Note 1: Aki's 3D birthday stream was delayed for a month because of Bloom, and on the day of the stream Youtube was unusable for many people
Note 2: Suisei's birthday and anniversary are the same day, she did a countdown stream for members only so superchats for that aren't visible
Note 3: Subaru's was also a 1 million subs celebration, no countdown since it would've been on the day of Coco's graduation
