Takae was a third-year student at Megurigaoka High School, and in the same class as Yuki. Takae, along with two other girls who were their classmates, would usually hang out with Yuki.
As Takae was officially infected before the start of the series, Takae only appeared as a supporting character in "Yuki's delusions." It was seen that Yuki "talked" with Takae's choker when 'interacting' with her.
