Yes, I know, an entirely overused plot, but I couldn't resist. And I've never read a Harry Potter/ Inuyasha crossover because they're all about Kagome and Inuyasha, whereas I like Sesshoumaru. So...

Enjoy my story!

Harry Potter and the Deadly Alliance

Lord Voldemort was running out of options.

Every bit of ancient magic available to him was nearly spent. True, he had returned to his full power, but he now needed powers to aid his, and anything that he could think of, that senile fool Dumbledore could thwart.

"Wormtail, have you any information!" he snarled, sensing the sniveling, blundering man enter the room. Wormtail stumbled in, shaking.

"M-milord…Kazuma and I…"

"Ah, yes. Our newest Death Eater…"

"Well…Kazuma and I may have found a lead."

"Lead? Go on."

"Demons, milord. It seems that a certain well—the one at the Higurashi Shrine of Japan—can transport one of magical or demonic to the Feudal age of the same country."

"I see…"

"Kazuma himself experimented under the cover of night and a Disillusionment Charm. He encountered a demon…"

Wormtail thought a moment, seeming to struggle with the name.

"It was… Sessho…Sesshoumaru, I believe…"

"And what did he observe?" Voldemort pressed.

"The demon itself was very intelligent, as well as cutthroat to a fault. It demanded to be referred to as a lord itself, which suggest that it was a great landowner in Japan."

"Interesting," Voldemort mused. "This could prove fruitful in our war. No doubt this demon was of a superior animal class from what you say…"

"Inu Youkai…that is, dog demon, sir, according to Kazuma."

"Very well. Send Kazuma back down. I want him to capture us a demon…"

"Inuyasha, sit!"

Said hanyou's face hit the dirt.

"Damn…"

"I'm going home, Inuyasha! Don't try to stop me!"

"Why would I!" Inuyasha spat.

"Oh? You mean you can see the shards?"

Inuyasha's face went blank for a moment.

"…hey, wait! Damn!"

Inuyasha sat back down.

"Ugh! What could possibly go wrong now!"

"Inuyasha."

"Oh, great," he growled in annoyance. "Just the asshole I need to see right now. Came looking for a fight, Sesshoumaru?"

"No."

"Well then, let's…huh? You don't want to fight?"

"No. I merely need to ask you a question," the taiyoukai replied.

"No promises on an answer, bastard."

Sesshoumaru sat a fair distance across from Inuyasha and sighed.

"Inuyasha…Do you know of any humans from the continent?"

"Huh?" Inuyasha said stupidly. "No, I don't."

"…"

Sesshoumaru stared very hard at his brother, ears tweaking and nose twitching. He actually looked quite comical, but his antics were ticking Inuyasha off.

"Ya don't need to do your demonic lie detector test. I'm tellin' the truth!" Inuyasha snarled in annoyance.

"…very well."

Sesshoumaru stood to leave. He walked twenty steps and then came to a halt.

"There was a ningen here. He wore black silken robes and smelled of cunning and deceit. If you see him before I do…well, let us just say information is welcome…"

With that, he strode into the deep forest.

"Huh. What was that about?" Inuyasha wondered.

"Very peculiar…"

"Albus, what could it mean?"

"Minerva, you know what it means," replied the man to his companion. His half-moon spectacles rested on his crooked nose as he took in the information from a sallow-skinned man.

"So time is being manipulated by a mere child?" the woman asked.

"Indeed, Professor McGonagall."

"The Dark Lord plans to amass the demons from this era of feudalism and bring them to our war," the pale man confirmed.

Albus Dumbledore, headmaster of Hogwarts, nodded.

"We must see this girl."

"Oooh!"

Kagome stomped up to her room.

"That jerk! Calling me a shard detector!" she fumed. "I can't believe him!"

Kagome Higurashi flung her pack down and dove into her pillow.

"I oughta squish his jerky jerk head!" she roared, pounding her pillow with her fists.

"Kagome!"

The girls sighed.

"Yeah, Sota?"

"Letter for you! It's on your bureau!"

Kgome dragged herself out of bed forlornly and reached for the letter her brother had told her about.

"Strange. It looks like a parchment envelope."

She examined the address.

To: Ms. Kagome Higurashi

The Second Room to the Left

Tokyo

Japan

Geez! That's precise, she thought in awe. She pulled out a letter that bore a seal at the top. There was an "H" in the center of a shield, and in the extra space, four animals were visible; a badger, a raven, a lion, and a serpent.

Ms. Higurashi,

Do NOT be alarmed by the information in this letter. Nor should you believe it as lies.

Greetings, I am Albus Dumbledore, headmaster of Hogwarts School of Witchcraft and Wizardry.

Firstly, I'd like to inform you that we of the wizarding world have become aware of your frequent trips to the Japanese Feudal Era. As of late, this has become a problem for us. There is an evil wizard in our world—Lord Voldemort—who has infiltrated your well with the help of his cohorts. This "cohort" (Death Eater) came into contact with a demon, supposedly named Sesshoumaru.

It is probable that Voldemort intends to use demons from your time. This could ruin the fabric of time, and endanger your family, some things that we would like to prevent…

Kagome sighed. She had experience with time lapses (See first IY movie).

…Ms. Higurashi, this brings me to my second point of business. This demon is rumored to be very powerful, and I myself have researched him. If Voldemort were to control him, it could mean absolute disaster in both the Wizard and Non-Magic Worlds, considering how weak the human world today is compared to Sesshoumaru's era.

I implore you t meet me at the central park this Sunday at noon. There is much to discuss.

Looking forward to meeting you,

Albus Dumbledore.

P.S.: Come alone.

The letter seemed suspicious to Kagome. However, she was sure it was no hoax. Something within her just told her so. So she looked at her clock.

"Ah! Why did today have to be Sunday! It's 11:45!"

"Oh…barely made it…"

Kagome breathed heavily; she had been forced to sprint to make it to the park in time. She stopped to take a breath.

"Ms. Higurashi, I presume?"

She turned to face an elderly man. The man wore half-moon spectacles, flowing purple robes, and had long white hair. His beard reached nearly to the ground.

"Er…Dumbledore-san?"

The man nodded.

"Come," he said in perfect—too perfect—Japanese. "Let us sit."

She followed him nervously to a bench, half expecting him to grab her and run.

"I am glad you cane, Ms. Higurashi," he said warmly.

"Umm…Dumbledore-san?"

"Please, call me Professor Dumbledore," the wizard said.

Please, please R and R!
