The Golden Case (黄金 の ケース Kogane no Kēsu) is a special box that keeps the Legendary Pieces safe. The item's purpose is to keep the Legendary Pieces safe from the hands of Dark Star so the Cures can find the Legendary Items. It's first appearance is in Episode 3, when it appears on Akari's bed.
The Golden Case has many functions like keeping the Legendary Pieces safe. There is other function it can do which is teleporting the girls to different worlds, giving the girls their upgrade attacks and granting them wings to fly so they can dodge attacks.
- This is the first special box in the Pretty Cure universe to appear in thin air on a Cure's bed and the mascots having no idea how it functions.
