AN: ok this is my first fanfic! Please no flames! In addition, this has slight spoilers for the later chapters in the DGM manga. This story takes place after Timothy but before Alma! So if you haven't read that far don't read this story! Another thing Allen will NOT be hiding his arm! I figure since he now has friends/family that are ready and willing to kick the ass of anyone who dares make fun of him he will be more secure in how he looks! The most he will wear is a glove on that hand. Cross will also make a brief appearance and will still have Judgment. Anyways that's all oh! In addition, there will not be any pairings!

Disclaimer: I do not own Harry Potter or D-Gray Man!

Prologue

There was an old man with a long silver beard and half-moon glasses walking down a deserted street when a scream suddenly shattered the silence. The old man who was known by many as Dumbledore ran to where he heard the scream and came upon a gruesome sight. There was ash and empty torn up clothes strewn all over the ground and a young women cowering in a corner trying to make herself small while some grotesque thing floated above her. It was a great balloon thing with a clown face with black tear marks trailing down its face. It had cannon-like guns pointed at the women and it seemed to radiate malicious intent.

"Stop!" Dumbledore commanded in a strong voice, a pale wand coming from thin air to point at the monster. The thing turned in mid-air to point its guns at the wizard. However, before anything could happen another voice interrupted in a dry amused tone.

"That stick won't help you, old man," Dumbledore turned to look at the newcomer who was leaning against the wall of the alleyway. The stranger had a long red hair and half of a bone white mask on the right side of his face. He wore a long black coat with gold trim and an intricate rose cross on the left breast side, black pants, and black knee high boots. He also held a silver and gold gun in his right hand. A woman with a butterfly mask and a coffin with gold chains wrapped around it stood at his side.

"That thing is an Akuma and can only be killed with a substance called Innocence. Magic is useless against it. The only thing that will help is if you created a barrier around yourself and the girl." With that he cocked, aimed, and fired at the monster all with blinding speed. The bullet pierced the metal flesh of the Akuma and the monster blew up. The stranger walked up to the girl and asked if she was all right.

"M-my date h-he t-turned to a-ash!" she sobbed.

The red headed stranger sighed and looked at Dumbledore. "Do you think you can erase her memories of what happened tonight?" he asked his voice low so the girl wouldn't hear. Dumbledore didn't answer he just walked up to the girl and murmured the spell to make her forget and to fall asleep. "We should also find a way to get her home. She can't stay out here all night." The red head continued.

Dumbledore nodded and called out "Dobby!" with a sharp crack a creature materialized out of thin air. The creature was small, with huge bat like ears, and golf ball sized green eyes, and mish-matched clothes.

"Headmaster called Dobby," the creature named Dobby squeaked. "What can Dobby do for Headmaster?"

"Dobby, find out where this woman lives and take her there." Dobby looked down at the unconscious form of the girl.

Dobby nodded so hard his ears flapped and said, "Of course, sir! Dobby would do anything for Headmaster." With that, he took the girl's arm and with another sharp crack disappeared with the girl.

With that taken cared of he turned to the stranger who had watched everything with slight amusement. "So," Dumbledore said mildly. "Do you mind telling me what happened tonight?" The red head nodded and held out his left hand for a handshake.

"My name is Marian Cross, but you can just call me Cross. And if you take us somewhere more secure I will tell you everything you need to know."

Dumbledore took the offered hand and replied. "My name is Albus Dumbledore, and if you would hold on to my arm I will take us someplace more private." Cross nodded and took the wizard's arm. With a pop and Cross feeling like he was being stuffed into a rubber tube they appeared in a circular office with talking portraits hanging on the wall. Dumbledore sat down behind the desk and gestured for his guest to sit down on one of the two chairs in front of the desk before folding his hands together.

Cross sat down with a tired sigh and looked at the old wizard sitting across from him. "So," he began. "What do you know about Exorcists?"
