The Akuma of Ikebukuro

(Amaimon) / Durarara crossover ("Fan fiction")

Chapter 1

A/N: This is based after Amaimon's last battle with Rin. Also, right before Mikado has agreed to lead the Blue Squares.

A/N: I'm working on fixing some of the grammar currently.

I'm so sorry it took me so long, but I finally fixed the chapter formatting. I know there are probably some out there who didn't add my story because the chapters being smashed together made it confusing, so I'm hoping this will make it easier to read. I am pretty proud of this story since this is technically the story I wrote that got me really into fanfiction. I took a lot of time with this one, so I hope you all like it.

I think I've said it before, but the reason it was so messed up before was because I was new to fanfiction at the time I first posted this story and didn't know how to post individual chapters. The reason being I originally wrote this whole story in one file. It took me a while to figure out how I would be able to fix this story's formatting. The plot that I already wrote will remain the same. However, it will probably be easier for me to edit the story such as for grammatical reasons or if anything in the story was confusing. There will probably be more author's notes as well. Please feel free to give me feedback.

I'm not sure if I should put any warnings or things such as possible pairings.

I hope this makes this story easier to follow. R and R .

Amaimon was skipping through the town of Ikebukuro, cackling like an excited child.

This city was so interesting. He'd never thought anywhere in Assiah would be able to cure his boredom so much. He was pleased that he chose this town to rest up before challenging Rin again. After the rumors he'd heard regarding the supernatural incidences in the town, Amaimon had the feeling he'd get plenty of practice in before he'd meet up with Rin. Not to mention how many characters here would be fun to play with.

Amaimon smiled to himself. He had left without telling Mephisto what he was up to. This way his older brother wouldn't ruin his fun. There were so many different unusual places to go to in this city. Amaimon loved it! Amaimon stopped in front of a place with the name, "Russia Sushi". Well that's an unusual name for a restaurant. A large black man stood in front of the restaurant and smiled at him.

"Hello there. You try Russia Sushi?" The man had a very thick Russian accent. This man looked like he could be a trained assassin, but gave off the persona of an innocent peaceful man. Along with that, he almost seemed to be wearing some kind of martial arts attire. This in itself seemed odd yet interesting to Amaimon. Amaimon gave the man his usual blank expression, and cocked his head.

Well, brother did always say the best way to experience a place is by trying their food. Without saying anything to the man, Amaimon walked into the restaurant. He took a seat at the sushi bar, flipping the ends of his coat to go over the back of his seat. Amaimon swung his feet back and forth while seated. The black man from earlier came inside and handed him a menu. Amaimon skimmed the menu briefly. He didn't recognize any of these foods. Plus, he was very ancy from anticipating sweets.

"Do you have anything sweet on your menu?"

"Well, we have sweet and sour sushi. That's as close as we get."

Amaimon pouted to himself. "I suppose I'll have that."

The man took Amaimon's menu and left for the kitchen. Amaimon began to bite on his thumb claw. It really was such a shame when he couldn't get sweets when he wanted to.

"Say there, you're new around here, aren't you?"

With his thumb claw still in his mouth, Amaimon glanced over at the man he hadn't noticed next to him before. He was pale, tall, skinny, and wearing a black coat with white fur trip. His hair was raven black and almost in his face. Yet, the way his hair lay like that didn't seem careless, but more like he wanted his hair there. He looked like he could be in his twenties. Amaimon just stared at the man for a moment.

"Yeah." He responded, although it was muffled from his claw being in his mouth.

"I figured, because I know of everyone in this town and I've never seen you here before."

Amaimon didn't say anything.

"My name is Izaya Orihara. I'm the information broker of this town. If someone needs to know something they come to me." Izaya bowed.

Amaimon just stared at him. Why is he doing that?

"And, what might your name be?"

This dude was seriously annoying Amaimon. Why is this human taking an interest in me? Amaimon didn't like not figuring things out. In fact, it upset him. Izaya's expression was hard to read. He was smirking. However, his smirk almost came across in an ' I know something you don't' kind of way.

This irked him. Amaimon liked to be the only one to pull tricks. He tried to keep down his anger and annoyance since he had no reason to lash out yet. He was still new here, and therefore still figuring things out. Amaimon pulled his claw out of his mouth.

"My name is Amaimon; I'm a d-"He almost forgot that he was supposed to be hiding what he was for now.

Izaya raised an eyebrow suspiciously, but he seemed amused.

"-done with this conversation. It's boring me."

Hopefully his apparent bad grammar didn't seem too odd. Amaimon wasn't too sure how normal it was to speak properly in Assiah. This didn't matter much in Gehenna, especially since most of their languages sounded like grunts. There wasn't very much talking in general. Izaya straightened up again after seeing that Amaimon wouldn't return the bow.

"I see. Well, I too find myself constantly fighting boredom."

He started tapping his claws on the counter. He thought about the sweets he currently wasn't having, and started biting his tongue.

"You stand out pretty well, don't you?"

He stopped both actions. "What do you mean?"

"Well, you have green hair done to look like a spike. You appear to have fangs, and your nails look like claws."

Amaimon was shocked by this revelation. He hadn't even thought about how much he stood out. It never really mattered before. He really wasn't very good at this was he? How was he going to pull this off?

"You know, if you're so determined to get sweets I could show you where to go. I am an info broker after all. You also seem like you could use some help working your way through this city. I could help you out. Do you have somewhere to stay? There's extra room in my apartment if you'd like to stay with me?"

As he made eye contact with Izaya, Amaimon showed his first emotional expression by raising an eyebrow.

"Why would you do that for me? We've only just met."

Izaya spread a smile on his face that reminded Amaimon of a certain evil someone.

"Simple. In my line of work, I like to see things interesting happen. It's how I cure my boredom. You definitely seem interesting. I'd like you to stick around here for my own personal entertainment. I'd be curious to see how you'd interact with other certain characters of this town." This man almost reminded Amaimon of his brother.

On the outside, he clearly appeared to be a human, but his mannerisms and persona were that of a demon. How interesting…

"Alright."

After their food came they both ate and headed out of the restaurant.

"Now there's some people who I think are perfect to show you where the candies are. I can introduce you to them now or, I could show you the apartment. I don't really care which one we do now, I'm currently not on a job for once."

Amaimon thought for a moment. Then, out of nowhere-

"IIZAAYYAA!" A loud, gruff voice roared. From out of nowhere a vending machine came flying towards them. Izaya did a flip to the side nearly missing it. Being caught off guard, Amaimon quickly hovered to the side out of the way.

A few seconds later he landed on his butt. Good thing he had only been a couple of inches off the ground. He grumbled. Curse this weak host and my still weak powers. He didn't think anyone noticed him hovering.

"Why Shizu-chan, you almost hit me and my friend here."

'Shizu-chan' (as Izaya called him) appeared to be large muscular man with blonde hair, who was wearing a bartender's outfit and glasses. His hair also appeared to be down, but falling around his head.

"Friend?" Shizuo shot a questioning glance at Amaimon, but then focused again on Izaya.

"Why can't you just stay out of this retched town? I'm tired of you constantly messing with my friends." Shizuo threw a sign at Izaya, that managed to hit him this time. He flew back into a wall. Izaya winced from the impact, but then huffed. Izaya stood up, as though no longer fazed by the fact that a street sign previously hit him. He brushed himself off. Some faint bruising could be seen on his skin.

"Why, you know I can't do that. This is way too much fun." He got out a flick blade and pointed it towards Shizuo. Smiling ferociously, Shizuo pulled a street sign out of the ground and pointed it at Izaya. People around them were watching and talking, some quickly rushed off to get out the way or hid.

"Oo." Amaimon stood up and clapped his hands together. Finally, something interesting. He smiled gleefully to himself.

"Yay! How fun! Fights are very entertaining to watch."

Having noticed Amaimon's reaction, Shizuo glared at him.

"You think our fight is fun, huh?"

Amaimon nodded, nearly hopping in place. "Especially with one as demonically strong as you."

The sign hit the ground as he dropped it and then Shizuo was holding Amaimon up by his coat collar.

"What was that you said?"

Amaimon laughed. He loved it when things were different.

"How exciting this must be!"

Shizuo attempted to throw Amaimon, but Amaimon quickly flicked Shizuo in the head and escaped from his grasp. Shizuo seemed more surprised by how strong the flicking was, rather than hurt. He didn't even wince. He just scrunched his eyes for a moment. Then Shizuo growled and threw a sign at Amaimon. Amaimon quickly flipped out of the way. He came up behind him and kicked Shizuo to the ground.

While Amaimon was standing next to him, Shizuo grabbed his ankle and threw him towards the closest wall. Amaimon laughed. He hovered for a moment just in time to avoid hitting the wall. However, just like earlier, he suddenly stopped hovering. He smacked into the wall and hit the ground hard. A groan sounded from him.

Amaimon wasn't used to this. He preferred being able to have his powers. After all, he was a demon king. At the time it had seemed to be a victory to be finally strong enough to possess something bigger than a hamster, but he only wished he could regain his full strength again. Everything was hurting, it wasn't fun.

"Shizu-chan, as much as I would love to see you get in trouble from fighting, I'm not yet quite ready for this one to die yet."

Amaimon could faintly hear Shizuo seething. A phone rang.

"Hello?" Shizuo paused.

"Yes. I'll be right there." He removed the phone from his ear.

" You lucked out this time flea! But I don't want to see your face here anymore."

Amaimon looked up to see Izaya bending over him, smiling.

"You're definitely going to need help blending in here."

A/N: Akuma means demon in Japanese, at least according to google translate.
