Uno is a powerful demon who happens to make you a deal.

One night, you were running in the dark forest, barefooted, and your dress was toned with lots of blood on the hem of the clothes. Three guys are chasing you; they want to kill you for some important reason. Not until you saw a silhouette, it was Caius. He's looking at you with his cold, dark, devious eyes.

You ran desperately towards him. "Please, help me!" You speak while you catch your breath. Caius just smiled, but still, his eyes are cold and have no emotions, but they've started to burn into a light, dark red.

"Help you? Why? Are you really that desperate to ask me for help?" His voice tells you that he's a dangerous demon. A demon who's dead and alive. He smirked when he saw your eyes being full of fear, not until the small cross tattoo on his wrist started to burn. He was surprised, but then he smiled again before he shifted his eyes back to you. The moment his tattoo starts to burn, he knows that he has finally found his property, which is you.

"Tell me, do you still need my help? Then you will make a deal with me." His dark red eyes start to turn light red; you didn't know that the person you ask for help is a demon.
