Yoko Kurama and… uh… girlfriend, Rinako. Sorry. I didn’t know about Maya when I made Rinako up. Maya is a girl from the manga Two Shots, about how Kurama and Hiei met, and she had a crush on Kurama but he was forced to delete her memory to keep her from remembering the danger she fell into when an evil demon kidnapped her. So she forgot about him, too.
So Rinako is half Japanese, one quarter Canadian, and one quarter water demon. (What? Even Yuusuke, the hero-nerd, has mysterious demon blood that suddenly manifests itself, I’m told, in season 3 or so) She comes over to finish high-school in Japan, meets the gang, helps Kurama escape from something, learns martial arts and how to use her innate powers, which for some reason includes ‘light’ as well as ‘water’, blah blah blah, and also she plays violin.
