Dark Cure appears in Hanasaki Tsubomi's dream, where she fights against Cure Moonlight before the Great Tree of Hearts. Although hurt, Dark Cure manages to get the upper hand in the battle, and succeeds defeating Cure Moonlight HPC01. She is later seen beside Sabaku whenever a Desert Apostle has audience with him, acting as his second-in-command.
In the preview for the tenth episode, Hanasaki Tsubomi and Kurumi Erika claim that Dark Cure has lost her heart HPC09, though it is unknown if this will have a deeper meaning later on. In the thirteenth episode, Dark Cure says to Tsukikage Yuri that she is her. She claims that she is the "shadow" of the moon, and that Yuri is the "light" of the moon. She is desperate to destroy Cure Moonlight once and for all, and will not remain calm until she manages.
