The stage of this story is a future world after mankind has been defeated by silicon-based life. It tells the story of "Tianyan", the super artificial intelligence computer left behind before mankind's defeat, to create humanoid weapons in order to take back the earth.
Most people in this era no longer remember the fact that humans were defeated by silicon-based life forms and became livestock raised by the other side, and that the other side had to absorb nutrients called "emotions" from humans in order to maintain their own existence.
Jing, a girl who thinks she has lost her memory but actually has no memory in the first place, is the ultimate humanoid weapon created by "Tianyan" based on the genes of silicon-based life and integrated with the strongest human technology. However, because "Tianyan" cannot analyze something called "emotion", the weapons produced inherently lack the most important source of energy. Therefore, Jing was placed in the human world in a blank state by "Tianyan", and thus embarked on a journey to find a lover to gain "emotion".
Motto: Life is short, fall in love, girl!
