Kazuko Tadashita was an animator working on the Sailor V anime. She was Hiromi Matsuno's friend, and the two of them had bought a set of special pencils before they started working together, with the promise that they would not use them until they had become real pros. After the Sailor Senshi saved Hiromi from Castor and Pollux, the two girls confessed that they had both already used up their pencils, as they were each worried that the other would leave her behind.
