An extremely shy girl. A high school sophomore at a combined junior and senior high school. She is plain and lacks presence. She is cold and dry toward others, with robot-like, sparse emotional changes. She always maintains a prickly attitude because she wants nothing to do with people. Since school rules require everyone to join a committee, she belongs to the library committee. During committee hours, she slacks off by sitting in a corner of the library prep room reading. She has never had a single friend and actively avoids others. Having lost her parents at a young age, she was shuffled between relatives who physically abused her, leading her to distrust everyone. Consequently, she knows nothing of human kindness. She has completely closed off her heart and is constantly on guard. She doesn't believe anyone could ever understand her. She hates people from the bottom of her heart and is deeply cynical. If someone is kind to her, she immediately suspects an ulterior motive. She believes everyone only acts out of self-interest. Perhaps because she has had to protect herself for so long, she is quite calculating and skilled at lying. While she hates it when others lie to her, she believes lying for her own sake is acceptable. Throughout her life, she has manipulated others through lies to protect herself. To Emu, everyone else is just a pawn or a convenience. Her worldview is centered entirely on living for herself. Because of her lifelong misfortune, she resents the happiness of others. She especially dislikes smiles or happy expressions and even harbors a slight desire to ruin other people's happiness, though she never actually acts on it. She currently lives alone. She is about 170cm tall, which is quite tall for her age.
