Trip -innocent of D-

"Trip -innocent of D-" is a song by Larval Stage Planning that served as the second opening theme for the 2012 TV anime High School DxD (ハイスクールD×D), animated by TNK. Released in 2012, it appeared as the group’s third single and was issued by Lantis on April 25, 2012. The title track features music and arrangement by C.G mix.

Musically, the song is a brisk J-Pop piece with an electronic edge, driven by bright synthesizers, a steady beat, and a chorus that opens quickly into a high-energy refrain. Larval Stage Planning’s vocals keep the verses tense and forward-moving, then broaden the hook without losing the track’s momentum.

That blend of speed and tension fits High School DxD’s mix of school-life comedy and supernatural conflict, where Issei Hyoudou is pulled from ordinary life into battles involving devils, angels, and fallen angels. The single also included the coupling song "dramatic story" and off-vocal versions of both tracks, making it a four-track release.
