At the "Ijinzaka Clinic" day service, a revolutionary treatment devised by Director Urushihara is secretly spreading among the elderly. Aiming for the ultimate cost-effective care, the amputation of "Disusebody" (limbs with no hope of recovery) has reportedly led to unexpected positive side effects, such as patients feeling "lighter in body and mind" or "developing a gentler personality." Yagura, an editor who hears these rumors, senses a potential revolution in geriatric medicine and proposes a book deal to Urushihara. However, an internal whistleblower leak about the daycare center soon surfaces in a weekly magazine. Following a shocking incident at a patient's home, everything begins to spiral into darkness.
