I think I might have been the last player to receive Alasie and first to receive Frida… Lol
Back when Alasie was available, I used a token and got Alasie alongside Ulmer with about 5 min before she disappeared. Then the other day, I clicked on the ? of the summon banner and saw Kunchen. I did my pull and Yes! BONUS summon! And to my surprise, Frida instead of Kunchen! I literally pulled her within seconds of her appearing!
