## Biography

### Early Life

Nariko Yagyu was born outside of Osaka, Japan as the daughter of one of Earth's leading Vitaria engineers, Kazuhiro Yagyu. She was the only child to her nearly 40-year-old parents after several unsuccessful attempts at having children. As such, Nariko was heavily sheltered by her parents and was diagnosed with having learning disabilities.

At age 2, Nariko and her mother, Mayumi (neé Shimizu) were involved in a deadly car accident caused by a drunk teenager. Both were in critical condition and suffered massive brain damage. Unable to cope with the idea of losing his family, Kazuhiro was determined to find an artificial way to save his wife and daughter that normal Earthly medical practice couldn't. He reached out through his connections to commission 3 interdimensional scientists and doctors to help develop interdimensional ways to "repair" the brain damage. They operate in their brains to convert the damaged portions of the brain with nanocomputers to artificially perform those brain functions. Her mother's failed and she passed, while Nariko's was a success and survived. Her memories were lost and converted into data and stored on a supercomputer in an inaccessible server that only Kazuhiro had access to. As the media caught wind of the news, they hailed Nariko as a miracle child, unknowing of the practices that her father went through to make the miracle happen.

As a result of the operation, Nariko gained superhuman intellect and was able to overcome her learning disabilities. She excelled in school, graduating high school by age 14 and graduated from Kyoto University at age 18. She studied computer science and was quick into making her own patents and receiving a respectable income to help finance her father's projects developing Vitaria-powered gadgets to be used by Jumpers. Due to Kazuhiro's connections in the Jumper Society, Nariko was recruited as a scientist to assist in gadget and weapon development, while fronting as a successful computer engineer, interning at large companies like Sony, SoftBank, and Fujitsu.

When not studying in school, Nariko's biggest hobbies were kendo and karate, saying that one day she would like to become a real life ninja as a child. Her brain allowed her to possess faster reflexes than a normal human, allowing her to excel in these fields as well. Despite all these accomplishments, her brain wasn't able to portray real emotions and Nariko struggling with making long term relationships with people, including Kazuhiro. Nariko is unaware of her artificial brain and rationalized her success by her working hard and being naturally smart at suggestion of her father. From her miracle story as a child and her successful as an academic at such of a young age, she rose in being a prominent cultural figure in Japan often invited to speak at expositions and business conventions to speak about her story.
