Natsuki Rin

Rin is one of the official characters of the Pretty Cure franchise and one of the main Cures of Yes! Pretty Cure 5 and its sequel, GoGo. Her alter ego is Cure Rouge (キュアルージュ).

Canon
Rin has a very straightforward and down-to-earth personality that sharply contrasts with the cheery and optimistic Yumehara Nozomi, which is shown that she has a big-sisterly attitude toward her best friend. Though many people think of her as tomboyish, she indulges in a few feminine pursuits. Throughout both of the seasons, Rin shows a passion for accessory design, usually the one in charge for designing what Natts House is selling. Rin has openly admitted that the thing she is most afraid of is losing her loved ones, most noticeable Nozomi. Beside of that, she also has a fear for unnatural things, and when she was a child, used long time to recover after getting startled but when she and Nozomi were little, she found Nozomi crying and comforted her. Nozomi did the same too, when Rin was scared. Sometimes, when Rin runs into some troubles that really frustrate her, she could become hopping mad, especailly with her favourite sports, such as soccer.
