Some of the BGMs I remember hearing exclusively in the anime are:
- the Anime Kagari Theme
- Sorrowless except the percussion part is taken out (playing in sad Kotori scenes)
- End of the World in piano
- introspective piano music in Episode 14
- Innocence Eye (we all know what this is now)
- a seed leaf (wait what this isn’t in the album???)
- Nirinsou except the percussion part is taken out
- acoustic guitar music in the vignette scene in Episode 18
- Retribution arrangement
- Last Desire in piano
Since the album listed twelve anime-exclusive OSTs, I definitely missed out on some stuff (that or there were tracks that weren’t included). As for my guesses, the most obvious one is perhaps Anemone being that Nirinsou arrange. I have a gut feeling that Aogarebyou is that Retribution arrange, but I could be wrong.Yume could either be the EotW piano or the introspective piano piece. Sinner sounds like it could be the Last Desire piano. Some have said that Bloom is likely the Anime Kagari Theme, which I agree.
Okay I’ll go back to studying now.
((btw I found out that the Kari arrange in Episode 13 was from the Selene album lol))
