So I just got 28 SRs from Love Live SIFAS JP. What?
The ones I got were of Snow halation and Bokura no Live, for some reason, for Muse. I still don't have the Hanayo for the Bokura no Live set, but I got the Kotori, Maki, and Nozomi for it! I already completed the Snow halation set before I got these cards.
Then I got some for Aqours. Most, if not all of them were Aozora Jumping Heart, which completed my Aozora Jumping Heart collection!
And for Nijigaku, there was Rainbow Rose and Shioriko's initial SR, completing my for TOKIMEKI Runners and Rainbow Rose sets.
I'm not sure what are the requirements for getting these SRs, I think it's just logging into SIFAS JP during the 1.5-anniversary event. Very cool!
