Lavi and Allen met each other in Komui's office, summoned for a mission briefing. It was early in the morning, even for them. "So, what kind of mission only needs us two?" Lavi asked.
Allen shrugged.
"Dunno. Considering that Akuma are on the rise, I thought the Chief would make us a team of three."
The two boys sat on the couch, staring around the massive office. Timcanpy flitted around for a while, then landed on Allen's shoulder to nap.
"Ah. Good morning, you two. Thanks for coming on such short notice."
Komui had entered from an adjacent door, carrying a rather sizable stack of papers. It didn't take much for the exorcists to tell that the Chief hadn't slept recently.
"Hey, Chief. So, what have you got in store for us?" Lavi replied casually.
Komui laughed quietly.
"Chipper as always, Lavi. As for the mission..."
He rummaged through the papers for a moment, then handed Allen and Lavi two folders.
"Well, we have reason to believe that an Accommodator is hiding out in the forests of Sweden. They are pretty elusive, so Finders haven't been able to get much information other than their location."
Allen's eyebrows rose, and he shared a curious look with his red haired friend.
"Huh. They must've gotten some pretty good advice on avoiding the public eye."
"Yeah, no kidding."
"Well, that's about it. I'll call you through Timcanpy if anything else comes to light. Good luck!"

Allen and Lavi gathered their respectably meager luggage and reunited on a boat to take them to the train station. While half-listening to Lavi ramble on about his complaints with Bookman, Allen had time to ponder just who the Accommodator might be.
"You zoned out, didn't you, Al?"
The Crown Clown's gaze refocused on the amused look in the bookman's eye.
"Sorry. I'm just really curious who this person is, that's all. It's been so long since we actually had a lead on a possible Accommodator."
Lavi smirked.
"I'll bet you that they're a cute girl."
Allen rolled his eyes.
"You always say that about every mission."
Lavi scoffed in mock offense.
"I do not!"
The silver haired exorcist grinned.
"Sure you don't."
Eventually, Lavi let his friend nod off for a nap.
Meanwhile, he lay on the bench and held a book over his face, attempting to read it.
Allen found his dreams to be particularly uneventful . Not even the creepy shadow of the Fourteenth had come to taunt him with its presence.
All of a sudden, he saw the silhouette of a young girl. Her back was to him, and he could see strange tattoos in the shape of wings on her shoulder blades. She was singing; or so it appeared. He reached out to touch her, but she moved away, and continued to sing.
Her voice sounded so... familiar. Allen knew he'd heard it somewhere before.
All of a sudden, he saw a younger version of himself, standing timidly by someone's hospital bed. Cross Marian was there too, and had sat on the edge of the bed, his hand on the dark haired head of the bed's occupant.
A child.
She faced away from them, her knees drawn up to her chest.
"Someone with a voice as beautiful as yours shouldn't have to live in fear," Cross said, a kind smile on his face.
The younger Allen rolled his eyes. Why does Master have to flirt with every girl he sees? He thought to himself.
Suddenly, the girl's head rose, staring at Allen's master hopefully.
But before he saw her face, Allen awoke to Lavi shaking his shoulder.
"Al! Wake up, I think we've got company!"
Sure enough, Allen felt his cursed eye being activated. He glanced up at the ceiling-or rather, through it-and spotted four Akuma surrounding their train car. Passengers near them were chattering in surprise, fear, and awe, mesmerized by the peculiar creatures outside. Lavi opened their window and swung out of it, vaulting himself onto the roof of the train. Allen followed suit, Crown Clown already cloaking him with a shimmering coat of light.
The two exorcists braced themselves on their acquired terrain, which, unfortunately, was still moving. The wind roared around them, making their coattails flap around wildly.
"There's a Level Three, a couple Level Twos, and three Level Ones," Allen counted as he scanned the area.
Lavi had drawn out his hammer, and had slung it over his shoulder.
"How the hell are we supposed to fight these things without falling off the train?!" He exclaimed.
Allen paused for a moment, his eyes frantically searching for something.
"I can use Clown Belt to let us get in the air, and still remain tethered onto the train. I think that pipe over there should be strong enough," he shouted in reply.
Lavi grinned.
"Alright! Sounds like a plan, shortstack!"
Allen glared at the junior bookman.
"Don't you start with that!"
But before they could move, everything seemed to freeze in place.
The train's movement over the rails slowed, and then ceased entirely.
Someone must have told the conductor that the exorcists were on the roof.
At any rate, it would make their battle against the Akuma easier.
A light tap resonated on the train's metal roof, like the sound of a footfall.
A slight figure stood before them, masked with a ratty cloak. They seemed to be looking at Allen.
Allen saw a tear fall down their cheek.
And at that same moment, the Level Three pounced upon the girl.
"NO!" Allen exclaimed.
He reached out, trying to stop the Akuma's advance, but found something that stopped him in his tracks.
The girl was not there.
Not in the way that suggested her demise; it was more that she had completely disappeared.
He heard a loud whistle from above.
Allen tilted his head skyward to find the girl suspended in thin air.
No, that wasn't quite right.
He squinted. Twin masses of light had formed behind the girl. They glittered in the sun like polished emeralds.
"Al, am I seeing things, or is that kid flying?!" Lavi exclaimed. Allen took a second look and confirmed that the lights were indeed wings.
"I guess we found our Accommodator," he replied.
The other Akumas had joined their superior to swarm around the girl like ugly disfigured bees.
"Damn! They've cornered her!" Lavi cursed.
"With the heavens as my witness and the gods as my guides, I invoke thee: Form, Sphere of Solitude!" She declared.
The boys watched in bewilderment as the Akuma were thrown back by a massive shockwave of energy that had emanated from the stranger. A greenish gold sphere had engulfed her, pulsating with power that Allen could sense as clear as day.
He knew this power.
Furthermore, he knew its owner.
"Grace," he whispered in astonishment.
Lavi glanced at his friend, unable to catch the word that Allen had uttered.
"What'd you say?" He asked.
"So she's still alive, even after all this time," Allen smiled in relief, ignoring the Bookman's question.
"Hello, earth to Al, this is Lavi who is completely confused," Lavi said, waving his hand in front of the Clown's face.
Allen blinked, shaken from his reverie. He turned to Lavi, prepared to give a reply.
Just then the girl snarled with anger.
The Akuma were attacking her protective sphere with immense force.
"I didn't think mindless machines could be such pests!" She shouted.
The two boys shared a stunned look, shocked by the malice in her voice. The strange girl suddenly released a large burst of power from her bubble shield, one that tossed the Akumas back a couple feet or so. She then closed her eyes and clasped her hands together, as if praying.
Her voice resonated through the air with an almost surreal melody. It was like a hymn; but at the same time, so very different.
The Akuma had halted in their attacks. From their position, Lavi and Allen thought that the Akumas seemed to be in a trance.
But Allen knew the truth of the matter.
Golden cracks appeared in their bodies, ones that continued to grow as the girl's song continued.
The last vocals of her song rang through the air with a reverberating finality. The Akuma simultaneously exploded, evaporating into dust that was carried away with the returning wind. The sphere vanished, and the girl hesitantly landed upon the roof of the train.
Allen stared at her, and she was looking right back at him.
"Master told me that he didn't know where you'd gone. That you were most likely dead," Allen said.
"Is it...really you? After all these years?"
The girl reached up to the hood of her cloak and slowly removed it from her head. Her short, choppy black hair whipped around in the wind. Her green eyes swam with tears as a small smile rested upon her lips.
"Who else would I be?"
Allen chuckled, grinning at the girl with more happiness than Lavi had seen in his friend for a very long time.
"Well, if you are the Grace I remember, then where's my hug?"
Grace beamed at him tearfully and ran into Allen's awaiting arms, laughing merrily as he danced around, holding her up by the waist. Lavi watched them, smiling amusedly.
"Well, not that I don't find this reunion incredibly touching and all, but we should probably get back on the train. Y'know, keep the passengers from freaking out even more." The two looked at him. Grace parted from the hug, listening carefully.
"There's another train going back the way you two came. It's a couple miles ahead of the one we're standing on, so if we stay on this roof..."
A train whistle blew in the distance, growing nearer.
"Did you gentlemen bring any luggage?" Grace asked.
"Yes, it should be in our car," Allen told her. She nodded, and summoned her wings of light. "Okay. I'll grab it. Holler if you see the train." Lavi jabbed a finger at Allen.
"Al, I think some explanations are in order, don't you?"
The silver haired boy held up his hands.
"Right, right. But I don't think I'm the best person to ask."
The girl returned, toting their bags.
"I may or may not have had to charm your Finder. He'll figure it out sooner or later. At any rate," she handed them their belongings, "we should be getting back. Now that you've found me, I guess I don't have a choice but to join you."

As they sat down in their new train compartment, Lavi noticed that the girl seemed to gravitate more towards Allen; which was understandable, but all the more perplexing.
"Sorry if I seemed to be ignoring you earlier. I didn't mean anything by it." She tucked a lock of hair behind her ear.
"N-no worries. My name is Grace Blüdhaven. I was also General Cross Marian's apprentice."
The Bookman smiled.
"And I'm Lavi, but most of the higher-ups just call me Junior. By the way, what did you mean when you said you had to charm the Finder?" He asked.
She smiled shyly.
"To answer that, I should probably explain just what my power is. And seeing as you are a Bookman, I suppose I do not need to tell you take notes."
Lavi's eyebrow rose.
He hadn't told her that he was a Bookman.
So how did she know?
"The formal name that my Innocence goes by is the Lyricist of God. That being said, I guess it's pretty obvious where it comes from."
She deftly touched the area over her throat for emphasis.
"My voice in itself is a weapon. Anything that must be spoken has the power to become a tool I can use."
"Huh. So that's how you defeated the Akuma, right? With a song?"
She nodded.
"My power can work on both humans and Akuma. The same can be said for the Noah Clan. To answer your question, let's just say I can be very persuasive."
Lavi chuckled.
"I take it you don't reveal all of your secrets?"
"Believe me, Lavi, there are some things about Grace even I don't know."
From there, the three exorcists passed the time chatting, with the occasional break for a snack (or, in Allen's case, a feast).
It was nightfall when they approached the boat that would take them into the depths of the Black Order.
A Finder was waiting for them, and stepped aside to allow the exorcists to climb aboard. Grace held up a hand.
"You guys go on. I'm not a fan of small spaces."
Her wings illuminated the darkening sky, and she hovered inches from the wooden dock.
She fluttered past a rather bewildered Lavi, and the completely baffled Finder. Allen smiled at her warmly. They watched her as she flew into the tunnel and out of sight.

Grace slowed down once she'd gained a satisfying distance from the boat. She sighed, staring at the ball of light in her hand that she'd summoned to illuminate the pitch black tunnel.
"I should be happy. Allen's alive, and I get to talk to him again."
Her hand clenched, and the light dimmed.
"And yet, why do I feel like I don't know him anymore?" She whispered, gnawing on her quivering lip.
Suddenly, she spotted a figure on the dock up ahead. At first glance, they didn't look like much, just some dark haired person with a sword. But, as she came closer, Grace could tell that they were clearly a young man, and a sour-faced one at that. He wore a uniform very much like the ones Allen and Lavi had.
He hadn't appeared to have noticed her yet. She cocked her head, inspecting him curiously.
He had sharp, bright blue eyes, fair skin, and features that she distinctly recognized as Asian.
What a peculiar guy, she thought to herself.
She tried to remember if Allen had mentioned anything about such an individual during their train ride. There was an exorcist girl named Lenalee, and one named Miranda, and a young boy named Timothy. In addition to those three there was a blind man named Noise Marie, and a vampiric Count named Arystar Krory.
So he must be...
Grace swooped down to land on the dock quietly.
"Are you waiting for someone?"
And the next thing she knew, there was a wickedly sharp katana flirting with the side of Grace's neck.
Slightly ruffled, Grace observed her possible executioner. His eyes were colder now, scowl set deep on his mouth.
"You have five seconds to explain who the hell you are and how you got in here, kid, or else your body's gonna lose a head."
She blinked at him owlishly.
Yikes. And I thought I was violent.
"Really? That's all the time I get? And here I thought my death would be excruciatingly drawn out. Such a shame."
He clearly hadn't been expecting that.
Her eyes glowed briefly in the darkness.
"Sheathe your sword and stand down."
As if on puppet strings, Kanda did exactly that.
Grace's eyes returned to normal as she struggled to contain her relief.
"Ah, jeez, Yuu, are you picking on the new girl already?" Lavi called from the newly appeared boat.
Kanda, shaken from his reverie, sharply spun on his heel.
"Shut your mouth, stupid rabbit!" He spat venomously.
Allen climbed out of the boat, throwing a reproachful glare at Kanda before turning to Grace.
"He didn't hurt you, did he, Grace?"
She shrugged.
"Does threatening to decapitate me count?"
Allen growled, facing Kanda once more.
"Is this how it is with you now, ba-Kanda?! You threaten to kill young ladies too?"
Kanda's hand returned to the handle of his sword as he cursed Allen's name with a couple of choice expletives. Grace stepped between them.
"Allen, let him go. Granted, I didn't exactly announce my presence to the world. I caught him off guard, and he reacted. That's all. Right?"
Kanda, obviously miffed at being rendered mute by a girl not even half his size again, rolled his eyes.
Grace took what she could get.
"Let's try this again. Hi everyone, my name is Grace, and I'm an exorcist. It is nice to meet you...?"
He eyed her suspiciously.
"Whatever."
She watched as he walked away, slightly perplexed.
"Well that was... interesting," Grace said after awhile.
"Interesting? I've never seen anyone stand their ground against Yu before," Lavi mused.
"He really doesn't scare you?"
Grace averted her gaze.
"I've met worse people."
Allen placed a gloved hand on her shoulder, his eyes soft with worry. Lavi's eyebrow rose at the exchange, but he chose to remain silent.
"We should introduce you to the Chief. It's getting late, and we'd better catch him while he's still somewhat awake," Allen said.
Grace nodded mutely, and allowed Allen to guide her through the labyrinthian halls of the Black Order. Lavi trailed behind them, observing the girl curiously.
She did remind him of the Crown Clown, polite and cheerful in her own right.
And yet, he could sense a bitterness within her, a deep, heavyset internal turmoil.
Her eyes were the brightest of greens, her smiles soft and shy, her laughter quiet and pleasant. She was shorter than Allen, a feat he hadn't imagined possible until now.
He began to notice how often Grace fiddled with something, whether it was a lock of her short ebony hair or the hem of her skirt. It puzzled him how, even as close as she seemed to Allen, she was still anxious to be near him.
From what he could gather, Grace had been a childhood friend of Allen's; not to mention the fact that she had also trained under Cross Marian.
This in being, why didn't anyone know about her?
Granted, General Cross was an elusive man (to say the least).
Shouldn't Allen, as long as Lavi had known him, have mentioned Grace by now? A brief recollection? A bout of nostalgia?
Too many questions rattled Lavi's mind. He'd have to get a second opinion.
Thus, Lavi ducked into the approaching hallway and out of sight, set on finding the old panda most called Bookman.
