Aruto and Izu arrive in Hiden Intelligence HQ. Izu introduces herself as Aruto's HumaGear assistant and guides him to the building. Inside, Aruto is halted by a security Humagear. Upon discovering that Aruto is the new CEO, the security backs down.
Meanwhile at Daybreak Town, Horobi claims that they're nearing a singularity and commands Jin to wreak havoc again with Zetsumerise Keys. Jin departs and forcibly transform a delivery service HumaGear into Kuehne Magia to attack Hiden Intelligence HQ.
Izu takes Aruto to the CEO's office, his first task as the new CEO is to welcome the representatives of A.I.M.S, a government special force for A.I.s. They are Yua Yaiba, head of R&D and Isamu Fuwa, the force's captain. Isamu directly accuse Hiden Intelligence at covering HumaGears rampage at the amusement park, but Aruto with the help of Izu easily denies all accusation. To break the ice, Aruto tries to do his signature jokes, but as usual it's so lame and no one is reacting, beside Isamu that is apparently shaking with anger. Their conversation is cut short when an intruder is detected inside the HQ.
It turns out that Kuehne Magia enters the building and is wrecking havoc inside. As A.I.M.S personnel are engaging it, the security HumaGear protects civilians inside. Isamu tries to transform using Shooting Wolf Progrise Key but he cannot as Yua doesn't authorize it. Isamu then battles Kuehne Magia using only his ShotRiser. Izu tells Aruto to transform and he does so, and Zero-One enters the fray. But, Kuehne Magia escape using its wings... causing A.I.M.S to target Zero-One as they think he's a HumaGear too. Zero-One nimbly escapes and transforms back to Aruto, and then tricks both Isamu and Yua.
Still, Isamu takes Aruto away. He explains his hatred for HumaGear, because as a kid, he experienced the terror of HumaGears in an incident that decimated Daybreak Town. The same incident when Aruto's father figure HumaGear, Soreo Hiden, destroyed after protecting him from an explosion. After Isamu departs, Aruto comes back to the HQ to search for security HumaGear that protects the civilians before. Upon learning his name as Mamoru, Aruto tells him to search for maintenance as his body is wrecked by Kuehne Magia. But unbeknownst to them, Jin watches the exchange and then corrupts Mamoru.
Later, Jun Fukuzoe as the vice president of Hiden Intelligence held a press hearing about the incident before. He denies that the culprit is a HumaGear from Hiden, but then Kuehne Magia reappears to attack again. Now ready, A.I.M.S personnel, led by Yua, force the Magia outside the building. Meanwhile, Jin arrives with Mamoru in tow. Jin introduces himself as a member of Metsubojinrai.NET and commands Mamoru to kill Aruto, transforming him to Ekal Magia. Izu explains that a corrupted HumaGear cannot be restored to normal, thus Aruto must destroy Mamoru.
A.I.M.S successfully lure Kuehne Magia into an empty dock. But the Magia is too hard for normal bullets, until Isamu arrives with ShotRiser and a belt buckle. Isamu forcibly opens the lock of Shooting Wolf Progrise Key and transforms to Kamen Rider Vulcan for the first time.
Back in Hiden Intelligence HQ, Aruto finally transforms into Zero-One and he begins to fight Ekal Magia. Zero-One overwhelms the Magia, until he decides to escape using a hacked motorcycle. Izu tells Aruto about the RisePhone's ability to summon the Rise Hopper bike, and Zero-One go after the Magia outside. He successfully thrown Ekal Magia from the bike, and they continue the fight in an empty dock.
Vulcan easily handles Kuehne Magia as Yua records his fight. He uses Shooting Blast to destroy the Magia while Zero-One defeats Ekal Magia using Rising Kaban Strash. As the two riders gaze at each other in curiosity, Zero-One vanishes.
The next day, the press are rushing at Jun Fukuzoe for the two incidents involving HumaGears the day before. Both Isamu and Yua are also there too. Aruto then comes in and introduces himself as the new CEO of Hiden Intelligence. He plays the recording from Izu about Jin and Metsubojinrai.NET, letting the press know about that terrorist organization. He claims that HumaGears are developed by Hiden Intelligence to realize humanity's dream while looking at new security HumaGear, designed to resemble the destroyed Mamoru. Then, a journalist asked about Aruto's past job as a comedian and he performs his joke, destroying the serious mood. Isamu is seen shaking again... because he's trying hard not to laugh at Aruto's lame joke.
- Actually Pretty Funny: Surprisingly, the straight-laced Isamu actually found Aruto's joke funny.
- Death of Personality: This episode reveals that once a HumaGear's programming has been rewritten by MetsubouJinrai.NET, it is virtually unrecoverable and must be destroyed.
- Determinator: Isamu is so determined to wipe out the Magias that he opens his Transformation Trinket by force without Yua's unlocking authorization.
- He Went That Way: Aruto dupes Isamu and Yua into thinking Zero-One, who they think is another rogue HumaGear, fled in the opposite direction after they find him post detransformation.
- Injured Limb Episode: The amount of power Isamu used to force his Transformation Trinket open breaks his arm, with it in a sling at the end of the episode.
- Nice Job Fixing It, Villain: Due to Jin introducing himself in front of Aruto, he now has proof that MetsubouJinrai.NET is the group responsible for both the rogue HumaGears and Magia and can make their existence public.
- Obstructive Bureaucrat: Jun Fukuzoe, the Vice-President of Hiden Intelligence, was the one responsible for trying to cover up the rogue HumaGear attacks, as he believed it would hurt the company. Aruto more or less shoves him aside and upstages him by showing off his PR skills and reveal the existence of MetsubouJinrai.NET — the group responsible for the androids being hacked.
- Once More, with Clarity: The first time we see Isamu react to Aruto's jokes his fist is trembling as if he's fighting to hold back the urge to deck him. When Aruto pulls the same joke at a press conference Isamu is there for we see his fist trembling again, only for the camera to pan up to reveal he's fighting back laughter because he actually thinks Aruto's lame jokes are hilarious.
- Smoke Out: Vulcan saw Zero One through the hole he shot...only for him to disappear in the smoke.
- Three Laws-Compliant: When Aruto asks Izu about A.I.M.S' rights to prosecute AI-based violations, Izu explains the First Law, namely a HumaGear must not injure a human being.
- You Remind Me of X: Aruto gives a scarf to Mamoru since he reminded him of his HumaGear father, protecting people. After Mamoru is hacked and Aruto is forced to put him down, he orders a new Mamoru be built, complete with the scarf he was given.
