The six heroines from One have appeared in the Eternal Fighter Zero dōjin games by Twilight Frontier. Additionally, Rumi Nanase can be seen as a background character in several episodes of the Kanon anime series by Kyoto Animation. Itaru Hinoue, the art director of One, included illustrations from One in her art book White Clover: Itaru Hinoue Art Works released in 2009. A sequel loosely based on the One visual novel titled was produced by the visual novel studio BaseSon, another brand under Nexton. One 2 was released first on April 26, 2002, and then again on April 25, 2003 with added voice acting, scenario, CGs and music. One 2 used the concept of the Eternal World established in One as a major motif as One had done. The Eternal World in One 2 is better explained than in One, though the two versions of the world differ to a certain extent due to the scenario writers that worked on One not being credited on the production staff of One 2''.
