Reisuke believes there may be a terribly powerful demon inside him.

Everyone undergoes an exorcism when they come of age, but he's afraid it might be dangerous. What if his demon is too strong for the Exorcist to handle? It could go on a ruinous rampage, scorching the countryside for miles around like the Wrath demon that was removed from his twin sister. It destroyed everything he knew.

It incinerated everyone he loved.

The trouble is, if he's ever going to have the power to avenge their deaths, then he'll need access to his hidden class. He'll need access to the System the demons keep us from seeing. He'll need to accept the risks of letting his demon out into the world.

And then it'll be time to start kicking ass all the way to Hell and back.

We All Have Demons is a Demon Tamer/Evolution story. Kinda like a Dark Fantasy Pokemon but funny sometimes, I hope.
