While Keitaro is abroad, she's a girl who comes to the Hinata House. She's Keitaro's younger sister, but they're not blood related. Disguises are her strong point, and she also has knowledge of martial arts. When she was a child, as expected she made a 'promise' with Keitaro. She has a pet, a cat named Kuro.
