Shoma gets candy from children dressed in Halloween costumes. He is thrilled to taste the first candy that does not melt immediately, and new Gochizo are born one after another.

Meanwhile, Hanto approaches Kirari and her friends, who gossip about monsters. He goes to Kirari's dance school to look for clues. Then he sees a suspicious man following Kirari's friend Rika...!

Hanto comes to "Hapipare" to ask for help in finding a missing cake store. Shoma hears about it and secretly sends the Gochizo to search for it.

The Gochizo's report reveals that the owner of the suspicious cake store is at the kindergarten. Shoma and Hanto sneak into the kindergarten and find that the owner is actually a Granute! Hanto escapes Shoma, transforms into Valen, and angrily attacks the Granute.

Gavv joins him, and the two join forces to confront the Granute...!

Shoma, searching for a missing high school student, discovers that other "kind and gentle" people have been disappearing one after another. Are such people the only ones being targeted by the Granute? If so, Sachika is in danger! Shoma rushes to Sachika's side, but...

Shoma and Hanto finally find the Granute and transform into Riders. Then a man in a hat appears. In front of Gavv and Valen, the man changes into Lage Nine and puts on a belt...!?

Shoma and Hanto are troubled by the appearance of Kamen Rider Vram. While discussing countermeasures, Shoma is pressed by Hanto, who says, "There's something you're not telling me..."!

Shoma and Hanto confront Granute Chooul, but then Lage Nine appears. Shoma and Hanto transform into Gavv and Valen to save those who were turned into human presses! They challenge Vram and Chooul to a battle.

However, Chooul escapes with the human press in his hands. Valen has Gavv track down Chooul and challenges Vram by himself!
