One day, Amamiya Kei watched a Jujutsu Kaisen misunderstanding video. The villain was a handsome white-haired guy, while the protagonist was so hideously deformed that Amamiya wondered if the author had some kind of strange fetish.
But as a good socialist young man, no matter how handsome the world-destroying villain was, he still had to condemn him!
Amamiya Kei had barely finished making his brave declaration when he transmigrated, having only watched a compilation video.
Amamiya: ...Does it really have to be that casual?!
Anyway, as long as he was alive, that was what mattered. The System told him that to stay alive, he had to make sure the good guys won. So he opposed the villainous Big Boss, Gojo-sensei, every day, doing everything he could to make trouble for him.
Including, but not limited to, interfering with the white-haired, handsome villain's exorcism of Cursed Spirits and recruitment of new subordinates.
He wiped out the villain's capable subordinates, the higher-ups of the jujutsu world, and encouraged the protagonist, Jogo, to fight him and cause trouble. After all, protagonists had plot armor.
He even resurrected the Cursed Spirit User who had been a sacrificial pawn, and discussed plans to take down the villain with him...
But the enemy was simply too strong. Amamiya ultimately failed, and even the protagonist died...
Looking at the System panel showing that the mission had succeeded, Amamiya Kei felt there must have been a bug. Otherwise, with the villain still running around in perfect health, how could he have completed the mission?
