Shu Takumi (巧 舟 Takumi Shū) (born May 2, 1971) is a Japanese video game developer working at Capcom who is the main developer of the core Ace Attorney series, serving as director and scriptwriter for each game. In addition, he provided the Japanese voice for Phoenix Wright throughout the series and composed the song "Guitar's Serenade," for the video game Apollo Justice: Ace Attorney.
Shu Takumi joined Capcom in 1994 along with Hideki Kamiya. His first game was Gakkou no Kowai Uwasa: Hanako-san ga Kita!! (学校のコワイうわさ 花子さんがきた!!), a 1995 video game adaptation of an anime of the same name. He was designated as a planner, and because the director was busy with multiple projects, Takumi had some freedom in his role. In the years that followed, Takumi came up with an idea for a detective game, though nothing came out of it at first.
Takumi was later picked up by Shinji Mikami to work on Dino Crisis. However, in early 1997, the Dino Crisis team was temporarily redirected to help work on the ill-fated original version of Resident Evil 2. Takumi was then made director of the Dino Crisis project before being demoted to planner, being responsible for the first half of the game. He was then made director of Dino Crisis 2, and was able to maintain his position throughout the game's development.
