Totally forgot ^^;Not the first time tho. I remembered you're the one who posted f/z and knk collab which they obviously used her ost. She's like a guest composer in fgo due to these works which can be found in credits.
I guess its mostly that before Kalafina she was doing it with more fun, during Kalafina, with a sure source of income she felt like trying less + presure for steady flow of new jpop songs, and that showed, while now that she's independent she has to again put more efford into her music and im sure has more freedom too.I guess the spacecraft episode really did wake her up.
Eeeeh hopefully it's not too J-poppy. Same with the OP.Anyway, ASCA for ED
