You had just finished a new transformation as the others were checking out your new look, obviously surprised by the sudden change in looks and power

Lotus: Both halves of his hair are different colours...and same thing goes for his eyes!

Kaminari: He kinda looks like you, Todoroki...

Todoroki: Yeah..."Kinda"...

Goku: What's up with his energy...?

Vegeta: It feels so pure...but at same time so maliciously evil...!

Gohan: How is that possible?!

Beerus and Whis took a closer look at the holographic screen as they began to sense heat coming from your direction

Beerus: He's not just generating energy...he's emitting heat...

Whis: It's possible that his Devil Form Combined itself with that of Ultra Instinct...

Vados: Yes...that's the only explanation...

Meanwhile

You were currently facing Nega as he got into a fighting stance once again, you gave him a blank stare as you turned to fully face his direction

Nega: No matter how many transformations you may undergo...I will be the one on—

Nega went wide eyed as he realized you were right behind him, you kept the blank stare in your eyes as you reeled your fist back and whacked him to the ground

Nega quickly emerged from the dust and looked up, now wondering just what had happened

Nega: What did he do?! I didn't even see him move...!!

Nega was about to leap but you suddenly appeared above him and thrusted your blade of energy into his arm, pinning him to the ground like a nail as he screamed

Blake: Something's not right...he's doing all this while keeping that emotionless expression on his face, he isn't even talking...

Iida: His strength and speed have increased dramatically, but how did he do that...?

Grand Priest: The form that Y/N has taken is a like modified Ultra Instinct, he is able to move at very high speeds while both his strength and speed have only been amplified by the power of his Devil Form that was added to it.

Nega suddenly grabbed the blade and crushed it with his hand as you simply summoned another one and dashed towards him, getting right in his face before he could even react

You suddenly thrusted your blade into Nega's torso as you then pulled it out and took a quick slash at him, slicing his upper and lower torso into their own halves as a mountain in the distance suddenly cut in half as well

Nega of course regenerated from the attack and leaped back, hoping to gain a safe distance as you bolted after him and landed a nasty punch to his gut, cashing him to gag

You then kicked him into the air and followed him, suddenly bombarding him with a series of punches to his face and upper torso

Midoriya: It seems like his main trait is that unreal speed of his...!

Shin (Supreme Kai): Yes, Ultra Instinct's power must be somehow protecting his dark energy from being absorbed, that along with his speed and he has him outclassed!

You suddenly began to zip around Nega, landing lots of blows in different areas, slowly picking up speed as you eventually went to a speed that most gods could hardly keep up with

Ruby: Where'd he go?!

Whis: He's still there, Just zipping around Nega at speeds that the normal eye can't see...

You kept at it for a good 30 seconds, each one of your blows getting sharper and sharper as you eventually stopped and leg dropped Nega right in the top of his head, sending him bolting towards the ground

You suddenly appeared on the ground below Nega as you wielded your red blade of energy and raised it in the air

Nega: HOW COULD I...BY THE LIKES OF YOU......?!?!?!

You suddenly began to gather energy into the blade, eventually fully charging the attack as you unleashed a large beam of energy at the tip of the blade

Nega was quickly engulfed into the bright light of the beam that you fired, eventually being fully swallowed by the light as a large explosion occurred in the sky

A long silence filled the area as you stood completely still, all while keeping an emotionless expression on your face

Rias: Is it over...?!

Piccolo: Yes, Y/N has won! Nega was no match for him!

You were about to walk away when you suddenly sensed not one but two energies very close by, you came to a halt and looked around, looking right at the direction of the first energy as a girl revealed herself from behind a large boulder

Half of her hair was brown as the other half pink, the same colour scheme for went for her eyes as well, she also had a large pink umbrella on her

She was currently looking at the side of you that had black hair and a normal looking eye, you then turned to face her, revealing your half white hair and demon like eye, cashing her to go slightly wide eyed

You then turned the other direction as other person made themselves known as well, it was another girl, but this one was younger, she had bright yellow eyes and blonde and somewhat messy hair, along with what looked like a school uniform

???: Hehehe! Where's the victim? I heard you scream that you wanted to cut someone up, that's where you had me~

Flashback

Y/N: I don't give a shit about that...I JUST WANNA CUT YOU SOME MORE!!!

Flashback End

You turned towards the direction of the Capsule Corporation building, ignoring the two girls and beginning to walk away

All of a sudden, the ground began to shake as Nega suddenly bursted out of the ground and dashed towards the Girl with Pink and Brown hair

Nega: FINE!! I'LL TAKE YOU AS A HOSTAGE!!!

The girl went wide eyed as you suddenly appeared in front of her and placed your hand out forward in a familiar stance

Y/N: Iakah...

Nega went wide eyed as he suddenly began to disintegrate into small particles of purple energy, eventually there was nothing left as you suddenly reverted back to normal

Y/N: *Sigh*...I should've done that in the first place...but on the bright side...I feel a little better now...

With that you walked away, not even acknowledging the two girls that had just suddenly appeared

Y/N: I need a nap after all of this...

What you didn't know however was that both girls, now quite curious, decided to follow you
