Comment: I was happy to be offered to work in the Pokémon movie again this year. In the past few years, I've alternated between playing a human and a Pokémon, but I'm reassured by the fact that my character, Professor Zed, has Karen, played by Ms. Nakagawa, as his assistant. I saw the trailer for the film, and from the footage I saw, I was excited to see that director Yajima is going to bring a new style to the film again. I want to be one of the first to see the movie!
