네임리스 ~ 당신이 기억해야 할 단 한가지의 것 ~

Eri is an ordinary looking freshman who attends Crobi Academy. With her parents working as researchers overseas, she is left all alone at her grandparents' house after her grandfather's death. Left by herself, Eri continues to obsess over her ball jointed dolls; a hobby she's unable to tell anyone about, even her friends.
