Polka, you're the Yukimin #1. You helped expressed the feelings of excitement we had for Lamy's solo concert. Plus it honestly really did liven up the concert lol Lamy's 2nd Anniversary goods include official Yukimin certificate and card. The numbers given are random but I hope if Polka does decide to purchase one (could totally see her buying the whole Anniversary set) her card number says she's Yukimin number one.
