APCM-5097: QUEENS ROAD -Gaiden- Oracion wa Moeteiru ka! ORIGINAL SOUNDTRACK

[Teioh]

Product and category were changed, but I'm not sure it is entirely correct. The OP is confirmed to be from the PS1 game "Queens Road", since the intro video is readily available. The music is probably from QUEENS ROAD -Gaiden- Original Drama Theater ~Is Oracion Burning!~
I can't find evidence that Shinnosuke Furumoto was in any way involved.

Queens Road Gaiden is a radio drama that was broadcast during the Shinnosuke Furumoto radio show starting in October 1996, five months before the PS1 game (which is just called Queens Road) was released: https://ja.wikipedia.org/wiki/古本新之輔のパラシュート遊激隊. This is the drama soundtrack.

I am not sure if the game's vocal themes were also used in the radio show, or if they're just on these two drama albums as a bonus. The "game version" subtitles on the other album may suggest the latter.
