Monster Vs. Machine.

In a deep forest located in Kyoto Prefecture, three figures could be seen jumping through the trees.

"Tch. Oi, how much longer, Mahito?"

They had been jumping through this forest for about ten minutes now and Naoya was starting to get annoyed at that fact. Since the Zenin Clan massacre, he was itching to get into a fight.

After all, even though he had joined Jin for a little while now, this was the first time they actually went on a mission together.

He was eager to prove himself worthy of being apart of the curse user group.

"Patience now~. We're almost there."

Just as Mahito said, not long after he said that, they suddenly jumped down to a cave blocked by two large metal double doors.

"Here we are. The location the boy sent."

As the three approached the doors, they opened automatically. Surprisingly enough, Jin didn't sense any hidden sorcerers around them.

Seems like the traitor was at least being marginally honest.

Several seconds of walking later, the three happened upon a big opening within the cave with metal cables hung all across the ceiling and a horrid stench emanating from a container in the middle of it.

Within that container was a person covered in bandages sitting in what seemed to be a vat of blood.

"You're here. Hm? You brought two interesting people, Mahito. Care to tell me why?"

The three walked up to the person in the container and in response, numerous puppets emerged behind him.

"Take it easy, man. These guys work with us. They were just interested in the information you gave us."

Jin could see how on edge the boy beneath the bandages was. His flickering eyes showed everything.

"Don't try to pull anything, Mahito. Fulfill your part of the binding vow."

Mahito clicked his tongue, glanced at Jin, and just laid his hands upon the boy, causing his body to glow in a bright light.

Within moments, the bandages came off and the boys body was healed, causing him to stand up within the container.

'That boy was under a heavenly restriction. To think his price was a useless body. Compared to Toji's, it is infinitely worse.'

The Six Eyes revealed everything to Jin. Every day the decision to copy them from Gojo paid off.

*clap* *clap*

"Well, now that the binding vow is fulfilled...we can start the main event."

Since he had already revealed the information, the now healed boy put on some clothes he had nearby and turned his attention to the trio, his puppets guarding him closely.

"You're right, Mahito. We do have some business to settle."

The atmosphere became tense as soon as the boy finished speaking.

Cursed energy began to flow over everyone there, signaling their desire to fight.

"Stay back, you two. I will deal with him."

Jin stepped through Mahito and Naoya as he walked towards the boy standing against them.

With every step, Jin began to reveal the true nature of his cursed energy, causing the boy's body to involuntarily shake when he felt it.

'Who is that?! Such dense and evil cursed energy...I need to act, now!"

BOOM!

The ground burst open as the boy made a quick hand sign, the impact launching the trio of curse users away. Of course, they all recovered quickly, but what was revealed in front of their eyes surprised them all.

A colossal mechanical robot that resembled the ones that were just guarding the boy, just at a much grander scale.

As the boy sat in the machine, piloting it, his eyes were locked on the trio, especially Jin.

"If it was just Mahito and Geto, I think I could win...but against that guy...who the hell is he?! Five years of cursed energy!"

Jin, seeing the robot starting to attack with cursed energy building up from its arms, smiled. The sky seemed to become filled with red lights as the robot shot the energy at them.

Seeing this, he knew that this would be a good battle.

"Oi Jin! Let me fight this guy!"

BZZT! BOOM!

Naoya wanted to step forward, but Jin suddenly erupted into what seemed to be a god of lightning, blowing Naoya away.

Red lightning bolts struck randomly all around him from the sky.

His body was covered in raw crimson ionic energy, causing his surroundings to become ablaze from the blistering heat energy.

"Stand back, you two. Naoya...I'll let you have the next one. This one is mine."

BOOM!

A giant spear of red lightning formed in Jin's palms as he stepped forward and threw it at the machine with incredible force, causing lightning to arc through the forest endlessly.

In response to the lasers, Jin moved into the air towards them, covered in a beam of lightning as he did.

WHOOSH! WHOOSH! BOOM! WHOOSH! BZZT!

A plethora of sounds rang out as the air became covered in a light show of explosions and lightning arcs. With Jin's overwhelming speed, he just couldn't be touched.

Likewise, the robot handily dodged Jin's lightning spear and rushed at him instantly, covering the distance between them in a flash.

"It's faster than I thought. But..."

The lightning spear that had missed the robot suddenly shattered into an innumerable amount of smaller spears and turned around, homing in on the machine.

"That level of speed is not enough."

The robot ran through the forest with incredible agility and dexterity, trying it's best to dodge the spears.

"Be crushed!"

Using his cursed speech, Jin caused an area of immense gravity to form over the robot, pushing it into the ground like a ragdoll.

BOOM! BOOM! BOOM!

Of course, the moment the machine became stationary, the spears struck it immediately, peppering it with damage.

BZZT!

As if he was teleporting, Jin suddenly appeared over the body of the machine and conjured a gigantic lightning spear in his hands. Even the weather started changing due to this attack.

"Hm. He probably used his entire life's worth of cursed energy to operate this robot. It doesn't seem natural. And of course, it is concentrated in the head. Meaning that the boy is piloting it from there. Tch. This is too easy."

Jin crushed his lightning spear within his palms, canceled the gravity zone holding the machine down and landed on it's body, putting his hands in his pockets.

As he looked the machine in the eyes, he said calmly, "Is that all you have, boy? I just gave you a chance to try again. Don't waste it."

BOOM!

The machine instantly sprang up, throwing Jin off of it.

"AARGGHH!!"

It let out a shout of rage as it punched Jin with all its might, even uprooting the surrounding trees from the force.

BOOM!

Jin responded in kind and met the machines' strike with his own fist, causing a shockwave to emerge from the clash.

But they weren't done.

The two started clashing fists over and over, leveling the surroundings around them as they did.

"His cursed energy reinforcement is insane! To think he can still keep up! Ten years of cursed energy!"

Using a feint, the struck at Jin and opened its fist at the last moment, capturing Jin within.

"Oh...it caught me. What next?"

A gigantic red orb of cursed energy emerged from the machines chest, causing a significant part of the forest to become covered in red light.

"Die!"

BOOOMMMM!

The machines eyes shone a sinister light as it let Jin go at the last moment, blasting the curse user with all of its crimson power.

After the giant red laser had dissipated, there was a large ravine in the ground sizzling with heat and flames.

"Hah...I defeated him! Somehow. Now for Mahito-"

BOOM!

Suddenly, Jin appeared, shirtless and mildly bruised, drop kicking the machine in the face as he did.

The robot was sent flying back and managed to recover after a short while, only to feel a incredible force pulling at the metal cords that were coming out of its head.

"What the-"

Before the boy could even react, Jin had appeared behind him and grabbed the metal cords, lifting the entire robot up in the air.

What made this feat even more impressive is that Jin was still in the air as he did this.

BOOM! BOOM! BOOM!

Jin slammed the machine into the ground with all his might and started stomping on it's head with both feet, destroying it with vicious brutality.

BOOM!

Delivering one last stomp, Jin reached through the sheared metal, grabbed the boy out of it and held him by the neck, a small smirk emerging upon his face as he did so.

"It's over, boy. Any final words?"

Struggling for breath as Jin tightened the grip upon his neck with his iron fingers, the boy faintly responded, "M-my...f-friends...will...d-defeat...y-you..."

Jin ignored his foolish threats as a purple aura started enveloping both of them.

"I don't suffer traitors. Your soul is mine."

In a flash, the purple aura entered the boys body through every orifice, causing both bodies to collapse to the ground.

A few seconds later, the boy stood up and opened his eyes, revealing bright orange irises.

Just like that, Jin had taken his body, mind and soul.

But this situation was a bit different from the other times he switched bodies.

Now, his old body wasn't destroyed and it still had the reinforcements that he made during his time within it.

Special grade level physical strength and durability.

How could Jin pass let such a boon pass by?

Crouching down and laying his hand upon his old body, Jin muttered, "Thank you for serving me well."

Immediately after, Jin used his CTR to absorb and fuse with the body, adding its strengths to his own.

The process took only a few seconds as it had no will to resist.

Feeling the immediate increase in strength after, Jin smiled.

"After this, there is only one more body that I'll switch you. Yuji Itadori...my 'son.' Heh."

After cracking his neck a few times, Jin jumped over to Mahito and Naoya in a flash, surprising them both.

"Damn...so you really can change bodies just like that. Man...Ha! It's hard to take you seriously in that new body! The old one was miles better!"

Naoya laughed as Jin approached him, still baffled by the look of the supposed strongest sorcerer alive.

Even Mahito was trying to hide his laughter.

"Yeah, yeah. Whatever, man. Let's head back to Tokyo. Time is ticking and we need to start the plan."
