I was heavily frustrated about my crap very first GSSR result (rolled on Saber banner, only got Traptolfo, nothing else) thus I put all my hopes and some money on Summer BB's rate-up yesterday and ta-da! Kouhai came home! It took me 10 multi rolls to get her. I was very lucky with SR pulls too, got 7 in 10 multi rolls. (Parvati NP2, Martha NP5, Circe NP3, Caster Gil NP2, Beowulf NP3, Lobo NP5 and Astraea for RP because I have her at NP5 already) I regret nothing, money well spent I'd say. Now I can happily skip banners until Saber Musashi's rate-up from the 20M Download banner.
