I can't say I have one list of wanted girl. It's more like two list. One really short with wanted and needed girls and one with only girl I wish I'll get someday.
So, let's go.

Want&need list:
Miko Pink because she is one of the best 5* counter.

Obviously she is the main target for that 5*stoneticket from the anniversary campaing. And she will get the dressbloom from that same campaign right after.

Wished but not needed list:
With no actual order:
Mint, because I like her since I started to play but she is just useless as 2*.
Tall Stewartia. I have her on Nutaku and she just make a great job on Whaleship. And she is like a mini-Kerria so, that's cool.
Dahlia. Drawn by Moneti + beautiful girl.
Rose. One of my first favorite 5* when I started on Nutaku and I got her really early. Ijust ant her on DMM too.

Wished/Needed and already got list:
