Urara Kasugano is the youngest Cure of the group in Yes! Pretty Cure 5 and its sequel. Her alter ego is the Cure of Effervescence, Cure Lemonade.
Urara always acts cheerful to people wherever she goes, but is shy until she meets Nozomi, who acts as her friend instantly when they meet. Urara is a bit materialistic and takes her job seriously, but because of her busy lifestyle, she had no friends when she begins at her new school. Because of her fire for her job, she is very calm and polite, referring to most of Pretty Cure with the suffix "-san". Even so, Urara's personality does resemble Nozomi's. The two sometimes don't think their actions through, causing together problems and giving Rin a hard time, who has to look after them half the time to try and stop the two friends from causing problems. Urara also has a very large appetite and loves food, and she and Nozomi sometimes pair up as both friends and Pretty Cure, although their friendship isn't quite as strong as Rin and Nozomi's.
Lemonade Flash - Cure Lemonade holds out her hands, then puts them to her chest. Her item appears in front of her, she holds out both her hands and releases a cluster of yellow butterflies, which fly above her and attack the enemy.
Lemonade Shining - Yellow light from Cure Lemonade's butterfly bow shines, whereas the light follows her right arm. When it has reached her fingertips, the Lemonade Castanet appears. The item opens and closes, and like her first attack, she holds out her hands, then puts them to her chest. Her item appears in front of her, she holds out both her hands and releases a cluster of yellow butterflies, which fly above her and attack the enemy.
Prism Chain - Cure Lemonade makes fists with both hands and crosses them in front of her chest, causing a butterfly-shaped emblem to glow with her signature color. Cure Lemonade's hands glow yellow and a chain of butterflies is formed. She sends out the two chains as whip to hit or grab the enemy.
