Define a Villain

A world where there are "superpowers," a new race of humans who surpass human abilities, and "guides" who can control their rampage. Betty, a guide, hides her identity and lives in a small town in America. One day, James, a super-powered hero, transfers to Betty's school to find the villain "Dave." Betty avoids James but continues to become involved with him. And to make matters worse, while trying to stop her best friend's rampage of superpowers, she is forced to use her guide abilities... It turns out that her friend is not an ordinary superpower, but a villain. It was Dave! Betty is caught between a villain and a hero, and her life, which she wanted to live normally, begins to spiral.
