Ringo Ohoshi

Ringo Ohoshi is a once-in-a-millennium intellect whose scientific breakthroughs—including a self-developed compact nuclear reactor—place her centuries ahead of her contemporaries. Profoundly introverted and uncomfortable in social settings, she spends most of her time aboard a space station of her own construction, relying on her custom AI companion 'Kumausagi' to handle everyday life. After crossing into another world, she channels her anachronistic expertise to engineer advanced facilities and formidable weaponry, cementing her role as the team's irreplaceable technological backbone.
