ChosoJaku

ChosoJaku is the family ship between Choso and Kenjaku from the Jujutsu Kaisen fandom.

Meiji Era
Noritoshi Kamo, possessed by Kenjaku, discovered a woman with a special genetic composition allowing her to give birth to a half-human and half-curse child. He forced the woman to have nine pregnancies and nine abortions with a cursed spirit. As stated by Choso himself, Noritoshi Kamo, is in fact his third "parent" due to him having mixed in his own blood into Choso when his mother was pregnant with him. The nine fetuses became nine special grade cursed objects. At some point into the future, Tokyo Jujutsu High was able to secure them into their facilities.

Death Painting Arc
Choso and three of his brothers were taken from Tokyo Jujutsu High by Mahito. They are given bodies by Mahito, under the watchful eye of Kenjaku. Choso and his brothers decide to side with the cursed spirits because Choso thinks it will benefit his brothers more. Later, Choso is playing a board game with Kenjaku and Mahito, when he senses that his brothers have been killed.

Shibuya Incident Arc
On October 31st, Choso is in Shibuya with the Disaster Curses and Kenjaku. After Satoru Gojo is sealed, Choso joins Kenjaku. Kenjaku gives information on the situation and wants to know what Choso and the Disaster Curses will do. Kenjaku choses to stay to watch over the Prison Realm and Choso leaves to find Yuji Itadori.

Choso discovers Yuji is one of his brothers and choses to side with Yuji, against Kenjaku. Choso asks Kenjaku why he made him try and kill his "little brother Yuji". Kenjaku tells Choso not to push himself and says he must be tired. Choso tells him that that is not a reason not to put his life on the line for his little brother. Choso continues to face off against Kenjaku but is stopped by Uraume. Choso is unable to move and watches as Kenjaku activates Idle Transfiguration and as he leaves the battlefield.

Itadori's Extermination Arc
Choso tells Yuji he will continue to call him his "little brother" until Yuji remembers that his father had stitches on his forehead.

Perfect Preparation Arc
The sorcerers arrive at Jujutsu High to talk to Tengen. Tengen tells Choso and the group about Kenjaku, his identity, his plans for the future and the things he has done in the past.

Fanon
is a rareship as it only has 11 works on Archive of our Own. It is Choso's 12th most popular ship, behind ChosoIta and ChosoYuki. It is also Kenjaku's 7th most popular one, behind ships like Mommy Kenny, KenJin or GoJaku. Fans find the relationship interesting because they can understand Choso's point of view, they can understand why he would hold a grudge against Kenjaku for hurting him, his brothers and their mother. Despite their past, Choso is willing to side with Kenjaku if he think that's what is best for his brothers. However, he changed sides when it was revealed Yuji was another one of his brothers and Kenjaku caused the death of his other brothers, Eso and Kechizu, by hiding this information.
