I could have done without them but in balance I'd say that the random ganbaruno was way less annoying than, say, those screaming goats in Thor: Love and Thunder. I mean they didn't completely ruin the experience of the video or anything

. Plus she and Yumeno did a great singing attempt at Kanashiki Heaven. Also, Marine anything = great.
EDIT: Seems you deleted your (unexpectedly touching) response but to clarify I don't hate her by any means! It's mild annoyance at worst really. We've talked before I think about how our overexposure to their various slogans and gimmicks can make them seem more played out to us than to the general public. They may have just a moment or two to make an impression on a casual audience, so whether it's gambaruno, or octopuses, or pandas, or just announcing how cute they are with every other breath (Nanamin), if that's what it takes then my hat's off to them.
