College student Lin Yan wakes up to find that he has transmigrated into a crossover universe combining Detective Conan, Jujutsu Kaisen, K, and Bungo Stray Dogs.

He has no grand ambition to save the world. He just wants to rescue the "key figures" who were never supposed to die in this dangerous crossover world filled with bombs, cursed spirits, and supernatural abilities, and see how his arrival changes this "script" spanning multiple worlds.
