I've been going hard the spring revival event and have not gotten any of the 2 girls to drop for me. I've bought 7 recharges since the event started and use up every point that I get when I can and still nothing.

I know they are dropping for some, a friend of mine that I introduced to the game got both girls on the same day and only had to use 1 recharge to do it.

RNG is beating me like a Redheaded Stepchild.
