Create a close-up anime image of a yandere guy. He has long, disheveled black hair, large, sparkling eyes filled with a crazy light, pupils slightly constricted. He is dressed in classic Japanese clothing, a white shirt that has a few bloodstains on it. He has a dangerously tantalizing figure. He holds a bloody knife in his hand, his face has a creepy and maniacal smile on it, his mouth unnaturally wide and curved. In the background is a dimly lit torture room with bloodstains and graffiti on the walls. Broken books and shards of glass lie on the floor, creating an ominous and frightening atmosphere. He should seem possessed to the viewer, his eyes should be fixed on him with an expression of dangerous devotion and possessiveness. The image should be highly detailed, a masterpiece with excellent lighting and the best quality.
