A first-year student at Nijinokuni Academy, Aimi is slightly timid and soft-spoken who is a part-time gardener and a secret lover of romantic movies. Always full of emotion and compassion, she always puts other people in front of her, even if they are bullies. Aimi ironically doesn't believe in flowers, chocolate, or greeting cards; instead, Aimi believes in true love, the type of love that doesn't require items to express one's love for each other. She believes everyone has a good heart, no matter their background. As Cure Blush, she harnesses the power of all kinds of love, and can read people's emotions just by looking at them. Blush can also attack by using her Rose Harp to generate either gusts of pink wind, pink heart-tipped arrows, or as an attack breaker. Her finishing attack is Blushing Burst, and she is the guardian angel of love.
