- Answer, the epic opening theme by Rekka Katakiri, and its remixes:
- True Hell on Earth, a remix of "O Fortuna" which plays while chaos reigns in the city when Maou takes over.
- Songs My Mother Taught Me, the song playing during Kanon's performance at the end of her route.
- Ride of the Valkyries deserves a mention, especially during Kanon's performance.
- Remnants of Truth, the piece which plays during the Bad End H-Scenes.
- Embrace, a calm piano piece which plays during the other H-Scenes.
- The Moment of Truth, which plays during the intense pursuit scenes in the novel.
- A remix of "The Moment of Truth" is the appropriately named The Grand Finale, which plays during the climax of the novel.
- Yuki no Hane, Toki no Kaze by chata is unique and fitting as one of the ending songs.
- And there's Close Your Eyes, the heartbreaking song which plays during the epilogue.
