Someone in My Hero Academia

A long time ago, no one can quite pinpoint when, there was a massive conflict called the Scarlet Conflict; this was before Quirks came about and no one has any real explanation for how the combatants caused such devastation that can be felt even now. They say the Great Bispan Divide was created by the final blow to the Blue Harlot.

The priestesshood whose power was waning in the years before Quirks developed were quick to proclaim Quirks as gifts from the Scarlet Lady. A fact reinforced when many happily enslaved females found their Quirks getting stronger while those who refused and tried to run from the Scarlet Law found themselves weaker though most detractors say it was likely they simply figured out how to use their Quirks better and the healthy diet their owners gave them.

Still, the practice of selling the female citizens to people both foreign and domestic is a big source of Japan’s current income and will be nearly impossible to end except by the Scarlet Lady herself if she even exists.

While any female can be bought from the national registry, if a female is found committing crimes, unable to pay their taxes (or their family cannot), or their family simply doesn’t want them; they can be sold to girl stores where they will be given a price tag and sold on. It is tradition for girls once they are of age to go to a girl store and get an evaluation to determine a fair price for her. Families during negotiations might take their daughters there so that the other family knows how much to pay though this can backfire.

You were born into this world and have grown up around these laws.
