Conan: I Am the Dead

I remember there was a Conan fanfic with the same setting a long time ago. It seemed to be called "Conan: I Really Don't Want to Die" or something. I can't remember the name because it has been taken off the shelves, but there is no system and no "real world". The first one possessed seemed to be the boss of the art museum who killed him. Later, he possessed several people and then possessed Miyano Akemi. Then he possessed Narumi, who disguised himself as a woman and escaped from Moon Shadow Island directly. Then he was cut off. I have been wanting to find one with similar settings for many years, but I didn't expect that there is a new one. Unfortunately, the update looks very confusing 😐
