An idol could have tweeted that Kita's message and it would practically use the same words, almost indistinguishable.
Absolutely hate agreeing with SO for once in my life, but yeah, I know Bocchi practically has cartoon powers and some kind of reality bending, but there is only so much you can suspend your disbelief at she standing right there and people that are supposed to be fans of the band, that aren't #1 and #2, not being able to tell who she is. Her guitar solos aren't exactly subtle. And how many people they know with pink hair? Or they just see 2 floating cubes and think is part of the decoration of the stand?
