Location: Outside of the burning city

No POV

As we continue on with Y/n's fight with Sukuna, the Son of Godfield used his one of his forms known as Kilobyte and punched Sukuna so hard with a black hole energy powered punch that really managed to take some damage upon the demon.

Y/n (As Kilobyte): If you're gonna fight me. Try to fight me seriously, instead of being so damn careless. Even so, whether you drop that ego of yours or not, you're no match for me. I was expecting more from you.

Sukuna then got back up from the rubble of the mountain and he is so pumped up from the fight, he finds Y/n an interesting and worthy foe to fight against and he is willing to force Y/n to join forces with him no matter what it takes.

Sukuna: (Laughing evilly) Talk all you want. I already made my decision after that powerful punch of yours. I will make you join forces with me no matter what!

Y/n (As Kilobyte) (Sighs) (Thinking) He's just like Muzan that felt the same way. Why does this always happen when a powerful villain like him and Muzan wanted me to join them so badly. This guy is a real nutcase.

Y/n then transformed back into his original form before he readies himself for whatever Sukuna is about to throw at him.

Y/n: Quite the talkative one he is.

Then Sukuna charged at him before Y/n threw another powerful punch at Sukuna, which he immediately blocked it with both arms as he can tell how strong Y/n is right now.

Sukuna: (Thinking) Damn. His blow seems to be getting stronger after his decoy clone received my previous attack and how strong that other punch was that made me spit out blood.

Then he felt his own ankles bone crack from the impact as Sukuna now realized that Y/n is not a wizard nor human at all.

Sukuna: I see. I understand now, you're not a wizard or something, right?

Y/n: (Demonic Voice) Insignificant ant!

Then Y/n landed another blow against Sukuna before he yells at Sukuna to who Y/n really is.

Y/n: (Demonic Voice) I am the Son of Godfield! I'm a demi-cat-God, who just wants to have fun and save the people I cared about.

Then without warning, Y/n unleashed a holy-powered punch and punched Sukuna so hard, he was being sent back into the city, destroying a few buildings in the process. Sukuna was lying on the ground after taking such a powerful punch before a mouth appear on his hand as he began to laugh evilly through the hand mouth before getting back up.

Y/n soon caught up to Sukuna as he is not finished with him just yet.

Y/n: Yo! What are you doing? (Thinking) Hmmm...his demonic aura is just as dangerous as Carnage Kabuto from the House of Evolution. His power is just as similar to that mutant insect that can go on a rampage for a whole week through Carnage Mode. And seeing how dangerous he is right now with that amount of demonic cursed energy flowing through him, he is a danger to the human race. I must defeat him before he will completely wipe out all of the humans in this universe before he will travel through the multiverse to kill more innocent lives.

Then Y/n watched Sukuna charge up another one of his powerful attacks to use against him as the Son of Godfield can smell the scent of hellfire from Sukuna as he is going to use the power of hellfire against him.

Sukuna: You're really persistent in defeating me, aren't you?

Y/n: You think you have what it takes to defeat a Demi-cat-God like me? I like to see you try.

Sukuna: Oh really? Then watch this!!!

Then Sukuna clasped the ball of hellfire to compress the ball of fire from the depths of hell itself to use it as a powerful weapon to use against Y/n as he lowered his arms down to perform another attack.

Sukuna: A High level of curse energy compression that only the chosen could witness.

Then Sukuna released the power of hellfire as it began to burn brightly through his own hands.

Sukuna: The essence of hellfire....heavenly agony.

Y/n: Hellfire, eh? I've roasted marshmallows on an open fire pit of hellfire before and it barely even burned me alive. So, I don't why you planned to char my body with that kind of fire.

Sukuna then smiled evilly before putting the fire out, Y/n then waited for Sukuna to do something with the hellfire to use it against him.

Sukuna: No need to worry. I'm just starting to enjoy this fight. So, don't be in such a rush and enjoy the process.

Y/n: Whatever, just get on with it already. I don't have all day.

Sukuna: You can be arrogant now, but what about after you receive this attack?

Then Sukuna did a pose with his fingers like using a bow and arrow as the hellfire formed a fiery arrow before he released the arrow that is headed towards Y/n, only for him to put it out by using his angel wings to create a whirlwind that is so powerful, the hellfire arrow was immediately put out.

Sukuna was completely shocked.

Sukuna: NANI?! He just put out that arrow like it was nothing.

Y/n then breathed in and out, releasing a gust of blue colored fire that formed into a ball then copied the same technique that Sukuna did to the ball of hellfire as Sukuna watched Y/n perform the same attack as he has the power to breathe out Soul Fire.

Sukuna: He can breathe out Soulfire? I'd never seen someone do that before and he just copied my attack.

Then as Y/n performed the same attack by using the same finger pose to form the Soul Fire arrow, but instead of aiming it at Sukuna, he aimed at the sky and released it into the air. Sukuna is confused to know why Y/n would fire the arrow into the night sky until the arrow exploded into the sky like a firework before he saw a barrage of smaller Soul Fire arrows heading towards the city as Y/n quickly teleported away and Sukuna only has a small amount of time to get away before the arrow hit the gorund.

Once they hit the ground, all of the arrows blew up in a massive inferno of soul fire, lighting up the entire city blocks as Sukuna managed to find some cover in an open building as he watched the entire city burn in Soul Fire. Sukuna has never been so amazed and impressed by Y/n's attack method, and he wasn't expecting the Son of Godfield to do that kind of stunt like that before with Soul Fire.

Sukuna: Amazing...this whole city is now covered with Soul Fire and anyone and possibly even me that got affected by the burning embers of the Soul Fire will all be burned into nothing but ash. Still...I managed to avoid that attack on time.

Think again, Sukuna. Y/n is right behind you.

Sukuna: Wait what?

Y/n then kicked Sukuna really hard, causing him to crash into another building before Y/n jumped down to the ground once again as he watched the city burn with so much Soul Fire.

Y/n: You know, you should really pay attention to your surroundings, because you'll never know what's really behind you. Good thing my cloak is completely fire, hellfire and soul fireproof and with all due respect, a hero like me is not cool without his hero suit.

Then Sukuna did a few slashes before charging at Y/n and send out a barrage of attack upon Y/n, as the Son of Godfield endured every attack from Sukuna before Y/n crashed landed in another destroyed building.

Sukuna: (Laughing Evilly) I told you before. I'm still enjoying this fight and I'm not done with you yet.

Y/n: (Teleports out of the building to face Sukuna) Neither do I. But for a demon sorcerer, you're pretty stubborn. It's no wonder why so many people become your enemies because of your destructive powers.

Sukuna: (Thinking) How he is still alive after I unleashed my fury upon him. Does he not realize his position yet, or is he just a stupid strongman than just a Demi-cat-God? Also, why does he call himself a Demi-Cat-God anyway? Is he part cat or something? I can tell by the cat ears on his cloak. (Speaking) I'm not sure what I've done, make many people become my enemies.

Y/n: Is that so. You see, criminals who feel innocent must be punished as heavy as possible. Like my father always said, "Layer on Layer, your demons will haunt you."

Sukuna: I see. Well, then. Prepare yourself. (Does his Domain Expansion Pose) If you can withstand this next attack, I will consider you as an equal.

Y/n: I highly doubt that will ever happen.

CLEAVE BLADE!

Sukuna: (Smiles Evilly) Now you have entered my attack range now.

Y/n: Oh really? Do your worst, Sukuna. I don't understand how this next attack will harm me, but I doubt it will cut me in half or into tiny pieces or the face that you're now throwing small pebbles at me for some strange reason.

Then Sukuna is about to unleash his next attack on Y/n as he charges up more demonic curse energy within to show Y/n how Sukuna means business.

Sukuna: Patience....patience, patience.

Then suddenly, the whole area has changed to Sukuna's own domain expansion...

MALEVOLENT SHRINE!

Then with enough energy, Sukuna unleashed his charged-up attack upon Y/n.

SUPER CLEAVE BLADE!

Then suddenly, Y/n felt a gush of hot fire as it came out of the ground, engulfing Y/n in the purple-colored flames with Sukuna laughing evilly before Y/n slowly walked towards Sukuna with a sadistic smile on his face as Sukuna watched the Son of Godfield walking towards him with that Chesire grin on Y/n's face as can suddenly see him a cat-like creature with his eyes glowing a bright yellow.

Sukuna: Is he even getting hurt at all? Does he even want to die at all? I think he deserves attention or does he....also what's with that crazy looking smile on his face, is he really some sort of strange cat-like creature or a cosmic being from another world. I can't even tell from the flames.

Y/n: (Laughing Demonically like Omega Flowey) Show me a good mouser and I'll show you a cat with bad breath.

Sukuna: What a fool!

Then Sukuna immediately amped up the heat in the flames, but Y/n just getting closer and closer to Sukuna as the demon is starting to get worried by the sight of the demonic Y/n coming towards him as Sukuna decided to go all out on his attack to see if it's enough to stop Y/n from getting to him.

However, Y/n stopped moving as he suddenly transformed into Godfield as it is his turn to deal with Sukuna as he also has enough of Sukuna and his demonic shenanigans.

Godfield: Well. Well. Well. Looks like it's my turn to face off against the most powerful demon in this universe.

Sukuna: Ah, so you're the so-called Godfield that the Demi-Cat-God was talking about. For a second there, I was starting to panic at the sight of him coming towards me with that creepy look on his face. I haven't felt this kind of feeling for a really long time. But no matter, he will beg me for forgiveness once I break his spirit as a form of respect for strong people like him.

Godfield: I beg to differ. My son will never join forces with demons like you. I will show you no mercy and save this universe from the likes of you.

Then Godfield charged at Sukuna at full speed with the demon laughing at Godfield's attempt to destroy the demon of this universe.

Sukuna: (Laughing Evilly) Just try and stop me and we'll see whose attack is strong-

GODLY DEATH PUNCH!

Then Godfield unleashed one of his most deadly punches that is so powerful, the fist is also the Hand of God itself as Sukuna unlocked his true potential before the punch could land on the demon as Godfield is now in his own domain as he can see Sukuna lounging around in his cloak as his throne is a pile of bones of his many victims.

Godfield is not amused by Sukuna's attempts to defeat him and his son as Sukuna's demonic glowed brightly in the dark in a blood red color.

Godfield: What is this? Are you keeping fooling around with this kind of sorcery? We don't have time to entertain you all the time.

Sukuna: (Thinking) This strange cat is still unaware of his and his son's position. I got them right where I want them.

Godfield: Are you even listening to me? Answer my question or we'll both just leave this strange realm.

Sukuna: Even if you force it, you and your son won't be able to get out of here. You're both in my dimension now. Evil Temple. Just give up and surrender yourselves to me.

Godfield: Not a chance, Sukuna. Evil or good temple, we will just break it all down with a single blow. We are known to devour universe and even God himself and we are both the true Vs. Gorefield. You cannot stop us. You don't have the power to defeat us.

Then Godfield turned to leave, but Sukuna doesn't want them to leave as he is the only one that can control this domain whether or not he will let Y/n and Godfield out of his domain or not.

Sukuna: Just try and leave as you like, if you both give up, come back here.

Godfield: Do not underestimate our divine power. You have no idea on who you are dealing with right now. You don't know anything about us, we have to sacrifice everything to both become a God and we both recreate the world in our universe with the ashes of the old world after it was filled with nothing but corruption and sin as the old world could not be saved.

Sukuna: I see. Both of your strength, your innocence won't help much, but I can understand about you and your son origin story. However, your attempt to leave my world is impossible, this will take forever for you two to leave in such a hurry. Or should I, end it right now.

Godfield: Are you serious right now. You may be a powerful demon, but your attacks have no effect on me or my son. This fight will go on forever, and only one of us will win this fight. Your choice.

Sukuna: I see. Then what is you and your son's true desire. Humans usually want to express their last desires when I gave them their last request before I kill them. But for you two, I can make an exception. What do you both desire most?

Godfield: We both don't want anything that the multiverse has to offer. We pretty much have what we needed...however, there is one wish that is truly impossible for someone like you to grant us as we both have been on a constant search for the Perfect Lasagna. The taste of this divine Italian dish is to die for, and you need the right kind of ingredients to make that dish. You'll never know how good it would taste once you take a bit of that kind of lasagna.

Sukuna: Okay then. I can understand what you're talking about. I will help you...

Godfield: (Chuckling) You're kidding, right? You really think you have what it takes to create the Perfect Lasagna? No. Your demon powers are not enough to make that wish a reality. Only those who are worthy of collecting the rare ingredients to make that Lasagna and you are not worthy.

Then Sukuna unleashed another Cleave attack to slice off Godfield's head, but it didn't harm him as Sukuna's attacks have no effect on him whatsoever.

Sukuna: Well then. If that's the case, then I will destroy all of the Lasagna in Italy for those selected people.

Godfield: You will do nothing.

Then Sukuna jumped out of his throne and landed in front of Godfield as the Cat God has had enough of this demon.

Godfield: I had enough of this nonsense from you, Sukuna. I have no choice but to kill you myself.

Sukuna: (Smiles Evilly) Just try to beat me, if you can.

Godfield: Very well...

Then Godfield performed the same hand pose to activate his own domain expansion that will be powerful enough to finally kill Sukuna once and for all.

Godfield: You do this to form your dimension right?

Then suddenly, Sukuna's domain was changed into a whole new world as everything became a mountain area as Sukuna looked around to find himself in Godfield's own dimension.

Sukuna: Quite troublesome. How could you...

Then without warning, Sukuna was pulled into the air and was instantly nailed to a golden cross as Sukuna suddenly felt a massive jolt of pain all over his body as he is starting to feel weaker by the minute.

Sukuna: (Pained Scream) Why does this hurt so much?! GAAAAAAAAHH!!!

Godfield: Domain Expansion: Wrath of Godfield

Then as Godfield sunk into the ground, he rose up from the ground as he transformed into the same from the created the new world as Ophiuchus Gorefield as Sukuna has messed up big time as he is now about to face the wrath of Godfield.

Godfield: Repent your sins, Sukuna. You lost.

Then with a powerful burst of Energy, Godfield unleashed a beam of pure holy energy into the night sky before a meteor shower of energy balls rained upon the domain with Sukuna soon got obliterated by Godfield's godly wrath, as the world was destroyed thus finally killing the demon and freeing the teen that was possessed by the demon himself, Itadori.

Sukuna: (Death Scream)

With that, the nightmare is finally over and Itadori is finally free from Sukuna's control.

Itadori: (Weakly) Am I....really free from him?

Y/n: Yes, my friend. You are safe from Sukuna. The nightmare is over.

Itadori: Damn...finally...it's over... (Passes out)

Y/n: (Sighs) Finally. Now I can go home and rest.

???: Meow!

Y/n: Huh? (Looks down to see a Garfield Angel) Oh hey little one. What are you doing here?

Then the Garfield Angel hands Y/n the weird cube with the eyes as Y/n is surprised to see something like the cube with eyes that the cat angel stole from that man from the train station.

Y/n: What the heck is this thing? It looks really strange looking. I wonder if- (Accidentally squeezes it too hard) Oops!

Garfield Angel: (Shocked!) GAH!

Y/n: Oh geez! I hope the owner of this strange cube doesn't find out about this! Let's get out of here!

Then Y/n opened a portal back to their own world as they both immediately back home, not realizing what the cube really is and who was trapped in the cube as Y/n will meet a somewhat familiar face from the train station in the next chapter.
