Please generate a close-up, portrait-style anime image of a yandere girl. She has long, disheveled black or dark brown hair, with large, gleaming eyes filled with a crazed light, and her pupils slightly contracted. She wears a classic Japanese high , a white shirt with a sailor skirt that has some blood stains. She has a dangerously alluring figure. She holds a bloodied knife in her hand, with an eerie and maniacal smile on her face, her mouth unnaturally wide and twisted. The background is a dimly lit classroom with blood stains and graffiti on the walls. The floor is littered with broken books and glass shards, creating a sinister and terrifying atmosphere. She should appear intensely obsessed with the viewer, her eyes fixed on them with a look of dangerous devotion and possessiveness. The image should be highly detailed, a masterpiece with excellent lighting and the best possible quality.
