A/N: For awhile I've had this story on the mind, and have written little parts of it over the months, but never done a full chapter due to school. I might edit this chapter depending on my mood and if I feel like it needs to be done. But for now, enjoy the prologue of "Hide and Seek."

There the monster stood, eyes ablaze with fury. His growling increased with each struggle to break free from the chains that held him back.

The man breathed in before opening his mouth.

"Hello, Arthur."

The demon's emerald eyes fixed upon the pale face of his target. A sneer crept along the corners of his lips.

"Hello Francis, what brings you to this place? Come to triumph over my defeat?"

"Non, I want to know what happened to her."

"Oh? I don't know who you're talking about."

"You damn right know who Arthur. The girl you lured away. The girl you toyed with!" The demon gave a cat like grin.

"Ah, that girl; It was only a game of cat and mouse. She choose to be the mouse and scurry throughout the maze, trying to find a way out. Of course she should have known…" Arthur said with a dark chuckle. "A cat always catches its prey."

"N-No…" Francis felt his knees weaken. So it was true, she was gone. "You bastard."

"Why thank you, my sweet. If you miss her so badly, you're welcome to join her." Francis clenched his teeth together.

"What did you do to her?"

The monster in front of him just laughed, his voice filling the dead space throughout the room.

"Again, again. I enjoy the pain in your voice whenever you speak."

The demon looked human enough; but at the same time he wasn't. His skin was as pale as freshly fallen snow, his eyes glowed an ominous green. The smirk plastered across his face was nothing a human could be able to hold.

"Monster." The Frenchman spatted. Arthur frowned.

It's just my nature. This is my soul, tainted with hatred of the others, forced to carry on the burden of other people's past mistakes. All their sins go into me, and I have to bear them; lust, envy, murder. You have no idea what it feels like to feel whatever they felt, their last moan or cry for mercy."

"You have no soul, Arthur." Francis snapped. "You made that known when you came in and slaughtered all those innocent townsfolk, when you came in and took her away from me. You don't feel anything."

The demon's face broke into a sneer. "It makes me feel….alive. Their blood staining my lips and teeth are just something I enjoy. It gives me that…tasty feeling. I have to say, feeding off your emotions and blood was delicious." He licked his lips. "So what's next; are you going to destroy me?"

Francis couldn't believe anyone could be so monstrous, so inhuman. Only a demon could look into the eyes of a young child and take their soul without guilt. The Frenchman felt his teeth grind against each other. As much as he wanted this despicable being destroyed, he couldn't do it, not to him. He didn't deserve death; that was too kind. He wanted to make it hurt. Arthur was going to suffer for his sins. Every single one of them.

Rising up to his feet, he looked the creature in the eye, pure rage from the priest's sapphire eyes firing back at the demon's emerald ones.

"Non, I have something else in mind for you." It was risky, and would cost his body a lot, but what else could he do? Arthur was just going to keep murdering if he let him roam. So many years has he let him do that, it was time it all stopped.

Arthur cocked an eyebrow. "Oh? What is it love; another splash of holy water? Or perhaps it's a stretch on the rack. Face it frog, there's nothing you can do to me. Absoooolutely nothing!~" He said in a sing song voice as Francis neared him. He took a dagger out of his bag. With a grunt, he slashed one of his veins open, letting the blood drip to the floor. He repeated the procedure with the demon, only producing a snarl from it. Both of their blood expanded and tangled around the two in a devilish dance. The Frenchman then went over to the old mirror by the door and brought it closer to Arthur. The demon cackled.

"You've got to be kidding me. This is old magic! You honestly think that this will be able to hold me Francis? I'll break free the moment you die."

"I'm not trying to capture you whole; I'm partly capturing you." The monster narrowed his eyes.

"What do you mean?"

"I know you have a human heart somewhere deep down, Arthur. Maybe you don't show nor use it, but it's there. Do you remember what you used to be before you became what you are today?" Arthur just rolled his eyes in annoyance. This man was going to bore him to death, he was sure of it.

"Weak, just like you."

"No, you were a hardworking man; you had a lover; a home." The Frenchman reached into his cloak and pulled out a locket. "Do you remember this?"

Arthur struggled against the chains as Francis brought the jewelry closer to his face. It was making him strangely uncomfortable. His face paled. "I-I've never seen that thing in my life! Take it away from me!"

"You know you have. I loved you when you were still human; hell, even now I think I still love you."

"Lies! It's all lies!" By now, the demon was becoming unnerved; he was losing his grip on the Frenchman, and he knew it. The tide was turning; he could feel his powers quickly slipping away and him getting weaker by the minute. It was the first time in years that he felt vulnerable to the man. "You hate me! You've said it yourself!"

"I just hate what you've become." Francis said, a sad look passing through his eyes before dropping the locket into the pool of blood circling them. The mirror began to glow green and so did Arthur's eyes.

"W-What is this? What are you doing to me?" he shouted in panic.

"Instead of trapping you wholly in one mirror like you expected me to do; I'm splitting you from your demon half."

"You wouldn't dare." Arthur growled, black wisps of smoke beginning to come from his body. Francis sighed.

"I would, for you. Because I care about you."

"Liar!" By this time the demon was screaming and shouting curses at the Frenchman who just stood and watched as the black mist poured from out the others body and into the mirror in front of him. Finally, it ceased. And where a full grown man once was chained, sat a helpless baby. It looked up at Francis with innocent green eyes.

"Arthur, it was for your own good. Now you'll be able to start another life, and perhaps have a better one." He picked the infant up and left the dungeon, leaving the cursed mirror behind. He would instruct the others what to do with it later, as for now the child needed a home. By performing the spell, he was cursed for eternity to bear the pain and suffering of others who have died at the hand of the demon, including Jeanne, while taking care of the monster responsible for her death. It would be difficult, but in time, maybe….just maybe `he and Arthur could be happy together again.
