>>45225691It's a cover song Polka is dropping tonight.
https://www.youtube.com/watch?v=U5Vftrd_qOIThe title is literally "Graduation Photo" using the same kanji that they use for VTuber graduations. So it gave a bunch of people a mini heart attack when she put up the frame earlier (myself included).
She probably chose this song and the timing because Japanese High Schools are having their Graduation Ceremonies this week so a lot of kids are leaving that part of their life behind and moving onto being adults.
