Gojo Satoru had two best friends. One was a Special Grade Jujutsu Sorcerer, and the other was also a Special Grade Jujutsu Sorcerer. One defected, and so did the other.
Suguru Geto told Gojo Satoru he wanted to create a world inhabited only by jujutsu sorcerers. Then he joined the Star Religious Group and spent all day going, "Monkeys, monkeys, monkeys!"
Sosuke Aizen told Gojo Satoru he wanted to overthrow the jujutsu world. Then he founded Las Noches and said the three of them should stand together in the heavens.
Unable to sleep in the middle of the night, Gojo Satoru thought, "What is wrong with those two? I thought I was the worst-behaved one."
P.S. A joke blurb.
Theme: When did you get the idea that I wasn't using Kyoka Suigetsu?
