aruto's Mid-Season Upgrade form and is a subverted case of Red and Black and Evil All Over. Aruto also had autonomy as Ark-One and was able to restrain himself from attacking people, only targeting the object of his fury and anyone who deliberately got in his way, while Hellrising Hopper turns Aruto into an uncontrollable berserker until his transformation is reverted.
• Godzilla Threshold: The Hellrising Hopper Progrisekey, in that whoever uses it becomes a Rider capable of ending the world. Aruto himself has to use it if he even wants so much as a chance to defeat S, who has defeated him at almost every turn.
• Grand Finale: Acts as one for Kamen Rider Zero-One, given how the main story left off on basically No Ending.
• Greater-Scope Villain: Gai Amatsu is this for the film, even though he's technically one of the protagonists, given how S's whole reason for turning evil was because he lost his wife in the Daybreak Town Accident, which Gai deliberately caused. As thinks she's this, but she's really a Big Bad Wannabe since Thinknet has no intention of actually spreading malice like she hopes.
• Karma Houdini: Gai once again gets let off with just a disapproving look from the other Riders, even though he corrupted the Ark and caused the Daybreak Town Accident wherein S's wife died an incredibly Cruel and Unusual Death, spurring S on and causing the entire plot of the film.
• The Mole: Makio Nodachi, a ZAIA Enterprise executive in league with Thinknet who supplied them with the tech they needed for their Evil Plan.
• The Movie: REAL×TIME is this, as well as the end to the main story.
• Not-So-Well-Intentioned Extremist: S, real name Rihito Isshiki, is a rare example that's still an Anti-Villain. He has a genuine desire to create a paradise, but so he can reunited with his fiancé, and plots to leave his followers behind to die in the ruins of the old world while forcing everyone else to comply with his vision of paradise.
• Pun-Based Title: S sets a one-hour countdown before the world ends. The plot of the movie is also resolved in just a little over an hour, with the timer showing up occasionally. In other words... the movie is moving in REAL×TIME.
• Satanic Archetype: The film has two.
  • S is a Dark Messiah clad in a white cape deceives people into following him and plots to bring about doomsday in order to remake the world in his image.
  • Bell has a name derived from "Belial", one of the names given to Satan himself, and usurps S late into the movie in order to take over his paradise and make it his own. Hell, his Rider form is even named Kamen Rider Lucifer. You don't get much more on the nose than that.
• Small Role, Big Impact: Downplayed with As. She supplied S with the Eden Driver, but the actual tech for Thinknet's whole plan came mainly from their mole in ZAIA Enterprise. Effectively As was just an Unwitting Pawn for S who enabled him to put up a fight for Zero-One.
• Something Only They Would Say: The 2nd Is stops Aruto from destroying himself and Eden with the Hellrising Hopper form and says he can't die before she's able to laugh from her heart at his jokes (which Is said to him right before she died) and that she won't be able to handle losing him (which Is said during the simulations to create the Zero-Two Driver where she saw him dying repeatedly) This has him realize she's regained herself and allows him to snap out of it.
• Soul Jar: In addition to hosting Zea’s interface in the absence of the original Satellite Zea, the Zero-Two Progrise Key turns out to have been one for the original Is, who meets with her Replacement Goldfish counterpart in Zea and merges with her to come Back from the Dead.
• Standard Evil Organization Squad: S, Bell, Moore, Lugo and Buga, who are the leaders of Thinknet.
• Together in Death: [[spoiler:Rihito uses his final moments to reunite with his wife in Thinknet's digital world and be with her as the servers are shut down.
• Took a Level in Badass: In the main series, Is mainly served as support and analyzed Aruto's opponents in order to figure out the best countermeasure. Not only does she take to the battlefield, she even becomes a Kamen Rider herself. As in, Kamen Rider Zero-Two.
• Trailers Always Spoil: Only partially done, as while promo pics and the trailer shows that someone else will be using Zero-Two to fight alongside Aruto it does not show that it's Is, although by process of elimination most people were able to figure it out anyway
• Unwitting Pawn: S' followers go through with his plan because they believe that they're creating a new Paradise on Earth, which is technically correct. S' true plan is to create a virtual paradise free of suffering for his fiancé and the victims of their attack, who are actually having their consciousnesses uploaded into his new world rather than being killed. He would never allow a group as malicious as Thinknet near his fiancé's new utopia and fully intends to leave them behind to die in the broken remains of the real world.
• Well-Intentioned Extremist: Bell. Unlike S, who just wanted to be reunited with his wife, or his three fellow Thinknet commanders, who use the cult's purge as an excuse to indulge their inner sadism, Bell actually does want to create a paradise, technically making him the group's Token Good Teammate. The only problem is that doing so involves a highly unethical Restart the World plan.
• The Worf Effect: Aruto uses Zero-Two his most powerful suit in the opening scene and but gets beaten pretty badly and has it taken away, forcing him to switch back to his Zero-One forms for the rest of the film. Thankfully, Is as Zero-Two is much more effective.
