You forgot Queen Rosa Novalis who jumped from 3* to 6* too. And I think that's all. Casablanca is still waiting a 6* version (of she isn't the Banana Island Queen? If so, who's the Queen of all the bananas?).
Cepha is definitively the best one of the starter girls. And a good one with nice pursuit and a lot of weakness damages. I hope there will still be the 150 FG special gacha with featured 6* ticket next year for her.
Also, the new reissue shop system seems just a tiny bit broken with equipments. For just 5 stamina, you got 1000 currency. And for 100 currency, you can get up to 99 of any equipment. Considering that Anniversary & final bosses equipment (espacially rings) are better than every other event equipmement, you can just you can just buy a bunch of them for almost free and give best rings to all your waifus. (and it definitively makes equipment gacha and regular raid bosses totally useless, even for day one players).
I know equipments are not that great but more stats is always better than less stats.
