**************************************

~Onmi pov~

"Yo!, I heard you needed me what's up" Ash said as he stepped out the portal he made.

Ash then looked around and saw Yuji's body.

"Sighhh, based on who was inside his body I can already guess what happened. Well I guess it's up to me to fix this mess"

Ash then went towards Yuji's body and as soon as he place a hand on it, Ash easily made his way inside their inner world.

Once inside he saw Sukuna make a Binding Vow with Yuji "Well do this then, let's kill each other. If you win I'll bring you back to life with no conditions but if I win I'll bring us back to life under my contract"

Yuji easily accepted and said "Fine"

As soon as the word "Fine" left his mouth Ash flash stepped behind Yuji and grabbed his head and quickly slammed it towards the ground, just in time to escape Sukuna's technique.

Sukuna's expression started twisting in anger "You stupid sorcerers are always so annoying and are always getting in the way"

When Ash let go of Yuji's head he slowly stood up while rubbing his forehead slightly as he whined "What was that for"

"To save you from your dumbass decisions, haven't you heard the term to be careful when making a deal with the devil. Well you went and made a losing one and was about to lose"

Sukuna just sent out his technique while Ash pulled Yuji behind him and sent a wave of fire from his hands making their techniques clash.

Ash then flash stepped and appeared right next to Sukuna punching him across the face and sending him flying, crashing onto the bone structure he has built up in his inner world.

Ash then conjured multiple swords made put of fire and sent them towards Sukuna at a very high speed. However none of that seems to have any effect on him, as he just stood up and cut up all the swords with just a swipe from his fingers.

Sukuna then started running towards Ash and started sending multiple Cleaves and Dismantles.

Ash body started being cut as blood soon started pouring out from everywhere.

Yuji just looked at him with shock and worry but before he could express his concern, Ash's wounds started catching on fire and healing themselves back up. Ash then started running towards Sukuna, as Sukuna and Ash were about to meet in the middle, Sukuna totally ignoring Ash.

His main focus has never been Ash... it has been Yuji.

Just as Sukuna was about to appear before Yuji, a dome of fire soon encased him protecting him from Sukuna.

"Tsk, no matter what Era you sorcerers are always such a buzz kill and just as I was about to have my fun."

Ash appearing before the dome just replied back "You're just so predictable "King of curses", it was pretty obvious from the start that you weren't really even trying and just wanted me to get over confident so the binding vow could take place"

Ash just put his hands in his pockets and held his held high and as if he was looking down at Sukuna, he said with glowing purple eyes "Just how pathetic does one have to be to try and trick a child into a binding vow, disgusting"

Sukuna got beyond pissed and made his signature handsign

Before that could fully happen Ash dissolved Yuji's dome and said "This is how sorcerers fight so pay attention"

As Ash made a handsign of his own

[Ash's hand sign]

Almost in sync they said

"DOMAIN EXPANSION: MALEVOLENT SHRINE"

"DOMAIN EXPANSION: IMPERIAL TEMPLE"

behind Sukuna a giant shrine with an open mouth appeared, as the mouth opened bones started come out in the open.

Meanwhile behind Ash a temple appeared with large purple wings made entirely out of fire to the side of it. On the top middle of the temple the symbol of a bird with it's wings spread out in the middle of the sun soon formed.

[Temple and The Symbol]

A giant miniature sun was soon formed between them

Sukuna just watched it like it was nothing impressive.

As soon as their domain enhanced technique made contact the entire inner world was then engulfed in a bright light.

In the real world...

As soon as Ash took his hand off Yuji, he quickly sat back up and started patting his chest right where his heart is.

"Phew, I have my heart back. Thank you senpai"

"Yeah don't worry about it, I was just doing what I was called for. You should have heard Gojo when he called, he sounded pretty worried about you"

"Aww, really sensei." Yuji then looked down on himself and said "Woah, my dick is hanging out."

Gojo ignoring what Ash previously said and just walked up to Yuji "Yuji! Welcome back"

Yuji just smiled and replied "Yo, I'm back".

*High Fives*

Ash seeing their exchange just shook his head and said "Well I'm leaving, I wanna see how banged up Megumi is"

Yuji got slightly guilty when Ash mentioned him but wanted to see Megumi as well and said "Wait let me come with you too"

"Its better that you don't" said Gojo

Yuji just looked at him in confusion.

Gojo then said "It's better if we get your training started first before anything else"

Although Yuji was a bit disappointed he understood.

While Gojo just signal to Ash with a finger by his mouth.

Ash just nodded his head understanding the message and went his away.

...

Megumi who had both of his stumbs wrapped up in bandages can be sitting down next to Nobara infront of the school temple.

"You don't seem worry for someone who just lost his two arms and could never be a sorcerer again" said Nobara

"I know someone that could fix this"

"Is this the first time one of your comrades died?"

"It's the first for a classmate"

"Woah, Megumi you look like shit" Said Ash walking slowly towards them.

Nobara turned heard towards the voice and froze "Holy shit, just who is this hunk" she said in an almost mesmerized voice.

"That hunk is my boyfriend, so watch it first year" said Maki appearing with both Panda and Toge.

Ash just gave Maki a wink to which she just smile in return.

"WH- That's can't be true, right Megumi, please tell me she's lying"

"Sigh, she's telling the truth"

Nobara almost collapsed on her knees as she said "I finally find a hot guy who seems perfect but he's taken, just what is wrong with this cursed city"

Ash ignoring Nobara just walks towards Megumi and said "Do we need to hire a babysitter for every single time you need to go out."

Megumi was soon bathed in a wave of Ash's flames which freaked out Nobara for a sec

Seeing her reaction Ash just laughs "Hehehe, that never gets old". When Ash finished bathing Megumi in his flames both of his arms were soon restored.

Megumi started moving them around and squeezing his hands into fists seeing if there's something wrong with them. Seeing them back and perfectly fine, he let out a sigh of relief "Thank you, senpai"

Ash just waved it off "Yeah, yeah don't worry about it."

Maki who came close to then just tapped her bokken on Ash's head. "Stop doing that so unexpectedly, you almost freaked her out."

"Come one, it's hilarious, you remember Yuta's reaction, he almost fought me when I did it to Toge"

Maki just shook her head at his antics.
