Yuuki is a second-year at Fujimi High School. She is regarded as the sexiest student in their school.
She was known to have some "strange talk" surrounding her at school. She escaped with Fujimi Academy's other survivors and stayed with Shidou's group, finding pleasure in their debauchery. She has been manipulated like the others that was in Shidou's group. She helped Shidou enter the Takagi compound by using her sex appeal, but she was forced to leave like everyone else that came with Shidou. She has also survived the accident Shidou had after the EMP and had subsequently escaped. After that, she is later seen at the school where the evacuation is taking place.
