X's ball of Ki was inches away from you and Yang as everyone cried out to the two of you

Ruby: PLEASE JUST GET OUT OF THERE!!

Blake: YANG! Y/N!!

Weiss: C'MON!!

The blast reach the two of you and a massive explosion Occurred from it, everyone was blinded by the light the explosion produced

When the smoke cleared everything saw a huge hole in the ground but you and Yang were nowhere to be found, everyone looked but didn't see any sign of either of you

Uraraka: W-Where are they...?

Momo: An Explosion of that caliber up close...it pains me to say but...they might have been vaporized...

X stood completely still before looking up

X: Hmph...Not bad...

Everyone went wide eyed before looking up to see you slowly descending to the ground with your eyes shut and Yang in your arms

Your feet touched the ground and you put Yang down, she ran over to a tearfully happy Ruby as you stared down X

X: I see...Master never told me of this...

Before he could finish his sentence you appeared behind appeared in front of him in the blink of an eye and swung at him, X jumped over you and slid back as
You appeared in front of everyone else to make sure nothing happened to them

Asia: Y/N! You're okay!

You turned towards X before opening your eyes and staring him down with a mighty glare

Soon enough a blue god like aura began to leak from your body as everyone began to realize what was going on

Aizawa: What is this?

Midoriya: This is...

Rias: The form he used it best Issei in their first fight...!

Suddenly you let out a beast like roar as your aura completely Erupted, your body began to produce an extreme heat that everyone could feel

Y/N: HUAAAAAAAAAAAAGH!!!

Everyone put their arms out in front of them as your aura continued to erupt like an active volcano

Issei: Woah! You guys feel that heat?!

Iida: Something tells me he's even more skilled in this form than he was the last time he tapped into it!

Y/N: This is it, You cannot stop me now...

Suddenly the entire area began to crumble as you once again appeared in front of X with your arm reeled back, X cocked his arm back as well as the two of you stared each other in the eyes

Suddenly multiple explosions occurred in the area at once as the two of you began to exchange blows at god like speeds

Kirishima: Woah...They're so fast!!

Xenovia: Neither of them are showing any sign of slowing down!

More explosions were beginning to occur in the area as you cocked your arm back and shot your fist towards X who managed to dodge to see everything in your path be destroyed by the sheer force of the punch alone

X swung at you as you moved over him avoiding the attack, you went in for a swift kick but X dodged that as well as more explosions occurred

Suddenly you were being bombarded with consecutive punches that you blocked by crossing your arms in front of you

You moved back about a kilometer in the blink of an eye to get some distance but it was no use sense X appeared in front of you again right after

The two of you began to exchange punches at incredible speeds

Momo: It would seem that there are evenly matched...

Rias: Not quite, Look closer...

As Rias said, everyone looked a bit closer to see that you were actually slowly being pushed back

Rias: He may be able to fight swiftly but he's not as durable as he would be in any other forms...so to put it simply...just a few good hits and he won't be able to continue...

The two of you hit back to the ground and began to exchange blows once again, your dodging was getting faster

Y/N: I'm starting to get a better grasp on Ultra Instinct's Power...

You leaped into the air and began to shoot a few Ki blasts at X, he swiped them all away and appeared above you before landing a good sledgehammer to your back, doing some critical damage and sending you back to the ground

Tsuyu: Y/N!!

You barely managed to pick yourself up from the ground as X threw himself at you from above, you barely dodged and leaped away, X then appeared behind you with a Ki blast charged up before you could even realize it

X: Like I said before...It's futile...

With that you were blasted with a massive beam of green Ki that overwhelmed you completely and sent you flying, once the beam dispelled, you could be seen falling to the ground as you reverted back to base form

Kirishima: No Way!

Y/N: D-Dammit...what the hell is this thing?!?!

You bounced off the ground multiple times before settling in on the ground, you could hardly move due to both the damage you had taken and the toll that Ultra Instinct took

X began to slowly walk towards you as everyone was silent, the wind blew through your hair as X crouched down to you

X: Pathetic...if you can't even beat me...you'll never defeat Lord Karuza...

You remained completely silent as X kicked you away, you rolled on the ground and crashed into a boulder, X then leaped in front of you and got one last Ki blast charged up and aimed at you

X: Your fighting Style was worth studying...

Y/N: I...I-I'm sorry everyone...I failed you...

Issei: DAMMIT Y/N!!

Everyone looked at Issei with shocked expressions on their faces

Issei: How?! How could you lose?! You're Y/N L/N?! Everyone is at risk! If you're just throwing in the white cloth just like that...You really are pathetic...

Y/N: S-Shut up...I know that better than anyone...

Tears began to go down your eyes as Issei clenched his fist in frustration

Issei: SO GET UP!!

You then went wide eyed and stared at the ground

Issei: Dammit Y/N...You've made me look like a little bitch so many times now...you even beat me MULTIPLE TIMES in a fight!! And NOW you're just giving up?! You're Superior to me Y/N, by a long shot...I can't even dream of being as great as you one day...SO I'M NOT LETTING YOU GO DOWN WITHOUT GIVING IT YOUR ALL!! MORE THAN THAT!!

Y/N: But I've reached my limit...I BROKE MY LIMIT! And yet I still lost...

Issei: THEN BREAK IT AGAIN!!

Your eyes widened once more as you turned your head towards Issei

Issei: BREAK YOUR LIMITS AGAIN!! SHOW THEM WHAT Y/N L/N IS REALLY MADE OF!!!

X: Honestly...I feel like vomiting...

Y/N: Shut your mouth...

X went slightly wide eyed as you stood tall once again

Y/N: Even if only one person believes in me...

You then looked at X with a look full of pride in your eye

Y/N: THAT'S ALL I NEED!!

Suddenly you began to power up with an aura that blew him away, debris began to fly as your hair began it constantly flash white, your hair spiked up before you emitted pure white energy that blinded everyone

When the light of the energy faded, everyone looked to see you standing tall and facing X once again

Issei: Dammit...you really are awesome...

Rias: He's managed to do it once again...

Midoriya: Honestly...What an unbelievable guy!

Y/N: I'm ending this here...X...Prepare to meet your undoing...
