Chiwa Saito (斎藤 千和, Saitō Chiwa) is a Japanese voice actress employed by I'm Enterprise. Saitō is one half of the voice acting duo "coopee", along with Natsuko Kuwatani. In the "Divine Design" arc of the Getbackers drama CDs, she voices a character who battles the character voiced by Kuwatani. She is a member of the voice acting group "MORE PEACH SUMMER SNOW", alongside Haruna Ikezawa, Mamiko Noto and Ryo Hirohashi. The group began as "MORE PEACH SUMMER", with Ikezawa, Saitō and Noto; all four voiced characters in the Keroro Gunso anime. The quartet's name is based on the names of their respective Sgt. Frog characters: Angol Mois (Noto), Momoka Nishizawa (Ikezawa), Natsumi Hinata (Saitō), and Koyuki Azumaya (Hirohashi).

The story starts out with the Battle of the Supernatural Powers, a tournament to decide which Celestial (heavenly being in the original Japanese version) will be the next King of the Celestial World (God in the Japanese version). Each of the 100 King Candidates (God Candidates in the Japanese version) is required to choose a junior high school student to act as their power user. The student is given a unique power and told to eliminate as many enemies as possible. The winning King Candidate will become the new King of the Celestial World and the winning student will receive the Blank Talent (Black Zai in the Japanese version), a talent that can be anything they choose. While this leads many students to thoughts of greed and selfishness, Kosuke Ueki decides to take it upon himself to win this tournament to keep that power away from those that would abuse such a gift.
