One night, popular model Lira Nanao was walking on a street when a mysterious person contacted her, claims to be her biggest fan. The caller released Heavy Acceleration waves and a hooded Roidmude appears in front of her. At the same time, Chase approaches Kiriko with Shinnosuke and Go sensing her in danger as the latter rushing to her. With memories of Kiriko appearing in Chase's mind, he demanded her answers as to why but Go arrived and stopped Chase, who then left the scene.
Lira visited the Special Investigation Unit with her manager and reported the event that happened last night. Worried of her safety from the stalker/Roidmude, she asked for their help which the team happily obliged. With another rogue Roidmude reported, Brain sent Chase to deal after him. Chase agreed while struggling with several memories from the Global Freeze. Medic warned Brain that Chase would regain his past memories anytime, which Brain assured to keep an eye on. While Lira was filming a commercial at her studio, Go reveals to the Unit another suspicious stalker, Tadashi Sunahara, which might been the key to solving the case. Shinnosuke and Go then spot a man wearing a fedora secretly stalking on them and chased after him while Genpachiro and Kiriko found Tadashi and arrested him under suspicion of being a Roidmude.
As the stalker hides from Go and Shinnosuke, a Heavy Acceleration wave was released, slowing everyone but the Riders. At that time, a cloaked Roidmude appears and poisons Tadashi with his talons before getting away. Shinnosuke checked on Tadashi and spotted a tarot card beside him marked "The Fool". Go pursued the cloaked Roidmude as Mach, changing into Mach Kaksarn but lost him while finishing his roll call.
To ensure her safety, Lira was given a day off by her manager. At the Special Investigation Unit's base, Kyu gained the suspect's information: the stalker is Koichi Sakaki, a former make-up artist who began stalking women after losing his job. Genpachiro and Shinnosuke found Koichi, who was jailed after he was caught stalking again. Shinnosuke however suspected that Koichi had purposely lured them here to give him a Bat-Class Roidmude, some time to search for her, to which Koichi confirmed to be correct. Furious, they rushed out quickly to find Lira. Koichi's Roidmude counterpart pursued Lira at her apartment, revealing his true form as Roidmude 069. Go and Kiriko arrived at the apartment, but before they could take any action, the previous cloaked Roidmude, Roidmude 096, protected her from the maniac. It was revealed that Roidmude 096 was trying to protect her last night from 069. Lira quickly realised something about him but he retreated after Kiriko and the Shift Cars attacked him. Shinnosuke joined the fray and transformed into battle. Drive used Type Technic Winter and froze 069. But before they could finished 069 off, Chase appeared and fought them while struggling with Mr. Belt's voice in his memories.
Brain arrived and unfroze 069 to evolve him into a Giant Bat Roidmude. 069 flew away and took Kiriko hostage. While Drive Type Wild Wrecker hooked himself on the monster, Mach and Chaser mounted their bikes and chased him. A combination system was activated, ejecting Chase from his bike, which combined with Mach's to form the Ride Crosser. Mach drove the Ride Crosser and attacked the Roidmude, saving Drive and Kiriko. He finally finished the Roidmude and his Core in an aerial combat. As Ride Crosser spilts back into the two bikes, Chase wonders how it was able to link with Ride Macher. Brain appeared and revealed the truth: Chase was Proto-Zero, the Roidmude that aided the humans during the Global Freeze, and was also what the villain Roidmudes named the "Kamen Rider": Protodrive. Kiriko and Chase receive this news with shock.
- Catch a Falling Star: Drive manages to catch Kiriko after 069's Giant Bat form was destroyed. Since both of them were falling at the time, this does serve to answer some problems with the trope.
- Catchphrase Interruptus: Mach attempts to do his overly long introduction when facing 093, but gets shot before he can finish. He later manages to do it uninterrupted... only for the Roidmude to escape in the middle of it.
- Defensive Feint Trap: Sakaki let himself be caught by the police, so that to throw them off the case and that 069 could go unrestrained to kidnap Lira.
- Harmless Freezing: The result of Drive using Road Winter's Full Throttle on 069. He would have'd followed with the next step, if it weren't for outside interference.
- I Need No Ladders: When Lira is attacked by 069 near her room on the third floor, Mach quickly jumps to her rescue.
- Locked Out of the Loop: Both Kiriko and Chase are kept in the dark about the latter's true identity.
- Mistaken for an Imposter: When Sakaki, Lira's stalker, is arrested, Otta calls him out on being a Roidmude. It turns out the stalker was working with the Roidmude by copying his form.
- Mistaken Identity: Related to this, the cloaked Roidmude that Mach fights is not actually the Roidmude stalking Lira. In fact, the cloaked Roidmude tries to protect her!
- The Reveal: Chase was Proto-Drive.
- Suspiciously Specific Denial: After the fiasco resulting from the aforementioned Catchphrase Interruptus scene, we have this piece of dialog:Shinnosuke: Gou, where did the Roidmude go?Shinnosuke: Ah?Gou: But he managed to escape.
- Stalker with a Crush: Lira has no less than three of them!
- The Roidmude Count: 86The Answer: It was Roidmude 069.
