Yūto Tonokawa(都乃河 勇人Tonokawa Yūto, born January 25) (pseudonym) is a Japanese scenario writer originally from Saitama, Japan working for the visual novel developing company Key under Visual Art's. He began working with Key on their sixth game Little Busters! and wrote the scenarios for two of the main heroines: Komari Kamikita, and Yuiko Kurugaya. Tonokawa also wrote the scenario for Sasami Sasasegawa in Little Busters! Ecstasy. He provided the lyrics to one of the ending themes from the same game, "Alicemagic", as his first job as a lyricist. Due to Jun Maeda stepping down as the main scenario writer for Key, Tonokawa will take Maeda's place as the main scenario writer starting with Key's ninth title Rewrite. Among Key's staff, Tonokawa updates the company's official blog the most often.
