On a remote island, the residents are afflicted with a rare illness known as "Pinocchio" that causes their limbs to decay, eventually leading to their demise. However, there are remedies such as prosthetic limbs or unique, antibody-infused replacements. These donors, nicknamed "Doners," are incredibly rare, with only one in every ten thousand individuals possessing them. One life-changing day, Dorothy, a Doner herself, traded her invaluable right eye for an abandoned male Plastica (a robot assistant). This transaction kickstarted a one-of-a-kind story, featuring an unconventional owner and her peculiar Plastica.
