Sympathy

"Sympathy" is a song by the Japanese music unit Larval Stage Planning and the opening theme for the 2012 television anime High School DxD (ハイスクールD×D). TNK animated the series, and the song was released as the standalone 2013 single "Sympathy". C.G mix composed and arranged the music, and 朝見凛 wrote the lyrics.

The song is built as a brisk J-Pop theme with a strong beat, polished electronic textures, and a chorus that expands the tension of the verses rather than softening it. Larval Stage Planning's performance keeps the melody sharp and driving, giving the track a clean sense of momentum from its opening bars.

That sound fits a series that moves from everyday school life into conflict among devils, angels, and fallen angels. As the anime's OP, "Sympathy" frames High School DxD with energy and pressure, matching the show's blend of youthful comedy, supernatural danger, and fast-moving confrontation.
