When she first appeared, she was cold and disrespectful to her elders (Hibiki and Kanade) and very mature for her age. But behind all that coldness, she is a sweet, loving and caring girl and sometimes likes to have a little fun and loves singing.
She loves her parents, but hates it when fight and wishes them to stop and took the choice of doing it herself. She loves her father very dearly and even transformed into a Pretty Cure for him. But, when he does awkward and gushy things she tends to get flustered.
There are hints that she might like Souta as he is her only friend before she became friends with the Pretty Cures. She is often shown with him.
