Well, I haven't exactly seen any Fullmetal Alchemist/ Inuyasha stories that I wanna read, so I've decided to make my own. This is one story of a set that I'm gonna do. One will be this, in which the Inu crew get stuck in Ed and Al's world, and the next one will be after I know more about FMA, and it will follow the storyline, just with the Inu bros. taking over the Elric bros. roles.

Well, anyway, hope you enjoy the first chapter of Fulldemon Alchemist.

Fulldemon Alchemist

Edward Elric was never the patient one. It had been a while since he'd become a State Alchemist, and still the Philosopher's Stone was not in his palm.

To be frank, he was royally pissed off.

"HUGHES! I DON'T WANT TO HEAR ANY MORE OF YOU FAMILY-BASED SHIT RIGHT NOW!" he snapped.

Lieutenant Colonel Maes Hughes feigned hurt.

"Edward! How could you say that?" he said in mock hurt.

"Because…YOU'VE BEEN SPOUTING OFF FOR TWO HOURS NOW!"

"That's quite enough of that."

Ed turned to see Colonel Mustang tapping his foot in annoyance.

"Hughes, you have a call from East city. Ed, your brother is looking for you."

"Oh, damn. That's right!"

Ed had totally forgotten that he'd sent his little brother Al to hold their train seats until he got there. If he didn't hurry, that train to Resembool would be leaving without him.

"Thanks a load, Colonel! I owe you one!"

"I'll remember that," Mustang snickered. "See you later, Fullmetal."

Inuyasha cursed under his breath.

That's the third Kaze no Kizu he's split! What do I do now?

As if reading his mind, Inuyasha's opponent threw in his two bits.

"So, little brother, do you plan on throwing out useless attacks the entire battle? I daresay I'm becoming bored."

"You know, that reminds me. Have I ever told you what a damn board you have shoved up your ass, you piece of shit?" Inuyasha spat.

"Is that all you can come up with? Hn. I would challenge you to a battle of wits, but it seems that you are unarmed," sneered Sesshoumaru.

"Unarmed! I'll give you unarmed! KONGOUSOUHA!"

With a look of disdain, Sesshoumaru blocked every diamond shard that burst from the Tetsusaiga.

Except for one.

The rogue shard went straight through his wrist, causing him to fumble the Toukijin.

Rrgh! Not good! He thought in annoyance. He reached for his sword, but it was no use. The Kongousouha shard had rendered his hand useless as far as gripping went…

"Brother! Thank goodness you're here! The train was ready to go…"

"Yeah, I know Al. Thanks a bunch for waiting."

Alphonse Elric rubbed the back of his neck.

"It was nothing," his voice echoed. For Alphonse was a suit of armor. That is, his body was a suit of armor. His older brother, to preserve his soul, had infused it with the armor. Such was the fate of those who toyed with forbidden arts of alchemy. Ed had not gone unpunished. For trying to resurrect their mother with alchemy, Al lost his body and Ed lost his left leg. Ed also sacrificed his right arm to transmute Al's soul into the armor. Now they were on a never-ending quest to procure the Philosopher's Stone so that they may get their bodies back. So far, they had made enemies like Scar, but they still (mostly) came out on top…

"Earth to Al! Wake up!"

Al's eyes flickered and he turned to his older brother.

"Sorry. I was just thinking…"

"Don't think so much. It's bad for you…"

Al scoffed.

You could do with some rational thought pattern, Brother…

Inuyasha could have laughed. He'd gotten rid of Sesshoumaru's main weapon, and he'd gotten rid of his secondary weapons—a.k.a., his poison claws.

"Heh! Your hand's looking a little limp there, Sesshoumaru. Could a little diamond shard really do that?"

Sesshoumaru growled under his breath in annoyance.

"Do you honestly believe my hands are my only weapons?"

"Hand, brother. Just one hand."

That pissed Sesshoumaru even more. He'd forgotten about his missing arm. He'd made himself look like a fool for forgetting. Angrily, yet gracefully, he charged his hanyou sibling down and positioned himself behind said hanyou.

"Wha—oof!" Inuyasha groaned as he felt Sesshoumaru's foot dig into the small of his back. "You dirty, rotten cheater, that's below the belt!"

"The last time I checked, that was parallel to the belt level," snickered the demon, quite a distance away by now.

"ARGH!"

Inuyasha began to swing Tetsusaiga back and forth, trying to slice his cocky brother to pieces. However, this only gave Sesshoumaru ample time to show off kendo-like moves and a great deal of self-taught kickboxing technique.

"Stop moving, damn you!" Inuyasha snarled. He was not aware that despite the controlled manner in which Sesshoumaru moved, the demon lord was still only just escaping injury.

Inuyasha has grown quite strong, he mused. Quite strong indeed. I must end this.

And with that, Sesshoumaru darted forward and round-kicked his brother in the face.

"Do you not see? I am not limited to my arm. That is why I was always able to fight you and win!"

"Feh! You on something? I've won battles against you too, bastard. Remember when I learned the Wind Scar?"

Sesshoumaru's lip curled into a snarl.

"What's a matter?" Inuyasha sneered, not noticing his obvious lapse in grammatical sense (A.N.—Does he ever?) "Did I strike a nerve?"

"Big words coming from your position, little brother," spat Sesshoumaru.

"So what if I'm on the ground? All I have to do is get you angry…"

SHLUCK!

"Unh!"

Sesshoumaru's eyes widened. Tetsusaiga was firmly lodged in his gut.

"…And you'll lose your concentration," Inuyasha sneered.

"How…dare…you…?" the taiyoukai managed to mutter, blood trickling from his mouth.

"I win this time, brother. Lucky for you I ain't as ruthless as a demon…"

Inuyasha quickly pulled out Tetsusaiga, causing his brother to groan once more.

"And you're also lucky I'm not like Naraku, otherwise you'd have lost more than just a day of travel."

"You're…more like…Naraku…than you…know…" Sesshoumaru wheezed. "Dirty…half…breed…"

At that, the hanyou kicked his brother's wounded gut.

"Damn you to hell, you bastard!"

And with that, Inuyasha began to walk off.

"INUYASHA, SIT BOY!"

THUMP!

"What…what the hell!" Inuyasha roared from the hole he was now in. "Why'd ya do that for, Kagome!"

"You went too far! That was way beyond unfair!"

"So what? Why does it matter?"

"You don't have to kick him while he's wounded, much less in the wound!" Kagome snapped back.

"Heh…I would have done the same…stupid onna…" Sesshoumaru sneered. He then coughed violently before passing out.

"Finally," Shippo said. "We got rid of one idiot brother…"

Inuyasha was there in a flash to bash Shippo's brains in.

"Whaddya mean by that!" he snarled.

"Sit, boy!"

THUMP!

"Auughh!"

Yes, I know. It'snot goodyet. Well, I needed a good reason for things to fall into place, and this is it. R &R please, and keep in mind that I'm just starting to learn about Fullmetal Alchemist. Oh, and if you have any questions about Inuyasha or Fullmetal Alchemist, ask me and I'll try to answer to the best of my ability. I know more about Inuyasha though...
