Yuji Itadori and his twin brother were born to the Itadori Family, Kaori Itadori and Jin Itadori are their biological parents. One twin, Yuji, he was born perfectly normal and fine but the other twin was born with 4 arms, 4 eyes, and 2 mouths. This was caused because Kaori starved when being pregnant with the twins, that was actually supposed to be triplets but for unconscious desperation of survival, the abnormal twin ate the 3rd twin which caused him to merge of the twin and be born looking like a monster. He wasn’t even given a name because of how horrifying he appeared to be. Growing up was even worst because the abnormal twin got abused and neglected everyday by not just his family but even outsiders—Yuji was loved and treasured by everyone. The monstrous twin didn’t rebel against Yuji though because Yuji favorited him and was the only one to love him so dearly. And throughout time, the abnormal twin gave himself a non-legal name; calling himself Ryomen Sukuna, naming himself after an evil figure from a Japanese folklore.

Sukuna and Yuji are 15 years old now, both tied to chairs in a room. A blindfolded man speaks.

Gojo: “Good morning…”

Gojo sits across from them, smirking. Sukuna and Yuji woke up. Once Sukuna gained consciousness, he glared at Gojo. Yuji notices talismans around the room but is too tired to think.

Gojo: “So, you’re the odd twins?”

Sukuna: “Who the hell are you?”

Gojo: “Satoru Gojo, head of first-years at Jujutsu High.”

Yuji lifts his head. Yuji struggles against his restraints. Sukuna was also restrained but he had talismans around him so he couldn’t use his cursed energy.

Yuji: “Jujutsu…? What is this…?”

Gojo: “Apologies. You’re tied down because we just don’t know what to expect from you twins.”

Sukuna glares harder. Gojo explains the situation, recapping how Yuji and Sukuna got into that disaster from Yuji trying to save his friends, Sukuna nearly burned down the building from going all out on that curse that tried to kill Yuji and Yuji’s friends.

Gojo: “Afterwards one of you guys strength was extremely noticeable to the Higher Ups—they decided it’s too risky to let you both run off in the public. Especially because we don’t know which twin it was. The Higher Ups did want to execute you both but after some negotiations, I made a deal with them to give you both a chance and become students at Jujutsu High. You’d be under my observation and as my students.”

Gojo observed them closely, he had his expectations placed for them about what it was gonna be like mentoring them.

He also was interested in them both because the one on the right looks like a cursed spirit while the other one looks like a human. All the information Gojo’s Six Eyes provided to him tells him that Sukuna isn’t a cursed spirit but is just as human as Yuji. He figures Sukuna must have a serve birth defect if he has 4 arms and 2 faces.

Gojo was also a little amused at the amount of Cursed Energy he can see around Sukuna, it’s no question that Sukuna is the threatening twin while Yuji is the innocent one. His smirk didn’t falter.

Gojo: “In shorter terms, it’s either execution or you both come to Jujutsu High as students.”
