Yumehara Nozomi is a second-year student at L'École des Cinq Lumières Middle School, Nozomi appears to be a typical shoujo heroine, and does know what to do with her life. She has a habit of saying "It's decided!" (決定！ Kettei!?) when she decides on something not exactly with everyone's permission. Her alter ego is the Cure of Hope, Cure Dream (キュアドリーム Kyua Doriimu?).
Nozomi is a rather cheerful heroine, and although has no talents in anything, she has her own sense of justice and is, through all of her annoyances, a great friend. She formed a crush on Coco's human form at first sight, and although it was just weak flirting at first, her feelings grow as the series progresses. Though her teammates are vastly different from her, Nozomi uses her cheerfulness and sympathy for others to become their friend and their leader.
