Hi, guys! K.D. here! This idea started running through my head yesterday and I thought it'd be cool to do. I don't know why I chose "This Is War", but I guess because it's one of my favorite songs.

Summary: The Golden Trio plus Neville and Ginny team up with Draco, Blaise, Pansy, Daphne, Vinny, and Greg in this songfic.

Disclaimer: I do not own Harry Potter or "This Is War".

Slythindor: This Is War

The Great Hall went quiet as Harry Potter—The-Boy-Who-Lived—and Draco Malfoy—The Slytherin Ice Prince—walked up to the platform where all four tables could see them. They turned to face the students, wands in hands, and raised them toward the enchanted ceiling. From Harry's wand burst a golden lion. It roared and reared up on its hind legs, mouth open in a snarl. From Draco's wand erupted a green snake. It slithered through the air toward the lion, wrapping itself around the King of the Jungle's torso and head. The other occupants of the Hall gasped as both boys sent each other identical smirks. This was a symbol of House Bonding. There hadn't been one for centuries, but never had there been one between Gryffindor and Slytherin. As natural enemies, the two Houses would never to have thought to be united. The Sorting Hat had been right, though; this needed to happen in order to survive.

Harry raked his fingers through his hair. Part of his brain was wondering why he was doing this. But, he knew why. This was what he had to do. What he wanted to do. If he couldn't get the whole school to help battle Voldemort and he army of Death Eaters, then they would surely lose. What better way to unite the houses than to start with the biggest rivals? And what better way to unite said rivals than through provocative song? Behind them were Ron and Blaise on guitar, Hermione and Daphne on keyboard, Neville and Greg on drums, Ginny and Pansy with two microphones, and Luna and Vinny on bass. He gave Draco a grin and held up a microphone. The guitarists played slowly and Harry started to sing.

"A warning

To the people

The Good and

The Evil.

This. Is War."

Draco opened his mouth as Harry stepped back.

"To the soldier

The civilian

The martyr

The victim

This. Is. War.

Ginny and Pansy picked up together.

"It's the moment of truth

And a moment to lie

A moment to live

And a moment to die

A moment to fight

A moment to fight

To fight, to fight, to fight!"

Draco and Harry started moving around as the others brought their instruments to life.

"To the right

To the left

We will fight

To the death!

To the edge

Of the Earth

It's a brave new world

From the last to the first!

To the right

To the left

We will fight

To the death!

To the edge

Of the Earth

It's a brave new world

It's a brave new world!

Things slowed down again and Ginny and Pansy did a two small chorusus of "Ooh oh ooh oh ooh oh." Harry walked forward.

"A warning

To the prophet

The liar

The honest

This. Is. War."

Draco wrapped an arm around Harry's shoulders and gestured to him as he sang the next line.

"Oh! To the leader

The pariah

The victor

The messiah!

This. Is. War!"

This time, the others joined in with Ginny and Pansy.

"It's the moment of truth

And a moment to lie

A moment to live

And a moment to die

A moment to fight

A moment to fight

To fight, to fight, to fight!"

Ron and Blaise made themselves even more known by spinning around on their guitars. Greg and Neville made a show of banging on each other's drums.

"To the right

To the left

We will fight

To the death!

To the edge

Of the Earth

It's a brave new world

From the last to the first!

To the right

To the left

We will fight

To the death!

To the edge

Of the Earth

It's a brave new world

It's a brave new world

It's a brave. New. World!

The guitars stopped for a bit while the keyboardists and drummers did their thing. Harry and Draco started to dance to the beat, spinning and shuffling while the other students in the Hall started clapping. When the dance was done, the boys started walking between the tables, wrapping their arms around the shoulders of students. From in between the grinning Fred and George, Harry sang:

"I do believe

In the light

Raise your hands

To the sky."

Draco squeezed Marcus Flint and continued.

"The fight is done

The war is won

Lift your hands

Toward the sun."

They swayed with their companions and sang in harmony.

"Toward the sun

The other musicians started to sing the "It's a moment of truth" part continuously in the background.

Toward the sun

Toward the sun

The rest of the school, including the teachers all stood from their seats and began to chant "Fight! Fight! Fight! Fight!"

The war is won.

On the final loud and long shout of "FIGHT!", Harry and Draco jumped up and ran back to the platform as the music kicked up again. Luna and Vinny switched places with well-choreographed twirls and Hermione and Daphne ran their hands across the keyboards. In unison, all twelve of them belted out the words:

"To the right

To the left

We will fight

To the death!

To the edge

Of the Earth

It's a brave new world

From the last to the first!

To the right

To the left!

We will fight

To the death!

To the edge

Of the Earth

It's a brave new world

It's a brave new world!

It's a brave. New WORLD!

Ginny and Pansy broke into choruses of "Ooh oh ooh oh ooh oh oh!"

A brave new world!

Ooh oh ooh oh ooh oh oh!

The war is won!

Ooh oh ooh oh ooh oh oh!

The war IS WON!

Ooh oh ooh oh ooh oh oh oh!

A brave new world!

Everyone yelled and screamed, clapping and stomping their feet. The Weasley twins lead the whole school in a chant:

"HOGWARTS WILL FIGHT! HOGWARTS WILL FIGHT! HOGWARTS WILL FIGHT!"

The twelve musicians laughed and hugged each other, Slytherins and Gryffindors, hoping that with their song and union could bring themselves together to end Voldemort's reign of terror. Ron and Blaise high-fived, Hermione and Daphne exchanged teary hugs, Vinny piggy-backed Luna around the platform, Neville gave Greg a playful noogie, and Ginny and Pansy hooked arms and danced in a circle. The two boys up front settled their arms on each other's shoulders. Harry knew that in the end he would be the one who faced Voldemort man to man. He knew that he might die. But, with everyone behind him, fighting with him, he knew that he could win. Draco gave him a light headbutt, drawing him from his musings.

"Don't worry about Moldy Shorts, Harry."

The raven couldn't help but laugh at the ridiculous name. "I do have to fight him, don't I?"

"You'll win," the platinum blond assured him.

Harry squeezed his shoulders. "We'll win."

They grinned at each other again before facing everyone and opening their mouths wide:

"HOGWARTS WILL FIGHT! HOGWARTS WILL FIGHT! HOGWARTS WILL FIGHT!"

The things you can do when your brain randomly supplies you with story ideas. So, did you love, like, not like, or hate? Let me know. And if you didn't know that song, that was "This Is War" by 30 Seconds To Mars. The first time I heard it was when I watching a Katekyo Hitman Reborn (Love that anime!) AMV on YouTube.
