Where is the Truth About the Goddess (女神の真実はどこにあるのか Megami no Shinjitsu wa dokuniaru no ka) is the forty-second episode of Kamen Rider Drive. This episode marks the debut of Medic's Over Evolved State.
Shinnosuke un-transforms and questions Medic about the reasons behind her actions. Medic, not knowing what her true love for Heart means, decided to respond. What came from her mouth was the secret of the day the Global Freeze happened a year ago, the same day the Medic that looks like Misuzu Hatori was born. Meanwhile, Banno, now having succeeded in becoming Gold Drive, targets Medic again. The Promised Number is 4 Over Evolved Roidmudes. Counting Gold Drive, who already has the power of a Over Evolved Roidmude, if Medic Super Evolves, they will be complete. Banno goes into action to trigger her evolution.
An untransformed Shinnosuke peacefully asks Medic of what happened. At first, everyone thought she is undergoing another inhumane experiment but Shinnosuke then realizes that all Medic wants is to awaken her in order to achieve Over Evolved. Back at the night of the Global Freeze, Roidmude 009 was helplessly weakened from Protodrive and his Shift Cars resistance. While withdrawing from the battlefield, she stumbled upon an injured Misuzu and synchronized to assume her appearance and at the same time gained her designated emotion: love. Using said emotion as catalyst, she healed Misuzu and later most of the injured Roidmude battalions but as a side effect, she absorbed their negative emotions, explaining the reason why she willingly cost her own kind for her own benefits. Shinnosuke decides to help her solve the case in order to bring back her former kind self, despite knowing the risk of her becoming his ultimate enemy.
Banno and Brain appear, where the evil doctor transforms into Gold Drive and challenges the Riders, Drive and Chaser. But Gold Drive easily removes Type Tridoron from Drive and finishes them with the stolen Door-Ju and Break Gunner. Gold Drive offers Medic his help as she agrees and takes the party to his lab. At the Amoroso Ballet Class, Shinnosuke learns that Misuzu is a star ballet student, the same thing said by her boyfriend Kazuya, but her instructor reveals that she had no boyfriend and Kazuya is actually her bitter rival. Kyu tells Shinnosuke that Kazuya is a laundromat manager in debt of 10 million Yen as he cheated by collecting "funds" for the ballet class since a year ago, right during Misuzu's disappearances. As Shinnosuke leaves the class, he hears a dog bark.
Before Kazuya is about to drop Misuzu from the stairs, Shinnosuke, Genpachiro and Kiriko stop him, now knowing the truth behind his deception. A year ago, Misuzu had discovered his dirty trick to pay a huge debt and tried to expose it, but he ran her over in a car during the night of the Global Freeze. After arresting Kazuya, Shinnosuke leaves for an important business. Heart approaches Brain, asking for Medic's whereabouts while she awakens in Banno's Lab, as Gold Drive had finished throwing away the impurities in her heart, now allowing her to achieve Over Evolved based on her love emotion without any resistance. Brain seeks apology for what happened and wishes to endure any punishment from Heart as the latter desires to eliminate him.
Kiriko, Go and Chase brings Misuzu to the park and finds Medic dressed in white attire, whom wants to kill them. Kamen Riders Mach and Chaser fight her but Medic feels strange that there are still no signs of evolution. While Heart watches the battle from safety, Medic's dog passes by and arrives on Misuzu, which awakens her, revealing it to be Shou. As Shinnosuke explains, Shou is Misuzu's lover, which now explains Medic's affection to it earlier. During the Global Freeze, Shou was also a victim of Kazuya's hatred to Misuzu, having injured from the same hit and run accident. When 009/Medic copied her appearance and brought her to safety, she healed the injured dog as well and finally synchronizes to the love emotion, just like her affection to Heart. Finally, she gains her Over Evolved state and defeats Deadheat Mach and Chaser.
But something goes wrong, which reverted her white dress back to black. Gold Drive reveals that he made an extra modification where her mind would be erased once her Over Evolved State achieved, causing her to become his puppet. Out of rage, Heart tries to attack Banno as the latter had Medic fight him but Shinnosuke barged in and tried to stop her. Gold Drive set her target to Kamen Riders but once she was about to kill them, the Over Evolved Heart defends them, heavily injuring him as Gold Drive brings them away, leaving Go and Shinnosuke frustated because of Banno's second time of mockery on the Riders' second failure and curses him.
As Misuzu cheerfully reunites with Shou, Shinnosuke reveals that he remembered everything they overlooked in the case, realises that all victims of the comatose cases are dog lovers, even Rinna as well whose currently played with one that Genpachiro bought. As Banno confirms himself as a member of the Promised Number, he proposes himself as their new leader and will bring forth a new Global Freeze. But Heart interferes that they lacked one, Brain, who is currently lurking into the human society to get away from them. While walking in a rainy night, he sheds a tear, asking why he felt bad for Medic.
The next day, Shinnosuke slacks from his job at a rooftop and spots Kiriko and Chase conversing. Shinnosuke wondered what they were going to talk about until he remembered that Chase had asked him what a romantic relationship was before. This leads to Shinnosuke assuming that Chase was about to confess his love for Kiriko.
