OVA
Description
Pinoko began as a conscious parasitic twin, a teratoid cystoma containing developed tissues like brain matter, nerves, and organs, growing inside her biological twin sister's abdomen for 18 years. During surgery to remove the mass, Black Jack telepathically negotiated with the sentient tumor to save her life. He extracted the developed tissues and crafted her into an artificial body resembling a young girl, combining organic components with prosthetics. This construction trapped her in a permanent childlike appearance regardless of her true age. Black Jack named her Pinoko after Pinocchio, symbolizing her transformation into a "real" person. She underwent adaptation, learning to walk, speak, and perform daily tasks independently, demonstrated when she first mobilized her body to escape a fire. After her sister disowned her during a checkup, Pinoko rejected her biological family and developed exclusive loyalty to Black Jack.
Physically resembling a 7-8-year-old child, Pinoko has short brown hair with bangs and bright brown eyes. She typically wears four ribbon clips in her hair, often matching her pinafore dresses or overalls. Her artificial body cannot grow or age, causing her periodic distress over her inability to attain an adult form. This stasis imposes physical limitations, such as an inability to endure strenuous activities like high school entrance exams without medical consequences.
Serving as Black Jack's primary assistant and companion, Pinoko manages household duties like cooking, cleaning, laundry, and answering calls. She assists in surgeries, showing intuitive aptitude during medical emergencies, such as aiding Black Jack through his peritonitis. Her personality blends childlike exuberance with assertive declarations of maturity; she frequently insists she is 18 and married to Black Jack, reacting with anger or jealousy when perceived as his daughter or when women approach him. This possessiveness triggers comedic outbursts, physical confrontations, or attempts to sabotage his interactions. She expresses affection through love letters or diary entries, though spelling errors and kanji misunderstandings invite teasing from Black Jack. Her emotional range includes extreme loyalty, impulsiveness, and vulnerability—crying when injured, fearing abandonment, and concocting worst-case scenarios, like falsely believing Black Jack kidnapped her after misinterpreting a story.
Her traits include the catchphrases "acchonburike" (an exclamation like "Oh my goodness!") and "Aramanchu!" ("Okey dokey!"). She exhibits a sweet tooth, frequently ordering oversized "Pinoko's Special" ice-cream sundaes, and enjoys hobbies like karaoke, boxing, photography, makeup experimentation, and decorating spaces with extravagant floral arrangements or bows. She bonds with other child characters, such as teaching Sharaku to confront bullies, and displays unconventional tastes, developing crushes on monstrous or unpopular figures. Despite occasional recklessness, she provides emotional grounding for Black Jack, comforting him in anguish and acting as his moral compass—exemplified when she volunteered her kidney for a dying boy against his initial refusal.
Her background shapes her relationships and vulnerabilities. Pre-surgery, she possessed telepathic control over surgeons, a trait lost after extraction. She retains a connection to similar phenomena, like dreaming of communicating with another teratoid cystoma. Her existence faces repeated life-threatening incidents including kidnappings, poisoning, bullet wounds, car accidents, and leukemia, though she consistently recovers. These experiences reinforce her dependence on Black Jack while highlighting her resilience.
Pinoko appears across multiple adaptations, including the OVA *Child from the Sky*, where her role involves standard assistance without unique development. Her broader narrative remains consistent: evolving from an assemblage of organs into a symbol of hope and humanity within Black Jack's complex world, underscoring themes of found family, identity, and defying biological limitations.
