This is the fifth 5 Yuan box released by Little Frogs and the first in the Goddess Story series to have XR cards!
There are two versions of the 5M05 box, a cubic "normal" version and a rectangular "online" version.
The new rarity "XR" can only be obtained from the "online" version. XR cards feature vector art style artwork - take a look at some examples below.
Normal box contains 20 packs. In each pack there are 4 Rs, 3 SRs, and 1 SSR or above (8 cards per pack).
The Online box contains 18 packs. In each pack there are 2 Rs, 1 SR and 1 SSR and above (4 cards per pack).
The set contains 117 cards.
As much like the preceding 5 Yuan sets, this set continues to contain coveted ZR cards, but the new XR cards are actually harder to pull (One in every 16 boxes).
