In the manga, Ginko sees every living thing as bears, believing Kureha to be her fated one, as Kureha is the only one who appears human to her. Ginko assumes this is because the entire world is made up of bears and only she, her mother and Yurika Hakonaka can see the world for what it truly is, being descended from the royal family of the forest. However, it is later revealed that the "bear universe" is just a delusion implanted into her by her mother, Kale. She later regains her memories, remembering that Kale was responsible for the death of Reia and she tries to distance herself from Kureha.
