Have just finished the season. Really feel like I was being trolled by that. Ep.1 credit =A=.
So far, all tracks that sound likely to be hers are
Eri’s tracks (13&18) from episode 3,
bright traditional instrumental track (Samisen?) at the beginning of episode 4,
arrangement of Asa ga Kuru (12) from episode 6,
piano track (10, either the conversation is too loud or the track is too soft. I barely heard it even when I check it again after seeing Grunty’s comment.) & mysterious traditional instrumental track (Erhu?, at 14&20) from last episode.
It seems that one of my guess is correct - most of her tracks are mainly for the female villain.
I guess we may get like 5 tracks again? Compared to the first season, they’re clearly less outstanding in the show, but it’s better in the sense that all of them weren’t arranged from a single main melody. (Bad twist - some of the above are Shiina’s and the pieces that I think they’re from the same track are from different but so similar tracks =w=.)
