While I feel like my collection still has a far way to go, I also feel like it's grown quite a bit since I started browsing these forums, and seems quite sizeable! I think back then I just had 4 Tamas!
Here's the ones that aren't in their cases, they're the active roster:
The seller for the yellow Angel didn't have the original box so she gave me a P2 box instead
That's why I have 2 P2 boxes but only 1 EN P2.
