Kuu just made a post about today and casually dropped some info again.
It was a very tiring recording today.
Yukiko Tanaka, her former background singer for past tours, joined her - she's not only her English teacher now, but she's also looking after the background vocals for the tour. So I assume she's back for re(live)!
Kuu also shared her day schedule again:
Lyrics validation
Meeting for tour goods
Recording
Break
Composition meeting
Fixing make-up
(and in between she watched the show)
My guess is that the composition meeting and maybe also checking the new lyrics was with Yukiko.
Maybe writing Kuu on her Insta in Japanese that she needs to work on her English lyrics helped.
