What Soundtrack Features Themes For Gremory Scenes?

I get this question all the time when people want the music that plays during Rias Gremory moments — that romantic, regal, sometimes melancholic vibe. If you’re looking for the official sources, start with the core OST releases: the 'High School DxD Original Soundtrack' (season 1), the 'High School DxD BorN Original Soundtrack' (season 3), and the 'High School DxD HERO Original Soundtrack' (season 4). Those albums contain the leitmotifs and scene cues that underscore most of Rias/Gremory’s scenes — from intimate one-on-one conversations to the big, showy demon-family moments.

Musically, the Gremory-associated cues tend to share a few hallmarks: warm, sustained strings, a soft piano or harp line, and occasionally a low choir or horn that gives a noble, slightly bittersweet edge. When the scene is flirtier or tender, the arrangement leans on slower tempos and gentle piano arpeggios; when it’s dramatic or regal, the orchestrations expand into richer strings and brass. If you want the tracks that feel “Rias-like” specifically, look for slower, romantic-sounding pieces and those labeled as character image or vocal singles tied to her character — some of those singles and insert songs are also sequenced on the OSTs or on the singles released by the cast.

For actually finding them, Spotify and YouTube often have the OSTs uploaded (official or fan uploads), and CDJapan/BookWalker sell the physical CDs if you’re into liner notes and better audio. I usually queue the OST when I’m drawing or writing fanfic because those warm strings are perfect background fuel — they immediately put me back in the exact tone of those Gremory scenes, whether it’s quiet, flirty banter or a slow, emotional reveal.
