Sukuna's Debut

"Looks like you roughed up my sister pretty bad" Goro said with a smirk. "While you two were having fun in your Domains, I was busy recovering from that injury I sustained" He said. 'Damn it. I completely forgot about this guy' Yujiro thought to himself. Goro's sister jumped away from her position and next to her brother. Yujiro was about to face a tag team that was even stronger than the triple threat. "I went easy on you because you were my underclassmen...but dont expect the same NEXT TIME!" Goro said with a smile as he suddenly disappeared.

A fist came crashing in Yujiro's face which sent him flying into the arena wall. 'He's so fast, I couldn't even register his movements. Damn it!' he thought. Before Yujiro could get out the wall, he took a knee to the stomach which made him cough a bit of blood. "You know, I didn't think you'd have enough power to fracture my spine. If I hadn't been healed by that other guys cursed energy, I would have been paralyzed the whole round. Unlucky for you I guess" Goro said while walking away.

Yujiro launched off the wall in an attempt to get ahold of Goro and choke him out from behind, but Goro dodged while grabbing Yujiro's leg mid-air and throwing him back at the wall. "I didn't say you could leave" Goro said seriously.

(Flashback)

"How about it first year, do you accept my challenge?" Goro said. "What do I get if I win" Yujiro asked. Everyone else started laughing at that question like it was Joke. "Bold of you to assume that you will win, but if there is the slightest chance you do win, I will personally pay you 5 Million Dollars cash" Goro said boldy. 'With that much money, I could pay for my sisters hospital bills' Yujiro thought to himself. "but IF I WIN, then that cute little sister you've been hiding from us will belong to me" Goro said will a evil grin. 'Even if he's strong, he'll probably underestimate from the start of the battle. I can use that as my chance to quickly finish him off' Yujiro thought. "I....I accept" He said. "Good"

(Flashback End)

'Damn it. Even if he cheated, Even if he worked with the judges that allowed his sister and the others to illegally join our battle, they were all easy prey. But to think they would have a healer on their side, ESPECIALLY IN THIS COUNTRY?'

(AN: Healers are people who can use reverse cursed techniques to heal others, something that only curses could do. And its very rare to find one, almost like a 1 in 50 Million chance)

"Sukuna, please help me" Yujiro whispered. Sukuna started laughing violently. "Kid, you do know what I'll do to those children if you let me take control?" Sukuna said with a evilish smirk. "This isn't the old world your used to sukuna. Its Killed or be killed AND IF I DONT DO THIS, THAT BASTARD WILL HAVE HIS WAYS WITH MY SISTERRR" Yujrio yelled as a cursed aura darker than his original one violently emitted from his body. He had a strange line pattern on his face and it seemingly ran throughout his whole body. Then a dark voice spoke from his mouth. "Thats what I like to hear" Sukuna said with bloodlust.

All the wounds and injuries that covered his body healed in an instant and Sukuna smiled while looking at Goro and the others. "It seems you were hiding your true power as we-" Goro was cut off my the hand the went straight through his heart. He spilled what seemed to be gallons of blood on the floor. Behind him was his horrofied sister who could see the beating heart that sukuna was holding in his hand. "Weak" Sukuna said while taking his hand out of Goro and letting him drop dead.

"YOU FOOL, STOP WATCHING AND USE YOUR CURSED CHAINS" She yelled fearfully. The other guy who was also terrified tried to use the cursed chains but his efforts were fruitless as Sukuna grabbed the chains and sucked all the cursed energy out the poor guy through his own chains. He threw a chain at Goro's sister which was aimed to kill her but someone appeared in front of her and caught the chain. "Oh?" Sukuna said. "That is ENOUGH! This battle is over. You have done more than enough Mr.Itadori. Take the money and leave" The elderly figure said. "Ha Ha Ha, you are lucky girl. You get to live another day" Sukuna said while walking away. The lines on Yujiro's face disappeared and Sukuna returned back to his mental shrine.

"Sigh, I thank you Sukuna" Yujiro said aloud to himself.

(Meanwhile)

"WHAT DO YOU MEAN MY SON IS DEAD!?" Goro yelled. "As I said sir, He died during battle against that...that demon from the Itadori Clan" the servant said. "That IDIOT SON!" He said angrily. "I told that idiot don't mess with the Itadori clan. They may be one of the weaker clans but their clan heads aren't nothing to play with. Not in the slightest, sigh" He said in a sad/mad rage. "Does my daughter still live?" He asked. "Yes sir...what about her?" the servant asked.

"She will be the new next clan head of the Ichigawa clan. Be sure to inform her about the Itadori and please make sure she never makes the same mistake my son did, sigh. Them damn monsters"

(AN: The clan heads of the Itadori clan are the holders of Sukuna. The reason they are so young is because a vessel must give birth to a child before the age of 30 and the when their child is born, Sukuna will migrate to the newborn baby and the old vessel will die. A vessel of Sukuna will live up to 30 years before dying and Sukuna being released so to counter that they have a child that will hold him instead but the old vessel will still die. Yujiro's sister is his twin but because he was born first, he got Sukuna instead of her)
