This second-year student appears as a tomboy and plays enough sports to have every team clamoring for her to join them, but indulges in a few feminine pursuits, such as a love of boys. She has a very straightforward and down-to-earth personality that sharply contrasts with the cheery and optimistic Nozomi. Her parents run a flower shop. Rin wears red-orange, and she transforms into Cure Rouge; her counterpart is her best friend, Cure Dream. For catching Pinkies, Coco gets a trumpet from her Pinky Catch. She introduces herself as "Red Flame of Passion, Cure Rouge!" (æƒ…ç†±ã�®èµ¤ã�„ç‚Žã€�ã‚ãƒ¥ã‚¢·ãƒ«ãƒ¼ã‚¸ãƒ¥!, JÅ�netsu no akai honÅ�, Kyua RÅ«ju!)
In the first movie, her counterpart is Dark Rouge, who is voiced by Miki Nagasawa.
