電撃コミックス
A manga adaptation of "Eternal Sonata" was drawn by Mimei Kuroi and published by ASCII Media Works under their Dengeki Comics comic imprint, and the chapters were collected into a single tankōbon on September 27, 2008. While it deviates from the game's story drastically, it does reach the same conclusion; in addition, Viola, Falsetto and Claves do not appear at any point in the manga due to the condensation of the altered story, and the roles of Salsa and March are greatly reduced, with the two appearing only briefly and not joining the party.
