Curse Returns, a gamble from the start, I awaken dual spells

This book is similar in style to the original work, not a traditional power-up/power fantasy, with a slower pace and a focus on character development. Sato Rito, a first-year student at a high school specializing in sorcery. The story of an ordinary person struggling to survive in the world of sorcery. ————Transmigrated to Jujutsu Kaisen, three months before the Shibuya Incident. No system, no talent, just an ordinary person who can't even see a sorcerer. Sato Rito knows very well that in three months, he will become one of the thousands of ordinary people on the streets of Shibuya, a cold statistic of casualties. Waiting for Gojo Satoru to save him? Unrealistic. Waiting for the Shibuya Incident to mass-produce him into sorcerers? That's waiting to die. Only one path lies before him. Enter the dark, damp sewers, find the special-grade sorcerer covered in stitches. Bet his own soul for a chance to live. "Main, give me power." "In exchange, I can become your most interesting toy."
