Heart was given the bad news that Chase is now "destroyed", while holding the former's Shift Speed Prototype Car in a memorial. Brain fakes his crying, stating that the tragedy wouldn't happen if his reprogramming was made in a proper way. Medic tells Heart that he was not a part of the "Promised Number", so his loss would be nothing, but Heart keeps mourning his death, so much that Brain take this opportunity to get close to Heart. Unknown to them too, Chase survived but is secretly resting at an abandoned building while Kiriko and Shift Car Mad Doctor secretly heal him.
At the Tsukushiyama shopping mall in April 2, SWAT units had safely evacuated the building with the courtyard's monument exploding, based on a bombing notice. This was the third case of serial bombings which led to the Special Investigation Unit's interference in the next day. Oddly enough, all bombing spots were marked clean by SWAT forces before the explosion happened. For now, only Kyu, Shinnosuke and Genpachiro were the available members with Jun on business, Rinna doing research and Kiriko just arriving after she "overslept".
Suddenly, a new bombing notice was sent, which stated a bomb would explode at the Kuruma Leisure Amusement Park. After the evacuation of the amusement park, Drive and Mach searched for the bombs until Drive spotted a suspicious man recording the Ferris Wheel with his smartphone. The man ran away after being caught by Shinnosuke. As the time strikes, Mach mysteriously blew up and fell from the Ferris Wheel. It turned out to be Shoot Roidmude, wondering why the Ferris Wheel didn't explode. As Drive battled Shoot, he mysteriously attacked for unknown reasons. Shoot escaped, while leaving a purple dart which falls from Mach's Tomarle shield. At the Drive Pit, Mr. Belt noticed that Mad Doctor disappeared. As Go leaves, Shinnosuke wondered why the Ferris Wheel didn't explode along with Go. Reminded of Scooper Roidmude's photographic manipulation technique, he suddenly thinks of the suspect earlier.
Takuro Mogi, the suspect, was interrogated for the bombings as he appeared past bombing places like Midorigaya East High School (his school), the train station and the Tsukushiyama shopping mall. He said that he wanted to witness the bombings while claiming that recording the Ferris Wheel was a mere coincidence. A reported from Metropolitan Police Department reached Genpachiro, revealing that four separate places (Industrial Building 6, City Cultural Hall, Midorigaya Park and Tsukushiyama Aquarium will be bombed at 3 PM. Takuro wanted to watch the bombings but preferred to stay to prove his innocence. As he commented if he would capture the scenes with light speed, Shinnosuke thought of something and entered Top Gear again. He called Go, whom was in the middle of training.
Shoot Roidmude stands on the top of a building and was about to make some explosions before Shinnosuke and Go appeared. Shinnosuke revealed that his ability was to fire missiles and darts at a great speed so much that it cannot be detected by the naked eye. Deadheat Mach fought Shoot while Drive Type Formula stopped the warheads. Just as he chased the fourth warhead, his body suddenly fell from mechanical shock, with the Pit Crew Shift Cars fixing him and Drive assumes Type Formula Mantarn to boost his speed and stopped the final warhead.
Followed by his Berserk Mode state, Deadheat Mach was defeated by Shoot, causing his belt to be damaged which cancels his transformation. Drive made it just in time, using Jacky and Sparner to outmatch Shoot before destroying him with Trailer Impact. Takuro was finally released after no evidence found on his relation with the Roidmude. While Kiriko made her visit to Chase, he awakened and pull her, asking if she was the one who rescued him.

- Can't Catch Up: Gou, since Drive's recent power-up.
- Cut-and-Paste Note: The bomber threat's are delivered in such manner.
- Green-Eyed Monster: Due to Rinna and Harvey's development focusing solely on Type Formula. Gou even goes as far as asking "you only need Drive, right?" - which he later dismisses as a joke.
- Hidden Depths: Besides the envy over Drive, Gou seems to be under some other pressure, due to the Roidmudes and time.
- No-Holds-Barred Beatdown: When Gou is immobilized due to Deadheat's time limit running out, Shoot lays on him hard. It results in Mach's Driver being destroyed.

- Speed Stripes: They appear when Shinnosuke races to catch the missiles.
- The Roidmude Count: 68The Answer: Kamen Rider Drive Type Formula...to the chagrin of Kamen Rider Mach.
