[No One's POV]
The battle has began as Y/n and Vanita charged at each other with Keyblades clashing..

???: Y/n!

Y/n turned his head to see his team with the other students and the professor. This gave Vanita the chance to push him back with a hard kick

Vanita: Let's take this somewhere else.

Vanita created a dark sphere and it big enough to consume herself and y/n. By the time the sphere shrinked back, they were already gone..

Ruby: Y/n!!

Mason: He'll be fine.

Yang: How do you know?!

Sora: My brother is strong. He will defeat her.

Glynda: For now, we have to return to beacon.

Weiss: Are you sure about that, professor.

Jane: Well, we obviously can't stay here. We'll be targets to Grimm if we be here longer.

Kairi: She had a point.

Glynda: Then it's settled. Let's move

Everyone gathered together and started walking to the Bullhead
While they were walking, xion was feeling a little worried about that  Vanita girl.

Xion: Be careful, Y/n. I hope you come back..

In the Station of Awakening..

Y/n landed in a large glass panel with some of his friends in it..but also three unknown people and Vanita too..

(Vanita is still female)

Y/n: Where am i?...

???: Now prepare..to have your heart extracted.

He turned his back to see her floating down and standing infront of him. In her right-hand was an incomplete version of the X-blade which was slightly covered with an aura of darkness. It also had chips in the side of the blade, part of the filigree on one side was gone, and part of the hilt is missing, making it look broken. It also looked corrupted with darkness..

Y/n: The hell is that thing?

Vanita: The X-blade. The one thing that will bring your doom..

Enter battle music

Before the fight began, y/n chanted something quietly from Vanita's ears..

"Heaven, lend me your gift" y/n muttered

A blue aura enveloped Y'/n's body, glowing with pure light. Multiple swords of light appeared, hovering behind t'he keyblader back in a wing-like formation, reminiscent of an angel's wings. Y/n activated his armor and prepared himself..

Vanita struck first by rushing forward at y/n with a spinning slash, swinging the X-blade around. He leapt back, dodging the attack. Vanita attacks again, whirling forward at him with a downward slash and an uppercut. Y/n held up his Keyblade, blocking both blows. However, the uppercut knocked y/n back, making him slide across the pillar.

"Show me anguish!" Vanita says

''I'll show you something all right.." y/n growled

Vanita raises up the X-blade and began charging up an enormous amount of energy. As soon as he was fully charged, Vanita leapt up and slammed the X-blade down, creating a shockwave which emitted an X-shaped pattern.

"Oh, damn" y/n jumps back, dodging the shockwave. Vanita continued his attack with a rushing strike, spinning the X-blade infront of him, but y/n rolled over to the left, evading the attack. Then, Vanita leapt up and swung the X-blade, launching an X-shaped blast toward Ventus who instinctively leapt out of the way.

Now, it was his turn to strike. Y/n rushes forward at Vanita and slashes him multiple times with the light swords, leaving behind an afterimage with each strike. He then struck her with a flurry of quick slashes whilst performing acrobatics. First, y/n whirls forward with six diagonal slashes, three left and three right. Next, he thrusts his Keyblade at Vanita and follows up with six cross slashes. Then, he delivers six more slashes, three with a backflip and three with a somersault.

"Im sorry, bitch. Did that hurt?" y/n mocked

"Screw you, you ass!" Vanita yelled

Both y/n and Vanita charge at each other and the two Keyblade Wielders clash. They both teleported back and forth, leaving behind afterimages of themselves, striking each other with multiple, quick slashes.

Vanita rushes forward at the armored Keyblader while cloaked in an aura of darkness. Y/n stood where he was and held Oblivion back, charging up an enormous amount of pure energy. Just as it seemed Vanita was about to hit him, y/n performs a powerful spinning attack, summoning multiple columns of light which hits her, sending Vanita back.

Y/n rushes forward at Vanita and slams into her with his light swords spinning around him. He then Afterwards, he leaps up into the air and throws his light swords down into the ground, creating a circular magic emblem of light. He then lands in the center of the swords, causing a brilliant shockwave of light to blind Vanitas and inflict tremendous damage to him.

Vanita was down on one knee leaning against the X-blade for support. She looked at y/n who stood infront of her with a serious look on his face and stood up onto his feet.

"Playtime's over, Vanita." Y/n says

"No! I won't accept defeat!" Vanita screamed

Vanita leaps high up into the air and slammed the X-blade into the ground, shattering the pillar into pieces. Soon, y/n and Vanita were both hovering in nothingness, staring each other down.

"Whoa!" Y/n yelled trying to balance himself in the air.

"There's no escape!" Vanita says, charges at y/n.

"You think i'm fucking scared of you? "
Y/n clashed Oblivion with Vanita's X-Blade. With Vanitas left weakened, y/n charges at him and bounces around, striking him with his Keyblade, creating five intersecting columns of crystallized light that trapped him.

"It's over!" Y/n says.

In that moment, Ventus flew down at Vanitas and finishes the fight with a final, powerful strike that knocked the X-blade out of Vanita's hand. The X-blade began to float away from the female Keyblader who tried to grab it. She reached for the ancient weapon with her hands, but the X-blade floated further away from her. to no avail. The X-blade soon shatters into pieces, becoming shards of light.  Vanita floated down toward the pillar and fades away in a bright light.

[End of fight..]

Y/n: Damn. That was intense. *Looks around and only sees darkness with minimal light* How can I escape now...

???: it can show you.

Y/n: Huh??

A white orb of light floated onto y/n's hand. It glowed major bright, causing him to look away. It lasted for a few seconds before it stopped..

Y/n: *feels his hand holding something, and looks* W-what the hell?!

The armored Keyblader stood shocked at what he's holding. The X-blade that Vanita used in their fight. The only thing is..the weapon looks brand new and filled with pure light.

???: This is the Complete X-Blade. Guardian of Kingdom Hearts itself. It seemed to have chosen you to be it's wielder.

Y/n: But why? Why would it chose me?

???: The light inside your heart is powerful, enough to counter the deepest of all darkness. And you are one with the rare power to give Nobodies a heart of own.

Y/n: That is true. Now all I need is to think of a way out.

???: That's easy.

Y/n: Huh?

???: Aim the blade in front of you, shall a portal come your way.

Y/n:..ok.

???: You'll be the one. Until we meet again.

The voice started fading out, leaving y/n to himself. Using his mind clearly, he aims the X-blade in front of himself and thought of the place he was last time..

Y/n: I hope my friends aren't worrying too much.

Next thing, the blades part of the weapon glowed with energy before a stream of light shot out, expanding to a human sized gateway..

Y/n: Home..here I come.

Y/n floated near the portal, as he entered it and escape the unknown void.

[Xion's POV]
We made it back to beacon and it was 6:00pm. I was in my room, still wondering of when y/n is gonna come back..

Xion: That Vanita girl seems like trouble. What if she tries to take y/n away from us? I don't know if I can't beat with that.

Kairi: Hey, xion.

Xion: *Snaps out of thought* H-huh?

Kairi: *smiles* Looks who's back..

She moved out of the way to see y/n behind me smiling. He walked towards me and placed a hand on my cheek..

Y/n: Hey. I'm sorry for making you worry.

I latched onto him and smothered him in kisses. We fell to the ground with me being on top, and i kept giving him my loving assault

Kairi: *giggles and grabs door* I'll leave you guys alone. *closes door*

Y/n: *pulls me back a bit* Wow..

Xion: I'm sorry.. but i couldn't bear seeing you go.

Y/n: Hey. No one is gonna take me anywhere, away from you or the team.

I smiled at what he said and hugged him harder, while nuzzling my head onto his chest..

Xion: I really am clingy to you.

Y/n: True. But I really don't care. I like this bubbly cute side of you.

Xion: *pouts* I am not cute.

Y/n: *sits up and pets my head* Yes you are.

I sighed and got off of him..

Y/n: Since we don't have school tomorrow, what do you think we should do?

Xion: Hmm...why don't we all go to Twilight Town? We haven't seen Roxas, Naminè and the others since we left.

Y/n: I like that.

???: Hey, guys.

We turned to see Sora, Mason and Kairi standing near the doorway..

Kairi: We saw an movie theater about to play (favorite/movie) in central vale. Do you wanna come with us?

Y/n: I'm down. How about you?

Xion: I don't mind. Luckily, we have no classes tommorow.

Mason: Let's go then.

We all got up and walked out of our dorm.

Xion: *thoughts* I wonder what's with the heartless? They have showed up, since we arrived in beacon.

In another world..

We can see a area made up of unending, rocky badlands, twilight sky and many Keyblades, standing into the ground rusted. This is the Keyblade Graveyard..

Up top on a hill, is a old man with brown skin, a small silver goatee beard. His is composed of a white and black coat with a red inner lining, over a white shirt with two thin black belts, as well as white gloves and calf-high black boots. The major difference between the two outfits is that Ansem wears the shirt unbuttoned, exposing the Heartless emblem on his chest. there are some minor changes; Ansem's coat has gold lining on its edges, where this man has black lining. This is Master Xehanort..

???: Xehanort.

Xehanort: Hmm? *head slightly turns to see Ansem*

Ansem: It appears your pupil has been defeated.

Xehanort: *sighs* Vanita always have been over-confident with her own skills.

Ansem: Should I retrieve her?

Xehanort: No. She has failed me twice.

Ansem: The Boy y/n.. somehow gained the power of the X-Blade.

Xehanort: oh?

Ansem: He's getting stronger throughout the passing time.

Xehanort:..i see.

Ansem: *makes gateway* Looks like Kingdom Hearts is give him more power. I wonder how much..*walks through portal and closes it*

Xehanort: *give a small smile* Yes..*strokes his goatee* I wonder as well..

[In the Emerald Forest]
In a wide clearing, a purplish translucent circle appeared out in the open and sonething or someone was being pushed out. The dark uncovers to reveal Vanita, in different clothing..

The circle disappeared, and Vanita started to wake up. The only problem is.. She doesn't know where she is..

Vanita: *groans* Huh? *looks around* W-where am i? And what is this place?

Vanita tried to remember something, but sadly her mind showed nothing..

Vanita:  Why can't i remember?

Vanita then started to walk forward, maybe trying to find help on where she is...
