Dark Cure La mer aka Laura was searching the grand ocean looking for Manatsu aka Cure Summer but Manatsu wasn’t able to transform because Dark Cure La mer took away her transformation device and put her into a cage and somehow Manatsu escaped despite being underwater.

“Where are you Manatsu..”

Dark Cure La mer says as she looks around but Manatsu was actually hiding behind a rock and Dark Cure La mer couldn’t see her.
