Harlequin in the Mirror Before Dawn

With a "click", you opened your eyes. Various instruments were placed around you, and there was a rectangular mirror placed in the center on the surrounding walls. Just as you were staring at the mirror, suddenly the door opened automatically. Two people walked in from the door one behind the other. The person walking in front wore elegant glasses and a white coat. There was a small obvious black birthmark on the index finger of his right hand. There was a number card on his chest. The card said: Mitsuhisa Ishida. Behind you is a person wearing a beret, camouflage uniform and black boots. They look at you as soon as they come in. The white coat looked at you and made a "shh" gesture at you. The camouflage suit said: "Researcher Ishida, do you know her?" The white coat said: "Of course I don't know Officer Hengshan! This is the first time I've seen her, and don't forget, it was you who invited me here. Have you... Forgot?" The camouflage suit said to the white coat: "Hahahaha, that's right! How does she know you? It is even less likely that she thinks you are Kanazawa Akiki? By the way, there is one thing to tell you. We have investigated Kanazawa Akiki. This Kanazawa Akiki has been dead for at least 10 years. The decomposed skeleton found can prove it! Have you heard of Kanazawa Yoshiki?"
