About
Granutes are monsters that use humans as ingredients to create snacks known as 'Dark Treats.' To stop this, Shouma Inoue—a lower-class Granute boy born to a Granute father and a human mother—uses the 'Gavv Driver,' a mouth-shaped transformation belt. By inserting Gochizo into the belt, he transforms into Kamen Rider Gavv and fights the Granutes to save humanity. What are Granutes and Gavv? A Gavv is a mouth located on the abdomen of the monster species known as Granutes. By consuming Dark Treats, which allow them to take human form, they can disguise themselves. They use their tongues to bind humans into 'Acrylic' forms to be used as ingredients for Dark Treats. Granutes typically possess animal-like features. What is the Gavv Driver? It is a non-removable biological transformation belt. It is red and shaped like a mouth. To transform, the user opens the mouth, inserts a Gochizo, closes the mouth, turns the lever, and presses the button on the side of the belt (Exclusive to Shouma). What is the Blastum Gear? It is a removable transformation belt. By inserting a pudding-type Gochizo into the Blastum Gear and lowering the lever, one transforms into Kamen Rider Vram. Valenbuster A gun-type transformation device. By raising the lever to open it, inserting a Gochizo, raising and lowering the lever three times in succession, and pulling the trigger, one can transform into Kamen Rider Valen (Exclusive to Hanto). Stomach Corp. An evil corporation that produces Dark Treats. The organization is composed entirely of Granutes, and they dispatch Granutes to the human world to harvest ingredients (humans).
