Roidmdue 066 tries to run away from several Special Forces Troops and traps them in a Heavy Acceleration but one single trooper counters it with Pikopiko 3 and kills him with an Anti-Roidmude bullet.
At the Special Defense Operation Center, Akio Togama of National Bureau of Defense congratulates Jun Honganji and Rinna Sawagami for their help in supporting his troops with similar gadget to Drive, as 066 had been killed and requesting Rinna to reduce the size of Pikopiko 3. Ever since Soichi Makage had been exposed as a mole and terminated, the police forces is currently strengthening their defenses. Akio gives Honganji and the Special Investigation Unit a case they need to solve. Using the remains from 066, the Unit theorizes that the Roidmudes tried to recreate Global Freeze, as 22 Roidmudes now still at large. Meanwhile in the cafeteria, Chase asks Shinnosuke if he loves Kiriko, as the former spied him trying to tell something to Kiriko but stops when witnessing an eavesdropping Shinnosuke. He denies, telling Chase the type of woman Kiriko is and she appears behind them and calls Shinnosuke for a new case. But he thinks this in his mind, asking himself if he is really falls for Kiriko.
At an abandoned factory, Heart laments for 066's death now with the Roidmudes left is 22. Roidmude 013 of the Reaper Legion reports to Gold Drive of Brain's discovery but beaten for being late until Heart protects him, having experience the same kind of torture from Banno. Brain works as a delivery truck driver and happily laughs in his camouflage, until Medic and three Reapers ambushed his truck. Under Kyu's reports of Brain's sightings, the three Kamen Riders rush to the scene and kills the Reapers, with Medic flee from the scene, as well as Brain.
The team now learns of Banno as the Roidmude's leader, the Promised Number consist of four and the spot for the next Global Freeze. The first Global Freeze only covers 1/4 of the world and thus if all four Core Driviars of the Promised Numbers reacted, a new Global Freeze can be created. The team departs but Rinna tells them that they were forced to hold off the transformation for a moment, as she is currently data coating the Shift Cars, Signal Bikes and Trailer-Hou to prevent Gold Drive from stealing them.
Upset that Brain gets away again, Gold Drive calls forth Roidmude 004, as Heart trembles in shock after learning the supposedly lost battalion was an underling of Banno and witness his human form. While waiting for the data coating at the cafeteria, Chase asks Go if he knows Kiriko's lover, causing the latter to surprise and reminds him that he is a Roidmude and assures that his sister will never falls for him and even rejects his friendship. Mr. Belt even surprises when Shinnosuke asks him for advises in romantic relationship in the middle of their routine patrolling, as he is a scientist and currently no longer a human. After a long chat, Mr. Belt regains confidence, advising Shinnosuke not to act cool towards Kiriko. Kiriko reports to them that they have detected Brain.
Wanting to help Medic, Brain invades the Central Intelligence Agency and knocks down the workers. While trying to find a way to save Medic, he stumbles upon an article of Mitsuharu Kineta the human template he copied and now knows the reason behind his obsession to wear glasses and fond his napkin. He even remembers his past: long ago in the Global Freeze, after being weakened by Protodrive for trying to protect Roidmude 010 he invaded the tower and copied the man's memories, later using their supercomputer to broadcast his warning of the Kamen Rider. While now knowing that he has been living as a copy of this man in his entire life, "Krim Steinbelt" and Gold Drive appears, surprises him and tries to get away from them until Booster Tridoron saves him.
Exiting from the vehicle, Shinnosuke witnesses Roidmude 004 and recognizing him for abducting Mr. Belt sometime ago, even shocks to see him taking the form of Krim Steibelt, much to the original's dismay, since Banno had also stole his intellect. Long ago, 004 copies Krim during the trio Roidmudes' assault on his home, but because of the state Krim was in, Krin's data on 004 was erased sometime later, followed by his deactivation after Global Freeze until Banno reawakened him and Krim's data.
Shinnosuke fights while ordering Brain to escape, as he temporarily sees the latter in distress. While Rinna's coating allows Drive Type Tridoron to retain his Shift Cars, but his main weapons are exceptions. Soon, he uses trailer-Hou and tried to finish the two, but Heart steps in and absorb the attack. He believes that Banno can revert Medic back to normal and orders Drive not to show off any senses of sympathy, while releasing the excess energy from the Trailer Big Impact into a destructive wave before the party flees. The wave endangers Kiriko and Drive rushes to her aid.
- Applied Phlebotinum: The Special Response Unit of the police use specialized ammunition to take down 066.
- Big Good: Makage/001’s successor as Secretary Of Defense is shaping up to be this, as he is quite supportive of the SCU and points out where they'd do the most good.
- Combat and Support: 004 and Gold Drive make a formidable team, especially once Gold Drive hijacks the Door Gun and Handle Sword. He engages Drive at close quarters with the Handle Sword while 004 backs him up with the Door Gun.
- Lost in Transmission: During the Global Freeze, a heavily wounded 003 broke into a communications array and sent a message to his fellow Roidmudes worldwide to “beware the Rider in the Mask! Beware… the Kamen Rider!”
- Incoming Ham: When Brain comes to the horrified realization that he's nothing more than a copy of a real person (due to adopting his human template’s tic of having a handkerchief with him at all times), 004 interrupts him with a gloriously hammy, “Yesssss…”
- Killed Offscreen
- While 066 was shown to be shot down by the police, his core wasn’t blowing up in the process.
- At the time of airing, Roidmudes 012, 051, 055, 077, 099 and 100 had not appeared yet but were listed as destroyed. However, it turned out they were being reserved for future projects, a flashback in the final episode and other DVDs set before this episode: 012 and 055 appeared in the final episode's flashback; 051, 077, and 099 are in Kamen Rider Chaser; and 100 in Type LUPIN.
- She Is Not My Girlfriend: Shinnosuke insists that he has no romantic feelings for Kiriko when Chase presses him on the issue. He is forced to admit to himself that he does have feelings for her, and has had said feelings for a long time now.
- Spit Take: Both Shinnosuke and Gou responds like this when Chase tries to discuss Kiriko. Specifically, he asks if Shinnosuke is in love with her and asks Gou whether Kiriko favors Shinnosuke or Chase himself.
- Took a Level in Badass: The regular police force are finally able to battle against the Roidmudes, though the acting-Secretary of Defense is quick to point out his suspicions that their weapons are only effective against unevolved Roidmudes.
- 13 Is Unlucky: It sucks being 013. If becoming a Reaper Legion member isn’t enough, they received mistreatment from Banno for not updating Brain’s whereabouts sooner. And then 013 did not last for the entire episode, being destroyed by Kamen Rider Drive as they accompanied Medic trying to abduct Brain.
- The Roidmude Count: 19The Answer: Once the Promised Number is gathered at the Promised Land.
