勝ち誇る笑み

A modern Japanese anime-style close-up illustration of a young girl with long, light blue hair wearing a flowing white dress. She is resting her chin on one hand, leaning on a brown wooden table in a relaxed pose. Her expression has a more intimidating, triumphant smile, exuding a sense of superiority and dominance. Her head is slightly tilted, and she looks sideways with a piercing and confident gaze. Surrounding her are countless glowing mathematical formulas, adding a mysterious and intellectual atmosphere. The table has a natural wood grain finish, and the background remains completely black, enhancing the dramatic and intense focus on her face and expression.
