She is one of Tohru Honda's best friends. She is depicted as very perceptive; and conducts herself in a deadpan manner. She is considered to be scary by her female schoolmates; though Saki uses her reputation to shield Tohru from the malice of the Prince Yuki Fan Club. With her other best friend Arisa Uotani, Saki swore on Kyoko Honda's grave to look after Tohru, and in their "parental" protection of Tohru, noted by Kyo Sohma and Yuki Sohma, Saki is depicted as the overprotective mother-figure.
