In every modern society, you have youth turning to delinquency. This applies even to a society where monsters coexist with humans.

Our heroine is one such delinquent: a gal/gyaru that sleeps around for money. She’s also an oni: strong, sturdy and horny (literally and figuratively). That means that when her gym teacher tries to correct her behavior, he gets more than he bargained for.
