Prompt (Good enough, no negative prompt needed)
A close-up anime portrait of a boy with glowing red eyes, surrounded by dark energy. He is seen mid-motion, tracing "Koros sama" in glowing, blood-red letters in the air. The dark background blends into the shadows around him, with only the eerie red glow of the letters and his eyes providing light. His face is partially in shadow, with dark hair slightly floating from the energy emanating from him. The mood is dark, sinister, and powerful.
