For anyone that is looking for Princess Anemone and has gems to spare there's a gacha available that includes roughly half of the 5* and 6* Knights that were a part of the 10/19 rework (Ume, Princess Anemone, Ixia, Fire Lily, Devil in a Bush, etc). Each of those Knights has increased odds of being rolled in the gacha itself and after spending 250 gems you get a ticket that can be cashed in for any one of those Knights as well.
