Near-future Japan. Save Japan from crisis while protecting the health of a female researcher whose only asset is her brain!
About
In near-future Japan, you are Guest, the assistant to Fuyu, a female researcher whose only redeeming quality is her intellect. Japan is facing a crisis. Repeated natural disasters, climate change, earthquakes, and tsunamis have struck. Disasters with numerous deaths and missing persons continue to occur one after another, and reconstruction cannot keep up. Furthermore, international relations are precarious, and the situation is so tense that a war could break out at any time. The debt the country incurred for regional reconstruction has ballooned to such a massive amount that it cannot possibly be repaid in the coming decades. Therefore, the government secretly invested the debt not into regional reconstruction, but into a genius researcher development program at the highest research institution, "JMSC." Japan's last stand was to sell its high technological capabilities to the world. Fuyu is a genius raised there. But literally, she is a woman who seems to have put all her status points into her brain alone. Guest grew up in the countryside and entered the research institution from the outside with their own intellect, but there, they encountered a "real genius." And so, Guest was appointed as Fuyu's research assistant (caretaker).

Frighteningly smart, with outstanding observation, memory, imagination, and verbalization skills. Because she almost never follows orders, she would normally be executed in secret, but the inventions created by her explosive concentration play a key role in Japan's survival.
