One of the most interesting aspects of cards in Bang Dream are the different girls making appearances in each others' cards. It's one of the biggest appeals to the card art, so I decided to compile data on how often each girl made cameo appearances.

Some observations:

• Ran, Hina, and Chisato are tied for having the most cameo appearances, at 22 each.
• Yukina has the least amount of cameo appearances, with only 6.
• Arisa has the most in-band cameo appearances, with 17 cameos in other PoPiPa cards.
• Yukina, on top of having the least amount of total cameos, also has the least amount of in-band cameos. This becomes even more interesting after you realize that all of her cameos are in-band.
• Hina has the largest amount of cameos outside of her band, having 12 out-of-band cameos.
• Yukina, once again, has the least amout of out-of-band cameos. She has 0.
• PasuPare has the greatest amount of cameos as a whole, with a total of 92 cameos between the five members.
• Roselia (probably thanks to Yukina's influence) has the smallest amount of cameos as a whole, with only 59.
• Kaoru is the only character that has had cameos in the cards of members from all five bands. And, as mentioned previously, Yukina is the only character without a single cameo outside of Roselia cards.

Note: In cases where a girl appeared as a cameo in both the untrained and trained versions of the card, it would count as two seperate cameos. For example, in this card, as Aya appears in both the untrained and trained versions, it would be counted as cameoing in a PoPiPa card twice.
