The world of anime isn't just of anime. All the virtual singers of Japan are there, and one more group, the ponies of Equestria. Three different worlds shall collide to see which world is the best.

(Author's note: I love all three worlds, and this was made for fun. Sadly, I couldn't say that it was a crossover of all three. I hope you enjoy my story.)

The character of D. Gray-Man, the singers of Vocaloid, and ponies of My Little Pony enter the stadium with many fans watching form their computers. One fanboy shouts "Go Rarity! You can beat them all with your beauty!" Rarity blows a kiss to the fanboy, as Spike gets angry and starts mumbling to himself. Music starts playing, and its Hastune Miku's World is Mine. Miku is singing it on a stage that no one had noticed before now. Everyone watches her, as fanboys of Miku whistle, happy to see her. Once the song is over, Princess Celestia walks out from behind stage.

"Welcome everypony! We are glad to have you all here!" yells Princess Celestia, "We will now start our battle of the worlds!"

Everyone there looks surprised, not knowing what to do.

"Everyone, we are first going to start with singing between Twilight Sparkle and me! Hastune Miku!" yells Miku, smiling happily. Twilight is surprised, and cautiously walks to the stage. Princess Celestia walks off stage and Twilight walks onto the stage. Miku smiles and gently hugs Twilight, "Let's just do our best."

"Alright," says Twilight, willing to just have fun. Miku hands her a microphone, and Twilight uses a levitation spell to hold the microphone.

"Alright everyone, I will start with singing World is Mine!" says Miku, really happy too, as all the fans of her scream out in happiness. She starts singing the song, and here it is in English for everyone/everypony.

Inhale the joy

Inhale the fun

Now it's time for me to get on top

Of the world

Inhale the music and the warmth

The crowd is ready to bring me to the top

Of the world

'Cause the world is mine

I won't stop this time

Cause the world is mine

And I'm feeling so divine

I'm part of this illusive show

Time for me to get on stage

Lights fade

Tomorrow you'll be at my feet

Saturated senses set me free

It's all I need

'Cause the world is mine

The world, the world is mine

I won't stop this time

I won't stop this time

'Cause the world is mine

The world, the world is mine

And I'm feeling so divine

Because the world is mine

I won't stop this time

The world, the world is mine

I won't stop this time

Oh no

Oh no

'Cause the world is mine

The world, the world is mine

I won't stop this time

I won't stop this time

'Cause the world is mine

The world, the world is mine

And I'm feeling so divine

'Cause the world is mine

The world, the world is mine

I won't stop this time

I won't stop this time

'Cause the world is mine

The world, the world is mine

And I'm feeling so divine

'Cause the world is mine

The world, the world is mine

I won't stop this time

I won't stop this time

'Cause the world is mine

The world, the world is mine

And I'm feeling so divine

'Cause the world is mine

The world, the world is mine

I won't stop this time

I won't stop this time

'Cause the world is mine

The world, the world is mine

And I'm feeling so divine

Once at the end, all of Miku's fanboys/fangirls scream out, wanting her to sing more. Miku looks to Twilight.

"You're turn," says Miku, offering her the stage. Twilight cautiously starts singing a song she is making up on the spot. Everyone cringes, not liking the lyrics to the song. She quickly finishes the terrible song, and I shall not put it down, because you will not only hate me, but you will forever be tormented by said song.

"You did great," encourages Miku, having a fake smile on her face. She then turns to the crowd "Next will be Gumi and Rarity singing!" As Miku and Twilight leave the stage, Gumi and Rarity walk onto stage. They take their microphones, and Rarity starts with a song that Spike created for her, about her. After that song, Gumi sings Heartbreak Headlines.

(Author's note: Sorry to disturb the story, but if you haven't heard any of these Vocaloid songs, I suggest you do. They are amazing, and if you haven't heard of Vocaloid, please take some time and listen to their songs, but please don't watch Romeo and Cinderella, it's not what it sounds like.)

Here is Heartbreak Headlines lyrics for you.

The news we report next is that the results of its survey on heart-broken people of the previous year was announced. The annual number of people who lost love is about 12,000,000...]

The annual number of broken-hearted people is about 12,000,000

And that means about 23 people are dumped per minute

Even at this moment, precious love is lost at somewhere in Japan

The government is asked to provide solutions for that

*For your information, the number is not based on any accurate surveys or exact statistics.

If there is love that you can save by loving someone

Your pure love might change this world, maybe.

For example, if a girl steals my heart and then suddenly disappears in front of me one day,

Surely I will be torn apart

I won't be able to do a thing and Japanese domestic production will be less than average year

*For your information, the assumption has no clear basis or solid proof

Though love that you can save by loving someone might be nowhere

And your love might not be able to change this world

If you love someone and that saves yourself,

Your pure love might change this world, maybe, maybe not.

All of Gumi's fans cheer for her, loving her voice. The singing continues for some time, with Kaito, Rin, Len, Haku, Akita, and Zastune Miku also singing for the Vocaloids. Then Princess Celestia, Princess Cadence, Applejack, Pinkie Pie, Rainbow Dash, and Fluttershy also singing for the ponies. This is the end of the first day, and many fans of either group killed their voices during it.
