Taito has never explicitly credited a composer for Raimais on an album release. While Masahiko Takaki commented on the music from Raimais in the booklet of G.S.M. TAITO 5, Katsuhisa Ishikawa said on Twitter that Takaki was not the composer, but that believes he Takaki directed the music of an outsourced composer. In a later tweet, he suggested the music was by Shizuo Aizawa.
