Unusually Hard to Attribute
蜜桃2 is one of the few doujin sequels on this site where we can't pin down a consistent manufacturer — listings for Peach 2 credit different sellers inconsistently, unlike the Animefeast/YingKongShe/Art Cards releases where the brand is stable across the marketplace. What is consistent is the pastel "peach" visual theme continuing from the original Peach set, and sellers typically throwing in a random selectable metal card as a bundled extra.
FAQ
Do I need to own Peach 1 first?
No, it's a standalone sequel — owning the original isn't required, though collectors who have it often pick up Vol. 2 to continue the set.
What's the metal card extra?
Sellers commonly include one random selectable metal card as a bonus — check the current listing for what's offered.
