A child. Almost none of the land below noticed, and to the few that did it was but a shooting star. Falling through the stratosphere and burning up. But it did not burn up completely, no instead she kept on falling, further and further down until impact. The small crater produced made little dent in the landscape. Already ravaged by a beast with nine tails. The name given to the baby, found clinging to life that night, was Sukiyaki Kuro.
Kuro grew up in an orphanage. She didn't have any friends as she liked to keep to herself and read or, when she turned 6 and started attending, study class materials from the academy. She wasn't top of her class, but she wasn't at the bottom ether.
Today she was sat, in a small garden to the side of the orphanage, reading one of her favourite books. A book on the basics of chakra and its control. She found the idea of jutsu fascinating and would read and reread books on the topic whenever she had the opportunity.
While she read, really only glossing over words and passages she already knew, she meditated. First, on the subdued feeling of power beneath her skin. Then, further inward toward her core and chakra network. Finally ending on the substance itself, the raw chakra, split into its two halves. Light and dark spiralling round one another, the mental and physical energies of life.
Kuro fell asleep in that garden, eventually found by a caretaker and taken to her bed.
