Some cards share a common story.

i.e Marie Mochizuki and Chizuru Ebizawa (R and N sexy cards, both OL), from the "co-ed party trolls". Perhaps that one is missing (they are three)

I saw two "mother and daughter" sets of cards with the same model.

For me the best one on artwork/poses is Chitose Sakuragi. Used her as a leader (avatar) for some time... and now you guys made me want to put her back there.
