A global takeover launched Earth into a new age where people live in hedonism, and at the top is the organization that overthrew it all, "COT".

Masao Takeda, a 23-year-old shut-in, happens to meet an escaped victim of COT, a sheltered girl who was frozen in time long before the new age. He takes it upon himself to protect her from the people who plan to use her innocence for their research. How can these two misfits create a life together in a world determined to tear them apart?
