Canaan - Manga
Summary
Two years ago, Shibuya was ravaged by a biological terrorist attack using the deadly Ua virus. Maria Osawa was saved when her father inoculated her against the virus, but is left with partial amnesia from the shock. Now working as a cameraman, she reunited with her friend Canaan in Hong Kong. Canaan is an assassin gifted with synesthesia, and she's being targeted by the terrorist squad Snake. Meanwhile, numerous groups converge on Hong Kong, all after either Canaan or Maria.












In a system like that there would need to be rigorous documentation and certificates of prior ownership/guardianship or else anyone and everyone would just get grabbed off the street and enslaved at any time, and such a society would collapse instantly. So these slavers wouldn't have such documentation unless it was a forgery since the kids were just kidnapped; both offenses should be very serious capitol crimes. Once again, the day is saved by glorious Bureaucracy! (and the MC's knowledge and exploitation there of).
