Yukie is an intelligent, caring girl. She is best friends with Haruka Tanizawa.she is a member of a non-distinct group of girls referred to as "the neutrals." Yukie has natural leadership skills and is a model student, as well as being the female class representative. She was described as outgoing and kind. She is best friends with Haruka, and has a crush on Shuya Nanahara whom she met in elementary school in April on a rainy day while trying to organize the volleyball and little league teams in the gym. She and Haruka worked well together on the volleyball team and Yukie was the setter. She was held in high regard by most of her classmates, as both Shinji Mimura and the proud Takako Chigusa considered her to be trustworthy. She was often a better leader than the male class representative Kyoichi Motobuchi, this is shown especially in the Program.
During the game, she gathers Haruka and several other girls and hides in an abandoned lighthouse. Hiroki delivers Shuya and brings him in.
Yukie came up with the plan to gather as many of the girls as possible together, and have them think things through and try to work out a way off of the island. She manages to get Haruka Tanizawa, Yuka Nakagawa, Satomi Noda, and Chisato Matsui. She and the rest of her group find a lighthouse and lock themselves in. A scout discovers Yuko Sakaki . After Hiroki Sugimura delivers an injured Shuya Nanahara to the lighthouse, Yukie takes care of him and dresses his wounds; she also convinces the other girls to let him stay. When Shuya awakens, Yukie tells him who has died while he was out. Yukie mentions that Mizuho Inada, Kaori Minami, Yuichiro, Tadakatsu, and Toshinori died. Yukie then asks about Tatsumichi Oki and Shuya tells her that it was just an accident and that he was with Shogo Kawada and Noriko Nakagawa. He also tells her of Kawada's plan to escape.
