Nakasumi and Ms. Kyoko

Voiced by:  Clyde Kusatsu (Nakasumi) and Lauren Tom (Miss Kyoko)

Nakasumi was the top toy developer in the world. He was the victim of theft by Drakken and Shego in Crush. Fortunately, Kim recovered what was stolen, and in return, Nakasumi gave her a ride in A Very Possible Christmas. Nakasumi made another appearance in So the Drama, as a major part of the plot. At first, it seemed that Nakasumi couldn't speak, but understood, English. To avoid using Japanese, the series crew had Nakasumi whisper to Miss Kyoko and she'd translate. In So the Drama, it was revealed that he could speak English, and just liked whispering to Kyoko. One of Nakasumi's characters, Z-Boy, made several cameos as toys and posters. So far, Nakasumi and Miss Kyoko have appeared once in each of the three previous seasons.

In "Crush", Nakasumi's translator introduced herself as Yoshiko, while in "So the Drama", he addressed her as Miss Kyoko. It's unknown which of these is her real first and last name, though some have come to call her Miss Kyoko Yoshiko. (As Nakasumi is revealing his whispering to her is not due to translation difficulties and he is asserting a professional air to avoid bad connotations to the practice, it is more likely that he referred to her as Miss Kyoko the way any CEO might refer to his executive officer professionally; "...and this is Miss Jones." Yoshiko, on the other hand, would have reinforced the doesn't-speak-English facade Nakasumi maintained in "Crush" by using her first name when introducing herself. Thus, Miss Yoshiko Kyoko, or Kyoko Yoshiko in the Japanese tradition of placing the family name first.)
