Tsubaki, Kureha

椿輝紅羽

Daughter of Reia and a Matagi hunter.
In the manga, she is a transparent high school girl. She is not literally transparent; she simply fails to leave much of an impression. From time to time, she sees the same "dream" repeatedly: a human girl in a bear costume. One day, she assumes that one of her classmates is truly a bear. She becomes friends with Yurishiro Ginko. As a child, she was bullied by her classmates. After removing her hair tie and glasses, her classmates notice the change and get on friendly terms with Tsubaki.
In the anime, her mother was mauled by a bear eleven years ago. Since then, Tsubaki has hated bears and pledges to kill any she sees. 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 meets two new transfer students, her attitude softens toward them over time.
