Yae Yatomi

Commonly known as “Yaya” or “Yayako.” She appears to be suffering from asthma, but it was found out that she was actually suffering from Mineral Dust Allergy that is caused by pollution in the Industrial Center, where she lives. Yaya seems to be recovering after the trial. She appears to be infatuated with Mayuki and can sometimes be seen competing with Minori over Mayuki’s affection.
