Rengoku x Reader x Sukuna PAUSED

Sword Play

Afternoon clocked in. Shinjuro and you stood outside watching Rengoku train Senjurō.

"You won't tell me will you?"

His question caught you off guard as he kept his eyes forward.

"My son is not the same. I see it.." Shinjuro watched Rengoku stand before the bamboo cutting stance.

Reaching to his side for his sword, Rengokus smile held the energetic flame that was needing to burst out. This overwhelming amount of power. This confidence that he didn't possess before.

"This feeling," Rengoku thought as he quickly withdrew his sword cleanly slicing through 1st to 2nd bottom, 3rd half top and 4th bottom cut.

Is the feeling of being one with Sukuna.

Your eyes could see the demon side of Rengoku. Sukuna was not only becoming one with Rengoku!

Sukuna was fathering Rengokus talents.

Shinjuro was left speechless as his face quickly turned to disapproval.

The flame he saw burst had a new spark to it. Rengoku had shown something remarkable with his cutting technique and form. Not just that but his closing expression was perfect!

That's the thing..

It was a technique that was remarkably close to a demon's technique.

That cutting stance, if it were to have been a demon Rengoku had already cut every heart.

"Rengoku!" Shinjuro shouted, grasping the wooden sword from Senjurō who ran to your side, nervous.

"Father. Why are you upset with my brother?"

Standing before his son, you watched Shinjuro take his stance. "I'll be the one to decide if the person standing before me is my son.

Or a demon."

Relaxing his shoulders holding the wooden sword before him. Eyes locked into his son's who accepted this. Sukuna, relaxed Rengokus body resembling the tranquility of a samurai.

Rengokus' eyes opened as an energy of flames bursted from him. Sukuna looked down at Shinjuro knowing this is nothing more but a broken spirit.

It wouldn't bother him to help Rengoku cut his father down; a couple noches.

The winds picked up blowing through Rengokus hair and Shinjuros made Sukuna look naturally to you.

Your head was down glaring at him from beneath your eyelids. That void surrounded you and him as his entire spirit domain was being devoured.

You were trying to conceal Sukuna. Trying to prevent him from assisting Rengoku.

Sukuna turned his attention to the ribs above him that were being devoured.

Damn .. you are terrifying...

Sighing he rested his chin on his knuckles before fading away deeper into Rengokus consciousness.

Once he had left Rengoku to defend himself, your void retreated back to you. It won't be Rengokus fault if he beats his father.

It's gonna be Sukunas fault...

You don't want Sukuna to expose himself and put precious Rengoku in danger.

Rengoku looked at him, feeling Sukuna retreat.

"Fight your own battles, boy."

You are the reason why he can't help humans out in general.

Some rule you made up that he shouldn't look down on them. Everything a human gains is gained by their own struggle.

Itadori, was an example of Sukunas boundaries of battle assistance.

Itadori had faced his challenges with little to no assistance from Sukuna. But Itadori grew without Sukuna.

Rengoku stepped forward, clashing his sword with Shinjuros wooden sword. Leaning in, Shinjuro elbows his son, making his neck fly back with blood pouring out of his nose.

Sukuna watched from his throne, seeing a father holding zero fucks!

His eyes rolled up to look up at the ribs smiling.

Standing up arms wide open he changed his domain to have a more purple tone.

Flowers of different sorts grew around his corpses.

"Welcome!" He shouted with a wide smile as you stepped into his soul.

Rengoku threw his head forward, eyes wide with spark and a smile that never faded. Even without Sukuna you were here!

Shinjuro pushed back his son brutally attacking him to take the sword away from Rengoku.

Rengoku now had the wooden sword in his possession while his father had the real thing. "Father, you wouldn't kill Kyojuro!" Senjurō wanted to interfere but your hand rested on his shoulder.

There was something cold and dead behind that smile. There was no soul or warmth behind your eyes. Senjurō looked away quickly in fear. "I'm sorry.. I didn't mean.." you looked away, focusing again.

What Senjurō saw was a body with no soul. It moved because you instinctively moved.

When you are visiting or touching someone else's soul your body is left wandering around. Rengoku saw this when you tried to leave.

You weren't in your body. He knew since he brought you here. That you were visiting Sukuna. Even when his body was trapped in a finger you could hear his voice in the void.

Certain reflexes can be triggered but only to defend yourself. Yet, Senjurō had awoken your body's reflexes. Feeling not danger for itself but it felt that Senjurō was in danger and acted in response.

"You love humans too much. Y/n, do you think Shinjuro will forgive you? There won't be mercy for you. All the mercy and forgiveness you give them they share none for you. They share none for me.

We don't need it. They live and fade away from our world. We continue..."

Shinjuro, kneeed Rengokus rjbs. Rengoku gripped the handle of his sword, forcing himself to endure and move forward.

"You enjoy watching them suffer when you know we could easily unlock their full potential. Even with this man you don't seem to be easy on him.

Do you enjoy watching him suffer?"

You smiled, shaking your head before stepping away from your soul.

"Y/n!" He watched his world turn back to the violent red of blood and bodies.
