Mori wanted to be a parents. He had everything else in his life set up, so why not become a foster parent? He passed the check easily, as he was a doctor with no criminal record in the eyes of the law.
His only preference was for them was that they be a girl. He didn't mind any age.
What he didn't expect was to be asked if he wanted to take a little girl, who was formally in the sex trade, who officially came from Kadykchan in Siberia.
Kadykchan was a town built by prisoners during World War II in the remote Kolyma region, known for the "Road of Bones." It was a coal-mining town populated by those sent to work in forced labor camps while located in a remote mountainous area of the Far East.
After a mine explosion, the government abandoned it in the late 1990s and it's population was left to its own devices in isolation.
How the girl ended up in the Japanese sex trade was unknown but she didn't speak anything other than a distinct dialect of Russian and hadn't seen any kind of modern technology, or even experienced a summer before.
He accepted. Of course he did. He couldn't pass up this girl— nobody else would want to take her. He was prepared for anything considering that she was raised by former forceful camp workers in complete isolation.
Her first interaction with civilization was in Japan— a place that shared no similarities to her home in Siberia and didn't even have the same race.
She didn't respond to any name and her real one was completely unknown as of yet. If Mori could get her to respond to any name, that would become her official name pretty much immediately. She also didn't have any record of having any vaccinations, so Mori would need to make sure that she got all of them, including the ones that were administered to small babies. She had been given the first few so far, but she would need to be given more later.
During the first administrations, she needed to be held down because she bit, scratched and kicked. She likely hadn't been raised with needles around.
