Forced to Transmigrate, I Became a Jujutsu Sorcerer

Xingzi is a rather unlucky person who transmigrated for no apparent reason to Japan more than ten years in the past. An ordinary human, she had all her common sense thoroughly shattered by the Panxing Cult. After a period of despair, she met the protagonist of this world (as one idiot liked to think of himself). Thinking she'd latched onto a powerful backer, she became this conceited guy's very attentive sidekick and got along well with the students at the Jujutsu High School. What a beautiful summer day, right!? Just when she thought life after transmigrating would continue to be this wonderful, she transmigrated again. And this time, she was in the Heian-kyo era, a thousand years in the past! She'd actually become a divine maiden?!!! No, this had to be a joke, right? But when she saw that Gojo ancestor, whose face was exactly the same as her powerful backer's, the somewhat chuuni Xingzi accepted the truth with equanimity. In the name of the divine maiden, she would save all living beings. Her main task was to defeat the calamity and evil god of the time, Ryomen Sukuna. After painstakingly leveling up all the way, she finally gained followers and influence of her own. But little did she know that the idiot she'd been was already a puppet of the jujutsu world's higher-ups. Once they were done using her, they cut her loose. She became a pawn to be discarded, her soul torn to pieces, never to be reborn. "Wait, wait! Then what's going on with me now? I, Xingzi-sama, am still alive and well!" Xingzi, a current high school girl, protested in dismay after just exorcising a cursed spirit. "Cursing me to die like that will bring you terrible luck!" Note: The story includes some simple timeline shifts. The blurb isn't the whole story, and of course the pairing is Gojo Satoru~ Theme: Superstition is not to be trusted
