Brain had just finished making adjustments to Shoot Roidmude's body, and ensured that the Roidmude would help him win Heart. Kiriko was asked by Chase if she was the one whom saved him, as she confirms. Chase felt guilt of her kindness, even after he had nearly killed her multiple times.
Exactly two days after his interrogation from the police officers, Takuro walked out from his school and met Shinnosuke again, as he noticed Takuro's change of behaviour compared to the last time they met. The boy becomes more serious and ordered Shinnosuke to get away from him. Rinna had just finished repairing the Mach Driver Honoh, but Go desperately wanted a new upgrade after his previous defeat from Shoot.
While on the sidewalk, Takuro received a message, stating that a bus stop near him would exploded at 1.13 pm and it exploded a minute later. Takuro ran away from the scene, only to bump into Shoot Roidmude. Shoot declared that his role in sending bomb threats is over, and now he's targeting him. Takuro tried to run away from him but he received a new message that the bicycle parking lot he stand in would explode in 1.44 pm. Fortunately, Shinnosuke saved him from the explosion. Mach arrived and battled Shoot but quickly incapacitated by his neurotoxins until Kiriko saved him with Mad Doctor.
At the Unit's office, Takuro revealed that it originally started as a prank. After going through his mundane life for days, he came across a bombing case. Shoot appeared to him while he's alone, and struck a deal for Takuro to send bomb threats and him bombed said locations. However, after his first destruction, he instead had decided to eliminate Takuro. Mr. Belt and Kiriko discovered that ever since Mashin Chaser upgraded himself, Drive would do the same to counter him but in the end, that makes Go leaving behind despite Mach's system supposedly made even more advanced than Drive System.
While Jun had cuffed himself to Takuro, Kyu just received a new bombing threat on Takuro's phone that stated to eliminate him. Shinnosuke went out, followed by Otta (whom stated to "evacuate nearby citizens") and Kyu (since he's "not" a police officer), leaving Jun trapped with Takuro. Kiriko comforted Go and reminded him that he is always confident ever since their childhood, as well as him becoming what remained for her after they were orphaned. With one minute left, Drive and Mach transform where Mach incapacitate his missiles at first before attacking Shoot. However, once fallen into his toxin's effect, Mach forced himself into Berserk Mode, saving him at the same time mastering the Dead Zone's side effects. Drive Type Formula joined the battle and they destroy Shoot with Trailer Impact and Heat Kick Macher.
Takuro was freed once again, with Jun giving him several words of encouragement before he left. Go decided to call off his upgrade, having already strong on himself. Meanwhile, Chase left his hideout and decided to walk on his own while bringing along some of Kiriko's flowers.
- Ain't Too Proud to Beg: Gou gets on his knees and begs Rinna and Mr. Belt for a new upgrade.
- Chained Heat: The Chief handcuffed Mogi, arresting him for the bombings. Moments later, Shoot sends an email saying that he going to make Mogi go boom. And the keys to the handcuffs got lost somewhere. Whoops.
- Exactly What I Aimed At: After facing Shoot and evading his darts for the second time, even grabbing some in the air, Mach gloats that the same trick won't work this time. Unfortunately for the white Rider, the Roidmude got upgraded with Brain's poison, with he was able to infect Gou with through the darts he caught.
- Fire-Forged Friends: The Chief and Mogi bond over the prospect of being blown up by Shoot.
- Foreshadowing: The Chief tells Shinnosuke to cover him for the new First Investigation Division head... who makes his appearance next episode and we see why the Chief is wary of him.
- I Just Want to Be Special: Mogi's motive for starting sending the bomb threats. It wasn't meant to be anything but a joke... but then a Roidmude got involved.
- Internal Homage: The main plot of episode focuses on Gou trying to become stronger. Which is fitting, as it aired on the 40th anniversary of the premiere of Kamen Rider Stronger.
- Misguided Missile: Drive Type Formula uses its speed to guide Shoot's missiles back at him.
- Mood Whiplash: In-universe example. After meeting Mogi at his school, Shinnosuke notes that he looks much less energetic and exited than when he was interrogated last episode.
- Separate Scene Storytelling: We got two instances of this:
- Mogi testifies how he became involved with Shoot Roidmude to the Special Unit.
- Kiriko reminisces to Gou on their childhood, when he got beaten for the first time in karate class.
- You Are Better Than You Think You Are: Mr. Belt gives Gou a pep talk to this effect when Gou is despairing how, despite Mach supposedly being the superior system, it's Drive who gets more upgrades and is growing ever stronger. It's here we learn that, much like Drive, Mach's power comes from its user's state of mind.
- The Roidmude Count: 67The Answer: His confidence in his own strength.
