Description
Ryôko Kuriba has vertically striped hair alternating between light and dark shades, featuring a distinct dark stripe at the center of her frontal fringe. Her yellow eyes contrast with a darker section across the right side of her face, a remnant from surgical separation during an experiment. She typically pairs a black-and-white school uniform with a lab coat and wears swirly glasses when working independently.
As a child, she survived a building collapse due to a lung transplant from her mother, leaving her mother permanently weakened and vulnerable to infections. This trauma propelled her research into cyborg technology to save her mother. Before Academy City, she gained renown studying animal development, particularly the impact of body structure changes on intelligence in owl parrots and gentoo penguins. Her ape intelligence research yielded therapeutic finger exercises for emotional and behavioral disorders, adopted nationwide in Japan and securing her Academy City invitation.
Driven to cure her mother, she volunteered for the Total Human Cyborg Replacement Project. Surgeons split her body into two halves, replacing missing sections with machinery to form separate cyborg entities. After a year apart, both halves successfully reunited without psychological rejection, retaining memories from separation. However, discarded mechanical parts assembled into a sentient doppelganger that initially believed itself the original Kuriba until detecting memory gaps.
Kuriba embraced pragmatism, accepting necessary sacrifices for her goals. When researchers dismissed her warnings about the doppelganger’s escape risk, she created and distributed Indian Poker—cards recording and sharing dreams—hoping someone in Academy City would devise a way to erase the doppelganger’s artificial soul. She deliberately circulated a card containing her own knowledge to enable this. During the Dream Ranker incident, she avoided involving outsiders like Misaka Mikoto until targeted, forcing a confrontation.
Aboard a data storage airship, she offered to erase her own soul to gift the doppelganger her human body, declaring her life valueless once her mother survived. After the doppelganger rejected this and demanded her death, Kuriba leaped from the airship in a suicide attempt but was rescued. Later, she was accidentally shot by the project chief during a standoff. Near-fatally wounded, she survived using components from the destroyed doppelganger.
Post-incident, the doppelganger manifested in Kuriba’s dreams, recounting precise battle details with Mikoto—information Kuriba lacked. It clarified its demand for Kuriba’s termination stemmed not from malice but as a "necessary condition," mirroring Kuriba’s own outcome-focused pragmatism. It cautioned against suppressing this trait, warning it would stifle her creativity. Since then, the doppelganger critiques her research in dreams, advancing her cybernetics work.
Her technical expertise spans safety limiters for cyborgs, artificial muscles using chemical reactions, and suppressants for cybernetic rejection. She developed cyborg countermeasures, deploying them to evade her doppelganger initially. A mug gifted by her mother before entering Academy City remains among her possessions.
