Karen Minazuki

Karen Minazuki is one of the five main cures in Yes! Precure 5 and Yes! Precure 5 GoGo!. She is a third-year student and the student council president of L'École des Cinq Lumières middle school. Karen's alter ego is Cure Aqua, the Precure of Intelligence.

Karen is strongly admired for being calm and stoic, a mature young woman who has come to cover up her insecurities and feelings of loneliness. She dearly misses her parents as they are usually away, but out of obligation and feeling that everything rests on her shoulders she refuses to let it get to her, she has come to think she needs to do everything by herself. She was originally very enthusiastic about being class representative prior to meeting Komachi, but by the time it began wearing her down she was forced to keep going to be there for her. Because of her position, Karen is able to memorize all the names and faces of all the Cinq Lumières students, and also easily takes responsibility when something happens to the school. While usually calm in temperament, when pushed enough she can sometimes get to a point where she ends up saying hurtful or offensive things to other people.
