First μ's costume set that I completed! FRUITS Really took me a long time to get Rin's card. She was stuck in her school uniform for 4 months until February came and I got her SnowHare then Dancer and lastly Fruits.
The first set was actually Waku Waku Animals but since most of them are event cards, I couldn't call it completely as an achievement.
For Aqours, Maru's still missing her KimiKoko costume.
