The EX box of the current event gacha is renewable AND gives 100 5* and 6* aqua fragments. Best source of aqua fragment at the moment. Time to burn stamina potions and skip tickets to make a great stock of aqua crystals. There is one petite centy too.
The new 6* Win is a world flower incarnation. I think it's different from the Witches. She works exactly like Bloss. Not good, not bad. I kinda like thoses girls. They can be really strong but with a huge drawback. It's better than the Ancient Knights being just broken I guess.
I really liked Bloss (on her art side) but not than much Win. A tiny bit way too White Rose Loli for me. Though, I can't wait for Banana Island world flower incarnation.
