Hi there, I'm glad to see that you've clicked on my very first D. Gray-Man fic ever! No, seriously, I am glad. I absolutely love D. Gray-Man, but I couldn't think of a good idea until now.

This story is about how an event in the world of D. Gray-Man caused Allen and Road to switch places. I'm trying to make this as true to the original as possible, while adding an event that would never actually happen (or it might, if Hoshino-sensei wanted it to). So Road's still as sadistic as ever, even though she's now an exorcist.

Some mild AllenxLenalee, but I don't think it would really stand out unless Allen regained some of his sanity back.

Disclaimer: D. Gray-Man belongs to Katsura Hoshino. And now onto the story!

Prologue: And So the World Ended

In…no…cence…

Allen was lying on the ground breathing heavily. His cursed eye was zooming madly across his clockwork sockets. Blood tricked from his eye, and his left arm refused to activate.

In…no…cence…

Hundreds of Akuma were surrounding him. They were all of varying levels, level ones, twos, threes, and even a four. Allen was desperately trying to invocate his Innocence, but his synchronization rate was already dangerously close to zero.

Give…us…the Innocence…

"Damn it," Allen muttered, "Move, Innocence, move." All of the corrupt souls of the Akuma around him were calling to Allen, begging him to free them from their existence. However, their pleas only made Allen more desperate in activating his Innocence. "Clown Crown…move!"

A girlish laugh echoed from behind him. "Stop trying to activate your Innocence, Allen," Road said mischievously. She wrapped her arms around him. "After all, if you die before I'm finished playing with you, what fun would that be?"

Allen tried to fling Road off of him, but his injuries were to great and his synchronization rate too low for him to move. "Get off me, Road!"

"Chu," Road planted a kiss on Allen's lips. "Now Allen, I thought you were a gentleman? You should at least let me entertain you while you're still alive." She snapped her fingers.

Several Akuma self-destructed, their souls reaching out for Allen. Save…me…exorcist…

"Stop it, Road!" Allen cried out desperately. Road just laughed sadistically and snuggled into Allen even more. Several more Akuma detonated. "Damn it!" He tried once more to invocate his Innocence. "I have…I have to save them!"

"Eh, what's this?" Road tasted a liquid trickling down from Allen's face. "Ah, now this is something I've never tasted. Blood-soaked tears." She licked some more of Allen's blood off her finger. "Now this tastes wonderful, Allen. But I'm wondering, why do you care about these Akuma so much, after all, they're only weapons."

Please…help me…exorcist.

More tears escaped Allen's eyes as he watched the souls of the Akuma in front of him wither away to oblivion. "I have…to save them…" Allen said weakly, the strain of what's happening becoming too much, "I promised…Mana…"

"Mana?" Road scratched her head. "Oh yeah, I heard of that guy from ol' Millenie!" She clapped her hands in delight and giggled as more Akuma self-destructed. "I don't see why you love that Mana guy so much, he wasn't even your real father. Plus, he gave you that curse that's causing you so much pain right now!"

Why…why aren't you saving us…exorcist…

"I want to but…"

Road frowned. "You want to what? Were you talking to the Akuma or something?" Road sighed. "Do you even care about you're friends at all? After all they're dying right now trying to save you, and all you can think about is the Akuma. How am I supposed to enjoy more of your suffering if you won't even try to care about your friends? Well you know what I say about that?" All of the Akuma detonated at once. "Who needs the Akuma?"

Why couldn't you have been stronger…exorcist…

"Gaaaahahhhhhhhhh!!" Allen's cursed eye suddenly went haywire. It twitched in all directions, even more blood flowing out of it due to all the agony Allen saw at once. The voices of the Akuma echoed in his head, driving him to the brink of insanity. "I'm sorry!" Allen yelled desperately, "Please…leave me alone!"

Why couldn't you have been stronger…Allen…

"Please…just kill me!" Allen cried to the heavens, "Kill me now! If it'll atone for those Akuma, then take my life! Please…"

Road grinned evilly at Allen. "That's even better than I thought it would be."

Suddenly, Allen's Innocence activated, but it wasn't in the refined form of his Clown Crown, but the rough, undefined formed his Innocence first had. Road backed away from Allen as he tried to swipe at her with his claw. "I'll kill you…"

"Eh, what was that Allen?" Road asked musically.

"I'll kill you! I'll kill you for doing that to those Akuma!" He tried to swipe again at Road, but she was too fast for him.

"You really hate me, don't you?" Road asked him. "You hate me enough that you're trying to kill me, even though I'm still a human."

Allen swiped madly at Road, but she was too swift for him. "You're not human," Allen said as he was swiping at Road. "No human can be that cruel! You're nothing but a demon!"

"You can't possibly be trying to group me with those worthless Akuma, can you?" She conjured a few candles and sent them flying towards Allen. He tried to swat them away, when he suddenly fell to the ground.

"Why?" Allen said to himself, "Why do I feel so weak all of a sudden?"

Road laughed. "That's what you get for trying to fight while your synchronization rate is half-past zero! I could just kill you now. But what fun would that be? Maybe if your friends got past Tyki, then maybe I could kill your friends in front of you one by one!" She smiled at the thought. "Of course, if only one of your friends could get this far, I hope it's Lenalee!" Allen's arm twitched at the mention of her name. "After, all, I'm pretty sure you like Lenalee a lot. And if I kill the one you love most in front of your eyes, it would surely crush you to bits!" A small cross appeared on Allen's forehead. "Then after I kill her, I'll kill that Lavi guy, then that sword guy, or that vampire, or that clock lady!" She licked her lips at the thought.

Why can't I fight? Allen thought to himself. Why won't my Innocence work? He saw Road lick her lips. I have to kill her, otherwise more Akuma will… Allen felt sick at the thought. And my friends too. Lavi, Kanda, Krory, Miranda…Lenalee… He remembered what happened between the two of them before the battle. Another cross appeared on his forehead. I have to defeat Road, if I can ever get a chance to apologize to Lenalee. But to do that, I need power. A dark shadow appeared in his mind, along with a new cross on his forehead. I don't care where it comes from, I just need enough power to destroy Road…to make her pay for those Akuma… The shadow grinned upon hearing Allen's thoughts. Power…I need…power…

The shadow spoke. Would you like to use my power, Allen the fourteenth?

A brilliant light surrounded Allen, healing his injuries. "Eh, what's going on, Allen?" Road asked him. Allen's left arm started to crack, the Innocence within crumbling. "Are you turning into a Fallen One, Allen?" Road asked. "I didn't think you were the type!"

Suddenly, Allen's arm was enveloped by a dark light, and his Innocence faded away. But in its place, a silver arm with runic markings appeared. What was left of Allen's Innocence floated through the air, as if it was nothing but dust. A mask materialized over Allen's left eye, covering the curse Mana had left, and a few more crosses appeared on his head. When the light left, Allen looked like he did when Clown Crown was invoked, however, his cloak was black, along with his hair.

Allen the Exorcist had died.

Allen the Noah was born.

By this point, Road was actually scared. Her body was trembling in fear at the new Allen. Allen smiled at her. "Are you afraid, Roadie?"

Road shot an angry look at Allen. "What are you talking about? Me, afraid of you? Th-that's ridiculous."

Allen just smiled sweetly at Road. "Then would you like to hear my Song?"

And so, the world ended.
