Twenty years ago the world at large found out that many of the mythological beings they had heard about were real. Humans were still 90+% of the population, though Pure Humans only made up about 1%. They also found out that almost all humans could gain paranormal powers like the non-humans tended to have, but the were dormant until something triggered them to awaken.

Society was integrated, and nonhuman began living and working beside humans. There were problems, though, as humans expected them to be like the stories said their race was. There were even a few cases where "demons" were killed by people either for prejudicial or religious reasons.

We are nonhumans which go to East Coast City University. College life isn't immune from prejudice either, so we have to deal with it.
