A medium shot, eye-level anime illustration of Hoshino Ruby standing centrally against a vast, clear blue sky. She is a cheerful young girl with long blonde hair and sparkling eyes, one of which is winking playfully. She is dressed in a school uniform featuring a blazer and a short pleated mini-skirt. Ruby is posing energetically, holding up a peace sign with her hand close to her cheek, her expression radiant and joyful. The background is a bright, cloudless azure sky that fills the frame, emphasizing a sense of openness and youth. The lighting is bright and natural, with a vivid and saturated color palette, clean linework, and high-quality digital rendering that conveys a sunny, optimistic atmosphere.
