He is the personal driver for Tadano.
Kobayashi is based on a Schnauzer dog. He has orange fur, white eyebrows, and a white muzzle.
He is always seen wearing a black suit with a white dress shirt, white gloves, a navy blue tie, and matching sunglasses.
Kobayashi seems fine acting as driver decoy, while ENI-O is the one actually driving the car. He likes to spend his decoy time by playing video games on his handheld console.
