Daughter of Reia and a Matagi hunter.
In the manga, she is a transparent high school girl. She’s not really transparent, she doesn’t leave much of an impression. From time to time, she sees this “dream” over and over again. Seeing the same human girl in a bear costume. One day, she assumes that one of her classmate is truly a bear. She became friends with Yurishiro Ginko. She was bullied by her classmate as kids. After taking off her hair-tie and glasses, her classmates notices her changes and goes on friendly terms with Tsubaki.
In the anime, her mother was mauled by a bear eleven years ago. Since then, Tsubaki hated bears and will pledge to kill every one of them at her sight. Her only true friend and lover, Izumino Sumika, was also mauled by a bear. She does not want to be anyone’s friend ever and will never join the “Invisible Storm.” When she met two new transferred students, her attitude softens over time for them.
She regains her memories of loving Yurishiro after the complex events. She realized that she had truly loved her from the start. Tsubaki accepts the fact that to get her “Promised Kiss” with Yurishiro, she must become a bear. Kumaria granted her wish and she transform into a white bear. She and Yurishiro shared the “Promised Kiss”. “No ones knows where they go but, let’s leave it that way.”
