Qi Mu Kongsu, IQ 218, a bona fide supergenius. In his eyes, all humans are a bunch of unevolved monkeys, except for his younger brother.
Suguru Geto was hailed as one of the strongest in Jujutsu Society alongside his best friend, Satoru Gojo. He later defected and became a Curse User, believing that everyone who wasn't a Jujutsu Sorcerer was a monkey.
Qi Mu Kusuo, an esper who can do almost anything, accidentally let his powers slip while asleep one day, transporting his older brother Qi Mu Kongsu to the world of Jujutsu Kaisen.
And so, the genius scientist met 17-year-old Geto, a student at Jujutsu High.
Qi Mu Kongsu: "This world without Kusuo is so boring. And these annoying monkeys, too. Maybe I should destroy a world for fun."
Geto, who has always believed ordinary people are weak and need protection: "???"
Qi Mu Kongsu noticed Suguru Geto staring at him and clicked his tongue impatiently. "What are you looking at, monkey?"
Geto, wearing a fake smile: "Just looking at a monkey. What's wrong? Are you going to charge me an admission fee?" What an obnoxious little chuunibyou.

Years later.
The defected cult leader Geto: "Submit to me, monkeys!"
Qi Mu Kongsu, who has decided to kill all the monkeys and destroy the world: Submit? Is he the king of the monkeys?
That's it. I'll kill him first. To catch the bandit, capture the ringleader.
Cult leader Geto: "?"

After making an example of one monkey to scare the rest, cult leader Geto returned to his room and recalled some nauseating memories. He couldn't help murmuring, "I'll kill every last one of those uncivilized monkeys." Then I'll create a world with only Jujutsu Sorcerers!
Qi Mu Kongsu, hidden in the dark corner of the room with a laser gun and about to take him out, was stunned. He lowered his gun. "That's exactly what I was thinking. Then let's start with you." He hadn't expected this monkey to be so cooperative. He wouldn't even have to do the dirty work himself.
