My super hero, The super villain

When you need a hero, you'd never expect a villain to come to your rescue. The villain is a bad guy. The worse there is. That's why they call them villains, and not heros. Because they do bad things. So why is a certain villain helping a girl and her little brother out? Ayana and her little brother Jamie get saved by the so called "super villain." And soon said super villain begins popping up around Ayana when she least expects it. At her school, job, even her bedroom! And other people she's never met before soon join the mix of new faces.

So now she wants to know. Why is a super villain helping her out, protecting her? And she intends to find out.

And another thought.

Why is he a villain? Powers don't just come from thin air. Or...do they?
