Originally designed to alleviate the burden of caring for the elderly, the Z Project aimed to introduce a machine capable of independent elderly care. Initially hailed as a promising solution, it garnered support from the younger population. However, when the elderly Mr. Takazawa became the initial subject for the Z-001 machine, Haruko raised concerns about the hospital's methods and the ethical implications of this technology. As Haruko challenges not only the hospital but also societal norms, she stumbles upon a startling revelation—the machine operates using a biochip, evolving into a sentient entity of its own.
