Fun and semi plausible rrat... goomba is in japan right now. The schedule kinda lines up with her usual 8pm est time.
No reason for her to be there...except maybe to be there for the big concert and watch it all live as it happens in the studio cuz shes a fucking artistic chameleon and wants to learn the way. Pretty sure the travel status rn would allow her to enter the country as a worker
She certainly has the funds and ability to chill in jp for a while before the event if she wants, and considering her an calli get along so well it wouldnt surprise me if she just fucked off overseas for a bit cuz why not? Shes not exactly known for telling us the details of her endeavors until after the fact, so for her to pull some big shit like that out of nowhere wouldn't be too shocking for chumbies
