Role in the Series:
Tsubomi will meet Sonja and her Friends in Sonja's Adventures of Heartcatch Precure. She is Sonja's best friend and they get along really well.

Tsubomi is a really shy and introverted girl and admits that she does not handle energetic people like Erika very well, but loves flowers very much, and dreams of being a botanist. Due to her relationship and frequent visits with her grandmother, she has picked up her old-fashioned speech pattern.
Tsubomi has stated that she plans to change her personality now that she has started in a new school. Although still insecure, she is starting to speak out her mind and preferences. Together with the courage of Erika, Tsubomi is slowly but steadily changing to a more confident person.
