|Japanese name:||水無月 かれん|
Seen around school as cool and inspiring, most of the students look up to her. She, as Nozomi learns, is the most trustworthy Cure. In the beginning, she is reluctant to join the Cure team. In episode 6, as the girls are being manhandled, Karen stands up to her friends, vowing to protect them regardless of transformation. The butterfly that eluded her previously reappears and successfully lands on her wrist, enabling her to transform to Cure Aqua. For catching Pinkies, Coco gets a violin from her Pinky Catch. As Cure Aqua; counterpart of Cure Mint, she wears deep blue in her outfit, resembling Cure Mint's outfit. She introduces herself as "Blue Spring of Intelligence, Cure Aqua!" (知性の青き泉 キュアアクア!, Chisei no aoki izumi, Kyua Akua!) Like Nozomi and Komachi with Coco and Nuts respectively, she has a special bond with Milk.
In the first movie, her counterpart is Dark Aqua, who is voiced by Reiko Kiuchi.
