If I remember correctly, a few regular students did appear in the background of the anime.
Oh well, it feels so weird to have a SS in EX and a SA in Hard (probably forgot about Hard when I was playing Anemone Heart).
Also, since everyone is doing SR and UR counts, I have:
3 URs
of those URs I have 2 event URs (Swimsuit Eli and Snowman Kotori)
and 1 normal UR (China Dress Kotori)
8 idolized SRs
3 event SRs (the Maki and Nico SRs that came aroudn christmas/new years time and a Hanayo for buying a magazine)
32 normal SRs
As stated already, getting SRs is easy, just play a lot of events, but getting URs is incredibly difficult. On of my friends is rank 175 and has yet to draw a UR yet.
