So if I wanted to get Queen or Violet, is there even a way right now?

I’ve gotten some good 5 star characters like P3 Makoto, Ayaka Sakai, and Tempest riko (my current team) but I wanted to experiment with characters like the two listed above. I got riko and makoto through the limited banner, and Ayaka through some 5 star box.

Started like a month ago and was wondering if there’s a way to pull for these characters?
