character: watatsuki_no_yorihime, A medium shot, 3/4 view of Watatsuki no Yorihime, whose entire body—including her skin, face, hair, clothes, and limbs—has been completely transformed into polished black obsidian. She is captured in a state of panic, her expression frozen in a look of alarm and distress, though her facial features are now carved from seamless, glossy volcanic glass. Her eyes, including the pupils and sockets, are entirely covered by black obsidian, rendering the eyeballs and their contours invisible beneath a solid, dark crystalline surface. Her long hair, typically in a high ponytail with a bow, is now a frozen mass of jagged black obsidian. She possesses a large chest (G-cup), the contours of her bust and attire defined only by the reflective, obsidian material. She stands rigidly, her hands frozen in a gesture of surprise. The background is a neutral, void-like space to emphasize her reflective surface. The lighting is sharp and high-contrast, creating bright, specular highlights on the obsidian's smooth, glass-like texture, evoking a cold and suffocating atmosphere.
