Ayaka Kamiji

She has a very cold personality and sees the outbreak as a blessing that happened right when she was becoming bored with the (normal) path her life would take; one time, Aki witnesses her staring out the window at the infected former students and smiling. Like Takahito, she sees herself as a "chosen one" and doesn't hesitate to betray or kill others for her own gain.

It is revealed that Ayaka graduated from Megurigaoka High, the same school that the School Live club girls went to. In the class album found on an expedition, her name is written as "Kamimochi". After she succumbs to the disease, Ayaka is seen wandering around Megurigaoka High, prompting Aki to comment that her most cherished memories were probably those of her high school years.
