Jun Fukuyama
The character was created by Clamp to fill their need for a main character who would observe Yūko's work and learn from her supernatural activities. Jun Fukuyama voiced the character in Japanese, and Todd Haberkorn did so in English. To indicate Watanuki's growth, the anime staff asked Fukuyama in later animated works as well as the film. Shōta Sometani portrays the character in the television drama.
