Naoko Watanabe

Naoko Watanabe is a preteen with the gift (or curse!) of transforming into Gauko, a fire-breathing dinosaur girl when she gets too angry.
She has bottom curly brown hair and black eyes. She dresses in a plain yellow dress top with a white collar and a pink skirt.

Naoko is normally a kind and bubbly girl, however, when she becomes angry she transforms into Gauko.
