Nakuru is a transfer student as well, this time in Touya's class. She is very good in sports, and seem to have an interest in Touya. Even though Nakuru dresses like a girl, Nakuru actually isn't a girl. In fact, she said she isn't even human! She is hinting something at Yukito about Touya and Yukito himself, but she's definitely keeping a lot behind. Her true form, Ruby Moon, looks like a woman dressed and red and black, with wings behind her.
