Some interesting points:
yui is terrible at waking up early. She will hit the snooze button about 5 times before waking up. But having kids to take care of, she has no option.
While rehearsing, yui will tease mafumafu for having “chirichiri” hair. That’s how parts of the song “Chiri” came to be.
yui’s objective with FLOWER FLOWER is to have fun above all things.
In Powerful yui came up with the intro in acoustic, but she thought it was not cool enough, so she worked the final arrangement with the band members.
Sacchan admits he barely speaks on stage, so hearing him talking so much on radio is a rare event.
