Chizuru is the socially awkward Relife test subject. She is on her second year as a subject after her first year didn't go well. She makes an effort to make friends, but her lack of social awareness and creepy smile makes it difficult for her. She does manage to get top grades in her class. Over the course of the year she falls in love with Arata as well as figures he is another test subject. After graduation she joined ReLife Laboratories.
