The protagonist of the story is a 15-year-old girl who is murdered but comes back to life with a strange left arm. Initially, she wishes to die and reunite with her foster parents, but Sudo convinces her to live and seek a new place where she can belong. She consistently relies on Sudo for support during missions and feels insecure without him, as suggested during the mission to destroy Nana. Although she initially despised her left arm for being a Chimaira, she later learns in a dream that her left arm belonged to her father, who had undergone Chimaira treatment. This revelation comforts her, strengthening her resolve not to become a monster and to use her arm solely to protect what she holds dear. Throughout the story, she maintains a close bond with Sudo, with strong implications that they care deeply for each other. Together, they betray the organization later on, and she survives its self-destruction.
