Aye.
I don't remember how much I've mentioned, but the story this time isn't directly about Amy/Elma and only involves them in the form of someone trying to plagiarize from their music, which is likely the basis behind the new styles present and why a song from a prior album, "Bakudanma," is showing up again. There'll also be an associated 130-page novel if I remember correctly, which'll be one heck of a journey for the fan translators, assuming Yorushika doesn't hire translators themselves. There's also going to be another album coming out soon based on the lack of appearance of two other songs, that being the end credits for Nakineko (https://www.youtube.com/watch?v=_shJD_wXXfw) and a commercial for a Japanese construction company in Burma (https://www.youtube.com/watch?v=q_CxRQ9bvjU).
Apparently, there was a time where n-buna, the composer for Yorushika, wrote a whole song daily, so two albums like this doesn't seem to be nearly so extreme—
