I Took My Custom Techniques to Jujutsu Kaisen for Some Fun

【Jujutsu Kaisen + Cursed Technique Roulette + chaos-loving troll + pseudo-simulation】 Bai Niaowu, a bloodthirsty Jujutsu Kaisen fan who loves stirring up trouble, spends every night staying up late and fighting with people on the Jujutsu Kaisen forums, posting increasingly unhinged takes. One day, sleep deprivation leaves him dazed. He slips while going to the bathroom, gets his head stuck in the toilet, and suffocates to death. But that sends him transmigrating into the world of Jujutsu Kaisen, where he binds himself to the Sukuna Challenge System and gains the golden finger of being able to customize cursed techniques. As long as he writes a cursed technique with sufficiently consistent logic and a well-developed design, he can take it with him when he transmigrates into the Jujutsu Kaisen world and take part in the story himself. “Sure, spending two minutes writing an overpowered technique that instantly kills everyone is satisfying, but that's... the thinking of a loser!” So says Bai Niaowu. “Taking a technique with pathetic attack power but a slightly outrageous, thunderous gimmick and using it to mess with Sukuna's face? Now that's how a strong person thinks!” System: You might have a screw loose. Bai Niaowu: Really... Yeah! I really do! System: LOL
