character: koakuma. A medium shot captures koakuma standing in the center with a calm, unfocused gaze. She is a female demon with long red hair, pointy ears, glowing red eyes, and large bat wings extending from her back. She is dressed in a formal anime-style librarian outfit consisting of a white collared shirt with a red necktie, a black vest, and a long black pleated skirt. She is also wearing dark tights. The composition places the character in the foreground. Behind her is a grand, spacious library with towering wooden bookshelves that extend into the distance, filled with books of all kinds. The shelves are organized in long rows, creating lines that guide the viewer. Warm lighting filters in from a large window, illuminating floating dust motes in the air.
