Black Jack character. A very small little girl with a brown hair bob cut who works as Black Jack's assistant and nurse.
She was created by him using a parasitic teratoma (a type of tumor composed of human tissue from different organs that originate from a twin that never fully developed) that was inside an 18-year old girl. Black Jack gave it an artificial body of its own (so she is technically a type of cyborg). Her twin sister rejected Pinoko, so she lives now with Black Jack as a sidekick, nurse and daughter figure to him.
