The music was composed by Hitoshi Sakimoto , who had also worked on the previous Valkyria Chronicles games . When he originally heard about the project , he thought it would be a light tone similar to other Valkyria Chronicles games , but found the themes much darker than expected . An early theme he designed around his original vision of the project was rejected . He redid the main theme about seven times through the music production due to this need to reassess the game . The main theme was initially recorded using orchestra , then Sakimoto removed elements such as the guitar and bass , then adjusted the theme using a synthesizer before redoing segments such as the guitar piece on their own before incorporating them into the theme . The rejected main theme was used as a hopeful tune that played during the game 's ending . The battle themes was designed around the concept of a " modern battle " divorced from a fantasy scenario by using modern musical instruments , constructed to create a sense of atonality . While Sakimoto was most used to working with synthesized music , he felt that he needed to incorporate live instruments such as orchestra and guitar . The guitar was played by Mitsuhiro Ohta , who also arranged several of the later tracks . The game 's opening theme song , " If You Wish for ... " ( もしも君が願うのなら , Moshimo Kimi ga Negauno Nara ) , was sung by Japanese singer May 'n . Its theme was the reason soldiers fought , in particular their wish to protect what was precious to them rather than a sense of responsibility or duty . Its lyrics was written by Seiko Fujibayashi , who had worked on May 'n on previous singles .
