Houkago no Kagamizou Kaii: Doppelganger

A young boy enduring relentless torment and bullying at school finds his life taking a dark, unexpected turn when he stumbles upon a mysterious printer hidden away inside an abandoned classroom. Driven by desperation and resentment toward his abusers, he decides to test the strange device by sending it a photograph of one of his primary tormentors, a girl named Shinomiya. To his utter astonishment, the machine successfully processes the image and produces a physical, exact replica of the girl's skin, perfectly capturing every detail of her appearance, from her facial features to her body. This chilling discovery sets off a surreal and unsettling chain of events, plunging the protagonist into a psychological dilemma where the boundaries between reality, vengeance, and the supernatural begin to blur inside the empty halls of the school.
