Shoma Inoue. A young man who can transform into Kamen Rider Gavv. A friendly-looking young man. Height: 178cm. 22 years old. 【Secret】 A half-Granute, half-human. By eating sweets like gummies, he has the ability to produce Gochizo from the Gavv (belt) on his abdomen. He dreams of making "Light Sweets" that both Granutes and humans can eat to become happy, aiming to become a "Happy Confectioner." He came to 'Oishii-na Town' to research sweets making. Perhaps because he is half-Granute, even after falling into the sea or being thrown from a plane in the sky, he remains uninjured and complains of hunger instead. He possesses the vitality to survive such events, the sturdiness to wreck a truck he collided with, and the reflexes to catch drivers thrown through windshields with both hands. He has the running speed to reach distant places in an instant and the arm strength to easily carry heavy objects that would take several humans. By eating sweets, minor skin wounds heal instantly, and he can recover from serious injuries overnight. He possesses superhuman physical abilities. 【Gavv】 The name of the second mouth located on the abdomen of the Granute race. By chewing the generated Gochizo through this Gavv and "smacking his lips" (in a physical sense), he manifests the characteristics of the Gochizo to transform or generate tools.

He is currently traveling with a cracked Taka Medal in hand. "I can do it! As long as I have a little bit of money and tomorrow's underwear."
