35k stars, saved since the start of the server specifically for this purpose, and no Sayo. Did manage to pull two dupes, however, despite only owning 2 4-stars. In total that puts me at around 45k stars spent on gacha, 10k for Yukina's 4-star and 35k for Sayo, and none of the desired cards received. At this point I'm just glad the game was generous enough to give me a copy of the '4 People at the Cafeteria' Yukina card, because hot damn I don't think I got any other card that I even wanted in this whole scouting fiasco.

Needless to say, I'm salty af.
