From the beginning of Jujutsu Kaisen, very little is shown about Yuji Itadori’s originbecause it is only known that he is a boy who lost his parents and was left in the custody of his grandfather Wasuke Itadoriwho was responsible for raising him and guiding him on a good path until he died leaving only one mission for Yuji, “help people and be loved by them so I don’t end up like him”.
since then no one talks about other relatives by Yuji Itadori, although it seems that the protagonist comes from a much more powerful lineage than previously thought, and this leads to a dark story that involves his mother, who would be linked to Jujutsu after giving birth. Next, we explain the secret that hides the Itadori family and the reason why Yuji has been able to stand out among the shamans of the Tokyo Metropolitan School (SPOILERS).
The truth about Yuji Itadori’s family in Jujutsu Kaisen
In the Jujutsu Kaisen manga chapter 143 A flashback occurs in which we can see a man named Jin arguing with Wasuke Itadori, who would be father and son. Jin Itadori has always remained a human with no special abilities, since his only dream was to become a father and finally he could be by having Yuji Itadori with his second wife, since he couldn’t have him with Kaori due to her tragic death.
Wasuke convinced that having a child with this second wife implies a bad omen, and tells Jin, but he continues to adore his son in the face of anything. As Kaori’s death is about to be revealed, a girl arrives with a scar on the forehead representing Kenjaku himself, the “Worst Shaman in History”. This would be the same villain we know as Suguro Geto, only by then he had been able to possess said mysterious woman to perform an experiment with the aim of create hybrids from a human cursethus being the possible origin of what we know as “Cursed Uterus”.
It is here that something shocking about Yuji is discovered, and to understand it better we have to move to the Meiji era (between 1868-1912)a time when Noritoshi Kamo had found a girl capable of getting pregnant with curses, and to save the children, he executed the creation of three cursed wombs, which would contain the “Three Cursed Brothers”, Choso, Esou and Kechizu. Therefore, Yuji Itadori is probably a fourth child fathered by the cursed womb technique, and this is why he could consider said special curses as their own half-siblingseven Choso knows the story and tries to maintain a bond of brotherhood with him.
As for the functioning of the cursed womb, It is done by means of a cursed object, such as Sukuna’s Fingers. The uterus is going to be in charge of extracting all the cursed energy to start creating a curse as a result of it until it is ready to be given birth. If we think about it this way, it would not be crazy to say that in a few words Yuji Itadori would be the son of Jin Itadori and the woman possessed by Kenjakuwhile Choso, Esou and Kechizu would be his closest relatives today.
Surely this it would explain many things about Yujistarting with being strong enough to hold off the King of Curses, Sukuna, and also showing much higher physical strength than that of the average human.
