Asuka Nagano (明日香 長野 Asuka Nagano?) is 17 years old and a complete perfectionist. She dislikes working with others because she feels that their flaws bring her down. Asuka hates making even the tiniest of mistakes and tried to encourage others to be perfect as well, but it usually comes across as her being mean. She almost never shows any outward signs of joy, except when she is playing her violin. As Cure Aria, she introduces herself as "One who plays to perfection, Cure Aria!". Her theme color is green.
"One who plays to perfection! Cure Aria!"
"Kanpeki ni hatashite iru ichi! Kyua Aria!!"

- Asuka is the fourth Pretty Cure to play a musical instrument, after Karen Minazuki, Hibiki Hojo, and Ellen Kurokawa.
- Asuka is the second Pretty Cure to play violin.
