The wind began to blow by as You stared everyone down, a complete dead silence filled the atmosphere as you began to walk towards everyone

Rias: Kiba! Xenovia!

Without Hesitation, Kiba and Xenovia rushed towards you as they summoned their blades in their hands, they had a strange emotionless look in their eyes as they began to swing their blades at you

You dodged all of the slashes without effort or even thought but Kiba and Xenovia didn't stop, you let out a loud roar that blew both of them away and sent them towards the other devils

Y/N: Something's not right...

You then bolted towards the Devils at Mind boggling speed as you appeared in front of Issei before Kicking him away and off the building

You then turned to Sirzechs and punched him in the side making him gag a little, you then leaped into the air and formed a dark blue orb of Ki in your hand before blasting all of the devils with it

All of the Devils were launched into the air and  went flying everywhere, you then began to zoom towards them and strike them one by one

They all landed on the ground as you slowly descended to the ground as well, The Devils slowly got up as two little girls with Chainsaws approached you

Y/N: Your little weapons are useless against the Power of Ultra Instinct...

Iru: You won't be saying that...

Neru: ...When we slice you into a bunch of little pieces!

They began to recklessly swing their chainsaws at you as you continued to dodge without even thinking, you kicked Iru in the stomach making her slide a few feet away and blasted Neru away with a small Ki blast, the two got up and stared you down

Iru: He's...

Neru: ...Dead Meat!

before they could do anything else you forced your arms out creating a massive gust of wind and blowing them away

The two twins slid on the ground and into the woods as Riser glared at you with full intent to kill

Riser: Get him! I want him dead!

Suddenly two more girls with Cat like features like Koneko and Kuroka along with questionable outfits leaped into the action

Ni: Now it's our turn!

Li: Let's get em!

You stood tall without any fear whatsoever and glared at the two girls

Y/N: Come at me...

The two began to run towards you at fairly high speeds for Devils, you braced yourself as they began to constantly swing at you as you once again effortlessly dodged

Li: Stand Still will Ya!

You then smashed your fist into Ni's stomach making her gag before kicking her away, you then turned your attention to Li before you blasted her away

Y/N: It's no use...

You leaped into the air and began to fly before stopping charging straight towards the Devils with your fist out in front of you

Y/N: This is the end!

Your fist opened up revealing a dark blue orb of Ki, you then fired a large Ki wave blasting over half of them and obliterating them, the only ones that that were left were Rias, Issei, Saji, Vali, and Sirzechs himself

Issei: Everyone!!

Saji: They're gone!!

Y/N: Oh quit you're whining...I doesn't matter anyway...

Meanwhile In The Saiyans' Room

Lotus was sound asleep in his bed when he suddenly heard a loud explosion come from outside, he was awoken from his sleep and got up from bed

Lotus: Ugh...Who could be up right now...?

He saw nobody outside and shrugged it off, he then turned around to see that you were gone

Lotus: Ah Crap...

Back To You

You were fighting both Saji and Issei at the same time, Issei was trying to hit you while failing miserably, while Saji had a rope wrapped around your arm while draining your power

Issei: It's only a matter of time until you get tired now!!

Y/N: Really...?

Suddenly you turned towards Saji while still dodging Attacks from Issei, you then used the rope to pull Saji towards you before you punched him in the gut making him gag

You then put your palm out in front of his face as a flash of light appeared in his face

Y/N: Disappear...

Suddenly Saji was blasted by a large blue Ki wave as he was soon overwhelmed and Obliterated, leaving Rias, Vali, Issei, and Sirzechs left

Y/N: Who's next...

Suddenly you felt a large energy approaching, you looked to the side and spotted an unknown adversary flying towards you and the Devils

Issei: Who's that?!

Y/N: A new enemy?!

You watched as the unknown entity got closer and eventually you were able to see what he looked like, he stopped right above everyone and watched the commotion

???: Well, This is where that large energy was coming from!

Suddenly the Entity showed themselves to reveal a Saiyan with messy black hair with red bangs

(He's in base form)

Y/N: Who are you?!

???: I'm not bad! I promise! My name is Kasai, I just sensed a powerful energy and I followed it!

Suddenly the Saiyan named "Kasai" flew down to ground level and landed next to you

Kasai: Why don't you let me lend you a hand?

Suddenly you reverted back to your base form before transforming into Super Saiyan 4, the two of you stared the remaining Devils down

Kasai: ...Those guys over there...

Y/N: I know...They're not the real devils...

???: Oh? Looks like the cats out of the bag!

Suddenly Another being warped behind the Fake devils with a smile on his face, this one you recognized immediately

Y/N: Karuza!

Karuza: Yes Yes, It's time for our battle to begin, Ark has broken free and will emerge shortly, so this is my last change to fight you...

Y/N: Hmph...

You then got into a fighting stance and stared him down

Y/N: Then let's do this!!

Karuza: Uh-Uh-Uh! First...

Suddenly Karuza snapped his fingers, causing the Fake Devils to turned into Black smoke that soon spread everywhere, when the smoke cleared you all looked to see a bunch of armoured entities that resembled Issei's balance breaker, there was at least 250 of them in sight

Karuza: Now any of your friends that try to interfere will have to deal with my army!

Lotus: Look out below!

Suddenly Lotus, Caulifla, and Kale leaped Down towards you and Kasai

Y/N: Lotus!

Caulifla: Ha! What did we miss?

Y/N: Karuza's back, I'm the one who has to fight him...Don't Interfere...

Lotus: Also who's this?

Y/N: He said his name is Kasai, if you guys could deal with the army that would be great!

Caulifla: Heh, I bet I can eliminate more than you guys!

Lotus: You're on!

Kasai: Let's go!

Kale: Right!

The four rushed towards the army of armored warriors and began to clash with them, in the meantime you and Karuza stared each other down before flying towards each other

Y/N: Let's do this!!

Karuza: Don't blame me if you get hurt!!
