GoJaku

"Good night, Satoru Gojo. Let us meet again in the new world."

- Chapter 91

GoJaku is the slash ship between Satoru Gojo and Kenjaku from the Jujutsu Kaisen fandom.

Canon
Kenjaku is an ancient sorcerer, but despite being very powerful, Kenjaku has a weakness – sorcerers with the Six Eyes technique who are powerful enough to stop him. In the past, Kenjaku met several and never managed to overcome any of them. In the modern age, Kenjaku has found a way around that problem. In order to immobilize Satoru Gojo, the strongest sorcerer alive and the bearer of the Six Eyes, and render him unable to fight, Kenjaku steal the body of Gojo’s old friend and takes possession of it. Being able to access Suguru Geto’s memories and see Gojo’s strongest and weakest points, Kenkaju carefully works out a masterful plan how to defeat Gojo and calculates all the details. During the first arcs of the series Kenjaku avoids being seen by Gojo because it would foil his plan to defeat Gojo which relies on surprising him.

Shibuya Incident Arc
On October 31st, Kenjaku and his group arrive at Shibuya station. The sorcerer himself hides and waits. He watches his accomplices Jogo, Hanami, and Choso fight invincible Gojo. Kenjaku knows that it’s not easy to defeat Gojo and make him less focused than he usually is, so the long fight is meant to wear him off. Kenjaku is knowledgeable enough to understand that it will not be enough, so they have to get him on edge more – so he makes him kill a thousand of mutated people.

Right after Gojo casts his Infinite Void and destroyed the crowd of transfigured people, he finds a box in front of him. Kenjaku calls him by his first name from behind. Perplexed Gojo sees the face of his dead friend and freezes. As the memories of his youth flood his brain, a minute passes, and Gojo is seized. Kenjaku mocks him for getting distracted during a fight. Gojo is angered, he asks Kenjaku who he really is, but the ancient sorcerer is keeping the pretense of being Geto. It enrages Gojo even more and he lets himself scream at the opponent. Kenjaku unseals his stitches and shows him the inside of his head whilst explaining the situation and his technique that allows him to hop between bodies.

Kenjaku says that Gojo will be unsealed one day, maybe in a hundred or a thousand years. He adds that Gojo was getting in the way of his plans and now he will have to wait patiently. Pseudo-Geto believes that Gojo is not only the strongest sorcerer, but his students won’t be able to match his power, even another special grade sorcerer Yuta Okkotsu. The sorcerer bids Gojo goodnight and says he hopes they’ll meet again in the new world. When Mahito joins their conversation, Gojo begs to be sealed right away because he takes no joy in looking at the two. Kenjaku says that he, on contrary, is pleased with the view in front of him – Gojo defeated on his knees, and thus, he seals the Prison Realm. After that Kenjaku tries to leave with the cube, but Gojo makes it slam on the ground before Prison Realm finished processing its catch. The sorcerer stays to guard the cube until the process is complete. Afterwards he carries the cube with him.

Culling Game Arc
As Gojo is unsealed, he teleports right in front of Kenjaku and threatens him. Kenjaku reveals he left the front of the Prison Realm at the bottom of the Japan trench 8,000 meters underwater within multiple layers of seals to stop Gojo from escaping. As Gojo is about to kill Kenjaku, Sukuna appears to challenge him. Kenjaku, scared of Gojo, hides behind Sukuna and halts the fight. Gojo makes fun of Sukuna for listening to Kenjaku but notes that the two may have a binding vow with each other. Gojo proposes to postpone the fight until December 24th, which Kenjaku calls romantic. Gojo says it would be annoying to have two death anniversaries, to which Kenjaku asks him if he beleives he can win and Gojo responds by declaring his victory against Sukuna.

Shinjuku Showdown Arc
During the month between Gojo's release and his fight with Sukuna, Kenjaku stays close to Sukuna because he is afraid Gojo will kill him. Later, Kenjaku watches Gojo's death through his phone and comments on the technique Sukuna used to kill him.

Fanon
is not a big ship, but fan arts depicting Gojo and Kenjaku in the body of Suguru Geto are very common. One of the Japanese names for the ship is 脳五, which translates to "brain" and "five". The shipping of the pairing mainly stems from SatoSugu and its implications. Many Gojo/Kenjaku centered fan works are not tagged with Kenjaku's name, since his trues identity was only revealed in chapter 90, and before that fans believed it was the real "Geto", so they keep using his old name.

Before Kenjaku started inhabiting the body of Suguru Geto, he possessed the body of a woman who gave birth to Yuji Itadori, which makes him the boy's mother. Given that Gojo played the mentor role or, as others say, was a parental figure in Yuji’s life after the death of his grandfather, Jujutsu Kaisen fans started joking about their “dysfunctional family” (like in this humorous comic). In memes Kenjaku is often depicted as Yuji’s strict mother and Gojo – as Yuji’s carefree father-in-law.

Trivia

 * Prison Realm that Gojo is contained within has a "front gate" that, after his consealmant, got multiple pairs of eyes all over its facets (alludes to Gojo’s Six Eyes technique); and it has a "back gate" — a facet with a stitched wound, just like the one Kenjaku has on his forehead.
