No. 6
Summary
The story is set in "No. 6," a future model city in 2013. Raised as a top-ranking elite since the age of 2, a boy named Shion lives in an exclusive area in No. 6. On the night of his 12th birthday, he rescues a boy who calls himself "Nezumi" ("Rat"). Nezumi ran away from the city's Special Security Area. From that moment on, Shion's life is changed forever...












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).
