HOWEVER i have gotten one of the 4 girls. The red haired one with the hat. Went to explore, got a few pseudo streaks, got her when the chance time finally happened. Showed me the card and all, but when i look in my list she is not there :<
I guess that might be because she isn't even in the damn card list at all, though. Unaquired or aquired

Edit:
Used an R ticket and got Shino Takase, who has absolutely no picture and does not show up in the list either. Sheesh

Sounds like what happened last week with the daily login reward card bug (Azumi Isshiki dissapeared when you retrieved her, and she wasn't included in the card list neither). Try sending a support ticket, I guess that many players will have the same issue during these hours if Nutaku didn't update the card list. Chances are, that Nutaku is already aware of this issue and will fix it asap.

I've read that slayer cards should be released just before the event itself, so that's kind of a good signal, after all.
