{Chapter 6}

Third Pov

After the transpiring events of having his heart ripped from his body. Yuji found himself standing in a place that was littered with nothing but various bones and blood colored water. Staring at the malevolent king in seething anger, as he sat on his throne of skulls.

Sukuna:"*smirk* Heh, don't look inside me without permission you brat"

Yuji:"*smirk* Then come down from there, and I'll look down on you!"

Sukuna:"Your being awfully hostile, aren't you?"

Yuji:"Damn straight I am. You killed me! And even worse you molested (y/n)!"

Sukuna:"This is the thanks I get for fixing your arm?"

Yuji:"Yeah, and you also ripped out my heart right after that!—Is this hell?...I'm not sure I can accept being stuck with you even after death. This works out, though. I'll make you cry!"

{Skipping minor fight}

Despite all the blows he threw at him, Yuji ultimately ended up laying face first into the water. Being nothing more than a seat cushion for the king.

Sukuna:"This isn't the afterlife. It's my innate domain"

Yuji:"Innate domain? The thing fushiguro talked about?"

Sukuna:"You could also say were in my mind. In other words, we're not dead yet. If you'll accept my conditions, I'll fix your heart and bring us back to life"

Yuji:"Cocky bastard. You act all big, but I know you don't want to die, either"

Sukuna:"*smile* The situation's changed. In the near future, I'll be able to see something interesting"

Sukuna exclaimed as images of Megumi and (Y/n) appeared in his thoughts.

Sukuna:"Still...It honestly annoys me that woman chose to reincarnate into that damned clan"

Yuji:"Huh!? What women?"

Sukuna:"*smirk* Nothing you need to worry about for now. Anyways, I have two conditions. One: when I chant "Extension," you'll hand over your body for one minute. Two: You'll forget this promise"

Yuji:"No way! I don't know what your after but it's shady as hell. I finally get what your really about now, your pure evil. I'm not lending you my body or letting you touch my sister ever again!"

Sukuna:"*sigh* Really, your still calling that girl your sister"

Yuji:"Of course I am! Even though we aren't blood related I still consider (y/n) family"

Sukuna:"*smirk* Just saying for someone who you call your sister, you sure have a lot of  "interesting" thoughts that say otherwise"

Yuji couldn't help but blush in realization at Sukuna's words. It's true despite being raised together as siblings, he did harbor feelings for (y/n) that were more than familia love. If his heart didn't convince him, then the unsavory ways he imagined her definitely did.

Sukuna:"Now back to the matter, during that minute I promise I won't kill or injure anyone. *sigh* so annoying"

Yuji:"Like I can believe you!"

Sukuna:"It's not about whether you believe me or not. This is a pact, a geas. I'll be the one punished if I break it. If you pursue selfish gain beyond your means, you'll earn retribution. I'm pretty sure you've experienced that for yourself"

Yuji:"Well it wasn't impossible before!"

Sukuna:"Huh?...Oh...that time I wanted to switch too, and you were just doing what your sorcerer told you to. A pact found by mutual interest, that's one of the key factors behind all jujutsu"
