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 were found by Satoru Gojo after an incident that Sukuna caused at Sendai school from getting mad over a cursed spirit harming Yuji. They were given the choice of either execution or cooperation so that’s how they ended up as jujutsu high students in the same class as Megumi Fushiguro and Nobara Kugisaki. Sukuna and Yuji wore custom matching school uniforms of where Yuji’s hood and shoes are red but Sukuna’s are blue.

Gojo’s full class; Yuji, Sukuna, Megumi, Nobara, Yuta, Inumaki, Maki, and Panda, all were outside training. Yuji and Sukuna were being given individual lessons by Gojo. Sukuna thought it was pretty damn pointless because he already knew everything Gojo was saying—Gojo knew that too, it’s why he spoke with a small smirk.

Gojo: “Keeping composure in fights will always help more. The more enraged you become, the more cursed energy that can be wasted on your emotions.”

Yuji nods, he was trying to make mental notes of Gojo’s words to remember that. Sukuna already fucking knew it, it’s why he’s pretty composed in battles.

Meanwhile, Megumi was sparring with Maki. Maki, a second-year student, was helping Megumi train his sword skills. Yuta sat with Panda as they watched those 2 go.

Panda: “Maki! Make sure to go gentle!”

Yuta: “Megumi, focus more on offense than defense!”

Yuta gave Megumi a tip after Panda teased Maki. Maki rolled her eyes in annoyance at Panda but Megumi tried to take his senpai’s tip. While they were doing that, Nobara and was sitting with Inumaki. She was ranting to him about how she met an annoying, frustrating Karen the other day. Inumaki listened to her quietly and perfectly well.
