Due to her gentle and caring nature, Tsubaki is well-liked by all of the characters at Shibusen, able to get along with others easily, especially her egotistical and hyper meister Black☆Star. Tsubaki often provides help to anyone in need, and she acts like an older sister, or even a mother figure to some of the younger characters. She is also rather close with her family, even her brother Masamune, who had turned into an evil human but who manages to regain his humanity in his last moments of life because of her influence.
