Riho Yamazaki

Riho Yamazaki's parents were killed as a result of a nightbreed attack. Alone in the world, she became the ward of Tatsuhiko Shido, as well as his secretary. Riho has a big crush on Shido, and is often jealous of Yayoi's attentions, and has become the target of Guni's taunts because of her often naïve nature. At first, Riho is unaware that Shido is a vampire, but even after she found out, she stayed on. Later, on another case, Riho was seriously injured by Cain, when he cut her and left her to bleed to death. As the life was ebbing from her, Riho asked Shido to drink her blood, knowing that she would become a vampire as a result. Shido complied reluctantly. Now a vampire herself, Riho now aids Shido in his quest to rid man from the threat of the nightbreeds. Her powers are just the same as Shido and Cain. However, due to her inexperience, Riho is not as adept as them. Despite this, she retains her optimistic outlook at life – as well as making a terrific cup of coffee.
