Ringo Ōhoshi is a nuclear physicist and a member of the Seven Prodigies.
Ringo's eyes are chocolate brown and her hair is light brown, falling just past her shoulders.
Preferring to live in isolation in space, Ringo spent most of her time with her computer named Kumausa. The lack of human contact is intentional for numerous reasons, part being her personality, part being the need to keep away from those who would use her mind for nefarious purposes, and partly because her biological mother abandoned her out of jealousy over her intellect. Tsukasa Mikogami managed to improve her outlook on life, however.
Ringo specializes as a scientist, specifically as an engineer, inventor, and nuclear physicist. She has resolved the problem of radioactive waste, discovering how to make it decay almost immediately, and has build nuclear reactors herself.
Despite her careful, calm, and calculated outlook on life, she still has trouble admitting to Tsukasa that she has feelings for him.
