When ordinary high school student Lin Xia opened her eyes, she found that she had actually entered the world of "Detective Conan" - becoming an inconspicuous transfer student at Didan High School. To make matters worse, as soon as she arrived at school, she bumped into Kogoro Mouri pointing at the body and shouting "You are the murderer", while Conan Edogawa was glancing at her, "a stranger who suddenly appeared" with his half-moon eyes.
She knows the direction of all the main plots, the hiding place of the black organization, and can even recite Conan's commonly used "anesthesia needle routine". But when the real death case happened in front of her eyes, when Haibara Ai asked with vigilant eyes, "You seem to know too much," and when Gin's Porsche 356A passed by, Lin Xia realized: knowing the plot does not mean he will survive.
In order to gain a foothold in Tokyo, which is full of murder cases, she was forced to follow Conan to find clues, help the young detective team "clean up the mess", and even accidentally became a "temporary assistant" of the Mori Office. But as her contact with Conan and Haibara deepened, and as she watched those who were supposed to die according to the plot once again face danger, she tightened her grip on the notebook filled with clues secretly written down in her pocket——
"Now that it's here, we can't let tragedy happen again."
But she didn't notice that Conan's eyes had already narrowed behind his lenses: What secret did this transfer student hide? And on the rooftop of a high-rise building in the distance, Absinthe was smiling at the communicator: "There's another interesting little mouse..."
