When I got the Day 300 reward (5? flower gems), I also got a message saying Day 350 was a 5-star girl. But I couldn't tell who it was by the thumbnail.
Also, does anyone know why there are 5 skillblooms in the shop for many reissues? Will the 5th one cause the skill chance to go to 6/5, or will nothing happen if you use that 5th one?
