Tsubomi Hanasaki 花咲つぼみ

She is a second-year transfer student at Myoudou Academy and is in the same class as Erika. Tsubomi's alter ego is Cure Blossom. Tsubomi is a shy and timid introvert who usually keeps to herself, hesitant to speak openly unless approached first. She often worries over small things and is easily worked up, especially when scared or trying to handle more energetic people like Erika. She strongly wants to shed this aspect of herself and over the series manages to become more easygoing and willing to speak her mind thanks to Erika's friendship and encouragement, until she became confident enough to accept her negative qualities.

Tsubomi is a kind girl as well, and would never say anything to hurt anyone or make them feel as though she depended on them if it could make them unhappy. She loves flowers and dreams of becoming a botanist to spread flowers and make people happy.
