He didn’t regret his decision. To wander alone and help society by getting rid of curses. However, how could one truly be along if someone else occupied their body? After all, Sukuna wasn’t one to sit back and just let stuff happen to him.
Yuuji only regretted agreeing to that vow to let the curse to attempt to assimilate himself better into the body. Instead of a get along shirt or a parasite, it was like operating in unison. A perfect symphony that was played by medium rated players. Perfect but sometimes riddled with mistakes.
Years had passed since a routine had been established. Killing curses and protecting his fellow man and Jujutsu sorcerers was the only goals since his “failed” execution.
It was after only he forgot how many bodies and souls he killed, did Yuuji truly looked at himself in the mirror. It had been a while since he stepped foot inside the school. The wards were worn down enough for him to enter again.
Standing in his room stood a long body mirror.
All he had seen of himself since his friends’ death was Sukuna. Yuuji had his markings. His eyes gained a reddish hue. Nails grew longer and darker in color. An appetite of raw bloodied meat, both curse and human, had grown from being manageable to insatiable. Yuuji couldn’t help if everyone who stood in his way became victim to his urges. They were dead the second they crossed him. Sliced up into perfect bites.
He couldn’t tell who or what he was anymore.
Looking at the mirror, Yuuji saw the monster that resided in his body. Anger and frustration grew until he punch at his reflection, cracking the glass, leaving blood drops on it. He cradled his torn and bloodied fist while he heard Sukuna’s laughter in the background of his mind.
“Shut up!”, Yuuji yelled. The noise was making him feel crazy and boxed in. It was too loud. And almost as if Sukuna could read his thoughts(which he absolutely could), the laughter lessened but was not completely gone.
“You honestly can’t blame me for what you’ve become.”
“Oh, really?”, Yuuji asked in a tone of disbelief. “Because we can’t forget about what happened in Shibuya, Gojo, the fucking trial. You killed everyone. That was all on you. You helped make me this way.”
“True.”, the curse reluctantly conceded. “But,” Sukuna began and Yuuji could almost see the smirk on his face. “I didn’t make you do anything after that. I’ve merely suggested things. I “behaved” while I was in this body.”
Despite what Yuuji felt about what the curse was saying, he knew Sukuna had a point. Everything after the vow was entirely on him. Those deaths, the destruction that followed his path, everyone leaving, that was all him.
“So take another look inside that mirror again.” Sukuna’s voice felt like a whisper in his ear. “What’s reflected back, brat?”
Yuuji looked again at the cracked mirror in front of him. This time, instead of seeing Sukuna in his reflection, he saw himself.
