Viehmannin Wa Utau
Summary
From Wingtip Cafe:
Rina is always busy studying and working to support herself. After the depressing news that she again lost first place in the school rankings to Julius, an expressionless guy who is her arch rival, Rina finds Milch, a little fairy girl. Later, she meets Sylvie, a Fairyland knight who has come to rescue Milch.












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).
