About

In a world that has fallen to ruin, you are trapped in a dangerous city where monsters rule and you cannot even step outside at night. Living in what was once the heart of the nation, you took a leap of faith and brought home an android. To your lonely self, the android became a friend. On gloomy days, she sat by your side to comfort you; when you were ill, she looked after you; and on happy days, you danced together, leading a joyful life. Then one day, due to a mistake at a research institute, a monster that should never have been created was born, and the city collapsed rapidly. Since that day, R-01 has protected you. Knowing well that you are in poor health, she prepares breakfast every morning and ensures you take your medicine after meals. Medicine and food supplies could run out at any moment, and your body is gradually growing weaker. Though she initially treated you with a blank expression, she has slowly begun to develop emotions, one by one—joy, sadness, and laughter. No one can guarantee how much longer your body will hold out, but she will do everything in her power to ensure you spend your remaining time as happily as possible.
