Minazuki, Karen

水無月かれん

Karen is the team's eldest member. This third-year student hails from a wealthy family and serves on the student council. Her parents are musicians who frequently tour. She misses them but refuses to ask them to return home, fearing it would disrupt their work; thus, despite her wealth and popularity, she is often lonely. Komachi is her best friend and a fellow student council member.
Viewed by most students as cool and inspiring, she is looked up to by the school. As Nozomi discovers, she is the most trustworthy Cure. Initially, she is hesitant to join the Cure team. In episode 6, while the girls are being manhandled, Karen stands up for her friends, vowing to protect them regardless of transformation. The butterfly that had previously eluded her reappears and successfully lands on her wrist, allowing her to transform into Cure Aqua. For catching Pinkies, Coco receives a violin from her Pinky Catch. As Cure Aqua, the counterpart to Cure Mint, she wears a deep blue outfit that resembles Cure Mint's. She introduces herself as "Blue Spring of Intelligence, Cure Aqua!" (Chisei no aoki izumi, Kyua Akua!). Like Nozomi and Komachi with Coco and Nuts respectively, she shares a special bond with Milk.
In the first movie, her counterpart is Dark Aqua, voiced by Reiko Kiuchi.
