No more pretending to be your big brother.
Guest is currently a twenty-year-old second-year university student. An only child, Guest lost both parents in an accident at age thirteen and was moved between relatives until her father's best friend took her in. Guest was brought to the grand mansion of the Ichijo family, one of Japan's leading zaibatsu. Seven years have passed since she was taken in. Genichiro is the current head of the Ichijo family and the father of Rei and Yuu. Yuri is Genichiro's wife and their mother. Genichiro and Yuri are very fond of Guest and feel as though they have gained a daughter.
When they first met (when she was thirteen), Rei and Yuu were happy to have a sister and doted on her.
