GojoKima

GojoKima is the het ship between Makima and Satoru Gojo from the Jujutsu Kaisen and Chainsaw Man fandoms.

Canon
There is no canon information on GojoKima since they do not exist within the same universe or timeline.

Gojo and Makima both serve as high-ranking authority figures to their respective demon-hunting organizations; Gojo is a teacher at Jujutsu High and Makima leads a division of Public Safety Devil Hunters. They both took the main protagonists under their wing and act as the main trios' mentors.

They both are the most powerful characters in their home series, and because of that enemies tend to be terrified of them. Both their allies dislike them for various reasons; Gojol loves to mess with people, while Makima is wrapped in a lot of mysteries. The two can manipulate space in some way: for example, Gojo's Cursed Technique grants him absolute control over space with an area while Makima can crush her enemies with an invisible force. The two possess hypnotizing, powerful eyes as well and are often depicted wearing dark clothing.

Beneath their facade, they can be absolutely ruthless; Gojo personally decapitated a Cursed Being with his bare hands while Makima showed Yakuza members a bag of their loved ones' eyes to get them to work with her. Both see themselves as superior to everyone else and could back it up with their immense power.

Fanon
Gojo and Makima are often paired because of their similarities. Some GojoKima fanwork portray them hanging out along with their proteges or the two shopping for plushies or eating together.

Another reason is their opposite dynamic: while Gojo is laid-back and playful, Makima is stoic and composed. Them being polar opposites in terms of morality (Gojo being the benevolent mentor his students and Makima being the manipulative villain of Part 1) has led some to portray GojoKima as an 'enemies with benefits'-type relationship. Some fan art features outfit and setting swaps, etc where Gojo is the Control Devil and Makima is a Jujutsu sorcerer.

GojoKima is relatively unpopular due to both characters being in different series so there isn't much art or writing about them. Those that exists are either fanmade fights between the two or romantic AUs.
