Kamishiro Rui and Kusanagi Nene were childhood friends for the past 10 years, ever since she was 6 and he was 7. She was always the more socially anxious type, while Rui was an outgoing person. Nene was a vampire, but only her family and Rui knew, as she would get killed if anyone else found out. He had known that she was a vampire ever since they were kids since she was careless back then and showed him her little bat form that she could transform into, thinking it was cool.*
