Ok, so I tried the new "5654" and idk if it worked... I did get her though. I got 5 of each character in a locker, so they all had a lewd face in the book.. then I saw her, she's golden.. you can't miss her.
Found out the 0 is a 6.. I'll try that
There is a code in the book. 5054... I tried 2 sets of lockers with 6, and made a girl get placed in them in order.. but so far nothing..
