Yes, I mean Siren. It was shown that she lost the ability in episode 21, but that may be because the power was stored in the necklace from when she was born and the energy from that necklace went in to her becoming a Cure instead. And didn't she have the necklace during flashbacks of before she joined Mephisto?
